Development of rolling method by cross roll mill.

Fault Diagnosis of Roll Shape under the Speed Change in Hot Rolling Mill

The metal processing system usually consists of various components such like motors, work rolls, backup rolls, idle rolls, sensors, etc. Even a simple fault in a single component in the system may cause a serious damage on the final product. It is therefore necessary to diagnose the faults of the components to detect and prevent system failure. Especially, the defects in a work roll are critica...

Modeling of thin strip profile during cold rolling on roll crossing and shifting mill

Strip profile control in cold rolling of thin strip is a difficult and challenge problem found in industry. Currently using the novel type of strip rolling mill, such as the work roll crossing and shifting is the one of the main methods to control the strip profile quality in cold rolling. In this paper, 3-D finite element simulation models of the thin strip profile in cold rolling for the work...

Stiffness analysis method of rolling mill based on process data

Idea of the virtual rolling mill laboratory

Laboratory tests are crucial in education and training of engineers. Experimental equipment and process simulators are extremely expensive. It is not possible and justified economically to build such laboratories, for educational purposes, in large number of schools. On the other hand, education and training based on video films, etc., is not adequate and personal contact of students with a pro...

Online Eccentricity Monitoring of Seamless Tubes in Cross-Roll Piercing Mill

Wall-thickness eccentricity is a major dimensional deviation problem in seamless steel tube production. Although eccentricity is mainly caused by abnormal process conditions in the cross-roll piercing mill, most seamless tube plants lack the monitoring at the hot piercing stage but only inspect the quality of finished tubes using ultrasonic testing (UT) at the end of all manufacturing processes...
