    摘要: A system thermally treats rails. The system has a cooling device for spraying a cooling medium onto a rail to be treated. The cooling device defines a cooling path for receiving the rail to be treated. A conveyor moves the rail to be thermally treated through the cooling path. A vertically displacing device for displacing at least one of the cooling devices for adjusting a position of the one cooling device relative to the rail to be treated.

    摘要: A superior unitary one quarter mile long railroad rail and system and method for manufacturing the same. The method of manufacture is characterized by the use of a continuous rolling process and the in-line controlled cooling of the rail. The long railroad rail is rolled in a single direction with a plurality of in-line rolling stations.

    摘要: A method for producing a steel section by a rolling process including a rough rolling step, an intermediate rolling step and a finishing rolling step. The intermediate rolling step comprises water-cooling the flange portion of the rough-rolled steel section between rolling passes in the intermediate rolling step to cool the surface layer of the flange to a temperature not higher than 750.degree. C., and rolling the flange portion during recuperation of the surface layer of the flange at least one time between the rolling passes with a total draft not less than 20% and at an average rolling temperature not higher than 950.degree. C. and, after the finishing rolling step the outer surface of the flange is cooled at a cooling rate ranging from 0.5.degree. to 10.degree. C./sec depending on the thickness of the flange. Also the carbon equivalent of the steel is controlled. The advantage is that steel sections of various contours and dimensions can be produced from minimized varieties of steel compositions.

    摘要: The spray unit lies downstream, in-line with an extrusion press and serves to cool metallic sections in particular sections of aluminum or an aluminum alloy from all sides. The cooling medium emerges from spray nozzles program-controlled in the direction of the section. The distance, the cross-section distribution and the direction of the spray nozzles are adapted specific to the geometrical shape and distribution of mass in the section. The optimum parameters are determined and stored in the unit processor. The spray nozzles are arranged in nozzle beams running in the direction of the extruded section. The nozzle beams comprise at least one longitudinal water channel and two longitudinal air channels, whereby cross-intersecting channels branch off from the water channels to the spray nozzles and the air channels terminate in air gaps which are directed towards the nozzle outlets.The extruded sections are passed through the spray unit and cooled, at a rate that exceeds the critical cooling rate specific to the material, by a program-controlled, sprayed cooling medium in a manner that takes into account the shape of the section and the distribution of mass in the section. Using uniform cooling on all sides, sections that are extruded straight can be kept straight, while sections that are distorted on extrusion can be corrected with respect to bending and/or twisting by non-uniform cooling.

    摘要: Cooling apparatus for cooling metal sections comprises a series of sprayers for simultaneously spraying a mixture of liquid and gas. Each sprayer has a gas inlet at one end and a mixture outlet at the other end. One or more liquid inlets are provided between two distinct peripheral shoulders. An elongate gas-supply manifold has outlet orifices adapted to seat the gas-inlet-side shoulders of the respective sprayers in a gas-tight manner. An elongate liquid-supply manifold has outlet orifices adapted to seat the mixture-outlet-side shoulders of the respective sprayers in a liquid-tight manner.
