Anti-seepage castable
Application Industry: Refractories for Nonferrous Metal Industry
Application Equipment: Nonferrous Metal Electrolytic Cell, Rotary Kiln Kiln Mouth, Pre-tropical Zone, Calcination Zone, Cooling Machine, and Feed Nozzle
Size: Custom anti-seepage castable geometry per nonferrous metal electrolytic cell and rotary kiln design (free engineering on request)
Products Overview
Our Anti-seepage castable is a high-performance refractory product engineered for nonferrous metal electrolytic cell and rotary kiln service. The product family has the advantages of high strength, high wear resistance, anti-flaking and anti-scouring. It is suitable for rotary kiln kiln mouth, pre-tropical zone, calcination zone, cooling machine, feed nozzle and other parts. The product is suitable for calcination and roasting of cement, limestone, magnesia, ilmenite and non-ferrous metal ore. It has the advantages of strong acid and alkali corrosion resistance and good wear resistance and long service life.
The Anti-seepage castable product family is offered in one engineering-proven chemistry grade, the CH-TLD grade. The CH-TLD grade features Al2O3 content maximum 35% for nonferrous metal electrolytic cell and rotary kiln service, with Bulk Density minimum 2.1 g/cm3 after 110 °C curing for 24 hours, Cold Crushing Strength minimum 50 MPa after 110 °C curing for 24 hours and minimum 60 MPa after 1000 °C firing for 3 hours, Modulus of Rupture minimum 8 MPa after 110 °C curing for 24 hours and minimum 10 MPa after 1000 °C firing for 3 hours, and Thermal Conductivity maximum 0.5 W/m.k at 350 °C and maximum 0.7 W/m.k at 650 °C. The product reacts with electrolyte alkali metal ions in high temperature state to form a glaze layer on the surface of the material, preventing the penetration of the glass phase in the cement raw material, thereby playing an anti-skinning effect.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Anti-seepage castable grade is engineered to ASTM, GB/T, and ISO refractory standards.

Product Specification
In the high temperature state, the anti-crust castable forms a glaze layer on the surface of the material, preventing the penetration of the glass phase in the cement raw material, there by playing an anti-skinning effect. The material is mainly used for the easy skinning of the cyclone preheater cutting slope, rising flue, preheater cone and other parts.
