Advantage : It can destroy the cast structure of the ingot, refine the grain of the steel and eliminate the defects of microstructure, so as to make the steel structure compacted and improve its mechanical properties.The improvement is mainly along the rolling direction so that the steel is no longer isotropic to some extent.Bubbles, cracks and looseness formed during pouring can also be welded under high temperature and pressure.

Production of steel for general frames and welded frames, used in the manufacture of iron frames, Bridges, ships and vehicles
