Dummy centering device for continuous casting sheet billet

Abstract

The invention discloses a dummy centering device for a continuous casting sheet billet, belongs to the technical field of continuous casting equipment and aims to solve the problems of imprecise centering and long operation time of the dummy centering of the continuous casting sheet billet. The technical scheme is that the device consists of a base, a motor, a speed reducer, a screw rod, a screw nut, a tailstock spindle, a tailstock spindle sleeve and a tailstock ejector rod, wherein the motor is connected with the screw rod through the speed reducer; the screw nut is engaged with the screw rod; the tailstock spindle is arranged in the tailstock spindle sleeve; the screw nut is connected with the tailstock spindle; the tailstock ejector rod is arranged at the front end of the tailstock spindle; and four sets of the dummy centering devices are respectively arranged at the symmetrical positions on the sheet billet roller table at the raising part of a dummy rod. The device is characterized in that four sets of the dummy centering devices are respectively arranged at the symmetrical positions on the sheet billet roller table to realize the linkage of the four sets of the dummy centering devices, achieve the once precise positioning of the dummy rod opposite to different positions of the roller table and reduce the time of repeat regulation. The device has the advantages of simplestructure, convenient use, precise regulation, quickness and convenient maintenance.

Description

technical field [0001] The invention relates to a slab dummy centering device for a continuous casting machine in the metallurgical industry, and belongs to the technical field of continuous casting equipment. Background technique [0002] With the development of the iron and steel metallurgy industry, the important role of continuous casting in product upgrading, technical transformation and high-efficiency production has become increasingly obvious, especially the high-efficiency of continuous casting has played an important role. The high efficiency of continuous casting is mainly manifested in: high caster operating rate, high stand-alone production capacity, high casting speed and high number of continuous casting furnaces. However, there are still some problems in the production organization process of conventional continuous casting machines, which affect the high-efficiency implementation of continuous casting. Dummy ingot greatly prolongs the preparation time for c...

Problems solved by technology

However, since the claw device adopts unilateral operation, it can only be adjusted in one direction (it can only be pushed forward but not pulled backward). Once it is pushed over the head, it needs to be lifted by the hoist again and then re-centered. Repeated customization happens from time to time; On the other hand, the claw device is operated by claws. Due to the poor precision, the centering accuracy is reduced, and the dummy spindle is re-installed from time to time.

Due to the shortcomings of this kind of claw device, such as huge equipment, low accuracy and precision, and difficult operation, it is limited to continue to be widely used.
