Arc Melting Furnace
Small Arc Melting Furnace can ready temperatures up to 1,800 °C (3,272 °F), while laboratory units can exceed 3,000 °C (5,432 °F). this small arc melting furnace Can melt various kinds of refractory metals.During the formation of droplets at the lower end of the electrode，There is a certain physical and chemical reaction that removes a part of the gas impurity.
[vacuum consumable electric arc furnace]
The technology characteristic of vacuum consumable electric arc furnace is melting in water cooled copper crystallizer, which overcomes the disadvantage of metal contamination with refractories.At the same time, under the condition of high water cooling, the steel liquid is solidified and crystallized, and the uniform, non shrinkage and compact ingot can be obtained.vacuum consumable electrode arc furnace，is carried out under the action of low DC voltage and high current arc.
The arc plasma zone is formed between the end of the consumable electrode and the molten pool, which has a very high temperature.The end of the consumable electrode can be melted down here，Some non-metallic inclusions, such as oxides and nitrides, are removed under vacuum and high temperature.
Because the technology of vacuum consumable electric arc furnace can remove gas and non-metallic inclusions and remove some harmful impurities with low melting point, the cold and hot processing properties, plasticity and mechanical properties and physical properties have been significantly improved.reduction of carbon has been removed to achieve further purification.
Advantages Of Electric Small Arc Melting Furnace
1,Reduce energy consumption:This greatly reduces the energy required to make steel when compared with primary steel making from ores.
2,Has good flexibility: while blast furnaces cannot vary their production by much and can remain in operation for years at a time, EAFs can be rapidly started and stopped, allowing the steel mill to vary production according to demand.
3,Small and miniaturization: convenient operation, furnace and electricity integration design,easy to transport.
