System for indirect measurement of the heat flows in the annealing process

At technological processes in metallurgy and machine-industries plants is heating of the metals one of the most important operation have influence on production in term of efficiency, quality and costs. In term of quality steel coil annealing is necessary to known temperature inside the object. It is the place with a lowest temperature during annealing process. This paper deals about proposal of the “System for indirect measurement of the heat flows” in the annealing process. This system enable in real time provides information about behaviors of the inner temperatures in the coil during annealing process. Indirect measurement system of the heat flows is based on direct measurement of temperatures on protective cover, atmosphere temperature and coil´s surface temperature in a furnace space of the annealing bell furnace. Proposed system was verified on laboratory measurements.
