ABSTRACT:
An instrument for measuring the blast air volume within a blast tuyere is connected to a ratio controller which controls the opening and closing of oil and water valves in proportion to one another. A servomotor connects the ratio controller to the oil and water valves attached to a common shaft. The servomotor and the ratio controller are fed back to each other by a set value/actual value comparison. A differential pressure obtained by the blast air measuring instrument can be converted by transducers into a differential voltage and a differential current which controls the ratio controller.
