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： Welded joints of austenitic steels are tested by ultrasonic sound caused to be incident on the joint at an oblique angle thereto. Information regarding the size and nature of reflectors in the joint can be derived from the amplitude of the echoes generated at the reflectors in response to the sound beam. To ensure a definite relationship between the amplitude of the echoes and the nature and size of the reflector, the frequency of the sound use for testing is below and upper frequency limit at which the wavelength of sound in the base material equals the largest peak-to-valley distance of the base metal weld interface in any of the consecutive areas of the interface on which the sound beam is incident at any time.

摘要： In a method of charging metal carriers which contain a portion of fines and are at least partially reduced and carbon carriers to a melter gasifier (10) in which a melt-down gasifying zone (11) is maintained, the metal carriers and the carbon carriers are fed into the melter gasifier (10) above the level of the melt-down gasifying zone (11) and descend to the melt-down gasifying zone (11) and travel through the same forming a metal melt and producing a reducing gas by coal gasification. In order to prevent a partial discharge of the metal carriers from the melter gasifier (10) during the charging of the same and to be able to achieve uniform distribution of the carbon carriers and the metal carriers, both the carbon carriers and the metal carriers are introduced into the melter gasifier centrally above the melt-down gasifying zone (11), preferably gravitationally, with a central strand (32) of metal carriers being formed which is peripherally surrounded by a jacket strand (37) formed by the carbon carriers.

摘要： In a process for the production of molten pig iron or steel pre-products from fine-particulate iron-cintaining material, in a meltdown-gasifying zone of a melter gasifier (1), under the supply of carbon-containing material and oxygen-containing gas at the simultaneous formation of a reducing gas, in a bed formed of sold carbon carriers, the iron-containing material is melted when passing the bed. To be able to employ a charge here up to 100% of which consist of fine ore, while reliably avoiding discharge of the supplied fine ore, a high-temperature combustion and/or gasification xzone is formed by combusting and/or gasifying carbon-containing material under direct supply of oxygen in a killing space (III) formed above the bed, into which high-temperature combustion and/or gasification zone the fine-particulate iron-containing material is directly introduced, wherein at least incipient surface melting of the iron-containing material and agglomeration of the same are carried out by means of the heat released during the reaction of the carbon-containing material.

摘要： The invention relates to a method of deformation-free quenching of work pieces having a free flange, e.g. boiler bottoms, heated up to hardening temperature, and to a device for carrying out the method. Upon removal from the hardening furnace the work-piece, which has been provided with a plane front surface is placed on a plane supporting construction, then the work-piece and the supporting construction are heated up to hardening temperature and subsequently the supporting construction together with the work-piece resting on it is dipped into a basin filled with quenching liquid. The supporting construction is an annular structure made of austenitic, non-scaling material, wherein in the material no microstructure alteration occurs in the range between the temperature of the quenching liquid and the hardening temperature.
