Well quenching furnace: Quenching is the metal workpiece heated to an appropriate temperature and maintained for a period of time, and then immersed in a cold medium for rapid cooling of metal heat treatment process.

Well quenching furnace is the national standard energy-saving periodic operation well furnace, heat treatment or quenching temperature 850-1200℃, mainly for shaft workpiece, rod workpiece, roll, 45 steel, stainless steel and other metal materials and mechanical parts of the quenching heat treatment, vertical lifting quenching heating, workpiece is not easy to deform, but also for mechanical parts annealing, hot treatment.

Categories:

Well type quenching furnace is commonly used in atmosphere protected well type quenching furnace and ordinary well type quenching furnace, and its quenching medium is mineral oil, water, air and so on.

Well type quenching furnace is widely used in various molds, rods, long shafts and parts requiring surface wear resistance such as gears, rolls, etc.

Structure:

The shell of the furnace body of the well type quenching furnace is welded into a frame structure with steel and steel plates, and the opening and closing of the furnace cover can be lifted by electric or manual pole. Lining: can be made of firebrick or full fiber structure. Heating element: The heating element is spiral, uniformly placed on the joist brick around the furnace, and the resistance wire is positioned with the shaped joist brick. The material of the heating element is Ocr27AL7MO2 and the operating temperature is 1100℃.

First, the ordinary well quenching [1] furnace mouth using the furnace mouth retainer, the purpose is to use the Lei hook the workpiece frame and protect the furnace mouth from being damaged by the workpiece, so that the heat is not lost, so as to ensure the uniformity of the furnace temperature. Quenching can improve the hardness and wear resistance of metal workpiece, through quenching and tempering at different temperatures called tempering heat treatment, can greatly improve the strength of metal, toughness and fatigue strength, and can obtain the combination of these properties (comprehensive mechanical properties) to meet different requirements.

2, atmosphere protection Well quenching furnace (well gas carburizing furnace [2]) in the furnace cover furnace fan: to stir the atmosphere in the Muffle tank and make it uniform, while making the furnace temperature tend to be uniform. There are also three process tubes on the furnace cover leading to the Muffle tank of the furnace: a sleeve top is installed with three stainless steel dispensers, from which the three drops inject methyl alcohol, kerosene or other organic liquids into the furnace, and all kinds of liquids can be adjusted.
