Blast Furnace “C” Rebuild

Graycor Industrial recently completed a fast–track rebuild of Blast Furnace "C" at Severstal′s Dearborn, MI, plant. This complex design–build challenge required six months of preplanning to develop a unique and innovative approach to complete the construction phase within the scheduled 100–day outage.

The project also included construction and installation of a casthouse weighing approximately 1,500 tons and measuring 100 feet long by 80 feet wide by 100 feet tall. This massive casthouse was preassembled simultaneous to the furnace being constructed. After the preassembled furnace was erected in five major lifts, the casthouse was rolled into place utilizing four heavy haulers.

Working non–stop, our team – consisting of 1,300 employees at its peak – successfully completed the rebuild without incident in under 98 days. This was not just a tremendous success for Severstal and Graycor Industrial; it was also a benchmark feat for the steel construction industry as a whole.
