Accelerated run-out table cooling has become a key technology that determines microstructure and resulting mechanical properties of thermo-mechanically controlled processed (TMCP) steels. The present study quantifies the heat transfer mechanisms during bottom jet cooling of a stationary steel plate with systematic pilot-scale experiments. The emphasis of the study is to quantify the effect of process parameters, i.e. jet impingement velocity, water temperature and nozzle orientation, on heat extraction rates. Experimental results are described and quantitatively analyzed, adding to the database for run-out table cooling.

钢的瞬态底部射流冲击冷却

加速跳动工作台冷却已成为一项关键技术,它决定了热机械控制加工(TMCP)钢的微观组织和所产生的机械性能。本研究通过系统的中试规模实验对固定钢板底部射流冷却过程中的传热机理进行了量化。该研究的重点是量化工艺参数(射流撞击速度,水温和喷嘴方向)对吸热率的影响。描述并定量分析了实验结果,并将其添加到数据库中以用于耗尽表冷却。
