Description

전자 교반방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 방법을 실시하는 전자유도자의 횡단면도, 제2도는 제1도의 전자 유도자의 변형예의 횡단면도, 제3도는 제1도의 전자 유도자의 또 다른 변형예는 횡단면도.

Claims (5)

  1. 내부공간을 형성한 전자유도자가 그 전자 유도자의 내부공간의 내벽에 서로 대항하는 복수쌍의 자극을 설치하고, 전원장치에 의해서 상기 자극의 극성을 순차적으로 회전시킴으로써 전자 유도자의 내부공간을 통과하는 용융금속의 횡단면내에 복수의 회전류를 발생시키는 것을 특징으로 한 전자 교반방법.
  2. 제1항에 있어서, 상기 전자유도자가 닫힌 요우크로 구성되는 특징으로 한 전자 교반방법.
  3. 제1항에 있어서, 상기 전자유도자가 개방되는 요유크로 구성되는 것을 특징으로 한 전자 교반방법.
  4. 제1항에 있어서, 상기 자극이 대각선상에 배열되어 있는 것을 특징으로 한 전자 교반방법.
  5. 서로 간격을 두고 독립한 2개의 전자유도자를 설치하고, 상기 전자유도자간에 소정의 내부공간을 형성하고, 그 내부공간내벽에 서로 대향하는 복수쌍의 자극을 설치하여 전원장치에 의하여 상기 자극의 극성을 순차적으로 회전시킴으로써, 상기 전자 유도자의 내부공간을 통과하는 용융금속의 횡단면내에 복수의 회전류를 발생시키는 것을 특징으로 한 전자 교반방법.
