Silicon Metal Furnace

Industrial silicon (also called crystalline silicon, metal silicon) is one of the important materials in modern industrial production. Industrial silicon is widely used in electronics, steelmaking, optics, machinery, automobile manufacturing, chemical industry, metallurgy, medicine, national defense and other fields. At present, the application of industrial silicon is still developing new fields, such as manufacturing solar cells and silicon nitride synthetic optical fibers. Solar energy has become the most concerned green energy industry.

ADVANTAGES

Advantages of CHNZBECH Silicon Metal Furnace

The advantages of replacing one three-phase furnace transformer with three single-phase side outlet transformers are as follows:

  • The total length of secondary circuit is nearly 2/3 shorter than that of one three-phase transformer, which saves investment in secondary circuit, increases power factor and saves electricity. Three single-phase transformers are arranged 120 degrees from the main body of the furnace to each other. The load distribution is balanced and the power of three electrodes is balanced. The problems of strong and weak phases in the smelting of a three-phase transformer are solved, which creates favorable conditions for improving product quality, output and reducing power consumption.

  • Energy-saving current density of conductive copper tubes and water-cooled cables promulgated by the Ministry of Chemical Industry are used in the secondary circuit, with current density of 2.5-3A/ mm2 and current density of copper bushes and electrodes of 1.1-1.9A/cm2. It can run at 30% overload. The secondary circuit is safe and reliable. The implement of the above two items can increase the natural power factor of ore heat by 8-12%.

  • The holder adopts our company's patented products, bellows pressure rings and water-cooled protective jackets with bottom rings, which can protect the copper tile and pressure rings with water-cooled from damage caused by high temperature and ignition. It not only prolongs the service life of copper tile and pressure rings, but also greatly improves the operating rate of the holder equipment and creates reliable conditions fo hrigh yield.

  • Using tamping furnace and pusher, a batch of material is weighed accurately when proportioning, and the mixture is evenly loaded and unloaded into the middle feed bin by belt conveyor. By adding the feeder into this submerged electric arc furnace, the feeding of silica and reducing agent is uniform, which solves the common problem of automatic feeding segregation in large and medium-sized industrial furnaces, and greatly reduces the unit power consumption.
