Calcium aluminate clinker(sintered) can be used in refining ladle to get rid of the sulphur and other useless component from steel liquid.

Character and usage:

1.Anti-moist,Anti-powder,could not 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

4.slag flow can be kept well
