Heat treatment machine using resistance heating
Heat treatment machine using resistance heating
(OP)
I am offered to buy a heat treatment (stress relive, quenching and tempering) machine which utilized resistance heating for a long tubes of non-regular cross-section. (4130). I have no experience in such a process and have a number of reasonable doubts about this process. Can anybody share with me his/her experience in using this process?
Thank you.
Thank you.

My concerns are: how uniform is heating; how to grip a tube of non-regular cross section; when would happen when the tube is realized – I mean, if the residual stresses will distort the tube; how accurate the thermo sensor should be placed to control temperature for tubes of different diameters and lengths, etc.
