Internal Quality of Casting Billet

Internal Quality of Casting Billet

The internal quality of the billet refers to the low power structure,component segregation, central loosening, central segregation and cracks. The formation of defects in billet involves the action of heat transfer, mass transfer and stress in solidification. After the billet is thermally processed, some defects can disappear, some are deformed,…
