It is with furnace of intermediate frequency fusion below exemple, elaborate the note that uses company in use: (1) intermediate frequency electric induction furnace should use special commutate transformer, heighten power supply tension, restrict the empty running of transformer. (2) normative installation, shorten the line is connected between power source of high pressure, transformer, intermediate frequency, electric stove, choose purity higher T2 copper talent or the copper that do not have oxygen, especially induction coil and water-cooling cable, increase its cut area to be able to reduce electric current effectively to heat up loss. (3) choose proper size and electric stove of frequency intermediate frequency according to foundry technology, increase power density to fuse in order to rise efficiency, reduce additional loss. (4) the steel casing body of heater that first choice takes furnace lid, reduce furnace wall and mouth hot loss and electromagnetism loss. Joint of crust of body of heater prevents metallic contact to form short circuit in unit process of cargo bandling. (5) make sound foundry technology, from modelling, anthology makings, fused, pouring, heat treatment, clear wait for normative technology operation, science management, in order to reduce specific power consumption. (6) strengthen equipment manages and safeguard, reduce fault rate, safeguard produces success. (7) the join part contact that often examines system of each electric conduction is good, especially the bolt of water-cooling cable and induction coil joint originallies whether closely, boots of insulation stage, insulation must examine every year. (8) forbidden in fusion process cut off the power cut off the water supply, should notice temperature giving water is mixed at any time in fusion process hydraulic, make hydraulic maintain in 0. 1 ～ 0.
3MPa, temperature giving water maintains it is under 55 ° . (9) when feed in raw material is operated, cold wet charging answer first stoving, cannot add frit juice directly inside, the metal is cut had better avoid to use when the first furnace is used, because the metal is cut can permeate lining clearance; When the chamber of a stove or furnace must burn heat to be controlled to 1000 ℃ , just can enter iron fluid, of the chamber of a stove or furnace heat can join iron piece induction to heat. (10) charging freezes sealed time cannot too long, lest cause furnace explosion accident; After agglomeration good lining, appropriate uses 30 ～ the rated power of 50 ％ , successive job 5 furnace above.
