Cryogenic system of a dusting of rolls of the rolling mill

Cryogenic system of a dusting of rolls of the rolling mill

Composition of a system:

  • Transport storage vessel of liquid nitrogen;
  • Flexible transfer line of delivery of cryocoolant to rolls;
  • Disrtibutive collector with injectors of a pulverization of nitrogen;
  • Contact node of measuring of temperature of rolls;
  • Regulated valve of cryocoolant delivery;
  • The microprocessor type controller of temperature.
