Furnace Optional Accessories

Furnace Optional Accessories

A wide range of optional accessories for the furnace include:

wall mounting brackets
'L' stand allowing vertical and horizontal operation
selection of worktubes including: impervious aluminous porcelain (IAP), mullite,
recrystallised alumina (RCA), metallic (APM), sillimanite and silica.
spares kit
chart recorders
ceramic insulation plugs
radiation shields
calibration certificates
work tube seals for vacuum/controlled atmosphere applications
over temperature protection
probe thermocouple for calibration and accurate measurement of work piece temperature
separate control boxes
time switch
process timers
gas safety systems
gas flow meters
gas safety systems
furnace tables with heat resistance surfaces

Worktubes for the furnace

Some tube furnaces have an integral ceramic worktube, others require one to be added to operate
All require an additional ceramic or inconel worktube to allow the use of a gas atmosphere
Various worktubes are available to suit different applications
Silimanite - porous, good thermal shock resistance, maximum temperature 1500C
Impervious aluminous porcelain (IAP) - impervious, maximum temperature 1400C
Mullite - impervious and resistant to flux, sulphurous & carbonaceous atmospheres, maximum temperature 1500C
Recrystallised alumina (RCA) - impervious and highly resistant to chemical attack (99.7% Al2o3), maximum temperature 1800C
Advanced powder metallurgy (APM) - impervious FeCrAl alloy tube, not susceptible to thermal shock, but unsuitable for use inside (MTF & CTF) wire wound tube furnaces, maximum temperature 1300C

Insulation plugs & radiation shields for the furnace

These vital components must be fitted to all tube furnaces to prevent heat loss and ensure good uniformity
Various types are available for different applications
Ceramic insulating plugs
Type C for a non atmosphere application
Type D for an inert gas atmosphere application
Radiation shields
Type D metal discs for up to 1200C high purity atmosphere or vacuum
Type D alumina discs for up to 1800C high purity atmosphere or vacuum
Probe thermocouple
Temperature indicator
Type C insulation plugs
Type D insulation plugs
Radiation shields
Work tube end flanges
