Advantages: It 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.
