DEVICE FOR CHANNELLED HARDENING OF INGOTS Russian patent published in 1995 - IPC

FIELD: foundry engineering. SUBSTANCE: device has a mould, a crucible, a pouring spout. Crucible is set up in an induction coil of a smelting furnace and has an inner membrane which devices the crucible space into a smelting hollow and a through hollow where a stool-cooler mounted mould is placed. Stool-cooler is fixed on a draw-spike rod. Pouring spout working surface has a slope of ϕ to horizon. The part of crucible bottom touching the inner membrane is positioned at an angle to horizon on the level of a plane tangent to the working surface of pouring spout or above it. The upper part of the crucible through hollow has the shape of a funnel. Heating plug is mounted within this funnel. A pouring channel is constructed within heating plug to connect the smelting hollow with the pouring spout positioned on funnel surface. EFFECT: improved design. 2 dwg
