Objective

The injection of slag correction components into the blast furnace is expected to influence the metallurgical reactions in the lower part of the blast furnace positively due to an aimed change in the slag composition in the hearth and a better raw material utilisation. The different injection techniques (reductant mixed with flux, reductant and flux separate) shall be evaluated comparatively. The experimental investigations shall be carried out at two different blast furnace plants. The results shall be compared with thermodynamic calculations to obtain generally acceptable knowledge applicable for an optimised slag metallurgy in the blast furnace operation. Based on that the development of an operational concept for an optimum slag correction in the blast furnace by tuyere injection shall be worked out.
