Problems solved by technology

In this production method, the surface quality of the steel strip is poor, and the output is difficult to increase; the hardness is difficult to control, and cannot meet the customer's requirements; in the rolling production process, in order to improve the surface quality of the steel strip, vegetable oil or lubricating oil is usually sprayed, so , the production cost is high; in addition, the straightness of the rigid belt is low because the stretch correction process is not used
In the rolling process, the emulsion is used as a lubricant. The emulsio

Abstract

The invention relates to a producing method for a stainless steel band, specifically used in war industry, automotive vehicle industry, electron industry or household electrical appliance industry, pertaining to cold rolling base plate technique field. The method is characterized in: selecting stainless steel band blank, performing a first rolling process to obtain semi-finished stainless steel bands; feeding the semi-finished stainless steel bands into an annealing oven, charging protective gas at the same time, and dividing the temperature in the annealing oven into six sections and a preheating section; performing a second rolling process after annealing to roll the semi-finished stainless steel bands into finished stainless steel bands with thickness of 0.2-0.5mm; straightening and flattening the rolled stainless steel bands, cutting and packing to be termination products. The invention is provided with a good cooling effect and reduced rolling pass which can decline the production cost and improve the product quality and yield, at the same time the surface finishment and straightness are improved, and operating requirement of users for hardness degree is satisfied.

Description

technical field [0001] The invention relates to a production method of a stainless steel strip, which is specifically used in industries such as military industry, automobile, electronics, and home appliances, and belongs to the technical field of cold-rolled substrate materials. Background technique [0002] In the prior art, in the traditional production method, the stainless steel strip blank of 304 (1Cr18Ni9) is processed through processes such as rolling, heat treatment, edge trimming and slitting; the roll unit adopts a four-high precision rolling unit. In this production method, the surface quality of the steel strip is poor, and the output is difficult to increase; the hardness is difficult to control, and cannot meet the customer's requirements; in the rolling production process, in order to improve the surface quality of the steel strip, vegetable oil or lubricating oil is usually sprayed, so , the production cost is high; in addition, the stretch correction proces...
