Improvements in sintering

Sintering machine 1 at OAO Zaporozhstal’ has been reconstructed with increase in the sintering area from 62.5 to 75 m 2 . A vibrational screening system ensures that the content of the −5 mm fraction in skip sinter is 10.1–11.5%. The gas-purification equipment is reconstructed, with the introduction of two electro-filters and absorbers. That ensures compliance with the maximum permissible dust concentration of 50 mg/nm 3 and reduces the SO 2 concentration to ∼400 mg/nm 3 . Eirich R19 Konti heavy-duty mixers and granulators are used to prepare the dust for utilization.
