Abstract: 본 발명은 케이알 설비용 임펠러에 관한 것으로, 레이들에 수강된 용선에 침지된 상태로 회전하여 상기 용선을 교반하는 임펠러에 있어서, 회전축을 중심으로 대칭 형성되고 관통 홀이 형성된 주익과, 상기 대칭 형성된 주익 사이에서 회전축을 중심으로 대칭 형성된 보조익을 포함하는 케이알 설비용 임펠러가 제공된다. 이에 따라서, 주익과 보조익에 형성된 블레이드에 의해 레이들 내의 용선을 활발하게 교반할 수 있고, 특히 주익에 형성된 관통 홀에 의하여 레이들 상부 용선과 하부 용선을 더욱 활발히 교반할 수 있는 효과가 있다.
