What are the types of industrial silicon furnaces?
Author：
Industrial silicon production is a systematic process, in addition to the electrical equipment mentioned earlier, but also need many mechanical equipment to complete together, the following description of industrial silicon mechanical equipment.
There are many types of industrial silicon furnaces, and the mine heat furnaces that produce industrial silicon can be divided into single-phase furnaces, two-phase, three-phase, four-phase and six-phase electric furnaces and other structures according to the number of phases of the power supply current. However, it is usually common for single-phase furnaces and three-phase furnaces|There are reports of four-phase electric furnaces abroad. Mine hot furnaces are also divided into buried solitary electric furnaces and minggu electric furnaces according to the phenomenon of arc light.
Single-phase ore hot furnaceSome research units still use single-phase ore hot furnace for some specific uses and laboratory experiments. The single-phase ore hot furnace flame pool power current is single-phase, mainly used for laboratory experiments, and can also be used to produce calcium carbide and ferrosilicon, such as the former Soviet Union with 1000OkV-A single-phase electric furnace to produce ferrosilicon. Since the inductance is almost fully compensated, the power factor of the furnace can be increased to 0.95 despite the current intensity of up to 250 kA, making this single-phase furnace in a sense useful as a phase compensator for other furnace workshops in the plant.
Despite the high power factor, single-phase is not widely used in actual production, like other forms of two-electrode electric furnaces, and the most commonly used is the three-phase ore furnace
