Product Introduction

Magnesium carbon converter large surface repair material is aimed at the converter trunnion, large surface and the characteristics of the steel opening around the early damage, the product has less smoke, high bonding strength, high temperature fluidity, erosion resistance, erosion resistance and other characteristics, is the converter lining hot state maintenance of the ideal material. The product is rapidly softened and fluid at high temperature, put into use and after the furnace, the size of the converter surface to form a uniform distribution, to thicken the lining, and rapid sintering, so as to achieve the purpose of extending the service life of the lining.

The raw materials of the environmental-friendly water-based large-surface filling charge are: fused magnesia, nano-silica powder, high-temperature binding agent, burning aid, etc., with good flow performance, fast sintering, long service life, is a new type of environmental protection repair material.
