A slab segment and a slab segment replacement system

Abstract

The invention provides a slab segment and a slab segment replacement system. The slab segment replacement system comprises an overhead crane, wherein the lower end of the overhead crane is connected with lifting appliances, and a guide rail is fixed to the lower end of a casting table. The lifting appliances include a long lifting appliance and a short lifting appliance, the two sides of the long lifting appliance and the two sides of the short lifting appliance are provided with first guide wheels and second guide wheels respectively, and the first guide wheels and the second guide wheels are symmetrical, are arranged evenly and perform reciprocating motion on the guide rail. A first pin hole penetrating through the lateral sides of the replacement guide rail is formed in the guide rail, and a first hinge pin matched with the pin hole is arranged in the pin hole. The slab segment replacement system is composed of the overhead crane, the long lifting appliance, the short lifting appliance and the guide rail, the long lifting appliance and the short lifting appliance are used at different times when the slab segment replacement system is used, and the space distance required by replacement of the slab segment is shortened. The distance between the casting table and the upper limit of a hook of the overhead crane is shortened, so that investment is reduced, and resources are saved. In addition, slab knockout difficulty of a large new-built slab caster in an old factory building is reduced.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a slab segment and a slab segment replacement system. Background technique [0002] At present, as the thickness of the final plate product continues to increase, the slab needs to meet a certain thickness. With the increase in the thickness of the slab, the main radius of the continuous casting machine and the casting stream guiding equipment will also increase. When the segment is replaced When the upward pumping method is adopted, the distance between the pouring platform and the upper limit of the crane hook becomes the main factor restricting the smooth replacement of the sector. For the new factory building, in order to ensure the normal replacement height space of the continuous casting machine segment and the smooth discharge of the billet, the height of the factory building and the crane height must be increased, which increases the investment in the factory building and wastes...

AI Technical Summary

Problems solved by technology

For the new factory building, in order to ensure the normal replacement height space of the continuous casting machine segment and the smooth discharge of the billet, the height of the factory building and the crane height must be increased, which increases the investment in the factory building and wastes resources; for the existing factory building, The height of the factory building is constant, and the upper limit elevation of the crane hook of the factory building is constant. In order to ensure the height space for the normal replacement of the continuous casting machine segment, the elevation of the pouring platform and the billet surface must be reduced. With the reduction of the billet surface, the foundation of the continuous casting machine The amount of construction and investment costs increase, wasting resources, and also increases the difficulty of casting billets
