Ferroalloys are alloys formed by iron elements and other elements, which can be divided into silicon-based, manganese-based, and chromium-based alloys according to the elements contained.
Silicon manganese and ferrosilicon have two main uses, one is as a deoxidizer, and the other is as an alloying agent.
When steelmaking, we use oxygen blowing and other methods to remove harmful substances such as carbon, phosphorus, and sulfur in molten iron. This process will increase the oxygen content in the molten iron, which will damage the mechanical properties of steel. At this time, we add some elements that have stronger binding force to oxygen than iron and are easy to form oxides to remove oxygen in the molten iron. This is called deoxidation. Manganese, silicon, and elemental elements all have this effect.
Ferro Alloy elements have their own functions. For example, silicon can improve the elasticity and magnetic permeability of iron. Tool steel, structural steel, and spring steel all use silicon. Normal steel contains 0.15%-0.35% silicon, structural steel contains 0.40%-1.75% silicon, tool steel contains 0.30%-1.80% silicon, spring steel contains 0.40%-2.80% silicon, and stainless acid-resistant steel contains silicon. Silicon is 3.40%-4.00%, heat-resistant steel contains silicon 1.00%-3.00%, and silicon steel contains silicon 2%-3% or higher. For example, manganese can reduce the brittleness of steel, improve the hot workability of steel, and increase the strength, hardness and wear resistance of steel. Manganese is an indispensable functional basic raw material for the production of high-quality steel. It can remove impurities such as oxygen during the steelmaking process to improve strength and hardness.
