Hopewind researched and developed HD2000 Series Engineering-type Frequency Converter independently, which has been successfully applied on the 450m3 blast furnace winch equipment of an iron and steel factory in Siping City, Jilin Province on April 19, 2019. The project perfectly adapted to the requirements of high starting torque, strict starting and stopping speed and position, and high stability of the blast furnace winch equipment. Moreover, such frequency converter successfully passed the working condition measurements of coke and minerals under different loads (light load, heavy load and overload) and high/low speed operation. And in case of Mechanical band-brake device failure, it can timely protect the vehicle from sliding. Therefore, this produce is highly recognized by experts in the field. The successful implementation of this project indicates that Hopewind HD2000 Series Engineering-type Frequency Converter fully meets the requirements of high performance and high reliability for the application on blast furnace, as well as realizes a revolutionary breakthrough of domestic frequency converter in the key process of metallurgical smelting.
