The Y-shaped components, elbows and closed valves in the tertiary air duct are seriously damaged, and the use conditions are the most harsh. The main damage of refractory materials in this place is the erosion wear and alkali sulfur chlorine erosion caused by high temperature gases containing alkali sulfur and chlorine carrying a large amount of dust, and the refractory materials are prone to wear, loosening and peeling.
Refractory materials for tertiary ducts include high-strength alkali-resistant bricks, high-strength alkali-resistant castables, wear-resistant castables, wear-resistant castable prefabricated parts, calcium silicate plates, diatomite bricks and lightweight castables. ZHENJIN REFRACTORIES' high-strength alkali-resistant bricks are made from low-alumina refractory clay. High temperature crystalline phases in their microstructure increase the chemical corrosion resistance and reduce the penetration and deposition of alkaline volatiles and detrimental components. It is used in preheating zones of CRK.
The refractory materials used in kiln door covers usually include low cement high aluminum refractory castables, mullite castables, high aluminum bricks, phosphate combined high aluminum bricks, silicate calcium plates, etc. ZHENJIN REFRACTORIES' high alumina castable are using modern technology of the ultrafine powder and low CA cement addition, high alumina castable have improved the middle-temperature strength and high-temperature stability. Low-cement, high alumina castable perform 2-3 times of service life to traditional castable. They have high density, high strength and low abrasion.
