Ladle furnaces at Evraz Nizhnii Tagil Iron and Steel Works OJSC produce over 90,000 metric tons of slag per year. As this slag cools, it turns into a fine-grained powder; if the powder cannot be sold, it is temporarily stored until it can be disposed of [1]. We have considered producing easily used flux sinter from the slag generated during …

3.2 Analysis of iron ore sinter Iron ore sinter materials are an important feedstock material for the steel industry. Sintering is a high-temperature agglomeration process. Since fines cannot be used in conventional blast furnaces because they impair the upward gas flow, fines are agglomerated in sinter plants. As a result of increased quality

Use of sized sinter is desirable for the improvement of production rates in the blast furnace. Further, crushing the sinter to 30 mm size at the sinter plant yields a more stable sinter because the smaller size fractions are more resistant to degradation. A supervisory station controls all steps of the sintering process.

The hot sinter crusher reduces the lumps of sinter cake to a size smaller than 150 mm, in preparation for cooling and secondary crushing. Since the sinter cake retains a temperature of around 850 deg C at the time of leaving the strand, the hot sinter crusher operates in a very hostile environment. Hence the design of the hot sinter …
