Description

Technical Field

[0001] The utility model relates to the technical field of nitriding furnaces, and more specifically to a nitriding furnace for processing high-speed railway couplings. Background Art

[0002] The nitriding furnace is a processing furnace for heat treatment of high-speed rail couplings. After nitriding treatment, the wear resistance, fatigue resistance and high temperature resistance of the high-speed rail coupling can be improved. When nitriding the high-speed rail coupling, it is necessary to first place the high-speed rail coupling on a tray, then lift the tray and place it inside the nitriding furnace, and then perform heat treatment.

[0003] Based on the above, the inventors have discovered that: currently, when processing high-speed rail couplings, the couplings are usually stacked and placed in a material tray for heat treatment. This method can easily cause damage to the couplings, and the heat treatment effect of the couplings is relatively poor. Therefore, in view of this, the existing structure is studied and improved, and a nitriding furnace for high-speed rail coupling processing is provided, in order to achieve a more practical purpose.
