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。
