In many sinter plants the sinter cooler over decades of operation is the cause of the bottleneck in terms of plant productivity as well as noise and dust emissions. The solution for a retrofit of the sinter cooler may be a combination of different elements: • Increasing the effective volume:
Steelmaking is a waste-intensive process. A modern integrated steel plant may lose up to 10% of the iron units in its feed to various waste streams, in addition to the significant volumes of slag and other non-ferrous waste generated in the process (Table 1).Recovering these iron units in the process is one of the primary functions of a sinter …

Meantime FACOR had been closely watching the technical development of use of sintered pellets in Outokumpu and SRC Processes which need still lower specific power. But the high capital requirement for a pelletisation plant kept FACOR from introducing pellets feed to their Ferro chrome furnaces. So this was postponed to be adopted in future.
