Problems solved by technology

[0002] When aluminum alloy is smelted, due to the reaction between aluminum and water or oxygen in the air, harmful gases or solid particles will be produced. Such aluminum liquid will produce a series of quality problems such as pores, knives, and slag during deep processing and casting. Therefore, the refining and purification process must be carried out on the molten aluminum. The current commonly used method is the gas refining method, which takes out impurities by introducing an inert gas into the molten aluminum. This method consumes a lot of energy and has poor separation.

Abstract

The invention discloses a molten aluminum deslagging agent which comprises NaCl, KCl, Na2SiF6 and CaF2, wherein the weight ratio of the NaCl, the KCl, the Na2SiF6 and the CaF2 is 8:6:5:1. A preparation method for the molten aluminum deslagging agent comprises the following steps of adding the NaCl, the KCl, the Na2SiF6 and the CaF2 into a smelting furnace according to the ratio, melting and stirring the mixture, and preparing powder after the mixture is cooled. The molten aluminum deslagging agent has the advantages of high reliability, high separation capability, convenience in preparation, simplicity in use, low cost and the like, and is widely applied to the refining of molten aluminum.

Description

technical field [0001] The invention relates to the field of aluminum liquid refining, in particular to a liquid aluminum slag remover. Background technique [0002] When aluminum alloy is smelted, due to the reaction between aluminum and water or with oxygen in the air, harmful gas or solid particle impurities will be generated. Such molten aluminum will produce a series of quality problems such as pores, knife cutting, and slag in the later deep processing and casting. Therefore, it is necessary to carry out the refining and purification process for the molten aluminum. The gas refining method is commonly used at present. The impurities are brought out by introducing an inert gas into the molten aluminum. This method consumes a lot of energy and has a poor degree of separation. SUMMARY OF THE INVENTION [0003] The main technical problem solved by the present invention is to provide a liquid aluminum slag remover, which can ensure the infiltration effect of the aluminum ...
