Description

Technical Field

[0001] This utility model belongs to the field of auxiliary equipment, and in particular relates to an adjustable inlet guide for a finishing mill. Background Technology

[0002] Hot-rolled steel sections are widely used in civil buildings, industrial buildings, bridge construction, petroleum industry, high-rise buildings, underground railways, mine tunnels, and industrial steel structures due to their excellent mechanical properties. With the rapid development of my country's economy, the demand for steel section output and quality is increasing daily, placing higher requirements on steel section production lines. Along with the widespread application of H-beams in various fields, H-beam rolling mills are also gradually developing and improving, evolving from the original archway-type universal rolling mill to the current connecting plate type universal rolling mill, short stress line universal rolling mill, and prestressed universal rolling mill. These mills have higher rigidity than the previous universal rolling mills and can roll H-beams with better mechanical properties and greater economic efficiency.

[0003] In section steel production, the device installed before and after the roll pass to assist the workpiece in accurately and stably entering and exiting the pass in a predetermined direction and state is called a guide device. For rolling section steel of any cross-sectional shape, guide devices are installed at the inlet and outlet of almost all roll passes. Their main function is to ensure that the workpiece is rolled in the pass in a certain order and in the correct state, reducing rolling accidents, ensuring personal and equipment safety, and improving the working conditions of the rolls, workpieces, and guides themselves. Proper design and adjustment of the guide device is a crucial aspect of section steel production, compensating for deficiencies in the roll pass design. Therefore, the quality of the guide device design and installation has a significant impact on product yield and quality, making it a vital part of section steel production. Utility Model Content
