Ever wonder what excessive shell ovality could be telling you about your unit? 👀
As your unit rotates, the shell naturally flexes. A little flexing is normal, but too much can put additional stress on the shell over time.
That repeated flexing can contribute to:
• Shell fatigue
• Distortion
• Cracks
But shell ovality can also offer insight into your refractory. Changes in shell flexing may indicate areas where the refractory has deteriorated or shifted.
That’s why monitoring and trending shell ovality over time is so important. Keeping an eye on changes can help you spot developing issues before they become much bigger, and more expensive, problems.
