Abstract

The invention discloses a preparation method of a refining agent for melting an aluminum alloy section doped with plant ash. The refining agent is prepared from the following materials in parts by weight of 6-8 parts of potassium chloride, 4-6 parts of wood ash coated particles, 3-5 parts of calcium fluoride, 3-5 parts of sodium nitrate, 5-8 parts of graphite powder, 8-10 parts of sodium fluorosilicate, 3-5 parts of sodium sulfate, 5-8 parts of aluminum chloride, 3-5 parts of potassium carbonate, 8-10 parts of attapulgite, 5-8 parts of NaBF4, 3-5 parts of sodium chloride, 5-8 parts of potassium sulphate, 8-10 parts of Na2TiF6, and 5-8 parts of NaF. High-quality aluminum alloy melting liquid is obtained by treatment of the refining agent. Therefore, the aluminum alloy melting liquid is used for casting production; the yield is obviously improved; especially the porosity in a cast is reduced by 1-2 degrees; effective control is carried out; an air hole is not generated at the surface of the cast; trapped oxide is obviously reduced; and oxide inclusion is at about two grades while the mechanical property of the cast is obviously improved.

Description

technical field [0001] The invention relates to the field of smelting high-strength aluminum alloy profiles, and belongs to the technical field of aluminum alloy material processing. Background technique [0002] During the smelting process of aluminum alloy, it is necessary to use covering agent, slag removing agent, slag cleaning agent, refining agent, etc. The refining agent is added when the temperature of aluminum alloy reaches about 720 degrees. The refining agent used in the traditional aluminum alloy manufacturing process will cause the finished product The electrical conductivity, thermal conductivity, and corrosion resistance are not strong, and the porosity in the produced alloy castings is relatively high. There are many pores on the surface of the castings, and the proportion of oxide impurities is also high, which affects the performance of the alloy castings. Contents of the invention [0003] The object of the present invention is to provide a method for pr...
