Abstract

The invention discloses rear-earth magnesium alloy smelting agent and a preparation method thereof. The rear-earth magnesium alloy smelting agent comprises the components in a molar ratio of chlorate to trifluoromethyl sulfonate to carbonate equal of (80-90):(1-3):15; the mixed solution is sprayed in to solution drops through a spraying device; the solution drops directly enters a decompression flashing device for evaporating and dehydrating; primary gas-solid separation is carried out by a gas-solid separating device; solid-phase materials are fed to a fluidization drying device, so that fluidization drying is carried out onto the solid-phase materials by the air which is pre-heated to 120 DEG C to 200 DEG C; secondary gas-solid separation is carried out by the gas-solid separating device to control the moisture content of the solid-phase materials to be within 0.2%; and the solid materials is filled in a sealed container for storage and used rear-earth magnesium alloy smelting agent for future use. The rear-earth magnesium alloy smelting agent is environment-friendly and energy-saving, low in treatment cost, good in treatment effect and high in utilization rate of valuable constituents.

Description

technical field [0001] The invention relates to a rare earth magnesium alloy, in particular to a rare earth magnesium alloy melting agent. The invention also relates to a preparation method of the rare earth magnesium alloy melting agent. Background technique [0002] Since the late 1980s, with the application of magnesium alloys in the field of aviation and aerospace, the research on the application of rare earth elements to magnesium alloys has been re-emphasized. Rare earth magnesium alloys can overcome the shortcomings of traditional magnesium alloy materials and meet the requirements of modern industry. Requirements for materials such as lightweight, energy saving, environmental protection, safety, comfort, and sustainable development. As the main alloying elements or microalloying elements, rare earths are playing an increasingly important role in the research field of magnesium alloys. Rare earth magnesium alloy is currently the lightest metal structural material in...
