Technical description
Intended use
The
Tabeo sintering oven
is a high-temperature oven for commercial ap -
plication in dental laboratories and may be used only for sintering sinterable
chromium cobalt using original spare parts.
At a total output >1kW, no limit values for the harmonics apply.
Notice
The protection of persons can no longer be ensured and no liability can
be assumed for damage that is caused by misuse, incorrect operation,
incorrect connections or improper maintenance/repair work carried out
by untrained personnel. All warranty services are also excluded in such
cases.
The use of spare and wearing parts that have not been procured from the
manufacturer will render the approval and guarantee of the sintering oven
null and void.
Potential misuse
y
Operation by untrained and insufficiently qualified personnel.
y
Use of products that have not been approved by the manufacturer.
y
Use of replacement parts that have not been approved by the manu -
facturer.
y
Any use not in accordance with the declaration of conformity.
y
Technical modifications to and conversions of the unit that have not
been approved by the manufacturer.
Sintering with argon
The sintering of NEM is possible only in an oxygen-reduced atmosphere.
This is attained by using argon. Argon is an inert gas in a compressed gas
bottle. Always use argon bottles with a pressure gauge as well as a pressure
reducer. The purity of the argon must be at least 4.6= 99.996 % vol. During
the sintering process the argon flow is 1 l/min.
Determining the filling level of the compressed gas bottle:
The filling level of the compressed gas can be determined at the pressure
gauge. A new argon compressed gas bottle is filled with 200 bar.
Calculation:
A 50 litre compressed gas bottle of argon with a filling pressure of 200 bar
contains approx. 10,000 litres of argon.
At a flow of 1 l/min, the consumption per sintering process is approx. 270
litres.
With a 50 litre compressed gas bottle, approx. 35 NEM sintering processes
are possible.
