Metal liquid degassing and deslagging device

Abstract

The invention discloses a metal liquid degassing and deslagging device. The device comprises a material discharging unit, a tank locking component, a slurry storage device, a rotating component, a material conveying component and a base; the rotating component is composed of a motor, gears, a rotating shaft and a rotating disc, wherein the rotation of the motor drives the rotating disc to rotate at a high speed through gear transmission; the tank locking device is composed of hydraulic cylinders and connecting rods, the hydraulic cylinders are connected with material storage tank lug rings through the connecting rods, the angle of material storage tanks is adjusted through extending and retracting of the hydraulic cylinders so that various machining states can be realized; and the slurry storage device is formed by machining a stainless steel pipe, a heating hole is formed in the pipe wall, a heating element is arranged in the heating hole, and the bottom of the heating element is matched with concave pistons and the hydraulic cylinders. According to the device, redundant air and impurities in the metal liquid can be effectively removed, automatic deslagging can be achieved, occurrence of safety accidents can be effectively avoided, and the quality of the metal liquid is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of casting, and relates to a device for removing impurities in liquid metal, in particular to a device for removing impurity gas in liquid metal. Background technique [0002] Die-casting machine is a common equipment in the field of forming technology in the machinery industry. It is an industrial machine that hydraulically injects molten metal into a die-casting mold for cooling and forming under pressure, and obtains solid metal castings after the mold is opened. In die casting production, the quality of metal liquid is the key, which directly affects the molding quality and internal microstructure of die castings, and determines its mechanical properties to a large extent. The production method commonly used in existing factories is to first heat the metal ingot above the liquidus line in the furnace and melt it into a molten metal, and then add a slag remover to make the impurity particles sink under th...

AI Technical Summary

Problems solved by technology

For metal liquids with high viscosity or when the temperature of the metal liquid is low, it is difficult for the impurity particles to form a sedimentation process only under the action of the gravity field, the slag removal effect is not obvious, and the quality and internal microstructure of the formed castings are not ideal, which cannot meet the actual conditions. need
