Product introduction: Tabular corundum is a kind of pure sintered corundum that does not add any additives such as MgO, B2O3 and so on. It has a coarse and well-developed α-Al2O3 crystal structure. The content of Al2O3 is more than 99%. .
(According to the molecular structure, corundum can be divided into fine material, granular, flake, spherical, etc.)
Product features: high purity, high whiteness, low apparent porosity, low water absorption

Product application: Tabular corundum can be used as the main component in aluminum-carbon, aluminum-magnesium-carbon, magnesium-aluminum-carbon, magnesium spinel, aluminum-chromium refractory bricks; It can also be introduced into high-alumina amorphous refractory as a component of enriched alumina.
It can be widely used in steel, casting, ceramics and other industries, and its application in the steel industry covers almost the entire process of iron making and steelmaking.

 

Characteristic:

1. Complete crystallization, High purity up to 99.5% Al2O3
2. Good resistance to alkalis and mineral acids
3. Low water absorption less than 1%
4. High hardness and toughness
5. High thermal conductivity
6. Excellent thermal shock resistance
7. Good abrasion resistance.
8. High volume stability
9. High anti-bending strength

The process design, process control technology, and equipment of the entire production line are independently designed and developed by ourselves. Many technologies are the first in the world, which broke the long-term control of high-end refractory materials and products by foreign countries and fully localized. This production line starts from the fine control of the raw materials for aluminum hydroxide production, produces high-purity aluminum hydroxide raw materials, and then undergoes high-temperature flash roasting technology to produce light-burned alumina with high A-cabinet content required for the sintering of high-end tabular corundum. Finally, after powdering, forming, sintering, crushing and screening, the whole process is automated in sinus control, which provides guarantee for product quality and realizes high-quality control from ore to the final products.





1. High-quality raw materials
The high-quality aluminum hydroxide we produce provides high-quality raw materials for tabular corundum. The raw material has the characteristics of low Na content and low content of heavy metals and other impurities. This high-quality aluminum hydroxide production line has an annual production capacity of 600,000 tons, ensuring that it provides stable and consistent high-quality raw materials for the production of tabular corundum.

2. Advanced technology
Our tabular corundum production line is the only advanced corundum production line in the world that integrates raw material preparation and sintering. It uses high-quality aluminum hydroxide as the raw material, and the production process is strictly controlled. The alumina raw material required for sintering corundum adopts high-temperature flash roasting technology, and its a-phase content and specific surface area are both controllable, becoming the world's first; Thus, the high-quality tabular corundum products are produced. The sintered corundum production line adopts remote centralized control to reduce the influence of human factors and provide a strong guarantee for product quality.

3. QC systems
As an ISO 9001:2015 certified manufacturer, it possesses sophisticated manufacturing and inspection equipment, provides 100% inspection and reporting on each product delivered to its customers so you can be assured that 100% of your parts are manufactured and tested to the highest quality standards. The company maintains stringent quality processes and standards in the industry to ensure an effective Quality Management System, continual improvements, and excellence in customer satisfaction.

The company holds itself to the highest quality standards that control everything from incoming raw materials to final factory production. All materials are tested to ensure they meet industry standards before entering the manufacturing phase. Additionally, every lab is ISO9001 accredited for all routine QC tests performed at each facility.

The company is committed to the production and supply of tabular alumina products that meet customer requirements and industry standards. Our goal is to continually improve our products, services and our quality management system by establishing and reviewing quality objectives on a consistent basis.
