SAND MOULD, METHOD AND DEVICE FOR CASTING METALS OF HIGH-MELTING TEMPERATURE UNDER LOW PRESSURE INTO A MULTI-STEP SAND MOULD Russian patent published in 1995 - IPC

Abstract RU 2044600 C1

FIELD: foundry engineering. SUBSTANCE: amount of square sections of feeders working in a ladle in every moment of casting exceeds square section of casting runner or at least is of the same value rate. It slows down metal flow over feeders and enables quiet filling of cavities. EFFECT: improved design. 7 cl
