Abstract Scope |
Hirakud 85kA, end-to-end potline was converted to prebake with GAMI technology during 2006-2009. Later, it was observed that, in the existing pot control system, the application software and control modules are encrypted and hence difficult to modify in line with process requirements. Therefore, control logic and PLC-based system were developed in-house, in correspondence to the Hirakud pot design and process. During the implementation of the new control system, the primary challenges were the acceptability on shop floor and high pot instability due to sludge forming tendency. Also, preventive, and corrective measures are delayed due to high manually intensive operations. To mitigate the above challenges, following actions were taken. (a) technical training was provided to the shop floor personals. (b) Developed control logic was modified based on pot conditions. (c) SCADA features, additional reporting, and auto mailing were developed. This article would provide detailed insight about the development and deployment measures. |
