鞍钢小型厂、钢铁研究所及鞍山钢铁学院合作研究了棒材余热处理课题。于1980年10份安装了自行研制的棒材热处理装置——带有萨西洛式喷嘴的3号湍流管,用于圆钢生产。实践证明,采用这一装置,提高了圆钢合格率(尤其是提高了四项指标的合格率),在经济上有了显著 Anshan Iron and Steel Small Plant, Institute of Iron and Steel and Anshan Iron and Steel Institute of cooperation in the study of bar heat treatment issues. In 1980, 10 self-developed bar heat treatment equipment, a No. 3 turbulence pipe with a Sasilillo nozzle, was installed for round bar production. Practice has proved that the use of this device to improve the round bar pass rate (in particular, to improve the pass rate of four indicators), has a significant economic
