摘要： Method for determining the image clarity of a surface of a sheet strip or similar, including projection of an image on the surface, detection of a virtual image of the image projected onto the surface and the processing of the detected virtual image into a signal which is presented as a measure for the image clarity of the surface, wherein the image reflected onto the surface is composed of a two-dimensional array of distinct light spots, whereby the processing of the detected virtual image includes the steps of (i) digitizing the detected virtual image with reference to at least one greyness discriminator value, and (ii) determining, for the greyness discriminator value, the number of distinct light spots in the digitized detected virtual image, and from steps (i) and (ii) obtaining a signal measuring image clarity of the whole area of the surface illuminated by the image projected onto the surface.

摘要： A hot-blast main for a hot-blast stove system of a blast furnace has a refractory structure comprising a plurality of courses of refractory bricks. At least a first one of the courses has at least one part thereof comprised of a plurality of expansion-joint forming bricks whose dimensions and arrangement are such that, in the cold condition of the hot blast main, there are provided radial expansion joints between the expansion-joint forming bricks and at least one adjacent part of the hot-blast main. At least some of the expansion-joint forming bricks of the first course are placed radially staggered relative to at least one adjacent such brick in each case, so that the expansion joints are provided at both the radially inner side and the radially outer side of said first course. This construction accommodates differential thermal expansions and provides good stability of the structure.

摘要： In a batch production of steel, a charge including solid scrap is loaded into an oxygen steel converter, the scrap is melted and the charge is refined in the converter by means of an oxygen blowing lance inserted into the converter through the converter mouth. To enable larger quantities, i.e. over 30% of scrap to be used, the solid scrap is heated by combustion of fuel in the converter using the oxygen blowing lance whose outlet is, at least initially, below the top level of the scrap in the converter, so that the combustion gases formed by the combustion of the fuel pass upwardly through the scrap.

摘要： Metal packaging can body, for use in forming a can by attachment of at least one lid, has a generally cylindrical body portion and a flanging rim which is intended for the subsequent attachment of the body portion to the lid. The flanging rim is at least partly of wall thickness greater than that of the body portion. To save material and costs, the flanging rim has at least one portion which decreases in wall thickness in the axial direction away from said body portion. The invention is especially applicable to deep-drawn and ironed products.

摘要： In the electrolytic metal coating of a strip-shape metal substrate, the substrate is passed in a continuous process as cathode through an electrolytic coating apparatus having an insoluble anode, the cathode and anode being connected to an external voltage source so that metal ions are deposited onto the substrate from an acidic electrolyte between the cathode and anode. To increase the anode service life and reduce power consumption, a hydrogen-providing gas, e.g. molecular hydrogen, is fed to the anode and a catalyst is available at the anode, so that under the influence of the catalyst electrons and hydrogen ions are formed from said hydrogen-providing gas, the hydrogen ions passing into the electrolyte.

摘要： In a method of mixing two or more gas flows, the gas flows are passed through an array of at least three parallel adjacent guide conduits so as to emerge from said conduits into a mixing zone as a corresponding array of parallel adjacent streams flowing in the same direction. The gas flows are distributed alternatingly in said conduits so that each said stream has, as each of its neighbors, a gas stream from a different said gas flow. To improve mixing and shorten the required length of the mixing zone, the streams derived from the respective gas flows have different velocities at their emergence from the guide conduits into the mixing zone.

摘要： In a method of making coke in coke-ovens of a coke oven battery, the coke temperature is measured using at least one infra-red sensor after pushing of the coke from a coke-oven and before quenching of the coke. A value corresponding to the difference between measured value of the coke temperature and a predetermined reference value is determined for each of a plurality of coke loads pushed from a series of coke-ovens. The mean of said difference values is determined and the combustion gas supply to at least a plurality of coke-ovens of the battery is adjusted in dependence on said mean of the difference values. In this way, better control of the temperature of the coke at the end of the coking time can be achieved, with less deviation of the coke temperature from the reference value.

摘要： A gas-transmitting wall element for a metallurgical vessel having a refractory lining is described which is subject to low wear, is reproducible and makes unnecessary continuous blowing of gas through it. The element has an outer sheet metal box, open at one end, and a refractory filling in the box comprising at least one brick spaced from the closed end of the box, into which a gas inlet opens. The brick contacts the metal sidewalls of the box and has grooves to allow the gas to pass to the open end of the box.

摘要： A channel structure, i.e. iron trough or iron runner, for flow of molten pig iron during tapping of a blast furnace, comprises a wear lining which provides the surface along which the iron flows, a permanent lining outside the wear lining and an outer lining of high thermal conductivity outside the permanent lining. The outer lining has a bottom wall and two opposed side walls thermally connected at their lower ends to the bottom wall. To improve resistance to thermal stress, outside and adjoining at least one, but not all, of the walls of the outer lining, there is at least one refractory insulating lining layer, and the other or others of the walls of the outer lining are thermally coupled to heat dissipating means.

摘要： The level of the surface of a bath of molten metal beneath a fluid layer of slag in a metallurgical vessel is measured by a detector which is moved through the slag layer into the metal bath and then withdrawn. To improve accuracy and to avoid the need for a separate measurement the detector used comprises an oxygen concentration sensor which emits signals indicating the boundary between the molten metal and the slag, whereby the height of said boundary is determined.
