Large Size and Special Shapes of Zirconia Slide Plate for EAF Taphole Slide Plate Mechanism

Steel-Making by EAF

Nowadays Steel-Making way in the world is mainly by EAF. The smelting process is generally divided into melting period, oxidation period and reduction period. In the furnace, not only oxidation atmosphere but also reduction atmosphere can be created, so the efficiency of dephosphorization and desulfurization is very high.

Steel-Making by EAF is mostly used to produce high quality carbon structural steel, tool steel and alloy steel. This kind of steel has good quality and even performance. At the same carbon content, the strength and plasticity of Steel-Making by EAF are better than that of steel-making by open hearth way. The main raw material of steel-making by EAF is scrap of similar steel grades, and sponge iron is also used to replace some scrap. Adjust the chemical composition and alloy element content by adding ferro-alloy.

Almost all the EAF is more than 150 tons production capacity in the abroad, they are used to smelt ordinary steel, and 60-80% of the output in many countries is low carbon steel. Due to the shortage of electric power and scrap in China, it is mainly used for smelting high-quality steel and alloy steel.
