SD700K, the most compact variable speed drive ensures the production of 2 million iron tonnes per year.

Hanking Industrial Group Co., Ltd is heavily involved in the mining, metallurgy, electronics and precision manufacturing industries. The majority of work is carried out at the Fushun Huanwang plant, where the SD700K drive was installed to ensure the production of over 2 million iron tonnes per year. The iron is produced by direct reduction using blast furnace gas. The bucket hoist conveyor used to raise the loads to the furnaces is controlled by the SD700K, allowing the 220kW motor to move two buckets simultaneously. The SD700K, the most compact variable speed drive has the most advanced open-loop control and an initial torque of 110%, both ensuring a smooth response speed is achieved. This level of control is unique in the market and avoids the use of motor encoders in critical industrial applications with high levels of pollution.
