PURPOSE: A rotational position control system and method for a ladle turret are provided to reduce working hours by controlling the decelerating position of a ladle turret to accurately stop the ladle turret at the target position according to the weight of the ladle turret. CONSTITUTION: A rotational position control system for a ladle turret comprises a ladle turret(110), a PLC(Programmable Logic Controller,140), and a drive unit(120). The ladle turret has first and second ladles(114a,114b) and first and second arms(116a,116b). The PLC determines the speed of the ladle turret to turn the ladle turret from/to a first position to/from a second position. At the first position, molten steel is injected into the first or second ladle. At the second position, molten steel is discharged from the first or second ladle. The drive unit turns the ladle turret from/to the first position to/from the second position at the determined speed. The PLC also determines the decelerating position of the ladle turret so that the distance from the decelerating position to the stop position of the ladle turret is proportional to the weight of the ladle turret. |
