Embodiment Construction

[0013] Crush the raw materials into the required specifications, then weigh 280 kg of silica, 160 kg of bauxite, 120 kg of barite, 120 kg of steel shavings, and 160 kg of coke. The 5000KVA submerged arc furnace is smelted. After the furnace is finished, the furnace eye is opened, and the silicon-aluminum-barium alloy liquid in the furnace is poured into the ingot mold. After cooling, the silicon-aluminum-barium alloy product is obtained. After testing, the composition of this product is Si42.12%, Al12.60%, Ba16.87%.

Abstract

The invention discloses a smelting silicon aluminum barium alloy preparation method, this method take the certain granularity silica, the bauxite, the barite, the steel filings and the coke as a raw material, after the certain ingredient compared to the mix, invests in the ore hot stove to carry on smelting, smelting temperature 1800-2500deg.C, the smelting time is in turn 2-3 hour is an end product. The method smelting silicon aluminum barium alloy output high, the electricity consumes lowly, economic efficiency considerable, the operation is simpler.

Description

technical field [0001] The invention belongs to the field of deoxidizer production in the metallurgical industry, and relates to a production method of a silicon-aluminum-barium alloy. Background technique [0002] Early silicon-aluminum-barium alloys were smelted in intermediate frequency furnaces using silicon-barium-iron alloys and pure aluminum as raw materials, and now there are also small submerged arc furnaces that use silica, bauxite, etc. as raw materials to smelt silicon Aluminum-barium alloy, but there are also phenomena such as high cost, low output, and serious energy waste. The inventor invented the method of producing silicon-aluminium-barium alloy on the 5000KVA submerged arc furnace just under this situation. Contents of the invention [0003] The purpose of the present invention is to provide a preparation method for smelting silicon-aluminum-barium-iron alloy on a 5000KVA submerged arc furnace, the production cost of this process is reduced, and the out...
