Why is silicon slag used in iron and steel making?

People who often come into contact with the ferroalloy industry must be familiar with this product-silicon slag. In fact, silicon slag is not a metallurgical material specially produced, but a by-product of the production of ferroalloy materials, and the price is low.

Silicon slag contains a certain amount of silicon element. The silicon slag can be re-crystallized and purified from the beginning. After purification, the silicon material can be reused, so that the silicon slag can be fully used. The cost of steel increases the profitability of the manufacturer. Therefore, after comprehensive consideration, silicon slag is currently used in pig iron making, steel making and casting.
