In order to allocate resources reasonably and realize the layout of the company's global manufacturing system

In order to allocate resources reasonably and realize the layout of the company's global manufacturing system, Lizhong Group plans to build a new annual production capacity of 3.6 million ultra-lightweight aluminum alloy wheels in the Interpuerto (Customs) Industrial Park in Monterrey, Mexico. After the project is completed, it will help the company to effectively avoid the high anti-dumping duties of the EU, India and other countries, and enhance the international competitiveness of the company's aluminum alloy wheels; at the same time, the production capacity layout in Mexico will help the company to further expand overseas markets, improve the overseas supply system, and strengthen the company. The in-depth cooperation between aluminum alloy wheels and overseas high-end customers can hedge against the impact of high sea freight caused by the epidemic, reduce supply chain risks, and increase the international market share and profitability of aluminum alloy wheel products.

A prerequisite for the manufacture of 7-series aluminum alloys is the manufacture of high-purity primary aluminum.

Aluminum bars are widely used in many aluminum industries

In terms of production capacity: As of now, the production capacity of aluminum rods in China has reached 33 million tons. During August, no new projects have been launched or put into production in China. At the same time, in terms of scale, Shandong, Inner Mongolia, and Xinjiang are still the largest. The top three output bases in my country at this stage.

Due to the characteristics of raw materials, the layout rhythm of aluminum rods still changes with the changes of electrolytic aluminum. At present, although Shandong, Inner Mongolia, and Xinjiang mentioned above are still the largest production bases in my country, due to the local electrolytic aluminum The development of aluminum bar has reached its peak, and it is reported that there may be no new indicators and new production capacity development in the future, so the expansion of aluminum rods in such areas has also pressed the pause button. (Especially take Shandong and Xinjiang as an example, and Inner Mongolia still has some plans for the implementation of new electrolytic aluminum production capacity. Correspondingly, the development of surrounding processing enterprises will take time to pay attention.)

Compared with the stagnation of the development of the old bases, the focus of the market is more on the emerging territories that have been rising in recent years, including Guangxi and Yunnan. The share of aluminum rods is also in the stage of gradual growth. At present, the completed production capacity of aluminum rods in Guangxi has successfully squeezed into the top five in the country. In addition, Yunnan's aluminum chain blueprint deduction will also help the local aluminum rod industry. The scale of continuous expansion shot up.

In terms of production: From August to the present, the weekly production of domestic aluminum bars has gradually shown a downward trend since the middle and early months of the month, which covers epidemic control, equipment maintenance, plant security inspection, power restriction management, demand orders, and corporate funds, etc. A variety of factors have led to a decline in the output momentum of enterprises in some regions.

In the first week of August, the weekly production of aluminum rods showed an increasing trend compared with the end of July. Some early production reduction/shutdown projects had restarted production. By the middle and early months of the month, the weekly production of the month generally stabilized, and then. However, it started a gradual downward rhythm. As of last week, according to Mysteel's research, the weekly production volume reduction has reached more than 10,000 tons.

Through comparison, we can see that the weekly aluminum bar production in Inner Mongolia, Ningxia, Qinghai, and Sichuan regions showed different reductions compared to the beginning of the month until the end of August, among which the reduction in Sichuan province. It is particularly prominent, and the local mainly due to high-temperature power cuts, leading to the closing of enterprises one after another, thus the overall market has entered a staged vacuum period. In addition, due to the deployment of the seven aluminum requirements, rod factories in Inner Mongolia were subject to security inspections one by one. During the period, there was a slight impact on the production of enterprises. At the same time, the natural gas pipelines of individual enterprises were damaged due to the impact of heavy rain, resulting in a temporary interruption of production. The price factor, there is a situation where the product is switched to production on the way.

Factory warehouse: Since August, the inventory of Chinese aluminum rod manufacturers has gradually increased, and as of last week, according to Mysteel statistics, the total factory warehouse has approached 60,000 tons, and this does not include platform retention. quantity.

Judging from the distribution of factories and warehouses, it is mainly concentrated in the northern market at this stage, including Xinjiang, Gansu, Inner Mongolia, and Ningxia province. In addition, there are also some quantifications in Shandong, Guangxi, Yunnan, and Guizhou.

