A study of the thermal dynamics of the reheat furnace

Reheat furnaces are for heating slabs to the "best temperature distribution in the shortest time and to do this with the highest thermal efficiency. But these two performance indices are difficult to control and have not been successfully controlled so far. With the advent of on-line digital computer systems this has become possible. A comprehensive study of the thermal dynamics of the reheat furnace is carried out in this thesis with the aim of developing a control system based on computers for these two performance indices.
