Abstract
Description
technical field
[0001] The invention relates to a method for processing chromium-nickel austenitic stainless steel continuous casting slabs. Background technique
[0002] In many applications of stainless steel, there are high requirements for the surface quality of the product, not only because of the need for corrosion resistance, but also because of the requirement for the surface finish and aesthetics of the product. The surface quality of stainless steel continuous casting slabs has a great influence on the surface quality of its final products, especially cold-rolled products.
[0003] When ordinary carbon steel and low-alloy steel continuous casting slabs are heated in the heating furnace of the hot rolling process, a thick layer (several millimeters) will be uniformly oxidized on the surface of the slab, and then this layer of iron will be oxidized by high-pressure water spraying. Phosphorus removal. Its effect is equivalent to peeling off a surface layer with a th...
