Abstract

Especially during transitions between two different tin plate products, large differences in required heating power can arise. For these transitions a sophisticated control system is required which minimizes transition times and limits temperature deviations from the target temperatures. Conventional control systems in Radiant Tube Furnaces (RTFs) vary the fuel gas flow when a higher or lower furnace temperature is required. This is a relatively slow process. Controlling the line speed is a much more powerful means of control. Two physical-mathematical models have been developed to calculate the heat transfer in the RTF for steady and transient state situations. Process measurements in the RTF and in a one-tube test furnace have been used to determine the heat transfer characteristics of the radiant tubes. Empirical relations have been derived from these process measurements which have been programmed into the physical-mathematical models.
