(FR) PROCEDE ET APPAREIL DE COULEE DE RONDS, BRAMES ET AUTRE
Abstract
(EN) 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 controlled 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 section 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.
(FR) Procede et appareil de coulee de produits metalliques semi-finis ou un piston resistant au metal en fusion (27, 100, 161, 163) est dispose a proximite du sommet d'une cavite (26, 162, 164) dans un moule permanent (20, 150), un reservoir (36, 203) de metal en fusion est cree et maintenu sur le piston, et le piston est force de descendre dans la cavite a une vitesse controlee de telle sorte que le metal en fusion (35) entre et remplisse la cavite au-dessus du piston. Lorsque le piston atteint le fond en fin de descente, une piece coulee ayant une section uniforme est formee. Pendant le refroidissement et la solidification du produit coule, le piston est utilise de preference pour exercer une force dirigee vers le haut sur la piece coulee, ce qui peut faire saillir legerement le haut de la piece coulee hors du moule pendant qu'elle refroidit.
