摘要： Quench plug systems and their use in heat treating a workpiece. The quench plug system includes a tapered plug having a longitudinal core axis and a mandrel configured to be interposed between the tapered plug and the workpiece. The tapered plug is configured to allow the mandrel to translate along the core axis of the tapered plug when the workpiece is heated.

摘要： Iron-based alloys and articles in strips, sheets, workpieces and the like are converted into high strength steel with a minimum of cost, time and effort, including producing dual phase materials. This is achievable by extremely rapid micro-treating of low, medium, and high carbon iron-based alloys and articles by rapid heating and rapid cooling at least a portion of the alloy/article. This heating step involves nearly immediately heating the iron-based alloy to a selected temperature above its austenite conversion temperature. Then, the alloy is immediately quenched, also at an extremely fast rate, on at least a portion of the iron-based alloy in a quenching unit adjacent the heating unit. This procedure forms high strength alloy in a desired area, depending upon where the treatment was performed.

摘要： Multi-chamber furnace for vacuum carburizing and quenching of gears, shafts, rings and similar components has at least two process chambers connected in parallel, with a continuous feeding mechanism for individual workpieces. Those chambers—the first one being a heating chamber, the second being a carburizing chamber and the third one diffusion chamber—are configured in a vertical arrangement, placed in a shared vacuum space with gas-tight division, whereas at the ends of each chamber there are incorporated heating chambers with thermal insulation, with a graphite heating system and stepping feeding mechanism incorporated in the core for the purpose of continuous feeding of individual workpieces. At the ends of those chambers the construction incorporates transport chambers featuring loading and unloading systems X-Y enabling cooperation with individual process chambers through thermal and gas-tight doors installed in chamber ends, while external access to the transport chambers is ensured through loading and unloading locks.

摘要： A rapidly quenched Fe-based soft-magnetic alloy ribbon having wave-like undulations on a free surface, the wave-like undulations having transverse troughs arranged at substantially constant intervals in a longitudinal direction, and the troughs having an average amplitude D of 20 mm or less, is produced by a method comprising (a) keeping a transverse temperature distribution in a melt nozzle within ±15° C. to have as small a temperature distribution as possible in a melt paddle of the alloy, and (b) forming numerous fine linear scratches on a cooling roll surface by a wire brush, thereby providing a ground surface of the cooling roll with an arithmetical mean (average) roughness Ra of 0.1-1 μm and a maximum roughness depth Rmax of 0.5-10 μm.

The gear is induction heat treated at a first portion of the gear and a second portion of the gear remains untreated by induction hardening. The gear has an inner surface. The inner surface includes the first portion and the second portion. The first portion has a first width. The second portion has a second width. The inductor coil includes at least one heating loop and at least one non-heating loop. The inductor coil is energized to a predetermined frequency to create an alternating magnetic field, where the alternating magnetic field developed in the heating loop induces an eddy current in the first portion of the gear.

摘要： A quench system for applying cooling air to one or more hot metallic components that are supported on a component support having a substantially open construction. The quench system includes a housing having sidewalls that define a cooling chamber with peripheral portions proximate the sidewalls and a center portion spaced inwardly from the sidewalls. The quench system also includes a conveyance system that is configured to carry the component support into the center portion of the cooling chamber, as well as a forced air fan that generates a bulk flow of cooling air through the cooling chamber. The quench system further includes a plurality of nozzle baffles extending inwardly from the plurality of sidewalls to define a narrowing region within the housing between the forced air fan and the conveyance system, whereby, during operation of the fan, cooling air flowing through the peripheral portions of the cooling chamber is redirected into the center portion of the cooling chamber.

摘要： A system for producing components by hot stamping includes a laser cutting station for cutting a plate from a supplied steel-sheet material. The plate has at least one of a predetermined edge-contour and a predetermined cut-out portion for forming a shape of the component. The plate is stored in a storage station, and is subsequently transferred to a furnace station for heating the plate to a predetermined deformation temperature. A press having a hot stamping tool forms the plate into the shape of the component. The system also includes a measuring station disposed downstream of the press for obtaining measurement data relating to the shape of the component that is formed from the plate. The measurement data obtained using the measuring station is provided to a control module of the laser cutting station via a feedback loop.

摘要： The invention relates to a method and to an apparatus for producing pipes made of steel. According to the invention, within a period of time of no more than 20 seconds after the last deformation at a temperature greater than 700° C., but less than 1050° C., during passage a cooling medium is applied with elevated pressure onto the outside circumference of the pipe over a length of greater than 400 times the pipe wall thickness in a quantity which during rapid cooling provides an equivalent cooling speed of greater than 1° C./second of the pipe wall over the pipe length to a temperature in the range of 500° C. to 250° C., whereupon further cooling of the pipe down to room temperature is carried out by exposure to air.
