Multilayered sealing magazine type hot rolled plate strip steel coil yard

Abstract

The invention relates to a multilayered sealing magazine type hot rolled plate strip steel coil yard. The multilayered sealing magazine type hot rolled plate strip steel coil yard is characterized by comprising a multilayered deck type frame and steel plate sandwich walls, wherein the sealed steel plate sandwich walls are arranged on the periphery of the multilayered deck type frame; an air inlet and an air outlet are respectively formed in each steel plate sandwich wall and are opposite to each other; an inlet elevator is arranged at each inlet; an outlet elevator is arranged at each outlet; a water-cooling tube is coiled in each steel plate sandwich wall; more than two rotating type conveying chains are uniformly arranged on each deck; the rotating type conveying chains extend from inlet sides to outlet sides of the decks; and heads and tails of each two adjacent rotating type conveying chains are respectively connected with each other through walking beams. Compared with the prior art, the multilayered sealing magazine type hot rolled plate strip stele coil yard has the advantages that the steel coil storage quantity can be conveniently increased by a frame type multilayered design; steel coils are conveyed independently, so that quality defects such as turned edges are avoided; by a magazine type structure, the steel coils are fed and discharged orderly, pitches among the steel coils are guaranteed, and heat dissipation is benefited; and the water-cooling tubes in the partition walls recycle afterheat of the steel coils, and energy is saved.

Description

technical field [0001] The invention relates to the field of hot-rolled production, in particular to a multi-layer sealed magazine-type hot-rolled plate, strip, and coil warehouse. Background technique [0002] Hot rolling is the finished product production process with the largest output and the highest production efficiency in the field of steel production. Therefore, hot-rolled coils are prone to a backlog of products in the finished product warehouse due to large output and untimely delivery. Because the steel coils are round objects, it is difficult to stack them, and they will roll when they are laid down, causing potential safety hazards. Up to three layers can be stacked upright, but this will cause deformation of the edges of the steel plates, affecting product quality, and stacking too densely will also affect the heat dissipation rate of the steel coils. In addition, hot rolling is a large energy consumer. When the hot rolled steel coil is produced and enters the ...

Problems solved by technology

[0002] Hot rolling is the finished material production process with the largest output and the highest production efficiency in the field of iron and steel production. Therefore, hot-rolled coils are prone to a backlog of products in the finished product warehouse due to large output and untimely delivery.

Because the steel coils are round objects, it is difficult to stack them, and they will roll when they are laid down, causing safety hazards. Up to three layers can be stacked upright, but it will cause deformation of the steel plate edges and affect the product quality. Stacking too densely will also affect the heat dissipation speed of the steel coils.

In addition, hot rolling is a large energy consumer. When the hot rolled steel coil is produced and enters the finished product warehouse, the temperature of the steel coil itself is 400-600 ℃, which contains huge heat energy. The heat gradually dissipates in the air, resulting in energy waste. A large amount of water vapor is generated on site, the production field of view is low, the visibility is poor, and the operation is difficult
