Application purpose of roller:
Users Manual
¨ Please spray a coat of
protective slurry with main components of zirconium
silicate, fine quality corundum and kaolin before using
the roller. This slurry
can prevent the
surface of the ceramic roller from being chemically
corrupted and reduce the forming of cohesive stuff on the
surface of the ceramic roller.
¨ Please place the roller
on the top of the kiln in the sintering zone (about 120 oC)
to preheating and drying the rollers before inserting them
into the kiln and make sure that it will last at least 12
hours.
¨ Please note that the
process for inserting the roller into the kiln shall be
finished as quickly as possible in order to shorten the
time for keeping the roller heated without rotating.
¨ Please keep the roller
rotating when they are loaded. Abstain from power failure.
¨ Generally, the roller
should be taken out of the kiln after it has been used in
the kiln for 4-6 weeks and the cohesive stuff on its
surface should be ground with sand paper or special tools
for cleaning the roller. Avoid using any other hard tools.
If the cohesive stuff on the roller gathers a lot, the
roller should be cleaned more often.
¨ Please spray the
protective coat again after the roller is cleaned, and
repeat the above-mentioned operation rules.
¨
If it is necessary to
move the hot roller to another place after it is taken out
of the kiln, please hold the roller using
heat-insulating cotton or glove and keep it
vertical in transportation. Avoid holding the roller
aslant or horizontally to prevent the hot roller from
being bent.
¨ Avoid contacting the hot
ceramic roller with cold metal tools.
¨ Avoid leaning the hot
ceramic roller against the kiln.
¨ Please place the roller
on theheat-insulating
carpet horizontally after it is taken out of the
kiln and cover it with heat-insulating cotton to cool it
down slowly.
¨ Avoid the corrosion of
boron, lead and alkali metal element to the surface of the
ceramic roller.
¨ Avoid knocking the
ceramic roller.
¨ Avoid excessive
temperature gradient in the roller.
Notes: Proper operation of the ceramic roller
according to instructions shall help you to prolong the
life of ceramic roller and
produce good quality ceramic tiles successfully.
