Through improving the hearth activity, optimizing the control of slag alkalinity, developing control technology for liquid iron level in hearth, developing burden distribution matrix of shifting of ore and coke and accurate control technology of burden distribution by time method, the problems arisen in low silicon production and under the raw material conditions of 430 kg/t slag ratio and 135 kg/t into the furnace silicon load, such as poor iron slag discharge, unstable gas utilization and large fluctuation of the furnace temperature were solved. The monthly average silicon content in pig iron was decreased from 0.47% to 0.37%. The one class rate was increased from 43.67% to 86.22%, gaining better the index of technology and economy.
