Refractory raw materials No matter how the technology develops, refractory raw materials are the basis of refractory materials. Refractory raw materials directly determine the quality of refractory materials and affect the development of refractory materials. All the development of new refractory materials cannot be separated from the support of refractory raw materials. For example, magnesia-alumina …

The tundish is a container for holding molten steel after the steelmaking ladle equipment and for diverting the molten steel for continuous casting. The tundish is the last container in the continuous casting system that contacts the refractory material before the molten steel is formed. It is an important part of the continuous casting process …
