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.

Controlling the feeding of casting powder

A parallelogram-like collapsible frame has centering rolls in opposite corners for engaging one roll each per track and across the track path; these centering rolls establish a center line of reference on which one or two, straight or curved rulers are pivoted to engage other track rollers, and the angle of pivoting represents the radius of curvature or a deviation from a desired radius.

The apparatus includes a parallelogram-like foldable frame, opposite corners of which carry centering rollers to position the frame between two opposite track rollers; feelers measure the distance to the latter. The frame can be hung between the tracks or can be self-propelled by a belt drive. Some of the centering rollers can be used for reeling tests of the track rollers.
