摘要： PURPOSE:To simplify the preparation process of waste gas desulfurization gypsum, by a method wherein the waste gas of an iron ore sintering furnace is cooled by cooling water and the dust therein is removed by said cooling water while SOx is fixed as sulfite by an alkali washing solution and sulfite in the washing liquid is oxidized by using the metal component collected by cooling water as a catalyst. CONSTITUTION:Soot and SOx-containing waste gas of an iron ore sintering furnace is introduced into an electric dust collector to roughly remove dust therein and treated with a Ca(OH)2.CaCl2-containing aqueous solution used as cooling solution in a gas cooling and dust removing tower. Succeedingly, Ca(OH)2.CaCl2 aqueous solution is used as an absorbing solution in an SOx absorbing tower to fix SOx in gas as sulfite. The SOx and soot-containing treating solution L1 is met with an SOx absorbing solution L2 and sulfite in the absorbing solution L2 is oxidized to sulfate by the catalytic action of iron mixed therein along with the treating solution L1. Both solutions L1, L2 are collectively conc., neutralized and subjected to solid-liquid separation treatment.

摘要： PURPOSE:To obtain sintered ore with a superior reduction powdering index at low temp. in a blast furnace by adding Ni slag crushed finely so as to provide a prescribed specific surface area to starting materials for sintering such as fine ore and coke breeze, mixing them, and sintering the mixture. CONSTITUTION:To said starting materials for sintering is added Ni slag crushed finely so as to adjust the specific surface area, that is, the plane index to 500- 1,000cm /g, and they are mixed and sintered. Thus, sintered ore with a superior reduction powdering index (RDI) at low temp. is obtd. with high productivity. Ni slag contains typically 6.09% T, Fe, 51.81% SiO2, 0.31% CaO, 35.71% MgO and 1.5% Al2O3 on the average.

摘要： PURPOSE:To enhance the dust collecting efficiency when dust is collected from waste gas from a sintering machine with an electrical dust precipitator, by adding sprayed water to the waste gas to control the temp. of the gas at the inlet of the precipitator to a high temp. range. CONSTITUTION:Waste gas from a sintering machine is gathered in a settling chamber 7 through wind boxes 5 and branched boxes 6 and fed to an electrical dust precipitator 9 through piping 8 to collect dust, and after removing gaseous SOx with a desulfurizer 11, the gas is released into the air. At this time, the temp. of the waste gas is measured with a thermometer 21 at the inlet of the precipitator 9, and the gas is cooled with 4 series of cooling units in the chamber 7 so as to control the temp. to the high temp. range of 170-195 deg.C. Since the temp. of waste gas is not excessively high, explosion due to contained fats and oils, etc. is prevented, and a reduction in the dust collecting efficiency of the precipitator due to the excessively low temp. is also prevented. Thus, dust can be safely collected with superior efficiency.

摘要： PURPOSE:To economize fuel such as heavy oil by effectively utilizing waste combustion exhaust gas due to the air-heating furnace of a blast furnace as a portion of heat source, when iron-ore is charged into a drying-classifying machine, and the ore is supplied to the next process such as pulverization, after drying and classification. CONSTITUTION:As to the air-heating furnace 3 of a blast furnace 1, lining material is stretched on the inner surface 19 of a combustion chamber 18, and a burner 20 blows-Out flame in the direction of tangent to the chamber 18 in cyclindrical form, and combustion air and fuel are sufficiently mixed, and perfect combustion is achieved. The combustion air which flows-in through a combustion air inlet 21 generates combustion gas at 1000-1200 deg.C in the chamber 18, and the combustion exhaust gas supplied to an exhaust gas inlet 17 from the furnace 1 through an exhaust gas pipe 14 is mixed with said combustion gas in a mixing chamber 22 so that the temperature is decreased to an arbitrary value, and the mixed gas is charged into the drying-classifying machine 2. The iron ore 4 charged in a hopper 32 is dried and classified by a motor 33.

摘要： PURPOSE:To obtain highly precise data by outputting temp. distribution data of the sectional area only when the distance between the sintered layer sectional area and a camera attains to the prescribed distance. CONSTITUTION:A sintered ore 2 on a pallet 1 of a sintering machine ore exhausting part is broken at the contrarotating part, moves and falls while pushing a plane plate 9. The plate 9 rotates around a horizontal axis 8 with the movement of the ore 2, and the signal of a rotated angle alpha of the plate 9 is inputted to an arithmetic device 11 from an angle detector 10. The device 11 calculates and decides the angle variation, sends the trigger signal to an arithmetic processing part 5 when the angle attains to the prescribed value, and outputs the temp. data obtained from processing the data from an image pickup device 3 to a printer 7. Since the temp. distribution data outputted when the distance between the device 3 and the broken surface 4 attains to the prescribed value, the highly precise data can be obtained.
