Abstract
A method and apparatus for determining a non-linear cryogenic cooling profile (16) for the purpose of improving rolled product (5) uniformity based on at least one operating parameter in a cold rolling process; and generating the non-linear cryogenic cooling profile (16) as a function of throttling gas pressure.
Claims22
A method comprising:
- determining a non-uniform cryogenic cooling profile for a discharge of a cryogenic cooling device that is part of an industrial process based on at least one operating parameter of the industrial process;
- and
- generating the non-uniform cryogenic cooling profile.
An apparatus for use in an industrial process, the apparatus comprising:
- a cryogenic cooling device having at least one discharge opening, the cryogenic cooling device being connected to at least one cryogenic fluid supply line and at least one discharge opening, the cryogenic cooling device being configured so that flow of cryogenic fluid through each of the at least one discharge opening is a function of the pressure at which a throttling gas is supplied to each of the at least one throttling gas supply line;
- at least one valve that regulates flow of the throttling gas through each of the at least one throttling gas supply line;
- and
- a controller having at least one sensor adapted to measure at least one operating parameter of the industrial process;
- wherein the controller is programmed to adjust each of the at least one valve to generate a desired cryogenic cooling profile for the cryogenic cooling device based on input from the at least one sensor.
