Looking for sampling valve systems for vacuum melting chamber in order to analyse sample before casting without breaking vacuum.
Can you give me some manufaturers of this kind valves or pertinent key words for searching
All my searches on google gives me results for relatively low temperature applications eg 300°C for pharmaceutical OR petroleum but nothing found till today for 1500-1600 °C molten metal sampling.
Also an idea for materials to deep in the molten bath to take sample are they made of ceramics or refractory metals such Nb or Tantalum etc..?
Thanks
Pierre
