摘要： In the process for the production of liquid pig iron 943) or liquid steel pre-products from charging substances comprising iron ore (5) and fluxes and at least partially containing a portion of fines, the iron ore is directly reduced to sponge iron in at least two reduction stages (1, 2) by the fluidized bed method, the sponge iron is melted in a melt-down gasifying zone (39) under the supply of carbon carriers and an oxygen-containing gas, and a CO- and H2-containing reducing gas is produced which is injected into reduction zones of the reduction stages (1, 2), is reacted there, is withdrawn as a top gas and optionally is supplied to a consumer. To achieve uniform reduction of the iron ore at optimum exploitation of the reducing gas, the iron ore (5) in a first reduction stage (1) by aid of the reducing gas is fractionated into at least two fractions having different grain size distributions each, each fraction is reduced by the reducing gas in a separate fluidized bed (6, 15), wherein the reducing gas maintains a first fluidized bed (6) containing the coarse-grain fraction and separates the fine-grain fraction from the same, and wherein, further, reducing gas is additionally introduced into the further fluidized bed (15) directly reduced iron ore (5) is discharged both from the first and from the further fluidized bed (6, 15) and the fine- and the coarse-grain fraction reduced in the first reduction stage (1) are further reduced in at least one further reduction stage (2) operating in the same manner as the first reduction stage (1) and from the last reduction stage (2) the fine-grain fraction is introduced into the melt-down gasifying zone (39) while being agglomerated by provision of oxygen, and the coarse-grain fraction is fed directly into the melt-down gasifying zone (39) gravitationally (FIG. 1).

摘要： In a method for treating particulate material in the fluidized bed method, the particulate material is maintained in a fluidized bed by a treating gas flowing from bottom to top and thereby is treated. To minimize the consumption of treating gas and to reduce entrainment of fine particles by the treating gas, a particulate material having a wide grain distribution and a relatively high portion of fines is used for treatment and the treating gas in the fluidized bed is maintained at a superficial velocity less than the velocity required for fluidizing the largest particles of said particulate material.

摘要： In a method of producing molten pig iron (9) or steel pre-products from lump ore which in at least one reduction zone is reduced to partially and/or completely reduced sponge iron (4) in a shaft furnace, the sponge iron (4) is melted down in a melt-down gasifying zone (8) of a melter gasifier (1) under supply of carbon-containing material (2) and oxygen and while simultaneously forming a reducing gas. To ensure that there will be a specific gap volume in the bed (13) of solid carbon carriers (2) even when charging fine-particle sponge iron (14) and hence that the bed (13) of solid carbon carriers (2) will be thoroughly flown through by gas, at least the sponge iron (4) is charged to the melt-down gasifying zone (8) discontinually, under formation of areas (14) of piled-up sponge iron which are embedded in the bed (13) of carbon carriers (2) and which are superposed and which are separated by solid carbon carriers (2), wherein each of the areas (14) of piled-up sponge iron while sparing a cross section zone (15) of the melt-down gasifying zone (8) extends over the cross section of the same and wherein the reducing gas forming the melt-down gasifying zone (8) flows past the areas (14) of piled-up sponge iron under melting of the same and upwards through the cross section zones (15) that are free from sponge iron and formed from carbon carriers (2), and flows through these zones.

摘要： In a method of flaw classification on and in welds of planar or arcuate plate-shaped workpieces of uniform thickness by means of ultrasonics, the expected flaw areas of the workpiece are pre-examined manually and are then examined systematically using the ultrasound echo image method in separate cross-sectional planes. A B-scan is thus generated, and changing the position of the transducer on the workpiece and/or the transmitting direction enables defects to be located by calculating the delay time of ultrasound waves in the go-and-return directions within the workpiece under consideration of possible reflections at the rear side (8) of the workpiece. For defining the test conditions, part-specific parameters are considered, such as weld type and weld shape (e.g., double-V-weld and bell seam), weld geometry (e.g. seam angle), and part characteristics (e.g. wall thickness), whereupon with the aid of a computer into which the parameters have been inputted, a graphic representation corresponding to a B-scan is generated. In the graphic representation at least one area, in which the density of obtained reflection points per unit of area exceeds a predetermined value, is surrounded by a closed curve of second order, generally an ellipse, and the angular direction of a privileged axis, particularly the major axis of the ellipse, in relation to a reference system, the axis ratio and/or the center location are calculated. Reflection points, located opposite from each other, of a defect are detected, and the ratio between length and thickness of the defect or the orientation tendency, respectively, is calculated, whereupon at least by logically linking orientation tendency and path difference a discrimination between volumetric-type defects, planar defects and a combination of such defects is brought about.

摘要： A method for injecting fine iron ore in a smelting reducing process is disclosed, in which the carrier gas for the iron ore is the discharge gas from a melter gasifier without the need of separate carrier gas. It includes the steps of pre-reducing iron ore in a pre-reduction furnace, melting and reducing it in the melter gasifier, supplying the discharge gas from the melter gasifier through an ascending tube to a cyclone and to said pre-reduction furnace, directing the cooled and cleaned fine iron ore through a recycling system and a melting burner into the melter gasifier. A part of the discharge gas is supplied through a venturi scrubber, a first compressor and a circulating tube into an ascending tube. A part of the compressed gas circulating through the tube is recompressed by means of a second compressor and fine iron ore from a stored source is injected into ascending the tube by the recompressed gas by means of a pneumatic fine iron ore conveying system.

摘要： In a method of casting a metal melt from a metallurgical vessel, in which the metal melt is covered by a slag layer, into another metallurgical vessel, the metal melt is guided through a casting tube, which covers the casting jet between the vessels. In order to reliably ascertain the passage of slag through the casting tube with very little expenditure, magnetic fields are induced in the casting jet by two coils peripherally surrounding the casting tube. The difference of the inductivity variations caused in the two coils by the eddy currents produced by the magnetic fields in the casting jet is continuously measured and compared to a least one limit value and casting is interrupted in case the limit has been exceeded or fallen short of.
