Cold Rolled Steel Coil And Sheet

Brief Description:

Cold rolling is made of hot-rolled coils as raw materials and rolled at room temperature below the recrystallization temperature. Cold-rolled steel plates are steel plates produced through cold-rolling processes, referred to as cold plates. The thickness and width of cold-rolled sheet are determined according to the equipment capacity of each factory and market demand. Cold rolling is processed and rolled on the basic of hot rolled coils. Generally speaking, it is a process of hot rolling -pickling-cold rolling.

Cold-rolled strips are widely used, such as automobile manufacturing,electrical products, rolling stock, aviation, precision instruments, foodcans, ect. Cold rolled steel sheet is the abbreviation of ordinary carbon rolled plate, also called cold rolled plate.

Product Description

For short pitch precision roller chains (A series & B series), Walking tractor & rotovator chains, A & B series roller chains for combines, ZGS38 combines chains, rice harvester chains, S, C, A, CA type steel agricultural chains and so on.

Cold-rolled sheet can be divided into full hard coil and common cold rolling.

Firstly, full hard coil uses hot rolled coil as raw material, via pickling to remove iron dross and make continuous rolling, increase the intensity and hardness of full hard coil, which can be used as the simply deformed parts and the raw material of hot-dip galvanized manufacturers; Secondly, common cold-rolled sheet adopting continuous annealing or bell type annealing to eliminate hardening and rolling stress, meet the relevant criterion of biomechanical property, which is suitable for the further processing that uses cold-rolled steel sheet as substrate, and then making high added value products. For instance, hot-dip galvanized sheet, color coating steel sheet and stock-resistant complex steel sheet etc, which enjoys the good quality of artistic and high anticorrosion.
