摘要： PURPOSE:To obtain a pattern classification device with high classification ability by providing a rotary processing means which rotates the arranging order of plural input signals and impresses a signal compensating positioning on the plural input terminals of a network. CONSTITUTION:The rotary processing part 1, a statistics calculation processing part 2, neural networks 3 and 4 and a data selector part 5 are provided. The signal compensating positioning by rotating the arranging order of the plural input signals is impressed on the input terminals of the network. Even if the pattern of the input signal is rotated such as the temperature distribution signal of a blust furnace, for example, in the rotary processing part 1, the position of the rotary direction is arranged so that it coincides with the rotary direction position of a reference pattern (pattern for learning), and the signal is impressed on the network. Thus, the rotary position of the input signal pattern does not affect the network. Consequently, the pattern classification ability of the network considerably improves.

摘要： PURPOSE:To measure the temperature distribution and the porosity of coke at the surface part of furnace core and the raceway part individually with high spatial resolution in the form of two--dimensional image data by a structure wherein the sound wave propagates through the peripheral tuyere part while avoiding the central region in the furnace requiring high sound pressure. CONSTITUTION:When the physical characteristics at the surface layer region 60 of furnace core and the raceway part 70 are measured, scan signals 31, 32 are delivered from a CPU 21 to a transmission side scanner 22 and a receiving side scanner 23 in order to select a sound wave generator and a sound wave receiving sensor being used for measurement. When a sound wave generator (a1) is designated, for example, ten (N) units of receiving sensors b2-b6, bM4-bM are selected. Upon receiving a transmission signal 41 from the scanner 22, the generator (a1) transmits a sound wave in the furnace and N receiving signals 42 are stored in the CPU 21 through the scanner 23 and a waveform measuring apparatus 24. Upon finishing the scanning for M tuyere, the CPU 21 configures the stored data again and displays 25 the two-dimensional distributed image of physical characteristic values.

摘要： PURPOSE:To automate the decision of furnace top pressure at the time of decreasing the pressure for blowing-down or at the time of increasing the pressure for reopening the operation and to prevent the development of blow-through or hanging accompanied with the pressure decrease/ increase. CONSTITUTION:A memory 20, in which correlation (Di, Dd) between the blasting pressure and the furnace top pressure is resistered, is installed and the blasting flow rate PV1 and the blasting pressure PV2 are inputted. The ideal blasting pressure (Pv1Xa: PV1Xb) and the blasting pressure PV2 are compared, and at the time of increasing the pressure, in the case of being PV1Xa >=PV2, the PV2 is selected, and in the case of being not so, the PV1Xa is selected. At the time of decreasing the pressure, in the case of being PV1Xb>=PV2, the PV1Xb is selected and in the case of being not so, the PV2 is selected, and the selected value is converted to the furnace top pressure aimed value SPt according to the correlation (Di, Dd). By this method, the blast furnace operation is stabilized.
