Cold-rolled steel strip processing technology

Abstract

The invention discloses a cold-rolled steel strip processing technology. The cold-rolled steel strip processing technology is characterized by comprising the following steps of: conveying a steel strip of which the thickness is 3mm to a left winding machine through an unwinding machine rotating forwards; enabling the steel strip to pass through a left turning roll, and conveying the steel strip into a left tensiometer for tension test; conveying the steel strip into a left speed meter for speed measurement; conveying the steel strip into a left thickness gauge for thickness test; conveying the steel strip into a six-roll reversible cold rolling mill for rolling; enabling the steel strip to pass through a cooling device on the six-roll reversible cold rolling mill for cooling; conveying the steel strip to a right tensiometer for tension test; conveying the steel strip into a right speed meter for speed measurement; conveying the steel strip into a right thickness gauge for thickness test; performing reverse motion for rolling; and after rolling for seven times, winding the steel strip through a right winding machine to complete the rolling process. The cold-rolled steel strip processing technology has the effects that the rolled plasticity of the steel strip is improved, and the rolling quality of the steel strip is further improved.

Description

technical field [0001] The invention relates to the field of steel production and processing, more specifically, it relates to a cold-rolled steel strip processing technology. Background technique [0002] At present, the thickness range of cold-rolled steel sheets is generally 0.1-3mm; it is the product with the largest output and the most widely used in steel products, and is often used in automobile covers, refrigerators, washing machines and other household appliances shells, steel furniture, various building materials, etc. It can also be used to process steel pipes, coated steel plates, etc. [0003] The production process of steel cold-rolled sheet is hot-rolled coil, pickling to remove iron oxide scale on the surface of hot-rolled coil, cleaning, drying and trimming, rolling into coil, and then rolling by cold rolling mill At present, in the cold rolling production process of rolling 2.75mm hot-rolled coils and plates into 0.15mm steel strips, the required thickness...

Problems solved by technology

[0003] The production process of steel cold-rolled sheet is hot-rolled coil, pickling to remove iron oxide scale on the surface of hot-rolled coil, cleaning, drying and trimming, rolling into coil, and then rolling by cold rolling mill At present, in the cold rolling production process of rolling 2.75mm hot-rolled coils and plates into 0.15mm steel strips, the required thickness is achieved through repeated rolling, but the steel plate will generate a certain amount of heat during the rolling process , it is easy to soften and recrystallize during cold rolling, resulting in a decrease in the plasticity of the steel strip and affecting the rolling quality of the steel strip
