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。

The company in line with the principle of credibility first, small profits, high sales, high quality service, flexible business model to open up the market. With the support of many new and old customers, the company has been growing and becoming a large-scale seamless steel pipe production and management company in the iron and steel industry.



山东无缝钢管厂能生产无缝钢管,使每个人都满意。而从价格的角度来看更是如此,山东无缝钢管产业链已经做得很好。由于产业链的完善,山东无缝钢管厂能够更好地控制无缝钢管的成本,能够以更低的价格卖给需要的人,所以质量好、价格低的无缝钢管必将受到大家的喜爱。
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.
