Title:
PROCESS FOR PRODUCING RHEOCAST INGOT PARTICULARLY FOR PRODUCTION OF HIGH-MECHANICAL-PERFORMANCE DIE CASTING
Document Type and Number:
Japanese Patent JP3188352
Kind Code:
B2
Abstract:
PURPOSE: To provide a process for producing semiliquid casting ingots for opti mum production of high-mechanical-performance die castings.
CONSTITUTION: A metal alloy having a pig form and containing or not containing ceramic particles is smelted in a smelting furnace, transferred to a ladle, degassed, and fed into a pressurized furnace 6, from which the alloy is case in the semiliquid state by feeding the alloy to the solidification state and under laminar flow conditions into a static mixer 12. At the outlet of the static mixer 12, the rheocast material is collected after passing a metallic die 20 under laminar flow conditions. The system is provided with the interposition of a siphon type collecting tank 14 and with protective gas shielding, and the material is solidified into a single billet. The billet is then guided by rollers 25 past a saw 26 and cut into pieces, from which to obtain ingots of desired weight and size.
