Roll Performance in the Hot Strip Mill using Proven Welding Technology and Specially Developed Welding Materials to Reduce Operational Costs and Maximize Productivity

摘要

Weld surfacing of selected steel mill rolls should be considered as a surface engineering design tool that can be used to apply a surface with, enhanced corrosion, wear, and mechanical properties on an existing used roll or a more cost effective substrate. The full benefits of the technology of roll welding can only be realised if the wire manufacturing and the welding process are fully understood and carefully controlled. The successful application of this technology improves roll service performance, minimises un-planned plant down time and hence drives down maintenance costs while maximising plant utilisation and profitability.
