Problems solved by technology

The flux commonly used now is mainly composed of anhydrous carnallite (MgCl2-KCl) and some fluorides and chlorides. The flux must be remelted and dehydrated before use. Choking smell, polluting the environment, severe corrosion of the factory building, and many occupational diseases in the respiratory tract of the operator. In addition, the flux has low slagging ability and poor separation from the magnesium melt, so it is easy to be wrapped in the magnesium melt to form flux inclusions

Abstract

The invention provides magnesium alloy smelting protection solvent and a preparation method thereof. The magnesium alloy smelting protection solvent comprises the following chemical components in parts by weight: 8-15 parts of barium carbonate, 12-15 parts of calcium sulfate, 12-17 parts of nanometer zirconium oxide, 12-15 parts of magnesium chloride, 12-20 parts of hydroxyapatite, 12-20 parts of magnesium silicate, and 1-5 parts of lithium chloride. The preparation method is to perform the mixing after the drying. The smelting protection solvent, provided by the invention, is molten to a liquid state in an environment of higher than 500 DEG C in the smelting process, and is spread on the surface of an alloy or molten magnesium to achieve an air isolating effect and to stop the magnesium oxidation so as to obtain excellent protection performance.

Description

technical field [0001] The invention belongs to the field of magnesium alloy production, and in particular relates to a protective solvent for magnesium alloy smelting and a preparation method thereof. Background technique [0002] As the lightest engineering metal structure material, magnesium alloy has the advantages of light specific gravity, high specific strength and specific stiffness, good damping and machinability, good thermal conductivity, strong electromagnetic shielding ability, good vibration damping and easy recycling. Aviation, aerospace, and modern automobile industries have requirements for weight reduction and energy saving, and can replace engineering plastics to meet the requirements of lightness, thinness, miniaturization, high integration, and environmental protection of 3C (computers, communications, and consumer electronics) products. It has become the material of choice for modern automobiles and 3C industries, and is known as "the green engineering ...
