cryogenic deep freeze boxes
cryogenic deep freeze boxes
(OP)
i am looking for design information on large liquid nitrogen cryogenic deep freeze boxes used in the heat treatment of large steel forgings.
my main concern is the system used to transfer the temperature of the LN2 to the forgings in the container.
it doesn't seem practical to attempt to bathe the product in the liquid as can be done with small items, so i assume there is some type of heat exchanging system.
am i correct in this line of thinking?
my product can exceed 40 tons and 30 ft in length with diameters to 80 in.
any assistance in locating relevant sites is greatly appreciated.
