Analysis of Causes for Common Leveling Machine Faults

Equipment breakdowns are a normal part of operations. As long as the root cause is identified and resolved in a timely manner, the impact will be minimal. With this in mind, it is crucial to understand the common causes of machine failures so that we can handle them calmly. Therefore, today we will discuss some issues related to leveling machines.
For leveling machines, vibration marks and bubbles are particularly troublesome. There are many factors that can cause vibration marks, such as inaccurate zero-point calibration, improper depth of the leveling rolls, and equipment tilting. The most likely culprit, however, is an incorrect depth setting of the fine-leveling rolls. To address this, the residual stress of the strip steel must be continuously reduced to restore the normal shape of the sheet.
Bubbles may be caused by deoxidation issues in the leveling machine. For instance, if the molten steel is overheated and comes into contact with moisture in the air during secondary oxidation, bubbles will form. Therefore, the steel melting process must be strictly controlled to prevent the occurrence of bubbles.

When selecting a leveling machine, it is essential to choose high-quality products to avoid compromising subsequent operational performance.
