APPARATUS FOR 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 crucible mounted in inductor of smelting furnace and provided with inner partition dividing crucible cavity for smelting cavity and through cavity; casting mould on tray-cooler mounted on rod of lifting and lowering mechanism; made on upper part of crucible outer wall discharge chute with operational surface located at angle 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. Lower part of through cavity is made in the form of truncated cone, upper base of which is located above lower coil of inductor, and lower base coincides with pouring gate funnel of casting mould; on the side opposite to discharging chute in through cavity beginning from upper base of truncated cone there is carrying off chute; upper surface of casting mould coincides with lower surface of crucible lining; lid is located on top of crucible. EFFECT: increased output of commercial casting. 2 dwg
