| In the rebuiding of charging system of 2000m~3 blast furnace at Handan Iron and Steel Group Company, the original analogue drive system was replaced by a fully digital DC drive system.

After this drive system is used in production,the utilization coefficient of blast furnace reaches 2.0 and the charging system works reliabily. |
