用雾化法生产金属粉末时,惰性气体将熔融状态的金属流喷入容器中。为了增加被雾化的金属与容器壁的碰撞次数,提高被雾化金属的冷却速度,让雾化的熔融金属流在容器内受到由容器下部惰性气体切向气流所产生的旋涡作用。
When atomizing the metal powder, the inert gas injects the molten metal stream into the container. In order to increase the number of collisions between the atomized metal and the container walls and to increase the cooling rate of the atomized metal, the atomized molten metal stream is subjected to swirling within the container by the tangential flow of inert gas from the lower portion of the container.
