通过数值计算和物理模拟两方面发现，在不使用外加动力的情况下，利用钢包内钢液面位置势能的弯水口注流可以在离心室内产生相当强度的旋流。
Besides the stirring forces, the swirling strength may be reinforced by using bending nozzle, which use the height potential energy of molten steel in ladle.
因此，抽气形式的有源涡控是抑制旋流、减少出口总压平均损失、改善S弯进气道出口流场的有效措施。
Hence, the method of vortex control is available for removing swirl, decreasing total pressure loss, and improving flow field in S-shaped intake.
当“U”形弯环断裂时，可将轨枕下面螺帽旋下，换上新的“U”形弯 环，即可恢复使用。
When the U-shaped bent loop is broken, the nuts under the sleeper can be screwed off and a new U-shaped bent loop can be assembled for restoring use.
