Vacuum induction smelting furnance

Abstract

The invention discloses a vacuum induction melting furnace, which relates to a crucible furnace that is suitable for charging treatment in vacuum or special atmosphere. The invention provides an improved vacuum induction melting furnace with better casting cooling effect and good productivity, which comprises a vacuum melting chamber, a medium frequency coil furnace, a set of vacuum pump and a corresponding vacuum pipeline system, a electric control system, a medium frequency power supply system, a hydraulic cylinder control system, a cooling system, and a pit discharging system. The cooling system is provided with a tundish feed divider, a belt wheel cooling mechanism, a baffle cooling mechanism and a turning wheel cooling mechanism. The pit discharging system comprises a medial chamber box, an inner container, an outer container, a walking car, a hydraulic lifting cylinder, a pit track, a flap valve and a guide shell. The guide shell and the flap valve are arranged in the medial chamber box, the outer container is fixedly arranged on the walking car, and the inner container is sheathed at the inner wall of the outer container.
