The slag line is the part of the ladle where molten steel is in direct contact with air. Due to the temperature difference and oxygen-rich environment, the erosion rate in this area is significantly faster than in other parts. Furthermore, the tilting of molten steel and slag removal during operation cause considerable damage to the slag line. Therefore, the erosion of the slag line has always been a bottleneck problem in the steelmaking and ironmaking industries. The slag line not only experiences rapid erosion but also problems such as slagging, red-hot discoloration, spalling, and steel leakage. Slag line bricks generally refer to the refractory bricks laid in the area from the third to the eighth layer downwards from the ladle opening.

How to solve the problems of "blue line" and "inner hexagon" in the sizing process of seamless steel pipes?

In the production of seamless steel pipes, the sizing process is the final hurdle determining the dimensional accuracy of the finished produ

In the production of seamless steel pipes, the sizing process is the final hurdle determining the dimensional accuracy of the finished product. However, the traditional two-roll sizing process has long been plagued by two major quality problems: “blue lines” (surface scratches) and “hexagonal inner corner” (uneven wall thickness). These problems are particularly problematic when producing high-grade, thin-walled pipes, directly leading to a precipitous drop in yield.

Analysis of Damage Causes of 300t Ladle Slide Plate and Technical Improvements to Increase Their Continuous Use Rate

Under the background of "high efficiency and low cost" in steelmaking plants, increasing the continuous use rate of the slide plate to short

Under the background of “high efficiency and low cost” in steelmaking plants, increasing the continuous use rate of the slide plate to shorten ladle turnaround time has become an effective measure. Increasing the continuous use rate of the slide plate can not only save refractory material costs but also reduce labor intensity and tapping temperature.

Several Simple Methods to Improve the Thermal Shock Resistance of Low-Carbon Magnesia-Carbon Bricks

Thermal shock resistance is an important property of low-carbon magnesia-carbon materials, but simply improving the thermal shock resistance

Thermal shock resistance is an important property of low-carbon magnesia-carbon materials, but simply improving the thermal shock resistance may affect other properties of the material, such as oxidation resistance and slag erosion resistance.
