5)  recirculation flow rate
循环流量
1.
While the immersion tubes are located eccentrically,larger eddies appear near the down immersion tube at the bottom of vacuum chamber,under free surface of vacuum chamber and in ladle,but no obvious effect on the recirculation flow rate was observed.
数值结果表明,偏心移动浸渍管时,在真空室底部、真空室及钢包钢液表面的下降管处发现较大的漩涡,但对循环流量影响较小;减小浸渍管间距,真空室左侧壁面的回流增强,循环流量减小;减小浸渍管插入深度,循环流量增大。

According to the low carbon steel production data acquired in the practical production in Ma'anshan Iron & Steel Works from January to June 2006 the RH circulation flow and circulation coefficient are calculated and their effects on end point carbon content analyzed as well.
根据马鞍山钢铁公司2006年1~6月低碳钢实际生产数据,计算并分析了RH的循环流量、循环系数对处理终点钢中碳含量的影响,分析得出,为了达到处理终点钢中w(C)<0。
补充资料:循环流化床
分子式:
CAS号:

性质:在气速大于颗粒的自由沉降速度下进行流化,颗粒被气流带出,把气体与固体分离后,固体又循环回床层中所构成的流化床。它在工业上有很多用途。例如用于催化裂化,催化剂在提升管中被重油蒸气流化并输送,同时发生反应。在提升管顶部失活的催化剂与油气分离后进入另一个流化反应器(再生器),被空气流化并进行再生。再生后的催化剂又循环回提升管,构成一组循环流化床的催化裂化反应器。
