North American Stainless commissions new AOD converter torque retainer from SMS group

摘要

For North American Stainless (NAS) in Ghent, Kentucky, SMS group has successfully commissioned a torque retainer for the 160-ton AOD converter no. 1. The customer issued the final acceptance certificate shortly thereafter. The aim of the revamp - which was to reduce the torque that had previously been causing uncontrolled vibrations and damage to the bull gear, bearings, and foundations of the converter drive during AOD converter operation - was fully achieved in every respect. As a result, the uncontrolled vibrations in the gear unit and converter vessel were substantially reduced. The target values were achieved under production conditions shortly after commissioning.
