摘要： In a thermal or thermochemical treatment, metal workpieces together with a metal guide are arranged on a batch carrier. The present invention relates to a device for flow guidance for metallic pieces during such thermal or thermochemical treatment and quenching, as well as methods using the same. The fluid guide particularly ensures a uniform cooling of an inner and/or outer lateral surface of the workpieces during the quenching process.
