During the heat treatment of long shaft parts, the following problems have always existed：

1. The workpiece at 800 ℃ ~ 900 ℃ is completely exposed to the air and transferred to the oil quenching tank or cooling device, resulting in serious oxidation and decarburization of the workpiece 久久国产精品成人影院.

2 2019中文字幕在线观看视频. High temperature workpieces cause great radiation pollution to the environment.

3. Extremely prone to fire

4 人妻精品久久一区二区av. The quenching transfer time of large workpieces needs to be controlled manually, which is greatly affected by human factors.

5. When several tons or even tens of tons of workpieces above 800 ℃ enter the oil quenching tank, the high-temperature workpieces heat and evaporate a large amount of oil vapor, produce a flame several meters to more than ten meters high and emit a large amount of oil fume, which is very harmful to the environment 99久久久国产精品免费牛牛四川.

Deep well precision controlled atmosphere furnace can solve the above problems

advantage:

1 在线成人www免费观看视频. The transfer bell is used as the protection device for quenching transfer of workpieces, which greatly reduces the chance of contact between workpieces and air.

2 国产黄色视频在线播放. The modular combination can be used to design an automatic heat treatment production line according to the needs of heat treatment process, with strong process adaptability.

3. The environment of the workshop has been greatly improved because there is a nitrogen curtain to protect and isolate the air, which greatly reduces the quenching oil fume and meets the requirements of cleaner production 亚洲V无码V在线影院.

4 男女晚上黄羞羞视频播放. There is no unsafe factor caused by the swing of the workpiece during quenching and lifting and before entering the oil tank, during the movement of the workpiece and when it is aligned and positioned into the oil tank;.

5 东京热无码视频. The heat treatment process is controlled by computer and produced automatically and mechanically to reduce the impact of human factors on the heat treatment quality. The operation is safe and reliable. The process reproducibility of the workpiece is high, and the heat treatment quality of the workpiece is stable and consistent.

Scope of application:

It is used for heat treatment quenching and carburizing quenching of large long shafts in power generation equipment, shipbuilding, rail transit, wind power, offshore engineering, heavy mining equipment and other industries 麻豆av在线播放. It is a major basic equipment in the machinery industry. It plays a positive role in improving the product quality of large long shafts and slender rod parts, and also plays a positive role in the later large generator rotors, large ship crankshafts, long shaft and large tooth workpieces.
