Hi All:
I plan on producing a laboratory tube furnace capable of = to or > 1300 C. Does anyone have any experience working with materials designed for these temps?
I have been pricing Mullite tubes: 500 mm L; ~34 ID; ~40mm OD, 18 G Kanthal A-1 wire (to be wrapped around the tube), Kaowool insulation blanket, and a piece of 'stove pipe' to be the outer tube.
Right now I have two questions:
1) Any suggestions as to the above components? By that I mean suggestions, as to better (in terms of quality and ability to take temperature), grades/types?
2) I need to purchase a thermocouple and thermometer. Recommendations? I also need to design a circuit to adjust power to the wire. What would you guys do and how would you arrange it? I was thinking some sort of dimmer switch (have to handle 2000W power @ 230V) parallel with a bulb as indicator?
Bear with me... When I get it going I'll make a how-to thread with pictures.
Thanks in advance
