Abstract:
     The operation of the temperature control system is accomplished through alternative parallel blasting and single stove blasting. The features of the present invention are as follows. The volume of hot-blast is controlled by regulating the volume of cold-blast entering the hot-blast stove. During the parallel blasting, cold-blast is not blasted into hot-blast, but during single stove blasting, it is blasted into hot-blast through a mixing butterfly valve. In balancing the pressure of the cold-blast during stove switching, the pressure fluctuation in the hot-blast main is monitored automatically so as to requlate the action of a small cold-blast valve. Some precautions have been taken to control the cold-blast valve.
