Ribbing in cold rolling of titanium strip is a common problem, and its reasons can be summarized in the following aspects:
1. Improper cold rolling process parameters: parameters such as rolling pressure, rolling speed and temperature in the cold rolling process have an important impact on the phenomenon of ribbing. If the rolling pressure is too high, the rolling speed is too fast or the temperature is not properly controlled, it will cause ribbing on the surface or inside of the titanium strip. Excessive rolling pressure may overstress the titanium strip, while excessive rolling speed may cause uneven deformation of the material.
2. Differences in material properties: The material properties of titanium strips may vary in different regions, such as grain size, structure, hardness, etc. If the properties of the material are not uniform, when it goes through the cold rolling process, the stress on different areas is not uniform, which will easily lead to the phenomenon of ribbing. The difference in material properties may be caused by improper preparation process, material batch variation or other factors.
3. Improper pre-process treatment: pre-process treatment also has a certain impact on cold-rolled ribbing. For example, if the annealing treatment of the titanium strip before processing is insufficient or there are defects, such as scale, oil stains, etc., it may cause ribbing during cold rolling. Appropriate pre-processing can improve the surface state and material properties of titanium strips and reduce the risk of ribbing.
4. Rolling mill equipment problems: cold rolling ribbing may also be related to rolling mill equipment. The state of the rolling mill equipment, the lubrication conditions of the rolling, and the geometric shape of the rolling may all have an impact on the ribbing phenomenon. Issues such as equipment wear, improper mill adjustment or insufficient lubrication can cause ribbing.
The problem of ribbing in cold rolling of titanium strip is a complex process problem, and the above factors need to be considered comprehensively to solve it, and adjusted and optimized according to specific conditions. In the production process, strictly controlling the cold rolling process parameters, strengthening the uniformity and quality control of materials, and maintaining the normal operation and maintenance of equipment are all important measures to reduce the problem of cold rolling beading. In addition, the process is regularly tested and optimized to improve the stability and controllability of the production process, which also helps to reduce the occurrence of cold rolling beading.
