The introduction of electric stove
From;    Author:Stand originally

The bed before electric heat also is a kind of mine pyroelectricity furnace, it basically is the mixture of the broken bits that yields blast furnace or broken bits and metallic stock, depart of the precipitation inside advanced bed is given off respectively again, its shedding a line is wave motion, corrode consequently faster, it is the weak point of equipment, but the condition that compares dilution electric stove is close friends. The aluminous chromic brick that line of broken bits of the bed before electric heat of plumbic magnesian blast furnace and chromic broken bits make uses the effect pretty good.

Electric induction furnace

Electric induction furnace is to use electromagnetism induction principle, the facilities of a kind of hot project of fused metal, differ by frequency of working electric current can divide for not frequency, intermediate frequency, high frequency etc. Capacity of medium, high frequency electric induction furnace is lesser, frequency conversion installation cost is high, mix only the fusion at a few special metals or alloy, do not grant here expatiatory. By whether is there core to be able to be divided inside induction coil reach the electric induction furnace that do not have core to have core two kinds, the electric induction furnace that do not have core is general the capacity is lesser, basically use at medium, high frequency electric induction furnace, its fireproof material basically is the container that contains stock be fusinged (it is crucible commonly) , according to differ to be able to be used by frit stock. Alumina qualitative, quartz qualitative, black lead corundum is qualitative, qualitative the crucible that waits for material. By furnace model can divide for vertical and horizontal two kinds, channel of vertical furnace frit is in bottom, channel of horizontal furnace frit is in lateral.

This section basically introduces labour frequency (50Hz) electric induction furnace having core. Labour frequency has core electric induction furnace turns metal and the alloy such as copper, zinc, aluminous, iron generally with Yu Rong. Wet the shade that refine zinc place produces wants divide evenly piece be to be versed in frequency has core to the casting after fusing inside electric induction furnace becomes zincic ingot and sell as final finished product almost.

Labour frequency has core electric induction furnace basically is comprised by inductor and furnace noumenon, inductor is guide by induction coil magnetic body (core art and magnetism yoke) , protective sleeve composition, noumenal frit channel covers furnace to be outside core column and be linked together with the metal inside body of heater, there is fireproof material to fill up between frit channel and induction coil, its life is the key of whole furnace life, and furnace is noumenal life is quite long.

Frequency of frit copper industry has core electric induction furnace, now basically is vertical furnace, fireproof material has body of heater bricky build by laying bricks or stones and pound hit two kinds, be in the majority in order to pound dozen of type now, material with quartz arenaceous add boric acid or borax for many, the fireproof material of inductor room now is to mix quartz is arenaceous add boric acid to pound dozen.
