AI Technical Summary
Traditional refractory materials in RH refining furnaces cannot simultaneously achieve excellent corrosion resistance and erosion resistance, which leads to easy damage to the surface structure of the material and a shortened service life.
MgAlON-oxide composite refractory materials are used, with functional nano-silica and aluminum phosphate as sintering aids, and calcium fluoride and lanthanum oxide as functional aids. Combined with a gradient sintering process, a coating layer and a continuous network structure are formed, which improves the density and grain boundary bonding strength of the material.
It significantly improves the mechanical properties, high-temperature resistance and chemical stability of the material, enhances its wear resistance and resistance to slag penetration, and extends its service life.
