Calcium Aluminate for Deoxidation and desulfurization In Metallurgy

详情

1)If deoxidation is the main process, you shall add it to the capsule bottom directly before tapping. The amount of adding depends on the carbon content in the molten steel, and is generally allocated with steel of **6kg/***0kg. One quarter before tapping, you shall add ferromanganese, ferrosilicon and aluminum with the general amount. After tapping, you shall add manganese, ferrosilicon with general amount to the carbon steel, without adding any other alloys and aluminum feed line, and the steel ladle only needs to be refined by Argon blowing process. If you use the product to deoxidize, the increasing carbon agent (SiC) can be reduced by ****0% in volume.

2) If desulfurization is the main process, you shall add it to the capsule bottom with one-third of usage, but it must be at the capsule bottom of the steel pounding. With the outflow of molten steel, you shall add two-thirds of it. And the steel usage of **8kg/***0kg is depended on the original sulfur content in steel and the using results.

Calcium Aluminate for Metallurgy is a kind of auxiliary material for steelmaking, as it speeds up secondary metallurgy process, especially faster desulphurization, Improves overall steel cleanliness and makes high grade steel with cheaper cost.
