Rail Mill Head Hardening Facility

Location: Pueblo, Colo.

Client: CF&I Steel LP

Burns & McDonnell provided the construction and installation engineering for rail head hardening equipment. The project involved extensive structural modifications to the existing buildings, including removal of several columns. A new building was designed to interface with four existing structures constructed at different times. The oldest structure was more than 100 years old.

Electrical systems included medium voltage (6,900 volts) power distribution and motors, AC and DC drives, AC motor control center, and control system instrumentation. A majority of the systems were designed to be installed in high temperature areas.

Mechanical systems included cooling water, hydraulics, central grease, compressed air and high ambient HVAC systems. A control pulpit was designed to house control systems, communications systems and video monitoring of the process.

The design team partnered with the owner and contractor and had extensive involvement during the construction phase. All construction was accomplished while keeping the rail mill in production.
