Abstract
A process for controlling the speed of strand sintering machines through utilization of the temperature of collected waste gas as measured in the collector pipe as the controlled variable provides improved response by utilizing as an additional controlled variable the temperature of the waste gases at the windboxes. Either the average temperature of those waste gases that leave the windboxes at a temperature above approximately 100.degree. C. or the location of the burn-through point as determined from the temperature of the waste gases at the windboxes can be used as the additional variable. In the latter case, the temperature of the collected waste gases can be used to automatically control the desired variable in a secondary cascade-type control loop in which the location of the burn-through point is the actual value and the travel speed is the regulated quantity.
