Abstract

The invention relates to a magnesium melt purifying device. The upper part of a crucible is provided with a crucible cover; thermoelectric couple is inserted into the crucible through a pore on the crucible cover; a protective gas input device, a flux quantitative feed device and a spiral blowing gas device are arranged on the crucible cover; a protective gas input tube is annularly arranged on the lower part of the crucible cover so as to ensure that protective gas is evenly scattered on the surface of the magnesium melt, thereby realizing effective protection of the magnesium melt; the fluxquantitative feed device mainly consists of a star shaped feeder so as to realize quantitative and even feed of the flux; and the spiral blowing gas device can be lifted up and down, after purifying treatment is completed, a spray head can be lifted to the upper part of the magnesium melt so as to reduce pollution on the magnesium melt. The magnesium melt purifying device has composite purifying function, can effectively remove impurities and harmful gases in the magnesium melt, greatly improve the quality of magnesium alloy, and is particularly applicable to purification treatment on the magnesium melt.

Description

technical field [0001] The invention relates to a metal melt purification device, in particular to a purification device specially used for magnesium melt, and belongs to the technical field of metal materials and metallurgy. Background technique [0002] my country is a big producer of magnesium resources and magnesium alloys, and the output of magnesium and magnesium alloy ingots accounts for more than half of the world's total output. At present, with the development of economy and society, magnesium and its alloys are receiving more and more attention due to their significant advantages such as low density, high specific strength and specific stiffness, and low raw material prices. Magnesium alloys have broad application prospects in the fields of automobiles, aerospace, military industry, and 3C products. However, most of the current magnesium alloys are used as non-structural parts. One of the key reasons is that the content of inclusions in the magnesium alloy is too...
