Technical description
Function
The
sintering oven
is used to fire sinterable ceramics.
The product to be sintered is placed in the sintering dish and set on the
support discs. The electrically powered oven door closes and the heat-up
process starts after entering the heating parameters and pressing the Start/
Stop button.
Once the heating program has ended and the
sintering oven
has cooled
down, the oven door opens and the finished product can be removed.
Heating chamber
The product is sintered in the heating chamber. This consists of two different
ceramic insulation layers and is operated using MoSi
2
heating elements. The
outer insulating layer is designed for temperatures up to 1200 °C; the inner
layer for temperatures up to 1700 °C.
Oven door
The oven door consists of a three-part ceramic door panel. A safety switch
disconnects the heating current as soon as the oven door is opened.
A slip clutch used in the drive mechanism prevents too high a contact pres-
sure between the oven door and heating chamber.
Oven housing
The oven housing consists of steel plate coated with plastic on both the
inside and the outside.
Program controller
The program controller
has a finishing-time setting that can be used to spec
-
ify a day and time for the program to finish. The switch-on time is calculated
automatically so that the heating process is stopped at the required time and
the sintered item can be removed.
Operating parameters and heating programs are stored in a non-volatile
memory and are retained even if the power supply fails.
The set target temperature is maintained within an accuracy of ± 1 °C.
A temperature sensor integrated into the heating chamber measures the
temperature of the chamber close to the product.
A thermocouple fail-safe prevents the
sintering oven
from overheating if
the temperature sensor becomes defective.
