Abstract

The invention discloses a casting and smelting additive which is prepared from the raw materials including 10-15 parts of sodium oxide, 3.5-8.5 parts of aluminum oxide, 3.5-8.5 parts of potassium oxide, 6-11 parts of sodium carbonate, 3-9 parts of silicon dioxide, 11-18 parts of calcium oxide, 1.5-8.5 parts of iron oxide, 0.5-2 parts of titanium dioxide, 3.1-5.5 parts of olefinic thermoplastic elastomer, 1.2-3.3 parts of dysprosium oxide and 5-10 parts of anhydrous sodium borate. The additive has the advantages of low cost, no toxin, no harmful ingredient and no environmental pollution; because the liquidity of molten steel can be increased during smelting, the air pores and the slag eyes of finished casts can be reduced, the compression strength and the tensile strength of the casts can be increased, and thus, the finished cast rate is increased from 90% to 98%; the bridging phenomenon of a poured material can be avoided during smelting; residues can not be stuck to the furnace wall during smelting, the service life of the furnace body can be prolonged by 20%, the smelting time can be shortened by 1 / 3, the power consumption can be greatly saved, and the enterprise revenue can be increased.

Description

technical field [0001] The invention relates to auxiliary materials for smelting and casting, in particular to a casting and smelting additive that can rapidly increase the smelting speed. Background technique [0002] In the metallurgical smelting and foundry industry, the melting speed of various types of electric furnaces (such as high-frequency, intermediate-frequency or electric arc furnaces, etc.) serious pollution. Contents of the invention [0003] The object of the present invention is to provide a casting smelting additive which can increase the smelting speed, save energy and reduce waste discharge. [0004] To achieve the above object, the present invention can take the following technical solutions: [0005] Casting smelting additive of the present invention, it is made of raw material sodium oxide (Na 2 O), alumina (Al 2 o 3 ), potassium oxide (K 2 O), sodium carbonate (NaCO 3 ), silicon dioxide (SiO 2 ), calcium oxide (CaO), iron oxide (Fe 2 o 3 ),...
