Description
Technical Field
The invention relates to a rolling method of a tissue gradient plate, in particular to a non-uniform thickness rolling method of a metal plate with a tissue gradient structure, belonging to the technical field of metal plate rolling.
Background
With the rapid development of national economy and the increasing demand of service, the usage amount of metal plates is increasing year by year, and the metal plates need to have good wear resistance, corrosion resistance and other properties while meeting the strength requirement, so that obtaining high-performance metal plates through modification is one of the key points and hot points of long-term attention in the industry. If the microstructure is in gradient distribution, the plate is helped to show good ductility and realize strengthening under high-strength deformation conditions, so that excellent strength-ductility synergistic performance is obtained. Therefore, the process conditions are utilized to regulate and control the tissue morphology of the metal sheet so that the metal sheet is distributed in a gradient rule, and an important inspiration is provided for the modification research of the high-performance metal sheet.
The most widely adopted means for preparing the metal material tissue gradient structure at present are as follows: surface heat treatment, chemical vapor deposition, machining, electrodeposition, and the like. However, the gradient structure prepared by the traditional surface heat treatment method is difficult to realize quantitative and accurate control, and for metals with excellent heat conductivity such as steel, the controllability of the surface heat treatment method is poor, and an interface is often generated between the gradient structure and a substrate; the mechanical processing method can only act on the tissue gradient structure of a shallow layer on the surface of the material and has certain requirements on the plasticity of the material; the electrodeposition method needs a plurality of factors and has certain uncertainty in the regulation and control process, so that the obtained plate is easy to generate internal defects and difficult to obtain a tissue gradient plate with stable performance.
The prior structural gradient plate is mostly distributed along the plate thickness direction, and is difficult to meet the requirement of different service performance at different parts along the length direction. Rolling is one of the effective ways for forming and manufacturing plate products, and if the forming conditions are reasonably changed, the plate is in regular gradient distribution along the forming direction, which undoubtedly provides a new idea for the development of high-performance plate with gradient structure.

The method is characterized in that the geometric shape characteristics of the plate blank are designed and processed in advance before rolling, the thickness value of the plate blank changes regularly along the length direction, so that the deformation of each part of the plate blank is different during rolling, and the distribution rule of the structure changing in a gradient manner is regulated and controlled by the geometric shape characteristic design (the size of an inclination angle, the increase and decrease of one side or two sides and the like) of the plate blank along the length direction. The method can efficiently and massively form and manufacture the high-performance metal plate with the structure distributed in the gradient structure.
The invention is realized by the following technical scheme:

step three: preheating a metal plate blank in a heating furnace with a set temperature, and preserving heat for a period of time;
step four: adjusting the roller distance to a certain reduction (the roller distance is less than or equal to the minimum thickness of the metal plate); so as to ensure the surface flatness and quality of the rolled metal plate;
step five: after the plate blank is preheated, fixing the plate, and conveying the plate blank into a rolling mill by a push block under the drive of an automatic rolling device;
step six: and after rolling, cooling the plate to room temperature in air, correcting, and removing redundant waste materials on a plate shearing machine.

and secondly, under the conventional rolling condition, the stress state of the plate blank passing through the rollers along the length direction is kept unchanged. However, when the method is used for rolling, the stress state of the plate blank passing through the rollers is continuously changed, and the deformation of each part is changed along with the increase and decrease trend; continuously changing the deformation of each part along the rolling direction to ensure that the sizes of microscopic grains of the plate are in gradient regular change distribution, realizing quantitative regulation and control of the microstructure and the performance of the required parts in isomerous form, and realizing the improvement and the synergistic promotion of the toughness-ductility of the plate;
fourthly, the invention has the outstanding characteristics that the relation between the distance between the rollers and the size and direction change of the wedge-shaped angle of the plate blank can be adjusted, so that the gradient of the formed plate tissue is regulated and controlled to be continuously changed, natural transition is realized, no obvious boundary layer exists, and the comprehensive use performance of the plate is excellent;
fifthly, the geometric shape characteristics of the metal plate blank can be prefabricated as required, a rolled plate with the microstructure of different areas changing in a gradient way and the performance different is obtained, the regionalization, the functionalization and the liberalization of the microstructure and the performance of the plate product are customized as required, and the production requirement of flexible manufacturing is met;
and sixthly, due to the difference of the thicknesses of all parts of the prefabricated plate blank, the stress state and the deformation of the plate in the rolling process are in a gradient change trend. Therefore, the grain size distribution and the change rule are regulated and controlled, and the aeipathia that the strength and the ductility are compromised frequently existing in the process of modifying the metal plate in a deformation mode can be effectively solved;
