Radiation heating for barostatically operating presses has heat radiation plate from which heat can be transferred to process material by radiation, direct contact heat transfer and convection

摘要

The radiation heating system has a heating arrangement arranged as a heat radiation plate (1.3) so that a flow of heat can be transferred from it to a process material, e.g. a coated foil, mainly by radiation, direct contact heat transfer and if appropriate by convection. The radiation plate is heated by a heating circuit in which the plate is the load and the heating current can be direct. low frequency a.c. or a higher frequency than the mains.
