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。
Compared with solid steel such as round steel, seamless steel tube has the same bending and torsion strength and light weight. It is an economical steel. It is widely used in the manufacture of structural mechanical parts such as oil drill pipe, automobile transmission shaft, bicycle frame, steel scaffolding for construction. The use of seamless steel pipe to manufacture ring parts can process, save materials and processing time, such as rolling bearing rings, Jack sleeves and so on. Steel pipes are also indispensable materials for various conventional weapons, such as pipes, guns and so on. According to the shape of the section area, the steel pipe can be divided into circular pipes and special-shaped pipes. Because the circumference is equal and the circular area is large, the circular tube can transport more fluid. In addition, the ring section under the action of internal and external radial pressure, the force is more uniform, so most of the steel pipes are circular.
