Improvement of hearth drainage efficiency and refractory life for high BF productivity and a well adjusted reductant injection rate at varying coke quality

Cel

Blast furnace stability and productivity will be improved under the aspects of high reductant injection rates and varying coke qualities. BF lifetime, security and environmental aspects will be raised additionally. To optimise the tapping strategy and to lower the fuel rate, the hearth drainage efficiency will be investigated with a new dead man porosity parameter, innovative non radioactive tracer tests, new radar and ultrasound measurements, novel analysis techniques and upgraded simulations of fluid flows in the hearth.

Investigations of thermal stresses in refractory and dissection analyses of revamped hearths will improve lining design for campaign prolongation. The estimated annual savings are up to 0.7 M¿/year for each BF in the EU.
