Silicon slag is a by-product of the production of silicon metal, the residue left over from the refining of the ore and the solidification of the furnace walls.These residues contain silicon content 45-80%, and the use of silicon slag is relatively wide.

Silicon slag uses:

1. The main purpose of silicon slag is to be used as a deoxidizer and to extract industrial silicon in silicon slag, which can reduce costs and increase profits.Silicon slag is a substitute for ferro silicon.

2.Silicon slag contains part of the silicon components,which can also be used to purify industrial silicon.

3.Used for steel slag recycling of pig iron, general casting, etc., silicon slag can improve the furnace temperature, increase the fluidity of molten iron, high-quality slag discharge, increase the label, and update the toughness and cutting ability of iterative casting.

4. In the process of refining stainless steel by electric furnace, silicon slag is used as reducing agent to upgrade efficiency and output.
