摘要： A method of making a high strength head-hardened crane rail and the crane rail produced by the method. The method comprises the steps of providing a steel rail having a composition comprising, in weight percent: C 0.79 - 1.00%; Mn 0.40 - 1.00; Si 0.30 - 1.00; Cr 0.20 - 1.00; V 0.05 - 0.35; Ti 0.01 - 0.035; N 0.002 to 0.0150; and the remainder being predominantly iron. The steel rail is cooled from a temperature between about 700 and 800 °C at a cooling rate having an upper cooling rate boundary plot defined by an upper line connecting xy-coordinates (0 s, 800 °C), (40 s, 700 °C), and (140 s, 600 °C) and a lower cooling rate boundary plot defined by a lower line connecting xy-coordinates (0 s, 700 °C), (40 s, 600 °C), and (140 s, 500 °C).

摘要： A method and a tool (10) for forming a seal in a lock chamber (3) of a sheet pile are proposed. The method comprises the steps of: introducing a seal forming tool (10) into the lock chamber (3); injecting a sealing material into a distribution chamber (50) of the tool (10) from where it axially fills longitudinally extending recesses (38', 38", 38"') in a seal-shaping module (12); and moving the tool (10) longitudinally through the lock chamber (3), whereby the sealing material is shaped by the seal-shaping module (12). The distribution chamber (50) is a closed chamber inside the tool (10) and. spaced from the longitudinally extending recesses (38', 38", 38"'); and the tool (10) comprises moreover at least two distribution channels (52', 52", 52"') connecting in parallel the distribution chamber (50) to the recesses (38', 38", 38"'), the parallel distribution channels (52', 52", 52"') being fine-tuned for apportioning the flow of sealing material between the recesses (38', 38", 38"').

摘要： A method for producing a cathode bar for an electrolytic cell for aluminium smelting is described. A steel semi-product is hot rolled in such as way as to form a cathode bar (50) exhibiting a cross sectional shape composed of a semi¬ circular portion (54), a flattened portion (52), and two flanks (56) joining each side of said circular portion to the flattened portion. The width (WF) of the flattened portion is at least 1.1 times the radius (R
1 ) of the semi-circular portion, preferably about 1.5 times the radius (R
1 ) of the semi-circular portion, or more.-

摘要： The invention relates to a method for producing a metal strip having an anti-corrosion metal coating. Said method comprises the following steps: the metal strip is passed through a melt; the coated metal strip is then dried by means of nozzles projecting a gas on either side of the strip, the gas having an oxidising power lower than that of an atmosphere consisting of 4% vol. of oxygen and 96% vol. of nitrogen; and the strip is then passed through a confinement region defined, in the bottom part, by the drying line and upper faces of the drying nozzles, in the top part, by the upper part of two confinement boxes placed either side of the strip, just above the nozzles, and at least 10 cm high in relation to the drying line, and on the sides, by lateral parts of the confinement boxes, the atmosphere in the confinement region having an oxidising power lower than that of an atmosphere consisting of 4% vol. of oxygen and 96% vol. of nitrogen, and higher than that of an atmosphere consisting of 0.15% vol. of oxygen and 99.85% vol. of nitrogen. The invention also relates to a coating installation and a confined drying device (10; 20; 30) for implementing said method.
