Calculation of silico-manganese alloy batching

The calculation of ingredients is generally carried out according to the following procedures and requirements. (1) Raw materials and product specifications: ①Determine the silico-manganese alloy production brand and composition; ②Determine the raw materials and composition, including raw materials such as manganese ore, coke, silica, flux and so on. (2) Parameter selection: ①Determination of element distribution coefficient, including alloying, slagging and volatilization loss; ②Selection of slag alkalinity; ③Coke loss coefficient, including furnace mouth burning loss and tapping carbon, generally 12% count. (3) Calculate based on 100 kg of manganese ore: ①Calculate the proportion of manganese ore, and calculate the mix ratio of mixed manganese ore into the furnace and the composition of the mixed manganese ore; ②calculate the amount of carbon required; ③calculate the amount of silica; ④add the amount of flux Calculation; ⑤ batch composition (kg), the quantity of manganese ore, coke, silica, flux and other raw materials in the batch is calculated from the above calculation; ⑥ alloy weight and composition calculation; ⑦ slag weight and composition calculation
