Calcined Bauxite of Foundry Sand Used for Refractory Products and Investment Casting Customizing Requires

1. Brief introduction of our company

In view of the fierce competition in the raw material market, we pay more attention to the quality of products and firmly believe in the concept of "quality-oriented, honest operation". We also cooperate with mining companies to develop customized products. Using our product, the casting is easy to be shelled, not deformed, not easy to shrink, with good finish and high yield. After that, remind the customer not to be greedy for cheap choice of cheap sand so as not to affect the casting finished products.

It is recommended to choose the products of regular mullite manufacturers with reasonable price, quality and more guarantee. We hope that through our efforts and careful service, we can provide customers with cost-effective products and contribute to the development of the investment casting industry.

2. Product description

As we all know, China is the world's leading supplier of bauxite, producing over three million tons per year for refractory, abrasive, and welding applications.

Calcined bauxite of foundry sand is made of excellent bauxite ores, fired in a rotary kiln to impart its superior abrasive qualities, hardness, and long-term frictional resistance.

This materials are in stable index, homogeneous structure and excellent high-temperature performance. Its high alumina and low iron make calcined bauxite be the ideal raw material in refractory and abrasive products.

3. The Physical and Chemical Indicators of Calcined Bauxite of Foundry Sand

4. Calcined Bauxite of Foundry Sand Applications:

1. Aluminium metallurgy

2. Precision casting / Investment casting: bauxite grog fines can be made into mold for precision casting.

3. Refractory: high alumina bauxite’s refractoriness can reach 1780°C.It is charactered by good chemical stability and mechanical performance. (Al2O3 ≥48% with low Fe2O3)

4. Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under 2000°C-2200°c in the electric arc furnace.After a series of processing, it can become aluminium silicate refractory fiber, which can be made into fiber blanket, plate,cloth.

5. Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.

6. Producing bauxite cement

7. Abrasives

8. Ceramics industry

9. Chemistry industry for all kinds of aluminium compound.

5. Our Working Plant
