Description

Technical Field

[0001] This utility model belongs to the technical field of iron and steel smelting equipment, and in particular relates to a spindle rod centering adjustment device. Background Technology

[0002] The slab continuous casting machine primarily uses qualified high-temperature molten steel smelted in a converter to continuously cast slabs with specific end face shapes and dimensions. Before casting begins, the dummy bar on the dummy bar storage device is moved to the roller conveyor and aligned. Then, the dummy bar is inserted from the fan-shaped section into the designated position inside the crystallizer, the dummy bar head is sealed, and the formed slab is pulled out through the dummy bar, completing the dummy bar removal process. During the dummy bar feeding process, the dummy bar becomes skewed, and this skew continues after entering the fan-shaped section, causing the dummy bar head to misalign with the lower opening of the crystallizer, preventing it from being fed into the crystallizer. It needs to be pulled out and adjusted again. The adjustment method involves using two jacks and manual alignment before entering the 14th segment of the fan-shaped section. This operation requires two people and takes about 15 minutes. Then, the dummy bar feeding operation is repeated for about 30 minutes, severely restricting the production rhythm and operating efficiency, resulting in wasted manpower and low operating efficiency.

During each ingot feeding operation, alignment is performed at the 2nd and 5th sections of the ingot guide rod, with the entire operation lasting no more than 100 seconds. During alignment, the hydraulic cylinders 5 on both sides of the roller conveyor actuate, pushing the pusher head 7 against the ingot guide rod, thus correcting any deviation in the rod's alignment. The rollers 8 reduce the friction between the pusher head 7 and the ingot guide rod. After replacing the ingot guide rod with a different specification, loosen the bolt assembly 15 and adjust the position of the movable base 2 by loosening and tightening the adjusting bolts to ensure the distance between the pushers 7 on both sides of the roller conveyor meets the requirements. After tightening the bolt assembly 15, fine adjustments are made by replacing the shims 9 with shims of different thicknesses.
