Dual-function cold-rolled steel coil off-line check station capable of uncoiling up and down

Abstract

The invention belongs to the technical field of steel coil inspection and relates to a dual-function cold-rolled steel coil off-line check station capable of uncoiling up and down. An uncoiling system is arranged on each of the upper layer and the lower layer of a double-layer flat laying type check station. The upper uncoiling system comprises an upper uncoiling guide plate, a first press roll, a pinch roll, a centering device and crosscut shears, and the lower uncoiling system comprises a lower uncoiling guide plate, a pinch roll and a centering device. Different uncoiling devices are arranged vertically in an uncoiling area of the double-layer flat laying type check station, the upper uncoiling system adopts an upper uncoiling mode while the lower uncoiling system adopts a lower uncoiling mode, and accordingly production rhythm can be accelerated, scratching of high-quality steel coils during uncoiling can be effectively prevented, and check requirements of various cold-rolled steel strips, especially high-end appliance sheets and automobile sheets, can be met. In addition, the dual-function cold-rolled steel coil off-line check station capable of uncoiling up and down has the advantages of compact structure, small occupied space, convenience in manufacturing, mounting, use and maintenance, low investment and the like.

Description

technical field [0001] The invention belongs to the technical field of steel ring inspection, in particular to a dual-function off-line inspection station for cold-rolled steel coils that can be uncoiled up and down, and is suitable for inspection of various cold-rolled steel strips. Background technique [0002] At present, the steel coil inspection station mostly adopts double-layer tiled upper uncoiling method for strip steel inspection. The inspection station is located on the exit side of the mill, parallel to the walking beam. When uncoiling, the steel coil trolley receives the steel coil from the coiler, rotates 180°, and then loads it on the uncoiler reel at the inspection station. Because ordinary steel coils are inspected by sampling, and the time interval between each coil is long, it can fully meet the inspection rhythm, while the steel coils for high-end home appliance panels and automobile panels have higher requirements on the surface of the steel coils, and ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a dual-function off-line inspection station for cold-rolled steel coils that can be uncoiled up and down, which overcomes the above-mentioned double-layer tiled upper uncoiling method with many steps in the inspection process and cumbersome operation, which accounts for about 1 / 3 of the inspection time. , it is difficult to meet the bottleneck problem of the inspection rhythm of high-end home appliance boards and automobile boards, and realizes compact structure, convenient operation and maintenance, and can meet the needs of multi-variety steel coil inspection
