Abstract

The invention relates to a novel flux for ZK60 magnesium alloy, and a preparation method and a usage method thereof, and belongs to the smelting field. The novel flux is characterized by comprising the following raw materials, by weight: 30-40% of MgCl2, 35-45% of KCl, 5-8% of CaF2, 2-5% of CaCl2, 18-20% of BaCl2, and 4-5% of ZrCl4. The novel flux provided by the invention enables the yield of the Zr element in the magnesium alloy increases to 70-75%, so as to effectively control smelting cost and save the zirconium resource, and has a breakthrough significance in the research of the field.

Description

technical field [0001] The invention relates to a novel flux for a ZK60 type magnesium alloy, a preparation method and a use method thereof, and belongs to the field of alloy smelting. Background technique [0002] Mg-Zn alloys are prone to grain growth, which reduces the strength of the alloy and increases its brittleness. Zr element can effectively refine grains, and is the most effective grain refinement element for as-cast Mg-Zn alloys, and thus Mg-Zn-Zr alloys are developed. At present, the most widely used Mg-Zn-Zr alloy in the world is ZK60A, which is the alloy with the highest strength, the best comprehensive performance and the most widely used among industrial deformed magnesium alloys. [0003] When ZK60 is smelted, the traditionally used RJ-5 flux is used as the refining flux, and the yield of zirconium is only 20-35%. As a rare metal, the price of zirconium is also rising with the gradual consumption of resources, making this The cost of this alloy is getting ...
