Matt N. Luscombe, project and construction management, Tim Maurice, coke operations stream coach, and Phil A. Roppel, ArcelorMittal Dofasco Inc., Hamilton, Ont., Canada (matt.luscombe@arcelormittal.com)
A new quench tower was constructed at ArcelorMittal Dofasco’s No. 1 Coke Plant, while plant operations continued in the same area. Safe construction of a new tower required a reduction in coking rate to provide a window for construction access, which presented the opportunity for major overhaul of some older equipment
and facilities. |
