喷头结构对顶吹转炉冶炼有较大的影响。例如大中型转炉采用多孔喷头,仅由于从一股射流变为多股氧射流,便在减少喷溅、提高转炉效率等方面取得了显著的成绩。值得注意的是,不少转炉车间反映,有时甚至多孔喷头的喷孔直径和夹角发生微小变化,例如由于加工误差或氧枪装配中造成的某些差别,也会使喷枪在吹炼效果上有所谓“好用”与“不好用”的不同。这当然也是氧射流本身有了改变的结果。因此,对于 Nozzle structure of the top blown converter smelting have a greater impact. For example, medium- and large-sized converters with multi-hole nozzles have made remarkable achievements in reducing splashing and improving the efficiency of the converter, etc., simply by converting from one jet to multiple streams of oxygen. It is noteworthy that many converter rooms reflect, and sometimes even minor nozzle hole diameter and angle changes occur, for example, due to processing errors or oxygen gun assembly caused some of the differences, but also make the gun blowing effect The so-called “easy to use” and “not easy to use” different. This is of course the result of a change in the oxygen jet itself. So for
