[0002] Vacuum high-pressure gas quenching furnaces are highly advanced vacuum heat treatment equipment, primarily used for the heat treatment of metallic materials. Their principle involves using high-pressure gas to quench metallic materials, thereby altering their microstructure and properties. Their superior performance and unique design make them widely applicable for vacuum bright gas quenching, annealing, sintering of magnetic materials, and rapid cooling of high-precision parts made from alloy materials such as high-speed steel, mold steel, stainless steel, alloy steel, and titanium alloys.

[0003] However, when the existing materials are heated, one side of the workpiece is placed on the tray. When it is heated, the bottom of the workpiece is always in contact with the top surface of the tray, causing the tray to absorb some heat. This reduces the cooling rate of the metal in the covered area, thus affecting the quenching effect. It also makes the workpiece prone to uneven heating and deformation, which can easily reduce the quality of the workpiece. Utility Model Content
