CONVEYER FOR ROLLING MILL AND CONTROL METHOD THEREOF

PURPOSE: A transfer device for a rolling mill and a control method thereof are provided to easily radiate heat transferred from an object to a transfer roller by increasing the contact area and time of the transfer roller and cooling water. CONSTITUTION: A transfer device for a rolling mill comprises a transfer roller(10), a water tank(30), a water supply unit(32), a water drain unit(34), a temperature sensor, and a control unit. The transfer roller transfers an object and is submerged in cooling water stored in the water tank. The water supply unit supplies cooling water to the water tank. The water drain unit discharges the cooling water from the water tank to the outside. The temperature sensor senses the temperature of the cooling water stored in the water tank. The control unit confirms whether the water supply unit and the water drain unit are operated or not depending on the sensed signal from the temperature sensor.
