Refractory materials

Refractory materials for blast furnace Refractory materials for blast furnace masonry provide a basic guarantee for the modernization of blast furnaces. The blast furnace body structure (furnace wall) is composed of three parts: the furnace shell, the cooler and the refractory lining. The main function of the inner lining is to directly resist mechanical, thermal…
