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.

山东大鼎金属材料有限公司The rolling effect of steel and copper is better, while the effect of cast iron is poor. The rolling effect of malleable cast iron and ductile iron is better than that of gray cast iron. When the hardness of cast iron is Therefore, it is not suitable to use rolling technology when the casting surface is short and the cold-drawn precision steel pipe can save steel, improve processing efficiency and save energy. The so-called high-precision cold-drawn pipe refers to the main technical indicators of the high-precision cold-drawn pipe produced by this technology, which has the characteristics of dimensional accuracy (tolerance range), surface finish, roundness, straightness, wall thickness uniformity, etc., and meets or exceeds the requirements.山东大鼎钢管厂结构用不锈钢无缝钢管（GB/T14975-1994）是广泛用于化工、石油、轻纺、、食品、机械等工业的耐腐蚀管道和结构件及零件的不锈钢制成的热轧（挤、扩）和冷拔（轧）无缝钢管。流体输送用不锈钢无缝钢管（GB/T14976-1994）是用于输送流体的不锈钢制成的热轧（挤、扩）和冷拔（轧）无缝钢管。内容简介:本标准规定了输送流体用无缝钢管的订货内容 耐高温吊秤注意事项可以打印完备的称重数据并可按日期该材料柔软、塑性好，易于轧制。

Chemical heat treatment is to heat the workpiece containing carbon, nitrogen and other alloy elements in the medium (gas, liquid, solid) for a long time, so that the surface of the workpiece to form carbon, nitrogen, boron, chromium and other elements. After infiltration, some other heat treatment processes, such as quenching and tempering, are sometimes needed. The main chemical heat treatment is carburizing, nitriding and metallization.
It is precisely because of the emergence of seamless steel pipe that these high-pressure gas and liquid transportation problems have been solved, so that people can really make life so fast and convenient. Many factories have expanded the scale of production, and seamless steel tubes, like factories, have been used for high transportation.
