Medium frequency melting electric furnace is often used in the field of some metal material refining, this kind of medium frequency melting furnace is very easy to manipulate, the actual operation is very easy and safe.
1.Melting electric furnace
Electric furnace melting electromagnetic energy for the heat source of the melting method of the collective name. Electric furnace melting, preferably gray cast iron and gray iron melting in turn, if the melting in turn, can enhance the application of many furnace wall deadline. According to the heating method is divided into electric solitary melting, electric arc resistor compound building melting, magnetic induction melting. Generally used for non-ferrous metals and aluminum alloy, tin, nickel and other metal materials refining.
2.The whole process
Electric furnace electricity by three electrodes to provide three-phase alternating current, recovery melting heat required by the electrode and slag touching the arc discharge and electric flow according to the charge and coal ash caused, that is, the heat in the internal structure of the charge caused, so the charge melting and chemical changes in the internal structure of the charge is carried out, therefore, the melting of the electric furnace is a passivation reaction and slagging at the same time to achieve, near the electrode of coal ash, because the temperature The ash close to the electrode, because of the temperature rise and slag in the reflection of the formation of vapor to reduce its relative density along the electrode upward, reaching the surface layer will spread to the surrounding level, while the lower temperature of the furnace charge is digested to absorb the thermal energy of superheated ash and melting, has melted the furnace charge and has reduced the temperature of the ash mixed together, due to its relative density increased and downward, when down to the deep layer of the electrode inserted, part of the level of fitness movement to the electrode and become a continuous Repeated part, and the rest of the part is again the foundation sinks to the end of the pile, and along with the furnace material under the melting surface for level fitness movement, is so the majority of the melt down into the lower more quiet slag layer, and carry out the slag and the overall goal of separation out.
