軸向水流噴射速度對(duì)鋼管內(nèi)表面冷卻均勻性的影響

Research into Influence by Axial Jet Velocity on Cooling Uniformity of Steel Pipe Inner Surface

摘要: 利用有限元耦合場數(shù)值模擬計(jì)算方法,對(duì)無縫鋼管控制冷卻過程進(jìn)行了三維建模和數(shù)值模擬,研究了軸向水流噴射速度對(duì)無縫鋼管內(nèi)表面軸向和周向冷卻均勻性的影響規(guī)律。結(jié)果表明,隨著軸向水流噴射速度的增加,無縫鋼管軸向溫度逐漸降低,軸向各點(diǎn)溫度更趨于均勻且變化規(guī)律相同,但周向各點(diǎn)溫度均勻性變差。

Abstract: With the coupled field finite element method,a 3-D model for the controlled-cooling process of seamless steel tubes is set up,and then relevant numerical simulations are generated to study the law related to the influence by the axial jet speed on both arial and circumferential cooling uniformity of the steel pipe inner surface.The results show that along with the increase of the axial jet speed,the axial temperature of the pipe decreases,while the temperatures at the points of the pipe in the axial direction tend to be more uniform,and the temperature variations are the same,but uniformity of the temperature at each circumferential point becomes worse.
