摘要： PURPOSE:To prevent rephosphorization during dephosphorization utilizing dephosphorization slag produced as a by-product by adding a lime-base flux to molten iron, by adding molten converter slag. CONSTITUTION:Molten iron is transferred from a blast furnace 1 to a desiliconizing stage 2, where it is desiliconized. To the desiliconized molten iron are successively added molten converter slag from a converter 4 and dephosphorization slag produced as a by-product in the following dephosphorizing stage 3. The dephosphorization slag may be blended with the molten converter slag and added to the desiliconized molten iron. They are transferred to the dephosphorizing stage 3, where a lime-base flux is added to dephosphorize the molten iron. The dephosphorized molten iron is transferred to the converter 4, where steel is manufactured.

摘要： PURPOSE:To enable the accurate measurement of low-frequency vibrations of the outside air even when there is a slight wind by a method wherein a microphone covered with a wind-breaking screen is set in a box having a gap through which a change in a static pressure of the outside air can be propagated into a space inside the box, and said low-frequency vibrations are measured by the microphone. CONSTITUTION:The junctions of a top face 15 and side faces 12, 13 and 14 of a wind-breaking box 11 are closely sealed by a gummed tape or the like, and a bottom face thereof is opened. The box 11 thus formed is set upward in a flat place when it is employed. This box is designed so that only the vibrations of the atmosphere and the outside air are propagated to the inside thereof through a gap between a setting plane and the lower-edge portion of each of the side faces 12, 13 and 14. A microphone 2, which is mounted on a tripod 17, covered with a wind-breaking screen 18 and housed in the wind-breaking box 11, is used as a sensor for measuring the low-frequency air vibrations of the outside air. By this constitution, the low-frequency air vibrations can be measured accurately even in the condition that there is a slight wind.

摘要： PURPOSE:To improve dust precipitating efficiency by hammering discharge electrode parts which charge the dust of which the apparent electric resistivity has specific values and dust precipitating electrodes which capture the charged dust respectively at specific frequencies. CONSTITUTION:Discharge electrode parts which charge the dust having 10 - 10 OMEGA.cm apparent electric resistivity and dust precipitating electrodes which capture the charged dust are hammered respectively at 1-10 times frequencies in 10min. In other words, both electrode parts exhibit their ability always in the finest condition on account of large hammering frequencies. Since the apparent electric resistivity is set at 10 -10 OMEGA.cm, rescattering phenomena of the charged dust are obviated. As a result, the concn. of the dust in the outlet is decreased always in a stable state and since the electrode parts are stuck always with small dust, the decrease in the rate of neutralization is obviated and the quantity of electric charge is reduced as compared to that in the prior art.

摘要： PURPOSE:To enable energy-saving drying of laver sheet in high quality and production efficiency by radiating far infrared ray from an external source to a far infrared-radiating ceramic applied to a laver screen and utilizing the absorbed far infrared ray for the drying of a laver sheet. CONSTITUTION:A laver sheet pasted on a laver screen is transferred into a drying apparatus and dried with far infrared ray radiated from a far infrared ray radiating ceramic such as alumina. In the above process, far infrared ray transmitted from external source is absorbed to the far infrared ray radiating ceramic attached to the laver screen and the absorbed far infrared ray is utilized for the drying of the laver sheet. Preferably, the far infrared ray radiating ceramic at the laver-screen side is calcined at a low temperature and the far infrared ray radiating ceramic at the drier side is calcined at a high temperature.

摘要： PURPOSE:To prevent stay of slag flowing and to sufficiently utilize treating effect under continuous flowing by blowing a molten iron treating agent from upper part at a specific angle to the molten iron flow toward the molten iron flowing direction. CONSTITUTION:The molten iron treating agent 4 from a lance 3 is blown from the upper part at 85-60 deg. angle toward molten iron flowing direction into the molten iron flow 2, flowing in the molten iron trough 1 in a blast furnace. In this way, the slag 5 formed by reaction is flowed toward downstream. Therefore, reaction between the slag and metal, becomes insufficient, and unfavorable reaction of rephosphorizing, resulfurizing, decarbonizing, etc., can be restrained.

摘要： PURPOSE:To prevent solidification as lumpy slag and to easily treat it, by refining continuously molten iron in a molten iron trough and slurrying the generated slag as cooling rapidly and crushing by the specified rate of an injecting flow water at the time of removing the slag from the trough. CONSTITUTION:The molten iron 4 from a blast furnace is introduced to the molten iron trough 2, and suitable quantity of refining material is injected, and then the generated slag 6 is over-flowed from a dam 10 of the molten iron trough 2 and flowed out to a branched slag trough 8. Then, this slag trough 8 is inclined by about >=1/10 toward one side direction and in case of the generated slag 6 with bad fluidity, it is mixed partially with the blast furnace flag 12. At just flowing out the slag 6 from the slag trough 8, the slag is injected under high pressure from the nozzle 14, 16 by not less than two times of the injecting flow water 18, 20 rate to the generated slag 6, to make it into slurry by cooling rapidly and crushing. The generated slurry 22 is sent to solid-liquid separator 26 through a slurry trough 24, to separate water granulated slag from water. In this way, the length of the slag trough 8 is made as short as possible and the trouble caused by clogging of the slag trough 8 is prevented.
