The introduction of the low micro carbon ferrochrome furnace

The electrode lifting hydraulic proportional valve speed automatic regulator adopts a control system composed of a Siemens programmable controller, which is simple and reliable to operate.Electrode lifting mechanism adopts oil cylinder transmission, which is flexible, safe and reliable.The tilting of the furnace body adopts the form of hydraulic transmission, and the integrated block hydraulic valve. The hydraulic station is equipped with two plunger pumps, one for use and one for backup, and is equipped with an energy storage tank, which has the function of maintaining pressure. Six large cross-section water-cooled cables, conductive cross arms, flexible compensators, copper bars, and energy-saving short nets arranged in a triangular space. The impedance value of the short network is ≤0.5+ j 2.3mΩ, and the unbalance of the three-phase impedance is ≤5%.
