Horizontal & Vertical Continuous Casting Production

THE PROCESS. To begin, the casting crucible is furnace-fed by an under-pouring method from a continuous melting source. The molten metal is maintained at the correct holding temperature in the crucible, which is completely enclosed. Any dirt, dross or gases present rise to the top of the melt and are left behind in the casting process.