It is understood that the main reasons for the accumulation of factory warehouses in the northern market are: 1. Epidemic control and transportation are hindered; 2. Green products such as coal, melons, and fruits are given priority, and it is more difficult to find vehicles; 3. Insufficient orders reduce the efficiency of downstream delivery; 4. Weather Due to road conditions, the factory has been slowed down.

To sum up, the production and operation of aluminum bars in China in August has shown a certain rhythm of fatigue, and the supply side is under severe pressure. Although the future process is accompanied by a slight quantitative reduction, under the current situation of weak demand and thin trading, the supply of goods is weak. There is still a surplus, and aluminum rod manufacturers are facing various pressures, and it can be said that they are moving forward with a heavy load. Combined with the operating expectations in the last few days of August, the author predicts that the monthly production of aluminum bars in China in August 2022 will be 1.25-1.3 million tons.

Aluminum bars are widely used in many aluminum industries, but they are made from high-purity aluminum. Thus producers need to use degassing units to reduce hydrogen in aluminum liquid, otherwise, there are many bubbles in aluminum bars. Also, aluminum bar producers need to use deep bed filters or ceramic foam filter boxes to filter impurities from the aluminum liquid.

The railway rake made from lightweight, high strength aluminium alloys is 3.2 tonnes lighter than a steel rake

On Tuesday, August 23, Mr Kumar Mangalam Birla announced in the 63rd Annual General Meeting of Hindalco Industries that the company developed India’s first all-aluminium railway wagon. The railway rake made from lightweight, high strength aluminium alloys is 3.2 tonnes lighter than a steel rake.

Hindalco builds India’s first all-aluminium railway rake, says Kumar Mangalam in 63rd AGM

According to Mr Mangalam, the railway rake made of aluminium will be a game changer, saving 1,500 tonnes of carbon emissions a year. It will also improve the logistics efficiency of coal transportation and accelerate India’s decarbonisation journey, said Birla.

He calculates that if five per cent of the 2 lakh railway wagons that India government plans to introduce are of aluminium, around 15 million tonnes of carbon emissions can be saved in a year.

Hindalco’s environmental, social and governance (ESG) commitments include achieving net carbon neutrality, water positivity, biodiversity conservation and zero waste to landfill by 2050.

Future of aluminium in transportation sector

Kumar Mangalam also noted in the meeting that Hindalco reserved a total capital expenditure of about $8 billion for its arm Novelis and India. Novelis has discovered potential investment opportunities of $4.5 billion, while its India arm has identified opportunities of nearly $3 billion.

Adtech ceramic foam filters helps Sichuan electricity shortage

Recently, Sichuan Province issued a sudden notice to expand the scope of industrial enterprises to let electricity to the people. The current estimated duration is from August 15th to 20th. The Ningde Times Sichuan Yibin factory also stopped production due to power cuts.

Credit Suisse said the impact of the curtailment on commodities will be less significant than in 2021 when this round of power shortages was caused by high temperatures, and in 2021 because of "double control of energy consumption". In addition, downstream demand this year is relatively weak. However, SMM told reporters that most companies have officially entered a five-day shutdown state from 0:00 on August 15, and considering that ternary, iron-lithium, etc. still need a certain amount of time to wait for the kiln after the production line cools down As the furnace heats up, some manufacturers say that this round of power cuts will actually affect the company's output for 7 to 8 days.

The battery industry chain is impacted

Recently, the southwest region of the country has continued to be hot and precipitation has decreased. Affected by this, the power supply in Sichuan is tight. In order to ensure the safety of the power grid and the electricity consumption for people's livelihood, Sichuan has canceled the demand response of active staggered peak avoidance since August 15, and expanded industrial enterprises in 19 cities (prefectures) in the province (except Panzhihua and Liangshan) to provide electricity to the people. The implementation time is from 00:00 on August 15th to 24:00 on the 20th.

