Mounting - SKF EAZ Mode D'emploi

avoid damages in the inner surface of the EAZ coil.
Be aware of the hot surfaces and use the supplied
protection gloves.
J. Once the ring is withdrawn from the roll neck,
the heated ring must be immediately removed
from the induction heater. By doing this, the
risk of damaging the coil sleeve is reduced
and the duty cycle of the heater is signiicantly
increased.
K. If for any reason the circuit is to be interrupted
before the pre-determined heating setting is
over, press the STOP button on the GUI screen
or the OFF button on the induction heater. Only
in case of emergency you can switch off the
cabinet by using the main switch handle. Be
aware that in the last case the ring won't be
demagnetized.
L. If the ring cannot be withdrawn due to tilting
during the withdrawal, remove the EAZ coil
from over the ring and use a soft hammer to
correct the ring position and try to pull the ring
out again. Do not use metallic hammers or bars
as this might damage the bearing!
M. If the dismounting is anyhow unsuccessful,
remove the EAZ coil from over the ring and
wait until the ring and the roll neck has cooled
down before making another attempt. This will
ensure that the temperature difference between
neck and ring needed for dismounting can be
obtained. Compressed air or a fan may be used
to speed up the cooling process.

6.2 Mounting

A. Electrical induction heaters can also be used
for heating the rings during mounting. For this
purpose, place the ring in the bore of the heater.
B. Select the Mounting Mode on the User Interface
screen of the control cabinet.

C. Place the temperature probe on the ring. Set
the right temperature on the cabinet settings
if Temperature Mode is to be used or the right
heating time if Time Mode is to be used.
D. Once the right settings have been selected,
push the START button.
E. The ring and the EAZ coil should be at a close
distance from the roll neck where the ring will
be mounted. A short distance means a short
time to mount and therefore less time for the
hot ring to cool down.
F. Once the cabinet has reached the heating
settings, the ring will be automatically
demagnetized.
An audible signal will indicate that the user can
collect the hot ring to mount it.
G. Remove the temperature probe if used and
locate it on a safe surface on the EAZ coil. It is
very important to use heat resistant gloves for
this.
H. Mounting the hot ring on a cold roll neck
requires some practice. It is very important that
the hot ring is perfectly aligned with the roll
neck shaft, so it does not get stuck halfway. If
this happens, correcting the ring position with a
plastic hammer is a good option. Do not use a
steel hammer as this might damage the bearing
ring.
