The Carbolite Gero high temperature tube furnaces HTRH can be used horizontally up to 1800℃.
The high-grade insulation materials guarantee low energy consumption and high heating rates due to their low thermal conductivity.The insulation and molybdenum disilicide (MoSi2) heating elements are installed in the rectangular housing.The heating elements are vertically hanging and can be replaced easily.At higher temperatures and in the presence of oxygen,MoSi2 develops an oxide (SiO2) layer,which protects the heating elements against further thermal or chemical corrosion.
Three-zone tube furnaces (HTRH-3) can achieve better temperature uniformity than single-zone versions.In these models each zone is equipped with a dedicated thermocouple and controller,which is especially useful to preheat gases required for reactions inside the system.
The HTRH tube furnaces do not include an integral work tube.The work tube must be selected as an additional item.The work tube length is dependent on the application and will vary if used with or without modified atmosphere or vacuum.
The Carbolite Gero STF single zone and TZF 3-zone high temperature tube furnace range is available at 1500℃ and 1600℃ with both models using silicon carbide heating elements.
This range of tube furnaces does not include an integral work tube and one must be selected as an additional item.The work tube length is dependent on the application eg for use with modified atmosphere or vacuum.
The TZF 3-zone high temperature tube furnace has heated lengths of 450 and 610 mm.An extended uniform zone in the mid-section of the work tube is achieved with the use of end zone controllers which track the centre zone temperature and compensate for the loss of heat from the tube ends.
This furnace provides the following advantages: easy loading of samples and uniform heating achieved by locating elements in all six side walls of the chamber.The 1600℃ is ideal for sintering of zirconia dental crowns and frameworks.The silicon carbide heating elements will not cause discolouration of the zirconia.
The HB top hat furnace range has an automatically operated vertically moving hood for heat treatment in air.The moving hood design allows samples to be accessed from three sides.The HB can be equipped with CrFeAl heating wires up 1300℃ or with MoSi2 heating elements for temperatures up to 1800℃.
The HB hood furnaces are available with usable volumes of 80 to 514 litres with the inner space being rectangular in design and the base plate having a convenient height of 750 mm.The hood moves up and down automatically to load and unload the sample.
All debinding applications require the use of an optional afterburner.The afterburner is driven by propane gas and compressed air to burn any evaporating binder.
Carbolite Gero specializes in custom designed furnaces and can also create a customised version of the HB to accommodate specific heat treatment needs.It is possible to equip a gas circulating system to improve temperature uniformity.Several sample thermocouples can be inserted into the furnace chamber to monitor and test the temperature profile.Through the use of a serial interface,the thermocouple data is logged at predefined intervals for evaluation.
The furnace is operated manually with a Eurotherm controller.Other controllers are available upon request.
