Industrial Silicon Furnace

Smelting categories: Industrial siliconProduction: 24t-28t a day/piecePower consumption: 11000～13500KW·h/tDetailed description:一．Brand and use of industrial silicon alloy:Industrial silicon is also called the crystalline silicon or industrial silicon. The main purpose of industrial silicon is used as the additives of nonferrous alloy. Industrial silicon is also used as alloy agent of demanding silicon steel, and deoxidizer in smelting special steel and nonferrous alloy. After a series of industrial processing, industrial silicon can be made into single crystal silicon for the use of the electronics industry. Industrial silicon now is widely used in compound alloy, preparing high purity semiconductor materials, producing solar cells, making temperature resistant materials and organic silicon, etc. Our society has entered in the information age and in the industrial developed countries, it has been widely used in scientific research as well as electrical, aviation, machinery, chemical industry, medicine, national defense and other fields.Product levelCard number(code)                     Chemical compositionSi(>)Impurity content（≤）Sum of impurities  (<)FeAlCaChemical siliconSi—220399.50.200.200.030.5Si—330399.00.300.300.031.0Si—330599.00.300.300.051.0Si—44199.00.400.400.10Metallurgical siliconSi—55398.50.500.500.301.5Si—198.00.70-0.502.0三．The main equipment composition and the overview:Equipment composition of industrial silicon furnace(1)mechanical parts:Main equipment: the furnace body, short hood, flue gas delivery line, control systems (including electrode protection tube, electrode lifting oil cylinder, hydraulic pressure ring, hydraulic lifting gear with hanging cylinder), hydraulic brake, water-cooled cables, hydraulic system, water-cooled copper tube short-net, and system equipment of tapping off etc.(2)Auxiliary equipment: double beam bridge crane, hanging electric hoist, electrode lifting machine and furnace pounding machine, etc.(3)The parts of high and low voltage electrical equipment:This set of electrical equipment mainly include: high voltage power supply system, low voltage power supply system, low voltage electrical control system,and electrode lifting control system.Equipment composition:High voltage power supply system      1 setElectric furnace transformer           1 setLow voltage electrical equipment       1 set Including:(1) power supply power cabinet                     1 set(2) PLC cabinet                                   1 set(3) hydraulic control cabinet                        1 set(5) iron operation box                             1 set(6) hydraulic operation box                         1 set(7) oil-water cooler console                         1 set(8) regulating control box                           1 setNote: the power cabinet add three independent stand-by power switchs, for the needs of temporary adding load electricity.Electric control cabinet adopts GGD low-voltage switchgear, using the surface coating processing, with a beautiful shape.
