Alignment Device Design for 2800mm Medium and Thick Plate in Hot Rolling Line.
Abstract
This design focuses on the alignment device for the 2800mm medium-thick plate hot rolling line. Medium-thick plates are important steel products for industrial applications, and the hot rolling process requires the use of alignment devices to ensure the shearing quality and conveying efficiency of the steel plates. This paper includes an overview of the production process, performance requirements, and application fields of medium-thick plates, as well as an analysis of the role, types, components, and current development status of alignment devices both domestically and internationally.In accordance with the specifications outlined in the task document, key data such as friction force, alignment thrust, and stroke are calculated to provide data support for subsequent design and verification. Starting from the analysis of functions and loads, the structure of the alignment rod components is designed, including the determination of cross-sectional dimensions and connection methods, and the stability, strength, and bolt strength of the components are verified.Additionally, the characteristics and types of hydraulic cylinders are introduced, followed by the selection of hydraulic cylinders and the design calculations for parameters such as cylinder inner diameter, wall thickness, rod diameter, and rod length. The connection form between the cylinder barrel and the cylinder head is determined to ensure its strength, sealing performance, and reliability.
Keywords: 2800mm medium - thick plate；alignment device；force and energy parameter calculation；structural design and check.
