Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of metal composite plate preparation, and particularly relates to a multi-element metal composite plate continuous rolling equipment and method. BACKGROUND

[0002] In recent years, great achievements have been made in the fields of aviation and aerospace, national defense and military industry, transportation and equipment manufacturing in China, and the requirements for material performance have also been correspondingly improved to meet the ability to work under various different working conditions. The metal composite plate can greatly improve the performance of single metal material by firmly combining metals with different properties.

[0003] Currently, the preparation methods of metal composite plates mainly include explosion-rolling composite method, rolling composite method and casting-rolling composite method. Compared with the explosion-rolling composite method and the casting-rolling composite method, the rolling composite method has the advantages of high dimensional accuracy, uniform bonding, good continuity, high efficiency and energy saving. The rolling composite method can be divided into cold rolling and hot rolling. Compared with the cold rolling composite method, the composite plate prepared by the hot rolling composite method can alleviate the problem of thermal expansion difference and is more likely to achieve interfacial metallurgical bonding.

[0004] However, there are relatively few studies on the rolling of multi-element metal composite plates. For the rolling of four-layer metal composite plates, the four-layer metal plates are usually stacked together at one time, and then directly rolled at one time to obtain a composite metal plate. However, this method is prone to problems such as deformation incoordination between the metal plates, low interfacial bonding strength and the like, which makes it difficult to effectively prepare multi-element metal composite plates. In the hot rolling process, the plate is continuously in a high temperature state due to heating treatment and rolling process, which poses a great safety hazard.

[0005] Therefore, it is of great significance to realize the continuous and safe preparation of multi-element metal composite plates with high quality. SUMMARY

[0013] A method for continuous rolling of multi-metal composite plates includes the following steps: S1, Heating of one-pass rolled billet: The one-pass rolled billet obtained by assembling the second and third metal plates is placed on the first conveyor and sent into the No. 1 heating furnace for heating through the transfer module on the first conveyor. After heating is completed, the one-pass rolled billet is taken out through the transfer module and placed on the first conveyor. S2, One-pass rolling composite: The heated one-pass rolled billet is fed into the rolling module through the first and second conveyors to perform the first-pass rolling composite, and a one-pass rolled metal composite plate is obtained.

S4, Reversing: The second-pass rolled billet is transferred to the steering module. The steering worm gear box is raised above the third and fifth conveyors by the lifting hydraulic cylinder. The steering motor drives the steering worm to rotate the steering worm wheel, realizing a 180° turn of the roller conveyor, thereby rotating the second-pass rolled billet by 180°. Then, the steering worm gear box is lowered to the initial position by the lifting hydraulic cylinder, thus completing the reversing of the second-pass rolled billet. S5, preheating before second rolling: The second-pass rolled billet is conveyed to the fifth conveyor through the steering module. The second-pass rolled billet is sent into the No. 2 heating furnace for heating through the transfer module on the fifth conveyor. After heating is completed, the second-pass rolled billet is taken out through the transfer module on the fifth conveyor and placed on the fifth conveyor. S6, Two-pass rolling composite: The heated two-pass rolled billet is fed into the rolling module through the fifth conveyor, the turning module and the third conveyor to perform two-pass rolling composite to obtain the final multi-metal composite plate.

[0014] Compared with the prior art, the present invention has the following advantages: 1. This invention uses a mobile clamping module and an automatic identification welding module to complete automatic billet assembly in high-temperature environments, improving the autonomous operation rate of dangerous processes; effectively reducing the risk of high-temperature burns and mechanical trauma accidents, and ensuring high consistency of process parameters, further guaranteeing the stability of product performance, achieving a significant improvement in production efficiency and a fundamental improvement in production safety, and providing a brand-new technical solution for the large-scale industrial production of metal composite panels.

[0015] 2. This invention decomposes the traditional multi-metal rolling composite process into two optimized stages: the first stage achieves the rolling composite of the second and third metal layers, and the second stage completes the rolling composite of the first and fourth metal layers with a single-pass rolled metal composite plate. This process transforms the common two-layer dissimilar metal rolling composite into a four-layer dissimilar metal rolling composite, tightly bonding four metal materials with different properties into one. It cleverly avoids the inherent defects of single materials, fully integrates the advantages of each layer, and can precisely achieve the synergistic integration of multiple properties such as strength, corrosion resistance, thermal conductivity, and weight reduction. It not only achieves a perfect balance between strength and lightweight, but also significantly reduces material costs while ensuring excellent corrosion resistance, demonstrating strong performance adaptability and economic practicality.

[0016] 3. This invention first rolls the second and third metal plates, allowing them to fully deform and form a tight metallurgical bond, providing stable support for the subsequent outer layer. This reduces the required rolling force and lowers the load per rolling cycle. Furthermore, by adjusting the rolling parameters of the two rolling processes, such as temperature and reduction, the deformation requirements of different materials can be adapted in stages. The process of first rolling the second and third metal plates, and then bonding the first and fourth metal plates, balances bonding strength, deformation control, and production efficiency, making it particularly suitable for the production of dissimilar metal composites or sheet metal requiring high precision.

[0017] 4. This invention enables modular continuous production from multi-layer single-metal sheet blanks to multi-metal composite panels. By optimizing the production line layout, two consecutive rolling processes are completed on the same production line, improving production efficiency. Continuous production not only shortens the process flow and reduces energy consumption and material loss in intermediate stages, but also ensures product qualification rate, opening up new avenues for developing higher-performance metal composite materials.
