Magnesium alloy melting pool type crucible electrical resistance furnace

Abstract

The utility model relates to a molten-pool pot resistance furnace of magnesium alloy, comprising heating modules of which two heating modules which are positioned up and down respectively on the innerwall of the furnace body are formed into a group; wherein, a group of two lateral face heating modules are positioned up and down on the left and the right inner wall of the furnace body which are corresponding to the front end and the back end of the pool-type pot; and two or more groups of frontal heating modules which are corresponding to the position of two or more chambers in the pool-type pot are positioned respectively on the front and the back inner wall of the furnace body which are corresponding to two side ends of the pool-type pot. The pool-type pot is divided into three temperature regions of temperature region I, temperature region II, and temperature region III when the pool-type pot is seen from the front; wherein, an up temperature region and a down temperature region form a subarea, thus forming synchronous heating regions which are mutually independent to maintain the flow of continuous and high-quality melts and satisfy the refined thermodynamic and dynamic conditions of the melts via precisely regulating the crafting parameters.

AI Technical Summary

Problems solved by technology

The solubility of these refractory impurities in magnesium alloy is small, the melting point is also high, and the specific gravity is larger than that of magnesium. Although this method can remove the fusible impurities in the alloy, it does not rule out the secondary pollution of the melt, which is more important. The disadvantage is that the adsorption and precipitation of inclusions takes a long time, and the solvent refining method cannot effectively degas, and at the same time, it leads to difficulty in gas protection, large consumption, cumbersome process steps, and greatly reduces production efficiency.
