The electrical operation of the muffle furnace is the basis and guarantee for the formulation of the smelting system

   To smelt a furnace of steel, we must first determine how much energy is needed. Electric arc furnace steelmaking with electric energy as the main energy source must first ensure a safe and stable supply of electricity. Electric arc furnace is a huge user of electric energy. The capacity of the three-phase electric arc furnace transformer can reach several tens of megavolt-amperes, and the required power value fluctuates sharply and greatly during furnace operation. There is a question of how to provide electrical energy for electrical operation.

    When formulating a process system, electrical issues such as transformer capacity, transformer utilization factor, interference to the grid (flicker, harmonics), power factor and other electrical issues should be considered, because these are related to basic process issues such as smelting time, smelting reaction, and tapping temperature. . Adopting a reasonable power supply system can not only ensure the smooth flow of the process, but also shorten the smelting time, reduce the electricity consumption per ton of steel, and reduce the interference to the power grid.

    A normal working ultra-high power electric arc furnace must have a reasonable electrical operation system to match it. If the electrical operation system is unreasonable, it will not only increase power consumption, increase electrode loss, serious corrosion of refractory materials, and extend the smelting cycle , It may even make the operation impossible
