Introduction To The Advantages Of Hot Rolled Steel Round Bars

Rolling classification: According to the rolling motion,Hot rolled steel round bars the rolling methods are divided into: longitudinal rolling,Hot rolled steel round bars cross rolling, and cross rolling. The longitudinal rolling process is a process in which metal passes between two rolls that rotate in opposite directions and produces plastic deformation between them. Cross rolling: the direction of movement of the rolled piece after deformation is consistent with the direction of the roll axis. Skew rolling: The rolling piece moves in a spiral, and the rolling piece and the roll axis are not angled. According to the metal state,Hot rolled steel round bars there are: hot rolled and cold rolled.

It can destroy the casting structure of the steel ingot,Hot rolled steel round bars refine the grain of the steel, and eliminate the defects of the microstructure,Hot rolled steel round bars 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; bubbles,Hot rolled steel round bars cracks and looseness formed during casting can also be welded under high temperature and pressure.
