Applications

image (1)
Refractory Brick

The fused dense corundum is one of the first-choice raw materials for the production of high-performance unshaped and shaped refractory materials.

1.It’s widely used in industries such as steel, cement, ceramics, petrochemicals, etc.

2.It’s main raw materials for making blast furnace iron trough castables, ladle castables, ramming materials, preforms and other unshaped refractory materials.

3.It’s an ideal raw materials for various shaped products such as three continuous casting pieces, aire bricks, nozzle block bricks, etc.

4.It’s also an excellent material for making steel-making long nozzles, skateboards and various corundum bricks.

Grit and Fine Powder

0.1-0 mm, 0.2-0 mm, 0.5-0 mm, 1-0 mm, 1-0.5 mm, 3-1 mm,  5-3 mm, 8-5 mm, 10-5 mm, 25-10 mm, 100 mesh, 200 mesh, 325 mesh ……

Other spec are available upon request.

Product Advantages

1.Select high-quality industrial alumina, which is high purity, low impurities. YUFA control quality from raw materials.

2.Fused dense alumina has a high melting point and a high-volume density, which melted at high temperature and constant temperature in an advanced electric melting tilting furnace.

Melting Process

Tilting Furnace – Transfert – Cool Down – Barmac Crusher & Sorting – Sand Making – Warehouse

QC

To the fused dense corundum, the chemical composition of Al2O3, SiO2, Fe2O3,K2O,Na2O need to be tested, also very strick with the inspection of the bulk density.
