Description

PROCESS AND APPARATUS FOR CASTING ROUNDS, SLABS AND THE LIKE Abstract A process and apparatus for casting semi-finished metal products in which a molten-metal-proof-plunger (27, 100, 161, 163) is disposed near the top of a cavity (26, 162, 164) in a permanent mold (20, 150), a reservoir (36, 203) of molten metal is created and maintained over the plunger, and the plunger is caused to descend in the cavity at a con- trolled rate so that the molten metal (35) enters and fills the cavity above the plunger. When the plunger reaches the bottom of its descent, a cast product of uniform cross sec- tion is formed. As the cast product cools and solidifies, the plunger is preferably used to exert an upward force to the casting which may cause the top of the casting to project slightly out of the mold as it cools.
