摘要： PROBLEM TO BE SOLVED: To widen the control range of blowing pulverized fine coal quantity, in the pulverized fine coal blowing into a blast furnace. SOLUTION: This pulverized fine coal blowing method is to arrange two systems of pipings having mutually different diameters of the pipes on the upstream part of a pressurizing tank side in the pulverized fine coal transporting piping from a pulverized fine coal stored pressurizing tank to a tuyere in the blast furnace, and these two systems of pipings are joined at intermediate parts of the pipings. In the case of blowing small quantity, the system of the piping having small diameter is used, and in the case of blowing large quantity, the system of the piping having large diameter is used to widen the control range of the blowing of pulverized fine coal quantity.

摘要： PURPOSE:To control surely the distribution of blast furnace charge with high accuracy by measuring continuously the max. temp. on the surface of the charge at the top of the blast furnace with an IR television camera and controlling the operation by the control values of an influx rate and max. temp. CONSTITUTION:The max. temp. on the surface of the charge at the top of a blast furnace is continuously measured with an IR television camera provided in the mouth of the blast furnace. The case when the measured value in the late period is relatively lower than the measured value with all the measured values of each charge unit is regarded as an influx phenomenon and the influx ratio is defined as (influx ratio) = (the number of influx generated)/(the number of measurement to be changed over). Control values are adequately made respectively with such reflux ratio and max. temp. The operation is controlled in accordance with said control values, by which the distribution of the charge in the blast furnace is surely controlled with high accuracy in correct timing.

摘要： PROBLEM TO BE SOLVED: To provide a facility for injecting powdery material provided with a measuring system for flow-rate of the powdery material with which the flow-rate of the powdery material can accurately be measured, even when changing the type of powdery material and developing the stickiness etc., of the powdery material in an electrostatic capacity type powdery material flow-rate meter.
SOLUTION: This facility for injecting the powdery material, is provided with the measuring system for flow-rate of the powdery material for performing the flowing signal treatment to the measured value in the electrostatic capacity type powdery material flow-rate meter. For correcting the measured value by detecting the stickiness of the powdery material in the flow-rate meter, the output signal in the detector at stopping time of the powdery material injection, is watched and in the case of being not less than the preset value, a prescribed correction is performed to the output signal of the detector. For preventing the measuring error caused by the change of the type of the powdery material, the flow-rate of the powdery material is corrected by comparing the flow-rate value obtained with the electrostatic capacity type powdery material flow-rate meter with the change of weighed value of the powdery material in a feed tank. Further, for avoiding the erroneous output of the flow-rate of the powdery material caused by gas component and change of moisture during purging in a divided pipe with a powdery material flow-rate mask treating part 21, the mask treatment of the powdery material flow-rate for a fixed time during stopping and after starting the injection, is performed.

摘要： PURPOSE:To make it possible to measure the particle size of coke at a place, where a measuring condition is not constant, at a high speed within a short time, by determining a binary level on the basis of the signal distributions, frequencies and standard deviation values of extracted split regions and discriminating the region of a particle being an object to be measured and a background region. CONSTITUTION:The average values of the magnitudes of respective hystogram signals of a particle region (x-mark) and a background region (o-mark) come to V1, V2 and the hystogram (frequency) heights of V1, V2 to H1, H2 and standard deviations to sigma1, sigma2. When these histograms are superposed, a clear bottom appears and the position of this bottom is approximate at the intersecting point H3 of the straight line connecting H1 and V1+3sigma1 and that connecting H2 and V2-3sigma2, and the magnitude of the H3-signal is set to V3. This V3-value is operated by a signal processor 6' and outputted. As mentioned above, the signals of memory 6 being the electric signals of Sij(lm) of all light receiving surfaces are sliced on the basis of V3 dynamically calculated regardless of a measuring state by a signal processor 7 and the distribution of Sij(lm) of V3 or less is determined as a particle.

摘要： PURPOSE:To enable sure discrimination of whether the high luminous particle in the visual field of an observing device is ore or coke in the stage of observing the inside in the shaft part of a blast furnace during the operation of said furnace by measuring the change time of luminance when said particle is cooled by an inert gas. CONSTITUTION:A sonde 5 which has an optical system to permit observation of the inside of a blast furnace 1 and can release gaseous N2 from the tip thereof is inserted into the so-called lump zone 4 from the mid-stage in the shaft part 2 of said furnace down to a level 3 where ore melts. The temp. in this part is high and both coke and ore emit light spontaneously in an incandscent state and are therefore not discriminatable. A cold inert gas such as N2 is ejected from the tip of the sonde 5 in this stage and is applied to the raw material particle which emits spontaneously in the incandescent state, thereby cooling said particle. The degree of a decrease in luminance owing to such cooling is measured with time. The coke has smaller specific heat than the ore and the luminance thereof decreases more quickly than the ore by the cooling with the inert gas and therefore the ore and the coke are exactly discriminated from the difference in said time and the distributing condition of the raw material in the blast furnace is detected.
