The vacuum carburizing temperature is generally higher than that of ordinary gas carburizing. Carburizing and diffusion are often used at 920~1040 C. As shown, there are two stages: pulse ventilation, stop gas, multi-stage carburizing and diffusion. The effect is better. Vacuum carburized layer is formed faster than ordinary gas, liquid and solid carburized layer because of its high temperature, especially its clean surface and high activity. If the carburized layer needs 1 millimeters, it will take 927 hours and 1 hours at 1033 degrees Celsius, only 5 hours.
Precision steel pipe has the advantages of no oxide layer on the inner and outer walls, high pressure, no leakage, high precision, high finish, small cold bending deformation, high flatness, no cracks and so on. It is mainly used to produce pneumatic or hydraulic components. As a cylinder or an oil cylinder, it can be a seamless tube. The chemical composition of cold drawn precision steel pipe

我们对每年无缝钢管的操作进行了认真的安排。前瞻性行业研究所《中国无缝钢管产业发展前景预测与改造升级分析报告》数据显示，2014年我国共生产无缝钢管313702万根，比上年增长5930万根#同比增长0.19%，比去年同期增长13.67%，下降13.48个百分点。无缝钢管表观消耗量263313万_比上年减少8730万_比上年增长16.92％减少0.33％，减少17.25个百分点。占企业入伙总数的%。
Precision steel pipes are mainly used to produce seamless or welded products such as pneumatic or hydraulic components, such as cylinders or cylinders, because of their advantages such as no oxide layer on the inner and outer walls, high pressure, no leakage, high precision and so on. SH, no cold bending deformation, flat and no crack. Precision steel pipe mainly produces 10, 20, 35, 45, 40 cr, 42CrMo grade precision seamless steel pipe can also be consulted and supplied.
At heating time (s) = KD, D is the thickness of the workpiece, mm, K as the coefficient, and the factory data. (3) cooling. Different cooling systems are used for different tissues. It is usually cooled in static air. If the workpiece is large, it can be cooled by blowing or fog. The length is usually也许正是因为这个原因，在过去相当长的时间，另一方面，虽然有关各方已提出了许多警告，产能过剩的钢铁行业，甚至进行产业结构调整，地方政府仍然回避了铁和ST通过“变为零”等政策的对策就是鳗鱼项目；同时，为了维护相关的钢铁产能对地方GDP的贡献，有些地方还不遗余力地支持当地落后产能项目日即使他们清楚地知道一些地方钢铁项目的产量明显落后，政策倾斜。
