Fixed tray stacking type cooling bed

Abstract

The invention relate to a cooling bed, which is used for the cooling after a medium plate heat treating production line is heated. A fixed tray stacking type cooling bed is characterized in that: the fixed tray stacking type cooling bed comprises a first fixed stack, a lifting stack, a second fixed stack and heat exchanging devices; the first fixed stack, the lifting stack and the second fixed stack are arranged sequentially from a material feeding end to a material discharging end; the left side and the right side of the first fixed stack, the lifting stack and the second fixed stack are respectively provided with the heat exchanging devices; the second fixed stack has the same structure with the first fixed stack; the first fixed stack comprising a supporting bracket, a fixed tray and aroller way conveying device; the lift stack comprises a guide frame, a lifting frame, a lifting mechanism, a fixed tray and a roller way conveying device. The cooling bed in the invention has the characteristics that the occupied area is small, the space using ratio is high and the sensible heat can be recovered.

Description

technical field [0001] The invention relates to a cooling bed, which is used for cooling after heating in a medium-thick plate heat treatment production line. Background technique [0002] According to the layout of the rolling process line, the cooling bed equipment is mainly used for slow and natural cooling of the rolled steel plate online. At present, there are mainly four structural types of cooling beds at home and abroad, which are: claw cooling bed, carrying chain cooling bed, stepping cooling bed and rolling plate cooling bed, and their characteristics are as follows: [0003] (1) Pull claw type cooling bed [0004] The claw-type cooling bed uses rollers or rails to support the steel plate, and uses a chain-type claw or a wire rope trolley to drive the steel plate to move laterally. For many years, the cooling bed on the medium and thick plate production line has adopted this structure. This kind of cooling bed has simple structure and low price, but the lower su...

AI Technical Summary

Problems solved by technology

This kind of cooling bed has the advantages of no scratch on the lower surface of the steel plate, good heat dissipation, high cooling efficiency, and easy operation, but the structure is more complicated, the floor area is large, and the one-time investment is large.

[0011] In summary, it can be seen that the above four types of medium and thick plate cooling beds generally have the characteristics of large floor area, insufficient recovery of sensible heat of the steel plate, large thermal pollution to the environment, oxidation phenomenon, poor surface quality and plate shape quality, etc.
