ABSTRACT
The baling lines are the last stage in the cellulose
production process. The cellulose coming from the dryer
is cut in rectangular sheets of preset dimensions and in the
baling lines are stacked, compacted, packed and tied for
transport. Composed of a series of automatized and functiondistinct
equipment, the baling lines presents various and
random failure modes, resulting in an elevated amount of
corrective maintenance and increased reestablishment and
production costs. The objective of this paper is to carry
reliability analysis using tools like RBD, LDA and RAM
aiming to determine the best maintenance strategy for the
equipment based on the reliability of its subsystems and
components. Upon realizing this work, it is verified that
the failure behaviors of components and subsystems of
the equipment that have the greatest contribution to the
downtime of lines are related to failures in the initial phase of
operation or shortly after maintenance interventions. Thus,
it was necessary to deepen the analysis using the fault tree
analysis tool (FTA) to identify the root causes and propose
actions to prevent failures.
