ABSTRACT:
A system for evacuating gases from a top blown steel making converter measures any actual value pressure in a chamber between the seal of a closure ring and duct on which this ring is mounted for movement toward and away from the converter mouth, thereby preventing perturbations from affecting the measurements and allowing accurate control of the evacuating blower to balance the rate of evacuation of the gases and the rate evolution therein in the converter at least during a portion of the blow.
