First of all the advantages of hot-rolled flat steel can destroy the ingot casting organization, grain refining of steel, and eliminating the defects of the microstructure, which makes steel group is close-grained, mechanical performance is improved. This improvement is mainly manifested on along the rolling direction, so that the steel to a certain extent, is no longer isotropic body; Pouring formed bubbles, cracks and loose, can also be used in high temperature and pressure are welded together.
Second cold-rolled flat refers to the room temperature, after cold drawn, cold bending, cold drawn cold working steel sheet or strip processing into various types of steel. Advantages: molding speed, high output, and does not damage the coating, can be made into a variety of cross section form, to meet the needs of the conditions of use; Cold can make produce very big plastic steel "deformation, thus improve the yield point of steel.
Finally is the main difference between hot rolling and cold rolling, cold rolling into sections to allow local buckling section, which can make full use of the bar buckling bearing capacity after; And hot car payments are not allowed to cross section of local buckling occurred. The causes of hot rolled steel and cold rolled steel residual stress is different, so the distribution of cross section also have very big difference. Cold-formed thin-walled steel cross section on the residual stress distribution is curved, and hot rolled steel or welded steel residual stress distribution on cross section is a thin film.Hot rolled steel free torsional rigidity is higher than cold rolled steel, so the torsion properties of hot-rolled steel is better than cold rolled steel.
