An Overview of Model Based Control
While glass manufacturers have little control over raw material costs or finished product orders, process control is one area where even minor improvements can trim production costs, improve product quality, and ultimately increase profits. A new model-based controller is outperforming PID controls in glass melter and forehearth applications. The ACSI integrated process controller reduces job change time up to 50% and quickly stabilizes temperature variations in order to provide high quality glass with optimum fuel efficiency. more »

Factors influencing annealing glass breakages
Glass breaks when it is under stresses that it cannot withstand. Each type of glass has different breakage characteristics. In the case of annealing glass, when broken it splinters into sharp fragments, which represent a hazardous situation. Annealing glass may break for many different reasons. We will be focusing on the most common ones. more »
