Product Introduction

Electric furnace cover and refining furnace cover are based on the conditions that furnace cover materials are frequently subjected to thermal shock, erosion of steel slag and CO, CO₂ and SO gas in the furnace, radiation of high-temperature arc light, airflow wear formed by high-speed dust extraction in the furnace, etc. According to the different use and operation conditions of various electric furnaces and refining furnaces, the formula is scientifically formulated, the particle size composition is precisely mixed, and cement or cement is selected, it is formulated with ultra-fine powder technology and excellent binder admixture. It has the characteristics of good thermal shock stability, erosion resistance, good volume stability and long life. It is suitable for ordinary electric furnace, ultra-high power electric furnace, refining furnace and VD furnace.
