SSS has developed a PC based automatic control system(installed at various sites) for electrode movement of Ladle Refining Furnace.
The movement of three electrodes will be controlled independently based on the collective requirement of current, defined in the programme. Based on the field requirement, the computer will select the right amount of current and voltage selection.
Based on the above parameter and in consultation with your experts/consultants, SSS will develop a process control Software for controlling the electrode current and its movements. When given Start command from the computer, the PC will then automatically set the required Current parameters without any operator intervention.
Reason for going to a PC based automation.
| STANDARD L.R.F.CONTROL | SSS. L.R.F.CONTROL | ADVANTAGE |
| Single Control panel with Multiple instrumentation | Single monitor with multiple screens | More information, Less Capital cost |
| Experience based Chemistry/Temperature Estimates. | Computer modeled | Time, Energy and refractory saving |
| Manual Collection of Data | Automatic acquisition (e.g. Weight, Chemistry, Temperature, Aims etc.) | Convenience and accuracy |
| Note: To effect this, the system should have Automatic weighing, Communication with Spectrometer, Communication with Temperature measuring instruments etc. | ||
| Manual adds calculation | Adds wizard | Least cost material, accurate chemistry control |
| Operator dependent practice and processing | Automated processing | More consistent product |
| Manual record keeping | Automated heat summary. | Convenience, Quality control |
| Remote viewing of live data not possible | Remote viewing and if required, controlling is possible through internet. | More convenient and systematic control |
| * Condition apply | ||
| Networking with Lab, Pyrometer, Weighing scales MIS etc. not possible | Networking with Lab, Pyrometer, Weighing scales MIS etc. is easily attained after interfacing with such instrumentation. | Accurate and perfect control |
