Material Type
Steel fiber reinforced refractory castable is used to construct the linings of industrial kilns that come into contact with high-temperature gases or solid materials. This is because, in situations of intermittent use, there are significant temperature fluctuations, thermal stress, and mechanical forces. Steel fiber castables can improve their thermal shock resistance and mechanical vibration resistance.

Lightweight insulating castable
Widely used for high-temperature flue and duct linings, it can also be used for acid-resistant projects such as acid pools and tanks in industries like CFB boilers, petroleum, chemical, and non-ferrous metallurgy.

The preparation process of low cement castable is very strict, so there are many factors that affect the performance, mainly including ultra-fine powder, aluminate cement and admixture, refractory aggregate and admixture. The amount of refractory aggregate and water is also an important factor.

Coal spray pipe using refractory material
The coal spraying pipe uses refractory castable materials for kilns with harsh and severe operating conditions, made from high-strength materials such as corundum and mullite as aggregates, and ultra-fine powder as a binder to create high-performance refractory castables.

High-strength alkali-resistant refractory material
Mainly used in the lining of preheaters, pipeline linings, and cooler linings of cement rotary kilns, alkaline refractory castables can also be used in the preheaters of lime kilns.

The anti-caking pouring material adds silicon carbide, which has very little adhesion to the raw materials burned in the cement kiln, significantly reducing the phenomenon of cement raw materials clumping at the kiln tail discharge slope and other areas.

Corundum-based castables include corundum castables, corundum plastic materials, corundum ramming materials, and corundum wear-resistant materials. Corundum-based products are made from refractory materials with an Al₂O₃ content greater than 90%, primarily consisting of corundum as the main crystalline phase, and are compounded with appropriate amounts of dispersants, setting agents, stainless steel fibers, according to strict formulations.

Fused alumina silicon carbide castable
The corundum-silicon carbide castable made by combining corundum and silicon carbide has strong wear resistance and also has resistance to corrosion from acidic and alkaline materials.

Non-stick aluminum casting material
Non-stick aluminum casting material for aluminum melting furnaces is designed for the domestic aluminum melting industry. During the aluminum melting process, it does not produce aluminum dross, does not form corundum tumors, and prevents the elements in the refractory materials from reacting with the molten aluminum solution, thereby avoiding impurities from entering the aluminum alloy and affecting its quality.

The iron trench self-flowing pouring material has strong resistance to iron water and slag erosion and scouring, good thermal shock resistance, good oxidation resistance, and is easy to construct. It can be quickly baked without cracking, does not stick to iron slag during use, and has a long service life.
