Abstract

A molten aluminum alloy refining slag removal agent is characterized by being composed of, by weight, 25%-30% of silicon dioxide, 10%-15% of sodium chloride, 10%-15% of potassium oxide, 5%-10% of sodium oxide, 5%-10% of sodium sulfate, 1%-5% of sodium fluoroaluminate, 5%-10% of sodium fluorosilicate, 1%-5% of titanium dioxide, 5%-10% of calcium fluoride, 2%-4% of potassium fluoride, 2%-4% of hydrogen fluoride and 2%-4% of silicic acid. The molten aluminum alloy refining slag removal agent has the advantages that by the adoption of the sodium chloride and the potassium fluoride, the infiltration effect of molten aluminum is guaranteed, separation of hydrogen in the molten aluminum is guaranteed by the adoption of the potassium fluoride, the molten aluminum alloy refining slag removal agentis high in reliability, high in separation capacity, convenient to prepare, easy to use, low in cost and the like, and meanwhile the molten aluminum alloy refining slag removal agent can be widely applied to the molten aluminum refining aspect.

Description

technical field [0001] The invention relates to the technical field of slag remover, in particular to a slag remover for aluminum alloy melt refining. Background technique [0002] If there are impurities in aluminum or aluminum alloy that will affect the properties of the metal, it is generally necessary to remove impurities as much as possible through refining. During the refining process, aluminum is contained in the separated aluminum slag, which causes the loss of aluminum metal; at the same time, an aluminum oxide film is produced due to oxidation, and aluminum oxide is easily mixed in the aluminum metal liquid, affecting the metal performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an aluminum alloy molten slag cleaning agent capable of separating aluminum from aluminum slag and decomposing alumina. [0004] In order to solve the above technical problems, the technical solution provided by the pr...
