Smoke-free and sodium-free slag removing agent and preparation method thereof

Abstract

The invention discloses a smoke-free and sodium-free slag removing agent in the technical field of slag removing agents. A formula of the smoke-free and sodium-free slag removing agent comprises 5-15parts of potassium sulfate, 7-13 parts of potassium carbonate, 5-10 parts of potassium fluoroaluminate, 10-20 parts of potassium fluosilicate, 20-30 parts of potassium chloride, 15-25 parts of potassium fluoride, 3-5 parts of potassium nitrate, 4-8 parts of calcium fluoride, 9-15 parts of magnesium fluoride, 7-11 parts of aluminum fluoride, 3-7 parts of calcium chloride, 2-6 parts of barium sulfate, 2-4 parts of titanium oxide, 2-6 parts of rare earth, 1-5 parts of barium chloride, 7-9 parts of ethyl acetate, 2-4 parts of barium fluoride, 5-7 parts of potassium fluotitanate and 3-5 parts of magnesium chloride. A preparation method of the smoke-free and sodium-free slag removing agent comprises the specific steps as follows: S1, raw material proportioning; S2, raw material baking; S3, mixing and heating, S4, smoke dust treatment; S5, smog treatment; S6, crushing and granulation; S7, weighing and packaging; S8 classification and storage. The produced smoke-free and sodium-free slag removing agent contains no sodium elements, so that finished products of aluminum and aluminum alloys cannot contain a large quantity of sodium elements.

Description

technical field [0001] The invention relates to the technical field of slag remover, in particular to a smokeless and sodium-free slag remover and a preparation method thereof. Background technique [0002] Aluminum and aluminum alloys will inevitably oxidize and absorb gas during the smelting process and produce aluminum slag. If it cannot be effectively removed during the smelting process, it will cause defects such as slag inclusions and pores, which will directly affect the quality of the final product. It is a more effective method to add slag cleaning agent in the process of removing aluminum slag, but most of the slag cleaning agents now contain a large amount of sodium element, because the added slag cleaning agent contains too much sodium element, which will cause smelting Aluminum and aluminum alloy products contain a large amount of sodium element. When the sodium element content is too high, sodium embrittlement will occur, which will reduce the structural streng...

Problems solved by technology

[0003] The object of the present invention is to provide a smokeless and sodium-free slag remover and preparation method thereof, to solve the problem that most of the present slag removers proposed in the above-mentioned background technology contain a large amount of sodium elements, because the added slag remover contains too much The sodium element will cause the smelted aluminum and aluminum alloy products to contain a large amount of sodium element. When the sodium element content is too high, sodium embrittlement will occur, which will reduce the structural strength of the smelted aluminum and aluminum alloy products, thereby reducing the aluminum alloy. and the quality of aluminum alloy finished products, adding slag remover at the same time will produce a lot of smoke and pungent smell, which will increase the loss rate of metal, and will also threaten the health of operators and require a large amount of slag remover, which will make production The problem of cost increase
