Discussion on the Problems of Aluminum Magnesium Castables
Nov 28 2020 · Aluminum Magnesium Castables are a general term for refractory castables with alumina and magnesia as the main components. Broadly called alumina-magnesia refractory castable generally referred to as alumina-magnesia castable. Application Range of Aluminum Magnesium Castables Synthesis method of magnesium aluminum spinel As the thermal expansion coefficient of magnesium aluminum spinel is small the thermal shock stability of refractory products using it as the binding phase is relatively high. In addition because spinel has good properties such as high hardness good chemical stability and high melting point it is very resistant to various melt erosion effects
