Description
technical field
[0001] The invention relates to the field of dummy head processing, and more specifically relates to a dummy head processing system and processing method. Background technique
[0002] A dummy bar consists of a dummy head, a transition piece and a shaft. Before pouring, the dummy head and some transition pieces enter the mold to form the movable "inner bottom" of the mold. After the pouring starts, the molten steel solidifies and condenses with the dummy head, and the dummy bar is pulled by the tension leveler. The slab is continuously pulled out from the crystallizer until the dummy head is separated from the slab through the back of the straightening machine and enters the dummy bar storage device. The cross-sectional size of the dummy head should be adapted to the cross-sectional size of the slab, and the shapes include dovetail groove type, I inverted cup type and hook type.
[0003] At present, the processing method of dummy head is full processing of ...
