  • Application of iSVG Device in Metallurgical Industry
    Application of iSVG Device in Metallurgical Industry
    Taiyuan Iron & Steel (Group) Co., Ltd. Refractory Materials Co., Ltd. (hereinafter referred to as the company) is the subordinate refractory professional production plant of Taiyuan Iron and Steel (Group) Co., Ltd and one of the large-scale production enterprises of refractory industry in China. It was founded in 1931 with a floor area of 220,000 square meters, construction area of 105,000 square meters, the total equipment weight of 7423 tons, the annual sales income is stabilized at 50 million yuan.
  • Application of High Voltage Variable Frequency Speed Regulating System in Desulphurization Fan
    Application of High Voltage Variable Frequency Speed Regulating System in Desulphurization Fan
    The induced draft fan of desulfurization system in the new project of a zinc smelting enterprise in Yunnan is driven by a 6kV / 800kW high-voltage motor, the load has a very important role in the process, once the problem occurs, it will cause environmental pollution, due to the numerous dust on site, So the stability requirements to the inverter are higher, in the operation process, the wind pressure is needed to be adjusted in real time according to the working conditions. Taking the energy saving, stability and other factors into account, the company finally selects our company’s inverter for the project construction.
  • Application of High Voltage Variable Frequency Speed Regulation System in High Power Synchronous Motor
    Application of High Voltage Variable Frequency Speed Regulation System in High Power Synchronous Motor
    A steel plant of HBIS Group has two sintering machines, the main sintering exhaust fan is driven by a 10kV / 7100kW synchronous motor. The enterprise initially uses water resistance cabinet to start the motor in the way of asynchronous start, if the excitation system is not accurately controlled in starting, it will cause out of step and affect the production, and the large start impact current will produce torque ripple, causing damage to the motor. In addition, it adopts windshield to adjust the air volume with serious energy waste.
  • Application of INVT CHV190 Inverter in Metallurgical Crane
    Application of INVT CHV190 Inverter in Metallurgical Crane
    The bridge crane of rolling mill plant generally includes five major institutions: the main lift, deputy lift, cart, the main car, deputy car body. As the crane's bit load characteristics have more stringent safety requirements, the large inertia, short-term work, frequent starting brake operation of agencies has more harsh requirements to the speed adjusting program, Over the past decade, the mature of direct torque control theory and the successful manufacture of high-power vector inverter result in the successful application of frequency control technology in the crane. This paper describes the application of INVT CHV190 series inverter in the steel plant 125 / 32t tons metallurgical crane.
