| Abstract: | The aged electric control device of main hoist DC motor was replaced during intermediate maintenance at BF4, Iron-making Subsidiary, Tiantie Group. Its control circuit was modified to achieve variable speed control of main hoist motor and eliminate the problem of small start torque of right carriage’s charging motor during commissioning course. More than one year’s running of the electric control device showed few failures and the charging demand of blast furnace was met. |
