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.
