Abstract: Now-a-day Information Technology (IT) has helped the process industry, particularly steel industry, to become more efficient, highly productive and highly cost effective. Expert system and mathematical model based control systems are now become the integral part of various processes. Sintering is a major process in making steel. In view to this, more and more sinter plants now-a-day are coming equipped with latest and state-of-art automation & IT systems. Steel Authority of India Ltd. (SAIL), under its current modernization program, has installed number of modern, state-of-art sinter plant in Rourkela Steel Plant, Bhilai Steel Plant & IISCO Steel Plant. The objective of this paper is to discuss various model based level-2 systems in recently commissioned Sinter plants of SAIL.

Keywords: Sinter, permeability, mathematical model, moisture control, control system, process optimization.
