Ferro Silicon Chromium

A ferroalloy composed mainly of silicon, chromium, and ferro. Also known as silicon chromium ferroalloy. It is mainly used as a master alloy for the production of medium, low and micro carbon iron by electrosilicothermal method. Used as deoxidizer (replacing ferrosilicon) and chromium additive in steelmaking. Generally, it contains Cr>30%, Si>35%, and the balance is iron and a small amount of impurities. Classified according to carbon content, such as carbon content ≤0.06%, ≤0.10%, ≤1.0%, etc.

Its production process is divided into two types: one-step method (usually called "slag-containing method" or "ore method") and two-step method (usually called "slag-free method"). The raw materials used in one-step smelting include silica, chromium ore and coke. The raw materials used in the two-step smelting include silica, carbon ferrochrome, and steel scraps. Both smelting methods use coke as the reducing agent.
