Vacuum Arc Furnace - VAF

Arc is one of the types of gas arc discharge. Gas arc discharge performance as electrode voltage is very low, but by the current of the gas is large, a dazzling white light, high temperature (5000K) arc zone. Huge thermionicemission from the cathode current density, as well as electronic since the lauch,which has positive ion layer near the cathode, form a strong electric field, the cathode emission electron automaically. A large number of electrons in the interelectively gaseous molecule collision ionization,produce greater amounts of positive ions and secondary electon, under the effect of electric field, the impact of cathode and anode, respectively, the results for high temperature.Cathode electron emission energy to get through,so the temperature is lowder than the anode. Electrode was part of positive ions and electrons composite heat release andheat generation. Electric arc furnace is using the principle of metal smelting furnace. Under the environment of vacuum arc furnace is vacuum arc furnace. Vacuum arc smelting with high Current, low Voltage operation, belong to the short arc. General electric arc voltage of the 22~65V, corresponding to the arc length of 20~50mm (the latter for big ingot).
