Production Introduction

        This product is divided into two series of MgO and MgO-SiO2. It doesn't contain harmful additives, such as sulphur, phosphorus, etc that may pollute the liquid steel. During construction, there is no need to add water. Thus it has the advantages of corrosion resistance, anti-scouring, clean liquid steel, long service life and easy for removal. The specific indexes can be adjusted according to the requirements of users.
