Combined type connected power frequency induction furnace

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of metal casting and smelting, in particular to a combined type conjoined power frequency induction furnace. Background technique [0002] At present, the "upward-drawing continuous casting method" is used in China to produce oxygen-free copper and copper alloys. The power frequency induction furnace is one of the main equipments produced by the up-drawing continuous casting method. The power frequency induction furnace is usually used in conjunction with the extrusion machine. The heating furnace is a fast heating device, and the feeding frequency is generally about 2 times / minute. Since the copper and copper alloy to be extruded are generally about 100-1500kg / block, it is unrealistic to rely on manual feeding to the power frequency induction heating furnace, and it is necessary to rely on mechanical feeding to ensure safety and production efficiency. At present, domestic processing manufacturers mainly re...

Problems solved by technology

Due to the large tonnage of the crane supporting the extrusion machine, the cost is very high; the crane has been preparing and loading materials for the power frequency induction heating furnace for a long time, which affects the lifting work of extrusion and subsequent processes; at the same time, the crane is a special equipment and requires Skilled workers with special operation qualifications perform auxiliary operations, which increases production operating costs

At present, the pace of transformation of power frequency induction furnaces is relatively slow. The combination of split power frequency furnaces is the process of flowing copper and copper alloy melts from the melting furnace through the chute to the temperature. The copper alloy melt flow in the high temperature state is fully exposed. In the air, a large amount of heat is radiated. At the same time, the molten material absorbs harmful gases such as oxygen and hydrogen in the air, and undergoes a violent oxidation reaction. The oxides form thick smoke and emit, which not only causes pollution to the surrounding environment, but also loss of constituent materials in the melt due to partial oxidation
