There are obvious differences between chrome corundum castable and corundum castable in terms of composition, performance and application fields.
Composition: Chrome corundum castable is a composite castable made of corundum and chromium, while corundum castable mainly contains alumina and silicon oxide.
Performance: Chrome corundum castable has the advantages of high density, good organizational structure, low creep rate, small thermal expansion, good thermal shock resistance, and strong erosion resistance. Corundum castable has good strength, high aluminum content, high temperature resistance, and can also be made into composite materials with mullite and silicon carbide materials.
Application field: Chrome corundum castable is usually used in severe erosion conditions and test furnaces with temperatures exceeding 1700℃. Corundum castable is more commonly used in high temperature environments of furnace linings exceeding 1500℃, and has a long service life.
In general, chrome corundum castables and corundum castables are both refractory materials, but they differ in composition, performance and application areas. The choice of which material to use mainly depends on the specific process requirements and application scenarios.
