The physical, or more accurately mechanical, properties of cultural materials have been largely responsible for the current “standard museum environment” of around 22˚C ±0.5˚C and 50% ± 5% relative humidity (RH).
The real problem is that low temperature severely embrittles materials such as paints.

According to treating the materials of pressure vessel and product technological requirements, the rising time and velocity of the temperature should be controlled, as well as the time of keeping this temperature.
(1) The general PID parameters were summed up according to the past experience, a group of PID parameters maybe make some annealing process temperature control good, but when the steel material has changed or other reasons what make the object changed, the reasonable PID parameters couldn’t established only by experience.
