Description

Technical Field

[0001] The utility model relates to the technical field of cold roller heat treatment equipment, in particular to a cold roller heat treatment device. Background Art

[0002] Cold rolling rolls are key equipment used in the cold rolling process. They generally refer to working rolls for cold rolling, which are used to roll plates and strips. Cold rolling rolls are complex components with a very hard surface to withstand extremely high rolling forces and ensure sufficient wear resistance to meet the precision requirements of the rolled materials. Cold rolling rolls are usually made of forged steel, and those that can be quenched to a high hardness are used as cold rolling rolls. In addition, cold rolling rolls also include support rolls that play a supporting role, but the support rolls are a self-contained system. Therefore, cold rolling rolls are often narrowly referred to as cold rolling working rolls. Cold rolling rolls need to withstand extremely high rolling forces and friction during operation, so they must have sufficient hardness and wear resistance. Through heat treatment, such as quenching and tempering, the surface of the roll can obtain high hardness, thereby improving its wear resistance and extending its service life. Heat treatment can effectively optimize the microstructure distribution of the roll, control the grain size, and thus improve its mechanical properties. For example, tempering treatment (quenching + high temperature tempering) can make the roll obtain tempered bainite structure. This kind of structure can be quickly transformed into uniform austenite under the short-time austenitization conditions of induction heating, while retaining some undissolved carbides to improve wear resistance. Heat treatment can also improve the stress state of the roll and reduce internal defects such as cracks and residual stress. Induction heating quenching is a surface heating technology that can make the roll obtain a hard surface while maintaining a tough core, which is beneficial to improving the impact toughness and fatigue strength of the roll. With the continuous development of rolling technology, the performance requirements for rolls are getting higher and higher. By adjusting the heat treatment process, cold rolls that meet different rolling conditions can be produced. For example, increasing the alloy composition of the roll, adopting new roll blank composite manufacturing technology, applying new roll heat treatment and processing technology, etc., can improve the performance and service life of the roll. The application of large-scale CNC machine tools, computer-controlled heating furnaces and quenching equipment can increase the manufacturing accuracy and surface uniformity of the roll, making it better adapted to the needs of high-end rolling mills.In summary, the purpose of heat treatment of cold rolling rolls is to improve their hardness and wear resistance, optimize tissue distribution, improve stress state, adapt to different rolling conditions, and improve manufacturing accuracy and surface uniformity, so as to ensure that the rolls can maintain stable performance and extend their service life during use. However, in the field of heat treatment processing of rolling rolls, existing heat treatment devices generally face the problems of complex and lengthy structures and cumbersome and non-intuitive operation procedures, which not only greatly increases the difficulty of use and reduces operating efficiency, but also significantly affects the user experience. More importantly, the heating and temperature rising effects of these devices during the heat treatment process are not satisfactory, and it is difficult to In order to fully meet the high requirements of the roller material for precise temperature control and uniform heating, thus limiting its wide application in roller processing, greatly weakening its practicality and market competitiveness, in view of this, it is particularly urgent to innovate and optimize the roller heat treatment technology. It is urgent to develop and design a new type of heat treatment device with a more streamlined structure, simple and fast operation, and significantly improved heating and heating effect, so as to achieve efficient and accurate heat treatment of the roller material, thereby improving the processing quality of the roller, extending its service life, and promoting technological progress and industrial upgrading of the entire rolling industry, such as "Utility Model CN219409835U A cold rolling roller heat treatment device. The present invention relates to a cold rolling roller heat treatment device. The heating components are evenly distributed within the housing through a circular frame and vertical rods, and a heating wire is wound along a positioning wheel. When in use, the heating wire heats the interior. The heating wire wound outside the positioning wheel can evenly heat the internal area, so that the roller placed in the socket is evenly heated, greatly increasing the heating efficiency and enhancing practicality. The present invention also relates to a cold rolling roller heat treatment device. The lifting component is provided, and a hydraulic cylinder is used to control the lifting and lowering of the top cover, which facilitates the removal and placement of the rollers undergoing heat treatment, thereby improving simplicity. The present invention also relates to a cold rolling roller heat treatment device. The circulation component is provided. When the rollers are heated, the motor is started, and the motor drives the power shaft to rotate, thereby driving the fan blades to rotate slowly, accelerating the circulation of heat within the housing, thereby improving the heating efficiency.
