Description

Technical Field

[0001] The utility model relates to the field of hot-rolled plate coiling machine use and steel coil production, in particular to a hot-rolled plate coil type control device. Background Art

[0002] The hot steel strip coming out of the last rolling mill of the finishing rolling mill is cooled to the set temperature through laminar flow and rolled into a steel strip coil by the coiler. The cooled steel strip coil is processed into steel plates, flat coils and longitudinally cut steel strip products through different finishing lines (flattening, straightening, cross-cutting or longitudinal cutting, inspection, weighing, packaging and marking, etc.) according to different needs of users. When the hot rolled coiler unloads the steel coil through the unloading trolley and places it on the fixed saddle at the coiler outlet, the coil shape will become flattened downward under the action of gravity, affecting the product technical indicators.

[0003] In particular, the flat coil phenomenon of cold-rolled bidirectional steel DP780 / DP980 and USIBOR1500 is prominent, and even causes the steel coils to be repaired or even scrapped. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the steel coil is easily repaired or even scrapped during the unloading process.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is as follows: the utility model is a hot-rolled plate coil shape control device, including a coil unloading trolley ground roller, a fixed saddle, a coil shape control ground roller, a coil transport trolley and a coil transport saddle, the coil unloading trolley ground roller is symmetrically arranged in two groups, the fixed saddle is located on one side of the coil unloading trolley ground roller, the fixed saddle is symmetrically arranged in two groups, the coil shape control ground roller is located on one side of the fixed saddle, the coil shape control ground roller is symmetrically arranged in two groups, the coil transport trolley is located below the coil shape control ground roller, and the coil transport saddle is arranged on the coil transport trolley.

[0006] Furthermore, the coil transport trolley is provided with a lifting structure, and the coil transport saddle is arranged on the lifting structure.

[0007] Preferably, the roll unloading trolley ground roller, the fixed saddle and the roll type control ground roller are fixed on the peripheral structure without affecting the movement of the roll transport trolley and the roll transport saddle.

[0008] Preferably, the roll unloading trolley ground roller and the roll type control ground roller are integral components, mainly composed of a mounting seat, a motor and a roller body.

[0009] The utility model has the following beneficial effects by adopting the above structure: the steel coil is transported to the coil shape control ground roller 3 by the fixed saddle 2 on the coil transport trolley, and the coil shape control ground roller 3 is driven by the hydraulic motor to rotate the steel coil 90° to improve the flatness of the coil, which can be repeated many times to achieve better results. The final inner diameter of the steel coil is controlled within the standard range of 715-780mm, and the flatness of the coil is ≤30mm, which has a considerable effect on improving the flatness of the steel coil.
