Design of Refining Furnace for Ferroalloy
Introduction
Ferroalloy is an alloy composed of iron and other elements. It is an important raw material for steelmaking, casting and other purposes, and its production process is mainly divided into smelting and refining. Refining is a necessary link to improve the quality of ferroalloy products. It mainly includes chemical analysis and physical separation. The production of refined metal requires the use of refining furnaces.
Refining furnace design
Electric arc furnace is widely used in the smelting and refining of ferroalloy. It is based on the principle of arc heating, which uses electricity to heat the furnace and produce high temperature, so as to smelt and refine ferroalloy.
Design of electric arc furnace process
The electric arc furnace is composed of furnace body, furnace cover, electric superheating element, blowing device, furnace door, cooling system and arc stabilizer, etc. The furnace body is equipped with refractory brick, fire clay and other heat resistant materials, and is designed with ladder structure. The arc stabilizer is used to stabilize the arc to ensure the smooth smelting and refining process. The blower device is installed through the furnace cover and connected to the furnace body, which is used to blow the protection gas for arc control, so as to protect the electrodes, the lining and the raw materials from the damage. The furnace door is mainly used to charge, discharge and sample raw materials. The cooling system is used to cool the furnace body and furnace cover, so as to ensure the normal and safe operation of the equipment.
Conclusion
The design of refining furnace for ferroalloy mainly includes electric arc furnace, process design and components design. The electric arc furnace technology combines smelting and refining, which is widely used and has good market prospects. The design of the refining furnace should consider the type of the raw material, the purpose of the smelting, the economical and reasonable use of the fuel and the overall applicability of the equipment. On the basis of comprehensive consideration and analysis, the refining furnace with excellent performance and reasonable configuration can be designed, which is an important guarantee for the safety, energy saving and high production efficiency of the production.