Molten Aluminium Degassing unit of Adtech

Molten aluminium (Al) is an extremely reactive substance. The molten metal is so reactive that it will readily decompose water in the atmosphere, or moisture on wet tools, releasing hydrogen into the melt. Even small volumes of water condensing on a crucible furnace or transfer ladle can affect the quality of final castings. Excess hydrogen can affect the distribution of porosity, and the total amount of shrinkage, ultimately increasing scrappage. Eliminating gas absorption from molten aluminium is unfeasible. So, metallurgists tend to focus on preventing hydrogen introduction into the melt and removing as much as possible prior to casting.

Why aluminum degassing is Important

Aluminium and its alloys are susceptible to a unique form of chemical corrosion known as hydrogen-induced cracking, which is caused by the gradual diffusion of hydrogen (H) molecules through the metal’s crystal lattice. This creates a localised flaw within the alloy that can significantly impair both its tensile strength and ductility, reducing its fracture toughness, thus increasing the risk of surface fracture. While solid, the hydrogen solubility of aluminium is negligible. Molten aluminium, however, is an incredibly reactive substance that actively decomposes moisture to produce hydrogen (H).

Explaining Molten Aluminium Degassing

Molten aluminium degassing is an essential process in alloy casting. It is carried out through one of two methods: flux or rotary degassing. An online degassing unit comprises a motorized drive and a hollow, rotating shaft that directly injects an inert gas such as argon (Ar) or nitrogen (N2) into the aluminium melt. The combination of the shaft’s rotating motion and the purging of this inert gas causes a high volume of bubbles to form within the melt.

Hydrogen that has dissolved in the molten aluminium then diffuses into these bubbles and separates from the liquid phase. This provides a more efficient and clean method of hydrogen removal compared to flux degassing.

Adtech degassing unit

Degassing molten aluminium can be problematic as it must be carried out in situ when the melt is maintained at temperatures exceeding 700°C (1292°F). This can induce chemical attack and thermal degradation of the rotor shaft and purge valves. Silicon nitride (Si3N4) degassing components have been widely used, but there are alternative refractory materials that are more cost-effective while offering almost identical oxidation resistance and high-temperature performance.

The ENA is suitable for system pressures from up to 0,8 bar. This makes the SOTEX ENA particularly suitable for use in heating systems in international horticulture. In these systems low pressures (about 0,8 to 1 bar) and hose systems are common networks. A hose just causes more air inlet into the heating water system than a steel heating system. The ideal situation for applying a vacuum de-aeration unit. Air in these heating systems causes poor water circulation and reduces power transmission. The SOTEX ENA prevents these inconveniences. Clients can choose between two ways of degassing unit;

- Turbo-degassing: rapid and effective degassing after installation, without gaps between the de-aerating cycles.

- Normal venting: energy efficient operation by programming longer breaks between the de-aerating cycles. The user of the a can choose between two ways of

When using a ceramic foam filter, install the Ceramic Foam Filters For Casting in the filters casthouse. Pour the molten aluminum into the filter box through a ceramic foam filter. The filter traps the fine particles in the molten metal. After the casting operation is completed, the aluminum slag remaining in the ceramic filter forms an almost solid piece of aluminum.

Ceramic Filter 20 Inches is the most commonly used ceramic foam filter in the aluminum casting industry. Ordinary aluminum casting usually uses 10-40ppi ceramic filter plates. Aviation and high-quality aluminum materials usually use 30-60ppi ceramic filter plates.

Ceramic foam filters can remove large amounts of such inclusions from molten aluminum. Foam ceramic filtration technology has become the main method of filtering commercial aluminum alloys worldwide. Because of its low installation and operating costs and ease of use, the technology quickly expanded to aluminum foundries of various types and levels of complexity.

Over the years, it has been steadily developing towards the use of finer pore ceramic foam filters to provide higher melt cleanliness, which is a requirement for the continuous improvement of the quality of aluminum processed products. For example, in the application of aluminum can body panels, 40 and 50 holes per inch (PPI) foam filters are now commonly used in panel production. In addition, a finer pore filter is currently being evaluated. However, the use of finer pore filters requires a lot of pretreatment to reduce the level of inclusions and prevent the filter from clogging prematurely or blocked by residual inclusions. Solid particles such as oxides, carbides, nitrides, and borax compounds present in metals (such as aluminum) and insoluble inclusions in liquids (such as molten salts) will significantly affect the plasticity and the final metal during rolling or extrusion deformation.
