The installation and commissioning phase of Shaanxi Chengda Industrial Furnace Manufacturing Co., Ltd.'s 6000KVA zirconia corundum electric arc furnace in Zhengzhou has basically ended. This equipment is designed specifically for the smelting of high-end abrasives and refractory materials such as zirconia corundum, fused alumina, and mullite, marking a solid step forward in the company's technological strength in the field of industrial furnace manufacturing. We look forward to this innovative equipment bringing more efficient and high-quality smelting solutions to related industries.

Basic principles:

By utilizing the heat energy released by the arc generated between the electrode and the furnace charge, the furnace charge mainly made of alumina and zirconia is heated to a molten state, and a series of physical and chemical changes occur at high temperatures, ultimately smelting zirconia corundum.

Technical Parameter
Power supply: High power power is usually used to meet the high temperature requirements of electric arc furnaces, with common capacities of several thousand kilovolt amperes or even higher, such as the HY2.8-4000kVA zirconia alumina electric arc furnace equipment.
Electrode: Graphite electrodes are generally used, which have good conductivity and high temperature resistance. The diameter, length, and other dimensions of the electrode are determined according to the specifications and production requirements of the electric arc furnace.
Temperature control: It can achieve precise temperature control and raise the temperature inside the furnace to over 2000 ℃, meeting the high temperature conditions required for zirconia corundum smelting.

Equipment advantages
Efficient and energy-saving: adopting advanced short network structure, electrode lifting automatic regulator, etc., to reduce energy loss, improve production efficiency, and reduce production costs.
High product quality: It can accurately control the smelting temperature and process, making the chemical composition of zirconia corundum stable, with good crystal quality, tough texture, dense structure, and high strength, meeting the quality requirements of advanced abrasives and refractory materials.
Easy to operate: Equipped with programmable controllers and other automation control systems, it can achieve automation of electrode lifting, tilting, and other operations, reduce labor intensity, and improve the accuracy and stability of operations.
Good environmental performance: Some zirconia alumina electric arc furnace equipment is equipped with specialized exhaust gas treatment devices, such as installing filter tubes, to filter and treat harmful gases generated by heating, reducing pollution to the environment and harm to the health of workers.
