Cold Rolled Steel Coil
Cold rolled coil is a product made from hot rolled coil and rolled below recrystallization temperature at room temperature. It is mainly used in automobile manufacturing, electrical products, etc. Cold rolling is rolling at recrystallization temperature, but it is generally understood as rolling using normal temperature rolling materials.
1.The cold-rolled coil products are accurate in size, uniform in thickness, and the thickness difference of the coils generally does not exceed 0.01-0.03 mm or less, which can meet the requirements of high-precision tolerances.
2.It is possible to obtain extremely thin strips that cannot be produced by hot rolling (up to 0.001 mm or less).
3.The surface quality of cold-rolled products is superior, there are no defects such as pitting, hot-pressed iron oxide,etc.,which are often found in hot-rolled coils, and coils of different surface roughness (glossy or hemp) can be produced according to user requirements.Rough surface, etc., to facilitate the processing of the next process.
4.The cold rolled plate has a good mechanical properties and process properties (such as higher strength, lower yield limit, good deep drawability, etc.).
5.High-speed rolling and full-continuous rolling can be realized with high productivity.
