摘要： An apparatus for continuously treating metal strip of aluminum, an aluminum alloy, a nonferrous metal, or a nonferrous-metal alloy, has at least one heat-treatment device through which the metal strip passes in a strip-travel plane in a travel direction without contact from an upstream inlet end to a downstream outlet end and having a heating zone at the upstream end and a cooling zone formed by a row extending in the direction of at least two cooling subzones. A strip-centering device between the cooling subzones adjusts a position of the metal strip in the strip-travel plane and transverse thereto.

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： A wire heating system includes an induction heating apparatus having a power supply and an induction coil arranged to heat a wire rod by an induction heating using current supplied from the power supply, and a controller configured to control the current to be supplied to the induction coil based on a feeding speed of the wire rod. The induction heating apparatus has a heating section in which the wire rod is heated by the induction heating using the induction coil, and a soaking section located downstream of the heating section to homogenize the temperature distribution of the induction-heated wire rod. The controller is configured to control the current to be supplied to the induction coil such that a temperature of the wire rod at a downstream end of the soaking section becomes a target temperature.
