Raw materials for iron and steel metallurgy

Refers to the raw materials used for smelting steel and iron. There are mainly iron ore, manganese ore, iron-containing waste and flux. Iron and steel smelting, the general term for steel and iron metallurgical processes.
Industrially produced iron is classified into pig iron (with a carbon content of more than 2%) and steel (with a carbon content of less than 2%) according to its carbon content. The basic production process is to smelt iron ore into pig iron in an ironmaking furnace, then use pig iron as a raw material to make steel by different methods, and then cast into steel ingots or continuous casting billets.

Metallic deoxidizers

This method of deoxidization involves adding specific metals into the steel. These metals will react with the unwanted oxygen, forming a strong oxide that, compared to pure oxygen, will reduce the steel's strength and qualities by a lesser amount.
Below is a list of commonly used metallic deoxidizers:
Ferrosilicon, ferromanganese, calcium silicide - used in steelmaking in production of carbon
steels, stainless steels, and other ferrous alloys
Manganese - used in steelmaking
Silicon carbide, calcium carbide - used as ladle deoxidizer in steel production
Aluminum dross - also a ladle deoxidizer, used in secondary steelmaking
Calcium - used as a deoxidizer, desulfurizer, or decarbonizer for ferrous and nonferrous alloys
Titanium - used as a deoxidizer for steels
Phosphorus, copper(I) phosphide - used in production of oxygen-free copper
Calcium hexaboride - used in production of oxygen-free copper, yields higher conductivity copper than phosphorus-deoxidized
Yttrium - used to deoxidize vanadium and other non-ferrous metals

The main function of steelmaking deoxidizer is to remove oxygen in steel, so what kind of harm will it cause if there is oxygen in steel. When molten steel is solidified, the excess oxygen in it combines with other elements in the steel to form non-metallic inclusions, which destroys the continuity of the steel matrix and reduces the strength limit, impact toughness, elongation and other mechanical properties and magnetic permeability of the steel. Performance, welding performance, etc. If the oxygen content in the molten steel is too high, it will react with the carbon in the steel again during the casting process to produce CO gas, which will cause the steel ingots (slabs) to produce pores, looseness, and even rise and other defects. In severe cases, it will cause the steel ingots (slabs). scrapped. Oxygen can reduce the solubility of sulfur in steel, aggravate the harmful effects of sulfur, and make the hot embrittlement tendency of steel more serious.
From this, we can understand why steelmaking deoxidizer must be added for deoxidation during steelmaking.
