Silicon Metal Furnace

Silicon Metal Furnace

Silicon Metal Furnace Characteristics

        CHNZBTECH silicon metal furnaces main characteristics as follows:

        • Conducive to the endothermic reaction of industrial submerged arc furnace silicon smelting, which is beneficial for reducing electricity and material consumption.

        • Large amount of refractory materials, a large heat capacity, and good thermal stability.

        • Easy to achieve mechanization and automation, which can reduce employee labor intensity, reduce the number of employees in the enterprise, improve employee labor productivity, and save labor costs.

        • High power, high furnace temperature, and large heat capacity. After hot shutdown, the silicon arc furnace temperature is restored and the furnace condition is fast.

        • Power factor compensation technology is widely used to improve the capacity utilization rate of SAF and increase production.

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 silicon metal 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 cable for induction furnace 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 patented products from we submerged arc furnace manufacturer, 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 silicon metal 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 silicon arc furnaces, and greatly reduces the unit power consumption.

Difference between ferro silicon furnace and silicon metal furnace

        Silicon Metal refers to a high-purity silicon element product, with a purity of up to 99.999%. Industrial silicon is widely used in industry and can be used in fields such as semiconductors, solar cells, chemical industry, and ceramics.

        Ferrosilicon is an alloy of iron and silicon in a certain proportion, typically containing 15% to 90% silicon content. Ferrosilicon is mainly used as an additive in steel smelting, which can increase the toughness and strength of steel, and also improve the mechanical properties of steel.

        Main silicon metal furnace equipment differences are mainly concentrating on shell diameter, secondary current voltage, power consumption and daily productivity
