摘要： A sintering furnace can have a housing, one or more heating elements, and a conveying assembly. Each heating element can be disposed within the housing and can subject a heating zone to a thermal shock temperature profile. A substrate with one or more precursors thereon can be moved by the conveying assembly through an inlet of the housing to the heating zone, where it is subjected to a first temperature of at least 500° C. for a first time period. The conveying assembly can then move the substrate with one or more sintered materials thereon from the heating zone and through an outlet of the housing.

摘要： A tunnel oven and associated method for the heat treatment of friction elements, and in particular braking elements such as brake pads is provided. The friction elements are arranged on a resting surface of a conveyor device, are moved between an inlet opening and an outlet opening of the tunnel oven, and are heated by irradiation by at least one heating device. The heating device includes a radiating plate made from stainless steel arranged facing the conveyor device and heated by electromagnetic induction using at least one inductor arranged facing the radiating plate and spaced apart therefrom on the side opposite to the conveyor device. A cooling air flow for the braking elements between the resting surface and the radiating plate is directed in counterflow to a feeding direction of the conveyor device.

摘要： A heat treatment apparatus 1 includes a coolant passage defining body 42 to define a coolant passage 48 to supply a coolant to a workpiece 100. The coolant passage defining body 42 includes an upper member 50 and a lower member 40 as a plurality of coolant passage defining members, and is configured so that, by displacing these members 49 and 50 so as to approach each other along an up-down direction Z1 crossing a conveyance direction, the coolant passage 48 is defined in a state housing the workpiece 100. In addition, the coolant passage defining body is configured so that, by displacing the members 49 and 50 described above so as to separate from each other along the up-down direction Z1, the workpiece 100 is allowed to be let into and out of the coolant passage 48 along the conveyance direction A1.
