Specification of Moulded Alumina Refractory Castable Clay for Cement Kilns Tabular Primarily Mullite Corundum Bauxite MgO SiO2 Welding Powder

This moulded alumina refractory castable clay is made for cement kilns. It lasts a long time under tough conditions. The main ingredients are high-purity tabular alumina and mullite. Corundum and bauxite are also key parts. This mix gives excellent heat resistance and strength. MgO and SiO2 levels are carefully balanced. This balance controls how the castable performs. It helps with slag resistance and prevents cracking. Welding powder is added too. This powder makes installation easier and faster. It bonds the material quickly during repair work.

The castable is very dense and strong. It handles temperatures over 1700°C. Thermal shock resistance is very good. This means it survives rapid heating and cooling cycles. Chemical resistance is strong against alkalis and other kiln materials. Abrasion resistance is high. This protects it from flying clinker and dust. Installation is simple. You just add water and mix. Then you pour it or vibrate it into place. It sets fast and hardens quickly. This reduces kiln downtime during repairs.

This material works best in high-wear cement kiln areas. Use it in the burning zone. Use it in the transition zone. Use it in the upper cyclone area. It is good for patching damaged linings. It is also good for building new linings. It bonds well with old refractory bricks and castables. The properties make it reliable. It keeps the kiln running longer between shutdowns. This saves money on maintenance. Production time increases.

Applications of Moulded Alumina Refractory Castable Clay for Cement Kilns Tabular Primarily Mullite Corundum Bauxite MgO SiO2 Welding Powder

Moulded alumina refractory castable clay offers a strong solution for cement kilns. This material handles extreme heat and chemical attack well. It lasts a long time. The main ingredient is high-purity tabular alumina. Tabular alumina provides excellent volume stability and strength at high temperatures. It resists wear effectively.

Other key materials are also included. Calcined bauxite adds alumina content. This boosts overall refractoriness. Mullite forms naturally within the castable during heating. Mullite enhances thermal shock resistance. It also improves structural integrity. Fine corundum particles fill gaps. This creates a very dense structure. Density is crucial for resisting slag and chemical penetration.

Specific additives play important roles. Magnesia (MgO) helps control reactions with cement kiln clinker. Silica (SiO2) is carefully managed. Too much silica lowers the melting point. This is bad. Very fine powders act like welding powder. They bond everything together tightly during sintering. This creates a strong, unified structure.

Cement kilns present tough conditions. This castable works well in critical zones. It lines the burning zone effectively. It withstands the highest temperatures there. The material also protects the transition zone. Temperature changes happen fast there. The castable copes with these changes. It serves well in the lower cyclone stages. Abrasion and dust erosion happen there. The castable fights this wear. Its chemical resistance is vital. It stops clinker liquid slag from damaging the kiln lining. This saves money on repairs and downtime.

5 FAQs of Moulded Alumina Refractory Castable Clay for Cement Kilns Tabular Primarily Mullite Corundum Bauxite MgO SiO2 Welding Powder

What is this castable clay for?
This moulded alumina refractory castable clay is made for cement kilns. It builds or repairs the hot lining inside the kiln. It handles extreme heat and chemical wear during cement making.

What materials are inside?
The main stuff is high-purity bauxite. This gives alumina. Then there’s tabular alumina, mullite, and corundum. These are super hard and heat resistant. We also add specific amounts of MgO and SiO2. These help it set strong and stick well. Special welding powder makes it easy to install.

Why choose this castable over others?
It lasts longer in the harsh cement kiln environment. The mix of bauxite, tabular alumina, mullite, and corundum fights heat and chemical damage very well. The MgO and SiO2 help it form a strong bond. The welding powder makes application smoother.

How do you install it?
Mix the dry powder with clean water. Follow the exact water amount on the bag. Mix it thoroughly until it’s consistent and sticky. Then cast or mould it into place quickly. Let it set and dry properly before heating the kiln. Follow the heating schedule strictly.

How well does it perform?
It performs extremely well under high heat and chemical attack. The dense structure from the fine materials stops slag and hot gases from eating into the lining. This means less downtime for repairs. It lasts longer than many other castables in cement kilns.
