Title: Method for controlling concentration of si in molten iron in blast furnace
Inventor: YAMAGUCHI KAZUYOSHI
IPC: C21B7/24
Filed: 1985-05-24
Abstract: PURPOSE:To control accurately the concn. of Si in the molten iron to be tapped by measuring continuously the luminance of a raceway part, comparing the measured value with a lower limit value for control, measuring the number of the times when the luminance is below the lower limit and adjusting the charge distribution. CONSTITUTION:Luminance meters 4a-4c are attached to tuyeres 1a-1c at plural tap holes 13a-13c of a blast furnace 12. The signals from the respective meters 4 are inputted to a low-pass filter 8 of a signal processor A from which only the low-frequency components of the signals are outputted (a). The output (a) and the signals (b) from the meters 4 are inputted to a subtractor 9 from which the difference is outputted (c). The difference is formed to the shape of a pulse by a waveform shaper 10 and the number thereof is counted by a pulse counter 11. The pulse count is the number of the times when the luminance drops sharply as shown in the actual waveform (d) of the meters 4. The charge distribution is adjusted in accordance with such number to control the number of green ore falling times in the peripheral direction. The concn. of Si in the molten iron for each of the tap holes is thus controlled.

Filed: 1986-05-15
Abstract: PURPOSE:To protect a device from outside dirt and dust, and to surely operate an optical sensor, by blocking the element of a disk presence/absence detecting sensor on either side by a moving body interlocking with an open wing. CONSTITUTION:An open slider 32 blocks the optical plane of a light receiving element 30. A power source switch is applied, and after a while, the open slider 32 is released from the constraint of an open slider keyer 34, and when a case 11 is inserted, the second claw part 308 of a case hook 33 is kicked at the entrance of the slider, and the stopper function of the case hook 33 to the open slider 32 is eliminated, and the open slider 32 is moved momentarily to the rightside by the force of a coil spring 312. A notch 314 formed on the open slider 32 coincides with the optical plane of the light receiving element 30, and the optical plane of the light receiving element 30 is released from a blocking state. In this case, since a case 11 contains a disk 12, light from a light emitting element 29 is cut off at a lip plate 13, and the light receiving element 30 detects that the disk is contained within the case 11.

Abstract: PURPOSE: To prepare a molding composition of high impact strength and good electrical insulating properties also capable of obtaining molded articles at low cost, by incorporating a metal stearate in a mixture of a phenolic resin molding  material with powdered phenolic resin cured product.  
     CONSTITUTION: 0.05W5pts.wt. of a metal stearate is incorporated in a mixture comprising (1) 95W40pts.wt. of a phenolic resin molding material and (2) 5W60pts.wt. of a powdered phenolic resin cured product. The preferable particle size of said phenolic resin cured product is 0.1W100μ; when exceeding 100μ, the kneading operation during the molding process, may produce a mixture with reduced dispersion homogeneity of the particles, on the other hand, the particle size below 0.1μ cannot be recommended because of effecting the increase in the viscosity of the mixture during the molding process. If the powder content in the mixture exceeds 60wt%, the viscosity increase of the mixture occurs in the similar manner as the above. The preferable metal stearates mentioned above include the salts from Zn, Ca, Sn, etc. More than 5pts.wt. of said metal salts to the incorporated is not preferable because of leading to the degradation of the physical properties of the molded articles to be finally obtained.

This ingot is subjected to working, such as swaging and drawing and is finally made into the electrode of a round rod. The resulted tungsten electrode has the arc ignitability equal to or better than the arc ignitability of the conventional tungsten electrodes and has also the extremely high wear resistance. Since the lanthanum boride is not a radioactive material, the lanthanum boride is safe and facilitates its management.

Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To produce molten iron for steelmaking having a desired carbon concn. from iron scrap even in the case of using coke for blast furnace or briquetted coke as carbonaceous material by adjusting a distance from the center axis of an uppermost tuyere in the blasting tuyeres buried in a carbonaceous material bed to the upper surface of the carbonaceous material bed according to the target melting speed of an iron source. SOLUTION: The distance H (m) from the center axis of the tuyere positioned at the uppermost part in the primary blasting tuyere 3 arranged at the lower part of a vertical type melting furnace 1 to the upper surface of the carbonaceous material bed, is adjusted to the range satisfying the following inequalities according to the target melting speed W (ton/hr) of the iron source. That is, at the time of being W<=4, 0.75+0.01125 W<H<=1.5, and at the time of being W>=4, 1.2<H<=1.5 must be satisfied to adjust the height. Since the melting speed of the iron source is decided with solely the input heat to the iron source caused by the combustion heat of the carbonaceous material and the blasting sensible heat, the adjusting means of the carbonaceous material bed height can be decided with almost only the blasting condition and the carbonaceous material charging quantity.
