Product Advantages

1. Low sodium and micro sodium WFA can be provided. Na2O can be double 0.
2. Bulk density can really reach 3.6 g/cm3, which can meet needs of various high-grade refractory materials.
3. YUFA spends 24hours non-stopping melting the WFA, using a tilting furnace with a diameter of 6.5m in order to pursue the high-grade and stable quality.
4. Various specifications can be supported.

Applications

ap (6)

MONOLITHIC REFRACTORIES

Ideal materials for the production of large-scale ladle casting materials, high-grade iron trench casting materials, spraying materials, prefabricated parts and other unshaped refractory materials.

SHAPED REFRACTORIES

Corundum bricks, corundum and mullite corundum saggers, refining. The main raw material of various corundum products is corundum porous plug brick, integral spray gun, composite nozzle, high-temperature industrial furnace lining material etc.

ap (4)

1. White corundum powder is widely used in steel, cement, ceramics, petroleum and other industries.

2. It is an ideal raw material for making large-scale ladle castables, medium and high-grade iron trough castables, gunning materials, preforms and other unshaped refractory materials.

3. It is also the main raw material for various corundum products such as corundum bricks, corundum and mullite corundum saggers, corundum porous plugs for refining, integral spray guns and composite nozzles, and high-temperature industrial furnace lining materials.
