Description

Technical Field

[0001] This utility model relates to the field of steel plate rough rolling technology, and in particular to a steel strip guiding device for steel plate rough rolling. Background Technology

[0002] Rough rolling of steel plates is a process in which several layers of steel plates are stacked together and hot-rolled into thin plates less than 2 mm thick using a two-roll mill. Currently, steel strips are rough rolled on rough rolling mills immediately after pickling. Because there is no guiding device for the steel strip at the exit of the rough rolling mill, the strip coils are very uneven after exiting the mill, resulting in very large tapered tolerances and misalignments, causing significant inconvenience to subsequent finishing rolling. Steel strip refers to a conveyor belt made of carbon steel, used as a traction and carrying component of belt conveyors, and also for bundling goods. It is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Steel strip, also known as strip steel, has a width of less than 1300 mm, and the length varies slightly depending on the size of each coil. Strip steel is generally supplied in coils and has advantages such as high dimensional accuracy, good surface quality, ease of processing, and material saving.

[0003] The steel strip after rough rolling of existing steel plates is prone to deviation during transportation, which greatly reduces the quality and efficiency of subsequent processing of the steel strip by the equipment, and cannot meet the needs of rough rolling of steel plates.

[0004] Therefore, we propose a steel strip guiding device for rough rolling of steel plates. Utility Model Content
