Ukrainian steelmaker ArcelorMittal Kryvyi Rih has replaced the caisson of converter No 2 in the converter workshop. ArcelorMittal Kryvyi Rih said “Employees of the converter workshop, taking advantage of incomplete capacity loading and forced downtime of a number of units, perform equipment restoration work. At the beginning of October, the caisson on the second converter was replaced.” The unit is used for removal and primary cooling of converter gases, which are then sent to the gas purifiers through a shielded gas pipe. The weight of the caisson reaches 30 tonnes, the diameter is 4 meters and the length is 11 meter. The replacement of the caisson is the first significant step towards the restoration of converter No 2, which is currently in reserve. The previous unit, which had served its term, was removed with the help of electric bridge cranes, and a working one, repaired by the workers of the steel construction workshop, was installed in its place.
