Introduction And Development Trend Of Electric Arc Furnace Equipment

Introduction and Development Trend of Electric Arc Furnace Equipment
An electric arc furnace is a specialized metallurgical equipment that generates high-energy electric arcs between dedicated electrode rods and furnace materials under a vacuum environment or protective atmosphere. The high temperature produced by the electric arc heats and melts elemental metals or alloy materials, so as to realize the purification and recrystallization of metal materials.
1. Composition of Electric Arc Furnace Equipment
The electric arc furnace is mainly composed of a melting chamber, electric arc gun, water-cooled melting crucible, high-frequency arc power supply, vacuum pumping system, water cooling system, vacuum measurement system and control system.
2. Industrial Chain Structure of Electric Arc Furnace
The furnace body of an electric arc steelmaking furnace consists of a furnace cover, furnace door, tapping spout and furnace shell. The furnace bottom and furnace wall are lined with alkaline or acidic refractory materials. In terms of the industrial chain, the upstream of the electric arc furnace industry mainly covers raw materials such as refractory materials and graphite, while the downstream is primarily applied to the iron and steel industry.
3. Market Demand of the Electric Arc Furnace Industry
Centering on the production goals of high efficiency, low consumption, green development and intellectualization, the technological development of electric arc furnace steelmaking has witnessed the continuous innovation of new technologies, processes and equipment, driving the steady upgrading of electric arc furnace steelmaking technologies and supporting equipment. In recent years, on the basis of the original high-efficiency and energy-saving smelting technologies, electric arc furnace steelmaking has made remarkable progress in green and clean production, as well as intelligent detection and control. It has significantly improved the green and intelligent level of the electric arc furnace steelmaking process and promoted the technological progress of the entire iron and steel industry.
