The LD-HC and K-OBM converters of the Cockerill Sambré Chertal and Marcinelle steelworks have been equipped with various sensors in order to achieve more efficient control of the refining. At the Chertal steelworks, a sonicmeter and a fume temperature sensor were used. At the Marcinelle steelworks, the study was based on the fume temperature, the boiler pressure and the waste gas concentration measurement. The objectives were the control of the dephosphorisation with the decrease of the reblow rate, and the development of a quick tapping procedure through a better prediction of the oxidation state of the melts.
