Abstract

The invention relates to a magnesium alloy fuel gas furnace, mainly providing high-quality magnesium alloy melts for cold room pressure casting and extrusion casting of the magnesium alloy. The invention develops a furnace body structure, which melts the magnesium alloy by using fuel gas as a fuel. The magnesium alloy fuel gas furnace mainly comprises a furnace body of a novel structure, a crucible, a heat exchanger, a burner, a furnace body bottom stop brick and a high temperature gas flow dividing device generated after burning. The magnesium alloy fuel gas furnace smelts the magnesium alloy by using cheaper fuel gas as energy instead of taking common electric heat as a heat source, the heat exchange performs extreme recovery on waste heat of the high temperature smoke, the energy saving effect is obvious, the use cost is lower, and more choices are provided for smelting, pressure casting, and the like of the magnesium alloy.

Description

Technical field [0001] The present invention relates to a magnesium alloy gas furnace, which mainly provides high-quality magnesium alloy bodies for magnesium alloy cold chamber die casting and squeeze casting, and belongs to the field of magnesium alloy melting. Background technique [0002] Currently commercially available magnesium alloy cold chamber die casting furnaces are mainly electric furnaces, most of which are resistance furnaces and some are electromagnetic induction furnaces. However, in some areas of my country, electricity resources are relatively tight and the cost is relatively expensive, while natural gas resources are relatively abundant and easy to obtain. Compared with electricity, the cost of using natural gas per unit of heat is lower. After theoretical calculation and practical use verification, the melting of the same weight The electricity cost of magnesium alloy is about twice that of natural gas. The current status of the above-mentioned electric furna...
