Abstract
Casting powder is to be fluidized for feeding to a mold for continuous casting. The gas flow providing the fluidization is controlled in response to bath surface temperature, monitored by means of a curved copper sheet, serving as radiation detector. A thermofeeler is attached to the sheet and controls a pneumatic control circuit for the fluidization gas.
