Tensile Testing Machine High Temperature furnace 3-zone split type
These three-zone split furnaces are designed for ETM-D series
universal testing machine and HTC series creep testing machine.
The elements of the split furnaces have been designed to achieve
optimum performance and give the longest possible useful life. The
heating elements are individually wound on MULLITE half tube
sections, and provide three heat zones for excellent control of
temperature gradients and reliable continuous operation up to the
specified maximum temperature.
High performance multi-crystal mullite refractory fabrics
insulation is used to reduce heat losses and provide fast heat up
rate. The specimen is heated primarily through radiation.
The exterior finish is stainless steel. Adjustable stainless steel
latches keep the furnace sections locked together during tests and
facilitate opening and closing of the furnace.
Ceramic closures at top and bottom fit closely around the loading
bars and reduce heat loss at these points.
Each furnace has been designed for long life, good temperature
uniformity and safe operation.
Mounting brackets for furnace
Furnaces need to be firmly attached to the test system during use
but also readily moved to allow access to the specimen for
A variety of mountings are used depending on the furnace type and
design. Roller mounts are frequently used for slot-fronted
This part is useful to protect grips from heat diffusion from the
Pull rod and tension grips
Various design of pull rods and grips are manufactured to satisfy
Temperature monitoring for furnace
Specimen monitoring thermocouples are used to provide the most
accurate indication of the specimen temperature. They are also used
as the control input for a furnace or chamber during the specimen
loaded portion of the test.
Standard thermocouple offerings are Type K.
The K type thermocouple is recommended for most general purpose
applications. It offers a wide temperature range, low standard
error, and has good corrosion resistance. K type is sometimes
called Chromel-Alumel, which is the trade names of the Ni-Cr and
Ni-Al wire alloys.
Ceramic coated rod is to prevent sensor from contacting furnace
directly and guarantee the accuracy.
Temperature controller for furnace
Temperature Control systems are designed for controlling the heat
output of furnaces. The control systems are offered for use with
creep, stress-rupture, or hot tensile systems or they can be added
to an existing frame using an existing furnace.
The control systems are compatible with all furnace systems offered
as new equipment and can be configured to operate nearly any
furnace with any one of several different thermocouple types.
Three zone control systems are designed for heat furnaces with
three separate zones of heating elements, and typically three
different thermocouples to control those zones.
