Special Castable for Kiln Hood & Coal Injection Pipe
This high-performance castable is manufactured from premium corundum and electrofused mullite, enhanced with composite ultra-fine powders and modified additives. It exhibits exceptional thermal shock stability, chemical erosion resistance, low creep rate, minimal thermal expansion, and outstanding wear resistance. The modified additives form a protective film at elevated temperatures, effectively sealing pore channels to further improve erosion and wear resistance. Simultaneously, the additives undergo thermal decomposition to form mullite, generating micro-expansion that counteracts shrinkage under high-temperature conditions, thereby significantly enhancing the castable's thermal shock stability.

This product is tailor-made for key skinning-prone parts of cement kilns, such as the smoke chamber and decomposition furnace. Made from silicon carbide raw materials, it boasts excellent anti-skinning and wear-resistant properties, which can inhibit the formation of skinning from the source. Moreover, the formed skin has weak adhesion and is easy to clean. At high temperatures, the material forms a self-protective vitreous layer with a stable structure, significantly reducing downtime.

Silicon Carbide Anti-coating Castable
Silicon carbide anti-skinning refractory castable is a high-performance castable primarily composed of silicon carbide, supplemented with high-efficiency water reducers and ultra-fine powder, and bound with calcium aluminate cement. It significantly reduces the frequency of skinning. This castable boasts excellent wear resistance, high strength, non-reactivity with materials, and anti-skinning properties. Silicon carbide exhibits good wear and corrosion resistance, high strength at high temperatures, high thermal conductivity, low linear expansion coefficient, good thermal shock resistance, and no reactivity with cement raw materials. The castable forms a glazed protective layer at high temperatures, preventing skinning and ringing. It is primarily used in cement kiln decomposing furnace cones, kiln tail gas chambers, preheater cones, and other applications.

High-Strength Alkali-Resistant Castable
High-strength alkali-resistant refractory castable is made from aluminum silicate and high-pressure electric porcelain as refractory aggregates and powders, formulated with aluminate cement and additives. It is a high-quality castable that can effectively resist the erosion of alkali metal oxides at high temperatures. At high temperatures, it reacts with alkali metal oxides to produce a high-viscosity liquid phase, forming a glazed protective layer. It has the characteristics of stable chemical composition, good fluidity, high strength, and strong erosion resistance. It is mainly used in the preheater system of cement kilns.

High Alumina Low Cement Castable/High Alumina High Strength Castable
High-alumina low-cement castable adopts high-quality bauxite and ultrafine powder technology, which significantly improves the medium-temperature strength and high-temperature volume stability. The firm crystalline structure formed at high temperatures endows the product with excellent properties such as high strength, wear resistance and thermal shock resistance. Its service life is 2 to 3 times longer than that of traditional products, and it is widely applied to key parts of cement kilns including kiln hoods and grate coolers.

Steel Fiber Reinforced Castable
Steel fiber reinforced castable is made from high-quality high-alumina clinker and corundum as main raw materials, aluminate cement as binder, with micro-powder and stainless steel fiber added. It features excellent high-temperature resistance, wear resistance, good thermal shock resistance and structural integrity.The addition of heat-resistant stainless steel fibers forms a network structure inside the castable and optimizes its internal stress distribution. While maintaining the original high-temperature performance, it improves the toughness, mechanical vibration and impact resistance, and wear resistance of the cast body, thus extending its service life.It is mainly used for the kiln mouth, kiln head hood, tertiary air duct, grate cooler and other parts of cement kilns.
