The invention provides a combined type connected power frequency induction furnace. According to the combined type connected power frequency induction furnace, the pollution of heavy metal oxides to the ambient environment is reduced, the content of zinc oxide dust in air is reduced, and the working environment of workers is improved; undercurrent type conversion between liquid copper of a melting furnace and a holding furnace is realized by utilizing a graphite base and a stopper rod; the smoke collection rate reaches more than 96% by utilizing a baghouse system; the feeding rhythm and the production efficiency of the subsequent extrusion procedure are guaranteed by using a feeding machine; crane men and cranes are released from heavy feeding work so as to preferably service in the subsequent procedure, so that the production and operation cost is reduced; copper blanking is put in the furnace by a robot arm of a clamping device, and feeding at an idle station of a feeding device is automatically finished by the robot arm in a stacking area, a photoelectric sensor and a PLC (Programmable Logic Controller); an intermission working mode is realized by the feeding device, and the dwell time of each station is fully guaranteed; and the feeding machine can move by virtue of a moving device.
