INTRODUCTION

Silicon barium inoculant is an inoculant for casting and deoxidizer for steelmaking. As an inoculant for casting, it can promote the formation of A-type graphite, refine eutectic clusters, improve the distribution of graphite, have strong anti fading ability, eliminate and prevent the white mouth tendency of castings, and reduce section sensitivity. When silicon barium inoculant is used as deoxidizer for steelmaking, it is smokeless, spark free, and has higher deoxidization effect than silicon calcium alloy, It can also improve the shape of non-metallic inclusions and improve the quality of steel.
