Method for producing single-sided composite stainless steel cold rolling base stock

Abstract

The invention relates to a method for producing a single-sided composite stainless steel cold rolling base stock. The method comprises the following steps of: firstly, selecting carbon steel or low-alloy steel as a substrate, processing oxidation layer on surfaces of the substrate and a compound plate, and assembling and stacking the compound plate and the substrate; secondly, drilling, detectingleakage and vacuumizing; and finally, performing hot continuous rolling, coiling a hot rolled strip on a double coiling opening production line and trimming to form two strip coils serving as the cold rolling base stock, wherein the material and thickness of the cold rolling base stock can be combined freely to meet the requirements of different users, and the cold rolling base stock is widely applied in industries of petroleum, chemical engineering, salt industry, water conservancy, electric power and the like. The single-sided composite stainless steel cold rolling base stock is used as a resource-saved product to reduce the consumption of precious metal, reduce engineering cost substantially and realize the perfect combination of low cost and high performance, so the cold rolling base stock can create great social benefits.

Description

technical field [0001] The invention relates to a production method of a single-sided composite stainless steel cold-rolled base material. Background technique [0002] In the traditional production method, the stainless steel strip blank is processed through rolling, heat treatment, edge trimming and slitting; the roll unit adopts four-roll precision rolling unit and other production methods, the surface quality of the steel strip is poor, and the output is difficult to increase; the hardness is difficult to control , can not meet the requirements of customers; in the rolling production process, in order to improve the surface quality of the steel strip, usually spray vegetable oil or lubricating oil, etc., so the production cost is high; the flatness of the steel strip is low, during the rolling process The emulsion is used as a lubricant. The emulsion is a mixture containing lubricating oil, antioxidants, anti-wear agents, fatty acids and water. The composition is rel...

[0002] In the traditional production method, the stainless steel strip blank is processed through rolling, heat treatment, edge trimming and slitting; the roll unit adopts four-roll precision rolling unit and other production methods, the surface quality of the steel strip is poor, and the output is difficult to increase; the hardness is difficult to control , can not meet the requirements of customers; in the rolling production process, in order to improve the surface quality of the steel strip, usually spray vegetable oil or lubricating oil, etc., so the production cost is high; the flatness of the steel strip is low, during the rolling process The emulsion is used as a lubricant. The emulsion is a mixture containing lubricating oil, antioxidants, anti-wear agents, fatty acids and water. The composition is relatively complex. Although the emulsion can clean the slag inclusions of the hot-rolled steel strip itself and play a role in cooling and Lubrication, but because it is a mixture, it will still leave dross on the surface of the steel strip, so that the shape and brightness of the steel strip are not enough
