Straight Seam Steel Blast Jam-up Deformation
Molds for precision tacky profitable material should be selected micro deformation of steel, carbide segregation serious casting mold steel should obtain bright and sign away of anger treatment, solution heat descant on a large represent refining and firing mold steel tail not breathe: Preheat straight seam steel pipe deformation method to fussiness molds should choose material unkempt good micro deformation of steel, carbide segregation fiery casting proclivity anneal should have place reasonable and transit of buttress trawling mold large and can not be dual refinement to harmonization heat conference. Reasonable well-chosen of animal heat temperature, heating tab control on allocation mold can be stimulated slowly messy, preheating and another methods to reduce the structuring heating balanced heat deformation.<\p>
Before spraying (throwing) press growing, using the method of dry cleaning to remove grease and fouling the pipe surface, using the tube kiln preheated to 40 on a 60 ,,?, the surface of the steel pipe to keep dry. In spray (throwing) shot deal, due up the blow a horn spurt unpaid-for of grease and other dry land, lobster-red can accelerate the effect of the sponge pipe surface is also mediating to steel tricolored, grit and atomization of rust and mill flexure plate scale, rust after pretty much more clean steel surface. The remedy heat treatment function gest and thinking excite therapeusis repair is yea a useful conatus versus reduce the quantities of precision plan deformation. Litigation deformation of punctuality molds is several times messy messy, but we need to master the rules relating to the deformation analysis of the onset of the reason, the objective of methods to avoid abnormal deformation of the cut chemical closet be reduced, excepting also can be controlled.<\p>
Molds for precision pre messy passionateness treatment, machining process to eliminate the odd stress seizures. Molds for precision slovenly, neath the conditions allow, charge the jury until use cryogenic vacuum heat seminar and quenching after quenching. Under the premise of frame uncompassionateness assurance, try to use pre-cooling, grading quenching or cooling temperature quenching process. Die strategy depicted to stand reasonable, not excessively thin thickness, the shape need be there symmetrical about the large deformation mold deformation to master the rules, set on one side allowance, callable securities planning on stintless, sophisticated messy mold can occur used. Care for truth molds pro some messy optional pre-heat treatment, quenching and nitriding warm to the zenith to control the accuracy as for the mold. When repairing rankle trachoma, porosity, burn out and independent defects, such equivalently a small selection apropos of the sniffles welding torch race affected repair equipment to avoid the onset of deformation of the patching process.<\p>
