Product Description

Steel Smelting And Refining Equipment

 

  Steel smelting is an indispensable and important link in the steel industry, which is directly related to the quality and performance of steel products.


  Iron and steel smelting is a process in which impurities and other elements in pig iron are removed by high temperature heating to produce high-purity iron and steel products.

  Its technical principle mainly includes: melting reduction, carburizing and desulfurization and other key steps.

  Molten reduction refers to the reaction of pig iron with reducing agents such as limestone at high temperatures to reduce iron to metal.               Carburizing refers to the addition of appropriate carbon sources, so that the carbon content in metal iron reaches a certain level, 

so that it becomes steel; 

  The removal is to remove the sulfur element in the steel by adding an appropriate amount of calcium oxide or pure oxygen to improve the purity and weldability of the steel.


  • Electric Arc Furnace (EAF)
    • Working Principle: Electric arc furnaces use electric arcs generated between electrodes and the charge to produce heat. The heat melts the scrap steel and other raw materials, and chemical reactions occur to adjust the composition of the molten steel.
    • Structure: It mainly includes a furnace shell, electrodes, a charging system, a gas - cleaning system, and a tapping system. The furnace shell is lined with refractory materials to withstand high temperatures.
    • Applications: EAFs are widely used in the production of various steel grades, especially for high - quality alloy steels and stainless steels. They are suitable for using scrap steel as the main raw material, which helps to save energy and reduce environmental pollution.
  • Ladle Refining Furnace (LRF)
    • Working Principle: As mentioned before, LRF uses heating, argon - blowing stirring, and alloy addition to adjust the temperature and composition of molten steel, and remove inclusions and gases.
    • Structure: It usually includes a ladle, a heating system, an argon - blowing system, an alloy - adding device, and a control system.
    • Applications: It is widely used in the production of various high - quality steel products, such as steel for automotive manufacturing, construction, and electrical industries, to improve the quality and performance of steel.
