    摘要: A first nitriding process step is performed in which a steel member is subjected to a nitriding process in a nitriding gas atmosphere having a nitriding potential with which a nitride compound layer having a γ′ phase or an e phase is generated, and thereafter a second nitriding process step is performed in which the steel member is subjected to a nitriding process in a nitriding gas atmosphere having a nitriding potential lower than the nitriding potential in the first nitriding process step, to thereby precipitate the γ′ phase in the nitride compound layer. It is possible to generate the nitride compound layer having a desired phase mode uniformly all over a component to be treated and to manufacture a nitrided steel member high in pitting resistance and bending fatigue strength.

    摘要: The invention relates to a roller hearth furnace for the heat treatment of coated metal sheets as well as to a corresponding method. The objective of the invention is to put forward a roller hearth furnace that allows the alternating processing of AlSi-coated metal sheets and metal sheets with zinc alloy coatings for hot-working, whereby considerably less effort is involved for the alternating procedure than is the case in the state of the art. The roller hearth furnace according to the invention for the heat treatment of coated metal parts is characterized in that it has at least a first zone and a second zone, whereby in the first zone, a temperature below the melting temperature of the AlSi deposits or a temperature of more than approximately 900° C. [1652° F.] can be maintained, whereas in the second zone, a temperature of more than approximately 870° C. [1598° F.] can be reached.

    摘要: An inventive automated heat treatment system has a furnace for heat treating forged engine valves, a carry-in mechanism for transporting the forged valves into the furnace, and a carry-out mechanism for transporting heat treated valves out of the furnace. Each of the carry-in mechanism and the carry-out mechanism has a retention mechanism for retaining valves hung, and a transport mechanism for transporting valves to the furnace as they are hung. The furnace has heating means, groups of paired rails for supporting and moving the valves hung in the furnace, and a stopper for controlling the positions of the valves on the rails. The engine valves are maintained hung with their umbrella-shaped portions supported by the respective mechanisms throughout the automated heat treatment processes. Thus, the heat treatment of engine valves is done in a fewer steps than in a conventional system.
