B. 3 T induction melting furnace process flow
The 3 T induction melting furnace complete set of equipment is used for the melting of brass and red copper materials and combined with the casting process to complete the rough processing and finishing of copper materials. The operations staff copper raw materials and scrap into the furnace → material by heating to a rated frequency heating equipment melting temperature . 1 . 7 00 → deg.] C by playing the slag, in addition to a series of gas treatment processes such as the molten liquid metal after preliminary purification → hydraulically furnace The metal liquid in the body is poured into the transfer ladle → the casting process is carried out through the ladle.
C. 3 T induction melting furnace composition requirements:
The intermediate frequency power supply is an AC – DC – AC static frequency conversion device that converts 50Hz three-phase power frequency electrical energy into single-phase electrical energy. Using the principle of electromagnetic induction, the heated material is placed in an alternating magnetic field to generate eddy current loss and generate heat, which meets the requirements of melting . The heating method has the advantages of fast heating, less burnout, low labor intensity, can ensure product quality and easy to organize automatic production lines.
