two main ways to produce steel
In the modern industry, two technologies are used to produce steel, one is Blast Furnace Steelmaking based on iron ore, and the other is Electric Arc Furnace Steelmaking, which is made of scrap steel.
1,Blast Furnace Steelmaking
Steelmaking with iron ore as raw material accounts for 70% of world steel production.
The main raw materials include: iron ore, coal, limestone and recycled (waste) steel. Iron ore is reduced to iron during steel smelting and then converted to steel.
The steel production process with ore as the main raw material mainly includes: blast furnace ironmaking supplemented by converter steelmaking, direct reduced iron supplemented by electric furnace steelmaking.
2,Electric Arc Furnace Steelmaking
Steelmaking from scrap steel accounts for 30% of global steel production.
The main inputs include scrap steel and electricity, which are smelted in scrap steel furnaces.
Depending on the equipment configuration and the availability of scrap, other sources of metallic iron such as direct reduced iron or liquid molten iron can also be used in the electric arc furnace process.
Shandong zbbssteel has 10 years of steelmaking experience. Blast Furnace Steelmaking and Electric Arc Furnace Steelmaking are mature and efficient. Next time, we will give you a detailed introduction to the specific details of the two technologies to help you further understand steelmaking technology.
