Kiln alignment, kiln loading, kiln crank, and diametrical clearance (creep) and other factors affect the ovality of the kiln: Tire ovality is determined by the design of the tire (thickness and width) at the pier. Shell ovality refers to tire ovality that transfers to the shell plate. Thus, shell ovality is never lower than tire ovality.
Shell flex (ovality) remains a primary indicator of mechanical stability of refractories. Additionally, it has significant synergy with mechanical aspects of kiln failure modes. Similarly, hot kiln alignment has become a cornerstone of identifying mechanical deficiencies in rotary kilns as well fundemental to short and long

SHELL OVALITY ASSESSMENT All kiln maintenance service providers measure shell ovality in the process of evaluating the alignment of kilns. The information is usually put to limited use however. The rationale for aligning a kiln axis, properly understood, is to optimize ovality distribution over the length of the kiln.
The sudden temperature change decrease or increase the value of creep. It is strongly recommended to keep shell temperature stable around whole kiln shell circumference. There are many problems that can be caused by excessive tire migration: When creep is bigger – wear accelerates; Ovality of shell is higher.
Hot kiln alignment; ... This is important to establish and minimize the stresses on the kiln shell, uneven loads between the supports and the supporting components. Especially this is also very much important for maximizing refractory life and coating stability as the shell flexing would be high if the misalignment exists. ... Shell ovality ...
Shell flexing or distortion on a straight kiln is measurably higher near the burning zone than at the cold end. Refractory life can be maximized by lowering the shell shear load at …
high localised shell flexing associated with ovality. Shell flexing is, in other words, spread over a large surface where it is negligible on a per unit area basis. Stability will be increased because the maximum ovality on the kiln is decreased. A lowered maximum ovality means that the kiln will run longer before brick loss occurs.

The Ovality Sensor consists of a Deflection Plate, which will be attached with heat resistant magnets to the kiln shell close to a tire. Due to the strong magnetic connection, the deflection in the Deflection Plate follows the deflection of the kiln shell below. Strain gauges are measuring the deflection in the Deflection Plate.
