SYSTEM FOR INDIRECT MEASUREMENT OF THE HEAT FLOWS AT ANNEALING OF THE STEEL COILS

Abstract

The temperature of the thermal processed products is the main variable which designates their quality and energy consumption. In aspect of the steel coils annealing quality is necessary to known temperature inside the object. It is the place with the lowest temperature during annealing process. This paper deals about proposal of the “System of indirect measurement of the heat flows” in the steel coil. This system provides in the real time information about behaviours of the inner temperatures in the coil during annealing process based on indirect measurement of the heat flows. Indirect measurement of the heat flows is based on direct measurement of the temperatures on protective hood, atmosphere temperature and direct or indirect measurement of coil’s surface temperatures. This system was verified in laboratory conditions. Proposed system for indirect measurement of the heat flows is extension of the system for indirect measurement of the inner temperatures based on direct measured atmosphere temperature.
