Description

Technical Field

[0001] The utility model relates to the technical field of dummy rods, in particular to a guiding device of a dummy rod for continuous casting machine production. Background Art

[0002] Continuous casting machines are generally used in the process of continuous steel casting. The dummy bar is one of the important devices for continuous steel casting and ironmaking. The dummy bar consists of a dummy head, a transition piece and a rod body. Before pouring, the dummy head and part of the transition piece enter the crystallizer to form the movable "inner bottom" of the crystallizer. After the pouring begins, the molten steel solidifies and condenses with the dummy head. The dummy bar is pulled by the straightening machine to continuously pull the billet out of the crystallizer until the dummy head passes through the rear of the straightening machine and is separated from the billet and enters the dummy bar storage device.

[0003] During the transportation of the current dummy rod, the dummy rod often hits the guide rotating roller, thereby generating a large impact force, causing damage to the dummy rod; and the dummy rod may deviate. If not corrected in time, the dummy rod may collide too much with the crystallizer. Utility Model Content

By observing the angle scale line 76 on the deviation observation disk 75, the rotation position of the dummy rod 8 can be observed. By further adjusting the rotating handle 73, the deviation of the dummy rod 8 during the left and right guiding process can be reduced.
