Description

Technical Field

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

[0002] 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. The dummy bar storage device is a continuous casting equipment that collects and stores the dummy bars separated from the billet and quickly moves them out of the roller table.

[0003] A patent with patent number CN219685571U discloses a continuous casting machine ingot rod storage device, including a fixed seat, the upper side wall of the fixed seat is fixedly connected to an arc storage plate through a bracket, and the upper side wall of the arc storage plate is slidably inserted with a plurality of ingot rod bodies, the upper side wall of the arc storage plate is provided with a plurality of arc-shaped insertion holes matching the plurality of ingot rod bodies, and the side wall of the arc storage plate is fixedly connected to a fixed cover, and the inner wall of the fixed cover is slidably fitted with a positioning plate.
