Strong toughness: The Cold Rolling process is combined with tempering treatment to improve the strength, toughness, and elongation of steel, overcoming the industry problem of low ductility of cold-rolled ribbed steel bars. This technical concept has also shown excellent results in the application of ordinary carbon steel cold rolling mills. The ordinary cold Steel Strip Cold Rolling Mills precisely control the rolling force and rolling temperature and combine a reasonable pass reduction to enable the steel to obtain ideal grain refinement and texture optimization during the cold rolling process, thereby significantly improving the strength and toughness of the steel.
On this basis, the ordinary Four roller Cold Rolled Carbon Steel Rolling Mill also cleverly combines the tempering treatment process, and by precisely controlling the heating temperature and holding time, effectively eliminates the residual stress generated during the cold rolling process, further improving the plasticity and toughness of the steel. This perfect combination of cold rolling and tempering enables ordinary carbon steel to maintain high strength while also having good elongation and impact toughness, meeting the mechanical performance requirements in a variety of complex application scenarios.
