    Heating furnace

    Hi All, I am trying to model a furnace heating up at a constant rate (10 C/ min) then maintaining a certain maximum temperature, I am doing this using a transient thermal analysis. I wanted to do this using two load steps but I don't know how exactly. Is there a way in ANSYS to use a function to...

    Molybdenum pressure vessel

    @moltenmetal I have been told that ceramics would be even harder to machine than moly. that is why I do not want to use ceramic for the body of the vessel.

    Molybdenum pressure vessel

    @btrueblood Thanks for the sources, they'll come in handy. @EdStainless I need to fit another cylindrical chamber inside this pressure vessel so a sphere would not work.I'll look into ceramic valves, thank you!

    Molybdenum pressure vessel

    @ XL83NL The 1 atm is absolute pressure. I have considered ceramics but they become too brittle and would need some kind of metal lining, which brings me back to moly.

    Molybdenum pressure vessel

    @metengr This is for a research project. I see if I have to follow any regulations, thanks for letting me know. Yes, I understand the theory. @MJCronin It's between TZM and moly. The other materials just aren't as strong at high temperatures and I'm afraid of this thing blowing up like a...

    Molybdenum pressure vessel

    @metengr I am not trying to comply with the ASME code @MJCronin I don't believe anyone has done this before. I need to use moly. because of the high temperatures and nitrogen atmosphere, stainless steel will not work for these temperatures.

    Molybdenum pressure vessel

    Hi, I am designing a pressure vessel out of pure moly. It should hold 1 atm of nitrogen and will be heated to 1500C. The max. diameter is 600mm and it will be about 1m long. I am concerned about sealing the vessel (i.e. what metal to use as a seal) and constructing valves ( since welding moly...
