摘要： A method of manufacturing sintered ore by charging a blended raw material, which contains a raw powder ore, solvent and fuel, onto a pallet of a sintering machine to form a raw material packed bed and then igniting a surface of the raw material packed bed to effect sintering reaction downward from above. In the method of manufacturing sintered ore and the sintering machine, when an upper layer of the raw material packed bed is adequately fired, a mass flow rate of oxygen containing gas supplied to the raw material packed bed is changed to be 1.01 to 2.6 times the mass flow rate of oxygen containing gas supplied in the range, in which the upper layer of the raw material packed bed is fired, to effect sintering, thereby obtaining a high yield and a product having an excellent quality. More preferably, when a tip end of a region, in which a combustion fusing band is formed, reaches a position below 20 % of a height of the raw material packed bed from the upper layer of the raw material packed bed, a mass flow rate of oxygen containing gas supplied to the raw material packed bed is changed in the above manner to effect sintering.

摘要： A rapidly solidified foil for a ring-like welding material is formed by spraying a molten metal on the side of a roll rotating at a high speed and rapidly solidifying the same, and the ring-like foil is formed into a coil. It has also a fold portion concentric with the rings. A nozzle opening surface is opposed to the roll side vertical or inclined to the axis of rotation, the opening is slit-like, the longitudinal direction of the opening is parallel to a radial direction of the roll side, the molten metal is sprayed, and the rapidly solidified foil is peeled. When pipes such as steel pipes are butt-welded with the pipe end surfaces vertical to the axis of the pipe, the rapidly solidified foil is placed between the pipe end surfaces. The rapidly solidified foil is produced with high yield and high working factor. Because the thickness in the width direction of the ring foil is made uniform or the surface area of the welding material is increased, the welding accuracy and welding strength are improved.

摘要： In order to separate and recover iron from nonferrous metals such as zinc contained in ironmaking dust in a short time, a mixture of ironmaking dust with a carbonaceous material in a ratio of 1:0.05 to 0.3 and a reducing gas containing hydrogen or carbon monoxide are fed into an external heating type rotary furnace, where the iron and the nonferrous metals are reduced with the reducing gas and zinc is vaporized and separated from the solid. The steam and carbon dioxide simultaneously produced at that time are reacted with the carbonaceous material to yield hydrogen and carbon monoxide, thus permitting a highly reducing atmosphere to be maintained in the furnace.

摘要： A method for operating a shaft furnace which comprises charging the furnace with an iron source having a low degree of metallization and thus requiring reduction, an iron source having a high degree of metallization and thus requiring nothing but melting, and a solid fuel, and blowing an oxygen-containing gas at ordinary or higher temperature up to 600 DEG C into the furnace through tuyeres to reduce and melt the iron sources. The optimal values of eta co (gas utilization factor) are determined from the average degree of metallization of the iron sources, and the shaft furnace is controlled so that the effluent gas from the furnace has the optimal eta co values. The control is accomplished by regulating the height of the charge, regulating the height of the coke bed, etc., using multistage tuyeres, and radially partitioning the charge. Thus, the iron sources can be efficiently reduced and melted at a low fuel ratio.
