APPARATUS FOR CASTINGS DIRECTED HARDENING Russian patent published in 1996 - IPC

FIELD: metallurgy, casting production used in process of pattern ingots casting in mechanical engineering. SUBSTANCE: aim is to increase output of commercial casting. To realize the aim apparatus has casting mould, crucible mounted in smelting furnace inductor with inner partition dividing crucible cavity for smelting cavity and through cavity, in which casting mould is located on tray-cooler mounted on rod of lifting and lowering mechanism and made on upper part of crucible outer wall discharge chute with operational surface located at angle of Φ to horizon. Part of crucible bottom adjacent to inner partition is made inclined at angle of v to horizon. In the case surface of the inclined part of crucible is located at level of plane tangential to operational surface of bottom of discharge chute or over it. Pouring gate funnel of casting mould has pouring off nose made from side opposite to discharge chute. End of nose is located above crucible inner partition, on top of which lid is located. EFFECT: increased output of commercial casting. 1 dwg
