The geometrical axis flexure of the rotary vessel shell is one of the most
serious operating problems for this kind of objects.
The flexure phenomenon is extremely dangerous.
At first sight - invisible, leads to the carrying system
overloads, causing e.g. excessive, cyclic loading on the contact of rings with
rollers. These excessive loads are the direct reason for rings and rollers'
raceways' cracks, and emergency damage of their shafts. Only in extreme cases,
the coat's flexure is visible in the form of the ring 'lifting' effect.
The rotary vessel coat's flexure can have
thermal (
temporal) or
mechanical (
stable) character, depending on the cause of its formation.
The only antidote on the permanent flexure of the rotary vessel
coat geometrical axis, as so far, has been its expensive mechanical repair.
Laborious cutting stages, regulation and again joint assembly
from the classical method can be eliminated by application of the alternative
thermal straightening solution.
