Abstract
PURPOSE:To achieve safer and quicker roll changing operations by connecting the movable truck of the roll changing device of a rolling mill removably to the extension part of a moving device on the side opposing to the rolling mill side. CONSTITUTION:In changing an intermediate roll 2 and work roll 1, a movable truck 4 and the extension part 13 of a lower truck 12 are connected by means of a pin 7 and the lower truck 4 is guided to the roll containing position on a movable floor plate 14 along rails 8. The rolls 1, 2 are then pushed out onto the truck 4 by a push-out device not illustrated and the floor plate 14 is connected by means of a pin 15 to the end part of the truck 12 and is retreated to the specified position. To change a lower back roll 3, the pins 7, 15 are removed and the truck 12 is engaged with the roll 3. The roll 3 is then drawn out from the rolling mill, the stool 19 is placed, the truck is again moved to the direction of the rolling mill, the upper back roll 3 is superposed and is drawn to the outside, thereafter such operations are repeated to complete the exchanging of the old and new roll. The notch part of the pin hole of the floor plate 14 of ordinary methods is eliminated and the danger of the operators and the laboriousness of operations are eliminated.
