Abstract

The invention relates to a heat-preserving furnace for magnesium alloy die casting. The furnace comprises a heat-preserving furnace body. A first crucible is arranged in the heat-preserving furnace body. The heat-preserving furnace for magnesium alloy die casting further comprises an electric heating furnace, a second crucible is arranged in the electric heating furnace, and the first crucible and the second crucible are communicated through a siphon pipe. The heat-preserving furnace utilizes the siphon principle to keep liquid level and temperature constant and greatly improves quality of magnesium alloy die casting pieces in an allowable range.

Description

technical field [0001] The invention relates to an industrial furnace, in particular to a holding furnace for magnesium alloy die-casting. Background technique [0002] At present, the holding furnace for magnesium alloy die-casting is an electric heating furnace, which is composed of furnace wall, insulation material, electric heating wire, temperature measurement and control system, etc. The furnace is equipped with a crucible to hold the magnesium alloy liquid. The holding furnace for magnesium alloy die-casting is generally used as the side furnace of the magnesium alloy die-casting machine. The holding furnace transfers the magnesium alloy liquid into the barrel of the die-casting machine. The methods of transferring include artificial spoon, mechanical pump, pneumatic pump, plunger pump, etc. , no matter what die-casting casting method is used, maintaining a constant liquid level and temperature in the furnace is the premise to ensure casting accuracy. [0003] In the...
