Industrial electric furnace, is to use electricity as the power to heat the furnace. Foundry use of electric furnaces are generally medium-frequency electric furnace, medium-frequency electric furnace is divided into three parts, the power system, the water circulation system and the furnace, because of the difficulty of maintenance of electric furnaces, are generally manufacturers to come to the maintenance. And we used to use the cupola is not the same.

1, cupola stone melting process, the electric furnace is dissolved, which is the essential difference between the 2 furnaces. The effect is (5 elements do not say the dosage process must be controlled), the dosage must be controlled cupola on the charge is not fussy, can be used, trace elements in the melting process has been burned or filtered through the conversation; electric furnace on trace elements can not be or is difficult to control.

2, oxide has no effect on the melting process of the cupola, only the corresponding increase in slag; electric furnace is more sensitive to oxide, in addition to slag increase, the magnetic field required for heating has a great impact, will increase the power loss.

3, cupola shortcomings - the charge is not easy to be too large, otherwise it will produce the phenomenon of shed material

Electric furnace - as long as the lump of charge can be put in.

This shows that the use of electric furnace is very convenient, this is the progress of the times ah.
