Cr CRC cold steel coil
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.
Hot rolled coil is made of strip steel by roughing mill and finishing mill group after heating with plate defects
(mainly continuous casting defects) as raw materials. From finishing the last hot steel strip mill out through
laminar flow cooling to the set temperature, which consists of the winder
coil, steel coil after cooling, according to the different needs of users, with different finishing line (flat, straightening,
transverse or longitudinal cutting, inspection, weighing, packaging and logo, etc.) and become a steel plate, flat roll
and longitudinal cutting steel strip products. Hot rolling steel plate products have high trength, good toughness, easy
processing and forming and good weldability and other excellent properties, so the north is widely used in ships,
automobiles, Bridges, construction, machinery, pressure vessels and other manufacturing industries.
