Description

Technical Field

[0001] The utility model relates to the technical field of tempering heat treatment, in particular to a high-temperature uniformity cold rolling roller tempering heat treatment device. Background Art

[0002] Cold rolling rolls, also known as cold rolling mill work rolls, are the main components of the cold rolling mill and are directly involved in the metal processing process. They are mainly used for rolling plates and strips and are indispensable tools in the cold rolling process. Cold rolling rolls are usually made of high-hardness materials, such as forged steel, and have sufficient strength and uniform surface quality to withstand extremely high rolling forces, ensure sufficient wear resistance, and meet the precision requirements of rolled materials. However, during the quenching process, cold rolling rolls will produce large residual stresses due to rapid cooling. If these residual stresses are not eliminated in time, they may cause deformation, cracking and other problems in the rolls during use. The tempering operation affects the service life of the roll and the quality of the rolled products. The tempering operation is carried out by heating and keeping warm at a certain temperature to rearrange the atoms and molecules inside the roll, thereby eliminating or reducing the residual stress caused by quenching and improving the dimensional stability and performance of the roll. Although the hardness of the cold-rolled roll after quenching is higher, its toughness is relatively poor. Through the tempering operation, the toughness of the roll can be improved while maintaining a certain hardness, so that the roll can better resist impact and fatigue during use and extend its service life. The choice of tempering temperature and time has an important influence on the hardness and toughness of the roll. Generally speaking, tempering The higher the temperature and the longer the time, the lower the hardness of the roll and the better the toughness. Therefore, it is necessary to select appropriate tempering parameters according to the specific rolling process and roll material. The tempering operation can also make the internal structure of the roll more stable, reduce the structural changes caused by temperature changes, and improve the wear resistance and corrosion resistance of the roll. Through reasonable tempering treatment, the cold rolling roll can achieve the best balance in hardness, toughness, wear resistance, crack resistance, etc., and improve the comprehensive performance and service life of the roll. In the current market, most tempering equipment overemphasizes the thermal insulation performance in design, resulting in its closed hatch being constructed quite thick. This feature directly affects the overall flexibility of the equipment. Specifically, the supporting lifting mechanism appears to be bulky and lacks smoothness in operation, which brings unnecessary physical burden and inconvenience to users. In addition, when placing workpieces such as roll-type profiles, the fixing process is complicated and cumbersome, which not only takes a long time, but also significantly reduces work efficiency and ease of use. In summary, the existing tempering equipment still has a lot of room for improvement in improving user experience and operational efficiency. For the above problems, there may already be technical means to solve them in the existing technology, but this case intends to provide an alternative or replacement technical solution. Utility Model Content

[0007] Preferably, the roller body placement rotating structure comprises: a roller body spinning motor, a spinning support platform, a pair of telescopic gas rods, a pair of fitting clamping blocks and a front end support bracket;
