Scope of Service

We were awarded contracts to carry-out the entire works to fulfil the client’s technical and health and safety requirements for both new equipment, and its installation.

This work comprised six individual projects.

The first was a turn-key contract to design, manufacture, install and commission a new combination dryer and pre-heating system. This was to be dual fuel, Natural Gas and Gas Oil (diesel oil) using an Allen-Bradley PLC based logic and process control system. The heater uses a 6 MW high velocity cold air burner.

The second contract was to transfer an existing ladle heater to a new position in the melting shop including combustion and control modifications as the turn-key project.

Next was a sequence of contracts to update the remaining three ladle heaters and AOD vessel heater that served the functions of drying, refractory burn-in, preheating and maintaining.
