Tata Steel, the flagship company of the Tata group, entrusted Fives to upgrade the level 1 control system at the existing gas fired pusher type reheating furnace installed at the merchant mill of their Jamshedpur Works, India.
The furnace, with 72 tons per hour capacity, was originally commissioned in 1958. It had a single loop controller and instruments for furnace heating control. The complete changeover of the heating control system will include Fives’ advanced proprietary technologies.
Fives is to design and supervise the erection and commissioning of a PLC based furnace control system, including logic and HMI development for the heating system. The new system will include associated process loops such as: double-cross control for the zone combustion, automatic adjustment and control of the furnace and combustion air pressure, complete safety system such as auto isolation, auto purging alarm & annunciations, safety control, and electrically actuated control valves.
