The ladle is responsible for the dual tasks of carrying molten steel and refining outside the furnace. With the development of steelmaking technology, my country’s ladle refractory materials have also been well developed. Especially since the 1980s, my country’s refractory research institutions, production enterprises and users have worked closely together to develop new refractory materials …

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 …

Quartz sand is an acidic furnace lining material, due to the low price and wide range of sources. Once the silica sand after the first furnace high-temperature sintering to complete its phase change, volume expansion changes, the late melting of the furnace lining volume change is very small, thermal stability and anti-ferrous liquid leakage performance …

Aluminum carbon bricks are mainly composite refractory materials produced by combining alumina (such as sintered/fused white corundum, sub-white corundum, brown corundum, plate-shaped alumina, sintered bauxite, etc.) and carbon/graphite raw materials. In most cases, additives (such as SiC, Si, Al, etc.) are also added to improve their performance. According to the production method, Al2O3-C refractories can …
