热轧无缝钢管在线常化工艺

PROCESS FOR ON-LINE NORMALIZATION OF HOT-ROLLED SEAMLESS STEEL TUBES

介绍了热轧无缝钢管在线常化工艺的特点及应用要求。与传统常化工艺相比,在线常化工艺具有工艺简单、设备投资少、能耗低等优点。该工艺适用于连续轧管,自动轧管等工艺。

The co-authors describe the features and application requirements with respect to the on-line normalization process for hot-rolled seamless steel tubes,compared with the conventional processes in this regard, the said normalization process features such advantages as technological simplicity, less investmont in equipment, less energy consumption and so forth. The process is applicable for certain pipe rolling processes, for instance, mandrel mill and plug mill lines.
