INTRODUCTION

High carbon silicon is a novel composite alloy deoxidizer, which can replace the expensive traditional deoxidizer - ferrosilicon powder, calcium carbide, carbon powder and alloy powder. High carbon silicon has stable physical and chemical properties and good deoxidation effect. It can react with the oxygen in the molten steel quickly when added into the molten steel to form steel slag floating to the surface of the molten steel to achieve deoxidation.
