In the end of 2003, a process control system for monitoring a near-furnace slag granulation plant was commissioned on the Severyanka (OJSC Severstal) blast furnace No. 5, the Europe biggest blast furnace, which performs monitoring of the granulation process for a blast furnace product. The control system has been developed on the basis of TRACE MODE SCADA/HMI and ADAM 5000Е controllers (Advantech).
The Severstal process control system consists of two workstations for granulation operators under control of TRACE MODE SCADA/HMI, a workstation for a granulation foreman, network equipment, including a fibre-optic communication line, transceivers, a switch, an RS 485 field industrial network, two cabinets with ADAM 5000Е controllers, peripheral equipment. Besides monitoring the granulation process, the system transmits production process data to a blast-furnace plant MS SQL server and, using an ОРС-exchange, receives data from other SCADA-systems of the blast furnace No. 5 process control system, which were not accessible earlier. Now, being on any granulation plant, a process engineer has the whole volume of production process information about the operation of all units.
With implementing of the new process control system based on TRACE MODE SCADA, it has become possible to refuse instrumentation and control disk recording devices and an opportunity has appeared to monitor the operation of both granulation plants from any operator's control desk as well as from a granulation foreman's office.
The control system has allowed to detect bottlenecks in the operation of the Severstal equipment, reduce the equipment operation in idle conditions to a minimum. |
