Blast Furnace Shutdowns, Overhauls & Maintenance
Blast furnace and steel manufacturing shutdowns require rapid, highly coordinated maintenance, mechanical overhauling, and software commissioning cycles. With down-time costs running extremely high, Excellors delivers expert site engineering squads, specialized tooling, and NDT inspection crews to execute critical maintenance cycles on-schedule.
We provide end-to-end technical support for shutdowns, including structural overhauling, replacement of worn refractory linings, mechanical re-alignment of drive units, and logic integration of process control interlocks.
