The Addition Of Silicon Calcium

ZhenAn International Co., Limited is one of the most reliable manufacturers and suppliers of the addition of silicon calcium in China. With abundant experience, we warmly welcome you to wholesale discount the addition of silicon calcium in stock here from our factory. Quality products and reasonable price are available.

But at high temperature, lime and silica first form calcium silicate slag with low melting point, which makes carbon reduction reaction difficult to carry out. Calcium has a low boiling point and is easily volatilized to produce calcium vapor. And SiO2 is reduced to SiO(gas), so the gas discharged from the furnace is CO, Ca(gas) and SiO(gas).

The loss of calcium and silicon in furnace gas is about 10% each. SiO(gas) and Ca(gas) react with carbon when passing through the material layer, and most of them are converted into CaC2 and SiC, so the reactivity of carbon reducing agent is very important for smelting silicon calcium alloy. Calcium oxide and silica with carbon at high temperature to produce CaC2 and SiC, is the production of silicon calcium alloy intermediate products. In the end, some of it remains in the slag, so the production of silicon calcium alloy is smelted with slag. In fact, the method of industrial production of silicon-calcium alloy is realized by using CaC2 as the transition product. The density of silicon calcium alloy is slightly smaller than the slag, and the smelting process of silicon calcium alloy is basically concentrated in the upper part of the melting pool, which is the characteristic of smelting silicon calcium alloy. Special measures should be taken to separate it from the slag.

How can we guarantee the quality for Calcium Silicon?

Always a pre-production sample before mass production;Always final Inspection before shipment.
