Abstract

A novel automatic control system for a billet reheating rotary hearth furnace has been developed. The control system consists of a component that calculates the billet temperature and a component that calculates the optimal furnace temperature set-point. This system has been applied to the rotary hearth furnace of the medium-size seamless tube mill at Sumitomo Metals´ Wakayama Steel Works, has achieved energy savings of 5000 Kcal/ton in billet heating, and has also satisfactorily maintained the extracted billet temperature within the required temperature tolerance
