SUMMARY:Andritz advanced furnace control improved quality and productivity for SSAB’s continuous annealing line
DESCRIPTION:SSAB intended to improve the quality and productivity for their existing Continuous Annealing Line (CAL) in Borlänge, Sweden, so they chose ANDRITZ Advanced Furnace Control (AFC). A new generation of AFC was first time applied on SSAB’s CAL. It consists of a modular design with a newly developed cooling model and a brand new multi model predictive control. 
The precise physical model for all heating and cooling sections acts as virtual sensors, which provides real time trends of the temperature distribution within the furnace and acts as a huge source for Big Data. 
The multi model predictive control ensures collaboration between all models to enable constant high quality heat treatment by assuring maximum productivity. It runs in fully automatic furnace operation and optimizes line speed, heating power and blower speed for all furnace sections. The predictive capability of the model opens a lot of new opportunities for online and offline improvements of the production. 
Some examples, that have been developed together with SSAB, are the online compensation of the varying strip emissivity over the coil length and the optimization of the heat cycle recipes. Furthermore, the visualization of the prediction also facilitates operators to have a better situational awareness of the furnace operation. 

This paper reports on details of the installation of AFC at a CAL of SSAB and the resulting increase in quality and productivity.
