Oil quenching causes surface deterioration easily. Due to the high surface activity, significant thin layer carburization can occur under the action of short and high temperature oil film. In addition, the adhesion of carbon black and oil on the surface is not conducive to simplifying the heat treatment process. The development of vacuum quenching technology mainly lies in the development of single gas cooled quenching furnace with excellent performance. Double chamber furnace can also be used for gas quenching (front chamber air jet cooling), but the operation of the two stations makes it difficult to load a large number of furnace, and easy to cause workpiece deformation or change the direction of workpiece quenching. NG deformation during high temperature movement.
山东大鼎钢管厂公式计算钢管的理论重量：W=(D-S)＊S＊0.02466，其中W=钢管每米的重量；S=钢管的公称壁厚；D=钢管的公称外径，光亮管的表面质量i清洁、无氧化层、无裂纹、折叠、轧制、结疤、分离层和条纹。
山东大鼎金属材料有限公司The main characteristics of precision seamless steel pipe in precision steel pipe mill are: high precision, high inner and outer wall finish, no oxide layer after heat treatment, high inner wall cleanliness, high pressure bearing, cold bending deformation, flattening, no crack. It can be used for all kinds of complex deformation and machining. Steel tube color: bright white medium, high metallic luster. Precision seamless steel pipe process: high quality carbon steel, finish rolling, non-oxidizing bright heat treatment state, non-destructive testing, steel pipe inner wall with special equipment cleaning, high pressure flushing, rust-proof oil coated on the steel pipe, used for rust prevention. When installing, two end covers are used for dust prevention.山东大鼎钢管厂石油裂化用无缝钢管（GB9948-88）是适用于石油精炼厂的炉管、热交换器和管道无缝钢管。7.地质钻探用钢管（YB235-70）是供地质部门进行岩心钻探使用的钢管。8.金刚石岩芯钻探用无缝钢管（GB3423-82）是用于金刚石岩芯钻探的钻杆、岩心杆、套管的无缝钢管。
Precision steel pipe is mainly used to produce pneumatic or hydraulic components because of its advantages such as no oxide layer on the inner and outer walls, high pressure, no leakage, high precision, high finish, no deformation in cold bending, flatness and no cracks. As a cylinder or an oil cylinder, it can be a seamless tube. The chemical composition of cold drawn precision steel pipe is carbon, silicon, Si, manganese, sulfur, phosphorus, phosphorus and Cr.. The popularization and application The so-called high-precision cold-drawn pipe is characterized by strict internal and external diameter accuracy (tolerance range), good surface finish, good roundness, uniform wall thickness. Some or exceed the requirements of standard GB and standard ISO434/i-1980
2011年10月，美国应美国钢铁公司和美国钢铁工人联合会的请求，提交了反补贴案。当时，中国官员说，他们盲目地指责从中国进口产品倾销或补贴，缺乏事实依据，中国坚决反对这种做法。
对于高碳钢，正火可以重组渗碳体，促进球化。对于截面变化剧烈的大型精密钢管或铸钢件，可以采用正火代替淬火，也可以采用变形和开裂倾向，或者可以制备淬火组织。精密钢管的淬火、修复部分会受到正火和过热的影响，从而发生再硬化。
