     Hot-rolled coil is slab (mainly continuous casting slab) as raw material, after heating by the roughing mill and finishing mill made of strip. The hot steel strip from the final rolling mill is cooled to a set temperature by laminar flow, rolled into a steel coil by a coiler, cooled steel strip, and subjected to different finishing operations according to the different needs of the user Line (flattening, straightening, crosscutting or slitting, inspection, weighing, packaging and marking, etc.) and become steel plate, flat roll and longitudinal steel products. As the hot rolled steel products with high strength, good toughness, easy processing and good weldability and other excellent performance, which is widely used in ships, automobiles, bridges, construction, machinery, pressure vessels and other manufacturing industries.
     With the hot-rolled dimensional accuracy, shape, surface quality and other new technologies to control the increasingly mature and the advent of new products, hot rolling steel, with the product has been more widely used and in the market with more and more strong The competitiveness of the.
