摘要
采用热轧后快冷到200～400℃→再加热至临界温度定径(或减径)→空冷的工艺生产ШХ15轴承钢管,钢管的球化退火时间显著缩短,球化后钢管的性能超过ГОСТ800-78标准要求。
IIIX15 6earinK steel tubes produced with the Process of rapid coolies to 200-400 ℃ after hot-rolling-sizing (reducing) while reheatin8 to critical temperature}then cooling in air will have much shorter globurizing time.The Properties of the tubes after globurizingare hidher than that specified by OCT800-78 standard.
