Sintered Ca Aluminate
Sintered Ca Aluminate Back to Refractories

Calcium Aluminate Cleansing Agent (sintered type) is used in steel-making. Since its low melting point, it can be easily melted in the steel-liquid to get rid of sulphur. Meanwhile, it keeps slag flow well.

Character & uses
Our products have the following features:
1. Anti-moist, Anti-powder, couldn't go to bad in storage and transpotation.
2. It's components of mineral is basically same as pre-melt Type Calcium Aluminate.
3. Low melting point. it can be easily melted in steel-liquid to get rid of sulphur.(DFS-1,DFS-2,DFS-3)
4. Slag flow can be kept well.

IPhysical Specification and Usage

1Sinter forming in a shorter time, low conglutination and good flow fluidity.

2Sinter has good sulfur adsorption, also to oxygenate, phosphor and other sundries of the steel.

3Highly extended the using time of the steel bow and raised the refine effect.

Specialty as follows:
1
Dampproof, Non-pulverization, Non-metamorphose during storage and transportation.
2
Faster in filter sinter, can quickly pure molten steelDFS-1DFS-2
