INTRODUCTION

Metal silicon ball is a deoxidizer for steelmaking with good effect, high product utilization rate and low cost. As a new type of deoxidizer for steelmaking, metal silicon spheres can meet the deoxidization needs of different steel grades, reduce the consumption of strong deoxidizers such as silicon calcium barium and silicon aluminum calcium barium, reduce the production cost of steel by about 2. 0 yuan/ton, and increase the yield of alloy elements by more than 1. 5%. The composition fluctuation is small. The metal silicon spheres not only reduce the cost, but also reduce the pollution to the environment.
