Description

Technical Field

[0001] The utility model relates to the technical field of rolling rolls, in particular to a rolling roll with wear resistance and corrosion resistance. Background Technique

[0002] The rolling roll is the main working part and tool for continuously plastically deforming metals on a rolling mill. The rolling roll mainly consists of three parts: the roll body, the roll neck, and the shaft head. The roll body is the middle part of the rolling roll that actually participates in rolling metals, and it has a smooth cylindrical or grooved surface. The main function of the rolling roll is to continuously plastically deform metals.

[0003] The rolling roll is one of the indispensable tools in industries such as iron and steel smelting and non-ferrous metal processing. Since it is usually a fixed structure as a whole, when the roll body is worn after long-term use and needs to be replaced as a whole, if the wear degree of the roll neck and the shaft head is relatively light, replacing them together will cause a certain degree of waste of resources. Therefore, in view of the above problems, a rolling roll with wear resistance and corrosion resistance is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rolling roll with wear resistance and corrosion resistance to solve the problem of waste of resources caused by replacing the whole rolling roll after severe wear of the roll body.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0026] Working process: When the wear-resistant and corrosion-resistant rolling roll is in use, first install the rolling roll body 1 at a suitable position of the rolling mill. During the use process, the metal at the rolling mill is processed by the rotation of the roll body 101. Due to the repeated friction between the roll body 101 and the metal, after long-term use, the surface of the roll body 101 is severely worn. At this time, replacement is required. The user disassembles the entire rolling roll body 1 from the rolling mill, and then holds the nut 8 and rotates it in the loosening direction until it is removed. Then, the moving ring 5 is moved and removed from the left side of the rolling roll body 1. At this time, the entire roll body 101 can be moved to the left and then removed as a whole. Align the positioning groove 3 of the new roll body 101 with the positioning block 2 arranged on the outer side of the roll neck 102, and align the through hole of the roll body 101 with the fixing rod 6, and move the roll body 101 to the right until it is in close fit with the fixing ring 4. At this time, the threaded rod 7 is exposed. Pass the through hole of the moving ring 5 through the threaded rod 7, and then insert the nut 8 into the threaded rod 7 and rotate it in the reverse direction until it is tightened to fix the moving ring 5, so as to effectively fix the replaced roll body 101. Through the positioning device and fixing structure provided for the rolling roll body 1, the roll body 101 can be replaced separately after severe wear. Compared with the overall replacement in the prior art, it saves more resources.
