Silicon slag advantages and uses

When it comes to "slag", many people think that slag is equivalent to waste. However, in the ferroalloy industry, silicon slag is a representative iron alloy product.

Silicon slag has many advantages. The silicon slag contains a certain amount of silicon. In steelmaking, the deoxidation effect can also be achieved.

Silicon slag itself is the slag of metal silicon. The price is relatively cheaper than that of metal silicon.

In the case of rising ferroalloy prices, many manufacturers choose to buy silicon slag products. Not only reduce the cost, but also can achieve the corresponding effect.
