INTRODUCTION

Rare earth ferrosilicon is massive, metallic luster, hard and brittle, and easy to crush. The rare earth ferrosilicon alloy is silver gray. Rare earth ferrosilicon magnesium alloy has blue luster in silver gray matrix.

Moderate rare earth silicon iron modification treatment significantly improves the impact toughness and wear resistance of high chromium white cast iron, and the maximum improvement will be achieved. The optimal addition amount of rare earth ferrosilicon is about 0.8-1.0%, exceeding this amount will lead to a decrease in impact toughness and wear resistance
