INTRODUCTION

Si-C alloy is a new type of alloy used in converter. It is generally called silicon carbon alloy or high carbon silicon. It can replace ferrosilicon, silicon carbide and carburetor, reduce the amount of deoxidizer, and be used in the deoxidization and alloying process of converter smelting. The effect is stable, and the chemical composition, mechanical properties and internal control quality of steel are superior to the traditional process. Its characteristics: improve the quality of molten steel, improve product quality, improve new energy of products, reduce alloy addition, reduce steelmaking costs, and increase economic benefits.
