A slab pallet transportation system and process

Abstract

The invention discloses a plate blank tray transport system. The plate blank tray transport system is used for transporting plate blanks from a continuous casting workshop to a steel rolling workshop and comprises a plate blank transport tray (2) used for being loaded with the plate blanks, a front heavy load roller bed segment (3) and a rear heavy load roller bed segment (5), and the front heavy load roller bed segment (3) and the rear heavy load roller bed segment (5) are located underground and used for conveying the plate blank transport tray (2). The start end of the front heavy load roller bed segment (3) corresponds to the continuous casting workshop. The stop end of the rear heavy load roller bed segment (5) corresponds to the steel rolling workshop. A middle rotary table (4) is arranged at the joint of the front heavy load roller bed segment (3) and the rear heavy load roller bed segment (5). The plate blank transport tray (2) can be loaded with the plate blanks in the continuous casting workshop and conveyed to the steel rolling workshop through the front heavy load roller bed segment (3), the middle rotary table (4) and the rear heavy load roller bed segment (5). The invention further discloses a plate blank tray transport process. According to the plate blank tray transport system and process, energy saving and consumption reducing are achieved, the investment cost and running cost are low, and maintenance is facilitated.

Description

technical field [0001] The invention relates to the field of hot loading and hot delivery transportation in the iron and steel industry, in particular to a high-efficiency and energy-saving slab pallet transportation system and process from a continuous casting workshop to a steel rolling workshop. Background technique [0002] The traditional methods of slab transportation in the iron and steel industry from the continuous casting workshop to the rolling workshop mainly include flat car transportation and roller conveyor transportation. Among them, although the conveying method using the flat car is simple in equipment and low in investment, due to its very low work efficiency, it can neither realize hot loading and hot delivery of slabs, nor can it meet the production rhythm requirements of the hot rolling workshop. Therefore, in modern iron and steel enterprises Basically not used in production. [0003] The conveying method using roller table is the most common method b...

AI Technical Summary

Problems solved by technology

[0005] To sum up, there are many disadvantages in the existing slab roller conveying method: 1) The operating environment of the high-temperature slab roller is harsh, the heat radiation of the rolled piece has a great impact on the life of the roller motor and bearing, and the equipment failure rate is high ; 2) The hot-rolled slab has a large amount of oxide scale, inconvenient cleaning, and a large amount of equipment maintenance; 3) The conveying roller table adopts solid steel rollers, and the bearings need to be cooled by water. The investment and operation costs are very high; 4) The use of roller conveyors cannot fully and effectively design the logistics path and process equipment layout of the slab, and cannot meet the production process requirements to the greatest extent
