Abstract

The invention discloses an aluminum or aluminum alloy melt slag removal agent and belongs to the technical field of metal liquid impurity removal. The aluminum or aluminum alloy melt slag removal agent comprises the following component formulas in percentage by weight: 25-30 percent of sodium chloride, 25-30 percent of potassium chloride, 5-10 percent of sodium carbonate, 5-10 percent of sodium sulfate, 1-5 percent of sodium fluoroaluminate, 5-10 percent of sodium fluosilicate, 5-10 percent of calcium fluoride, 1-5 percent of potassium nitrate and 5-10 percent of potassium fluosilicate. The aluminum or aluminum alloy melt slag removal agent is high in heating property, the aluminum in the slag can be fully separated, the alumina components are decomposed, and the aluminum consumption is reduced, so that the aluminum slag is dry and loose and is easily removed; the treated aluminum liquid purity is greatly improved, and the metal performance is improved; and moreover, the slag attached to the furnace wall and the furnace hearth is reduced, the furnace body is damaged, the service life of the smelting furnace is prolonged, and the prepurging cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of removing impurities from molten metal, and in particular relates to an aluminum or aluminum alloy molten slag remover. 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 purpose of the present invention is to solve the problems of metal loss and inclusion of oxidized metal film in the refining process of aluminum or aluminum alloy, and provide an aluminum or aluminum alloy molten slag cleaning agent that can separate...
