Abstract

The invention belongs to the field of metal material machining equipment and provides a machining method for a novel heat-resistant stainless steel annealing pot and the manufactured annealing pot to solve the problem that in the prior art, a movable annealing pot is repeatedly subjected to the circulation process of heating, heat preservation and slow cooling to the normal temperature, so that the movable annealing pot is prone to breaking and being out of work. The annealing pot comprises a pot bottom and a pot body which are welded integrally, the pot body is a large-caliber seamless stainless steel tube which is 16-20 mm thick, and a quartz sand permeation fusion layer and a quartz sand layer are arranged on the outer surface of the pot body. The pot body is formed in an integrally poured mode, and the pot body and the pot bottom are welded; the outer surface of the pot body is covered with a quartz sand refractory material protective layer, molten steel on the surface of the pot body and quartz sand form the permeation fusion layer at a high temperature, and the quartz sand particles not fused or permeating form the quartz sand layer. The novel heat-resistant stainless steel annealing pot is good in mechanical performance in a high-temperature environment, has good heat-impact resistance, high-temperature resistance, oxidation resistance and corrosion resistance. The pot body does not deform, and is good in sealing performance and annealing quality. The service life is 3-5 times that of a common annealing pot, the annual use cost is decreased, and the production efficiency is improved.
