Cold Rolled Steel Coil And Sheet
Cold Rolled Steel Coil
Cold rolled steel plates are steel plates produced through cold rolling processes, referred to as cold plates.
The thickness and width of cold rolled carbon steel plates 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 Steel sheet can be divided into cold rolled steel coil with full hard and common steel cold rolled coil.

Cold rolling is processed and rolled on the basic of hot rolled steel in coils. Generally speaking, it is a process of hot rolling -pickling-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 dipped galvanized coils; 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 dipped galvanized steel sheets, color coated steel coil and stock resistant complex steel sheet etc, which enjoys the good quality of artistic and high anticorrosion.
Advantages of cold rolled steel plate:
1. Cold rolled carbon steel coils have product standards and uniform thickness, which can fully meet the requirements of high-precision tolerances.
2. Ultra thin strips that cannot be produced by hot rolling can be obtained, and the thickness can be less than 0.001mm.
3. The surface quality of cold rolled products is excellent, and there are no defects such as pitting and pressed oxide scale that often appear in hot-rolled coils. Moreover, coils with different surface roughness can be produced according to user requirements to facilitate the following process of processing.
4. The coil pitch of cold-rolled plates has excellent mechanical properties and process properties, high strength, low yield limit, and excellent deep drawing properties.
5. It can achieve high speed rolling and full continuous rolling, with high productivity.
Cold rolled coils are used for:
1. Manufacture of automobile parts: automobile chassis, doors, roofs, hoods, body structural parts and other components.
2. Manufacturing building structural parts, roofs, wall panels and other materials.
3. Manufacture various mechanical parts, such as gears, shafts, chains, etc.
4. Added steel: Cold rolled plates can be used as raw materials for electron microscopes, hot mirrors and other steel products, and added into various specifications of steel.
