INTRODUCTION

Remarkable benefits of recovering silicon manganese powder: Based on the principle of electromagnetic induction heating, the frequency conversion induction furnace is a remitting equipment that can directly heat metals, metal alloys and semiconductor materials. It is widely used in metal casting, diathermy, quenching and other mechanical processing industries. Low power consumption per ton, safe working environment, no pollution, good for environmental protection, considerable economic benefits, strong extensibility, the recovery rate of silicon manganese alloy reaches more than 93%, and the comprehensive unit consumption per ton is less than 1350Kw H/t, the average life of furnace lining shall not be less than 400 heats. It effectively solves the secondary recycling of silicon manganese powder, which has strong promotion value and significance in the ferroalloy industry.
