Recently, China's first 80-ton low-frequency single-electrode gas-safety electroslag remelting furnace was formally put into operation at CITIC Heavy Industry Machinery Co., Ltd. This not only means that CITIC Heavy Industries has made another breakthrough in the field of high-purity, high-quality steel ingot manufacturing. What's more important is that it can solve the demand for high-end forgings in China's power stations, nuclear power, aerospace and other fields, and improve the market competition of domestic high-end forgings. force. Different from electric furnace steelmaking, electroslag furnace is a consumable electrode that uses liquid resistance to generate heat energy to melt into the slag pool. After metal droplets are cleaned by slag, they are crystallized into slag in a water-cooled crystallizer. Smelting equipment. According to the introduction of the top three of Yangtze River, a heavy-duty casting and forging plant of CITIC Heavy Industries, the 80-ton electroslag furnace uses 1-3 Hz and 90 kA low-frequency currents, micro-positive pressure inert gas protection, constant melting speed, in-phase inverse parallel short net, and double Stove car and many other innovative technologies can realize computer automatic control of the remelting process. It is unique in design, energy-saving, environment-friendly, safe and reliable. Especially in the structural design, due to China's power energy use policy, strict restrictions on the use of single-phase electricity, especially heavy machinery companies are not allowed to directly use single-phase electricity. To this end, CITIC Heavy Industries adopted a three-phase power supply unit single-phase low-frequency power supply technology solutions. This low-frequency power electroslag furnace not only overcomes the disadvantages of the unbalanced, low-frequency power factor operation, large maintenance workload, and unreliable operation of the large and medium-sized power-frequency electroslag furnaces in the power supply mode, but also plays a low-frequency power supply. Minimal magnetic field interference, no skin effect, even power output, high power factor. It is reported that after the 80-ton electroslag furnace is put into operation, it will form an annual production capacity of 10,000 tons of high-quality electroslag remelted steel ingots. At the same time, it has established a world-class high-end casting and forging process equipment production system, together with the existing 80-ton electric furnace, 150-ton ladle refining furnace, 18,500-ton hydraulic pressure unit, and heavy-duty heat-treatment engineering department, together with a 9×30-meter gantry threshold. A batch of top-notch large-scale numerical control processing equipment such as milling machines will help companies build world-class high-quality casting and forging bases.
