摘要： PROBLEM TO BE SOLVED: To prevent any overload in and operation stop of a motor for agitation, and impossible desulfurization due to the load torque exceeding the initial estimation in the desulfurization method of the hot metal for removing sulfur content from the hot metal in a vessel such as a hot metal ladle. SOLUTION: The operation stop caused by the overload of the motor is prevented by monitoring the overload residual value R estimated from the load current value of the motor 16, and controlling the rotation of the motor so that the overload residual value is not below the allowable value R0.
