Steel - Slewing Ring for Blast Furnace
History
A major steel mill had to replace a Slewing Ring bearing for its blast furnace. The resulting downtime would have caused significant loss in production if the original design had been used. NSK was approached to determine if there was an alternative that would reduce the downtime and lost production.
Corrective Measures
NSK worked with the mill to design a solution by splitting the bearing and installing it with-out removing the equipment on top of the blast furnace. This allowed the work to be done in 2 days instead of the original 7 day estimated, allowing for less downtime.
