About: Tozato Measurements

The continuous casting machines’ oscillator may suffer interferences from many factors, therefore, leading to mold’s early wear. The relation between it and steel surface defects is huge, but when the root causes are properly handled, the problems is solved.

Tozato Measurements team performed a consultancy service at a customer that was experiencing a high rate of product downgrading. That being the case, it was noticed that the strands were presenting severe early wear problems in their molds as a result of frontal and lateral displacement errors.

The high friction level in continuous casting machine’s mold tubes strongly reduces their service life. A relation that can be proved by using appropriate tools to collect and analyze data.

It is rather common to have the copper molds with decreased service life due to early wear. The improper wear, among other reasons, is caused by intense friction between the product and the mold, therefore, resulting in trajectory errors offset caused by an oscillation table topographic unleveling.

After all, is there a straight relation between the oscillation table topographic leveling and the coper molds early wear? The study below will help you to understand how much these two factors are related.

During the continuous casting process, many factors may cause surface defects. However, two of them are very common and need special attention: oscillator’s trajectory errors and mold wear.

Nonetheless, it was not always possible to verify and prove the correlation between those two factors. With the advance of technology in oscillation monitoring, and in mold internal faces’ measurements, it was possible to prove this relation successfully. Find out more:
