Hot Rolling Process Flow Chart
Advantages of HRC
Hot rolling can destroy the casting structure of the ingot, refine the grain of the steel, and eliminate the defects of the microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic to a certain extent; the bubbles, cracks and porosity formed during casting can also be welded under the action of high temperature and pressure. Therefore, the hot rolled coil has excellent properties such as high strength, good toughness, easy processing and good weldability.
