Description
Claims (4)
- 첨가제와 결합할 원소를 함유하는 금속 융체를 용기에 충전하고 용기내에 벽으로 형성된 방안으로 적어도 하나의 첨가제를 공급하고, 상기 벽에 형성된 구멍을 통해 금속 융체를 상기 방안으로 도입하여 방내의 첨가제를 증발시키고, 증발된 첨가제가 상기 구멍을 통해 용기내의 금속 융체내로 흐르도록하는 금속 융체내로의 첨가제 증발 방법에 있어서, 금속 융체의 양 T(톤), 첨가제와 결합될 금속 융체내의 원소에 대한 상기 방의 형태 및 크기, 상기 구멍의 총단면적 상호간의 관계에 따라 증발시간 t(초)를 결정하며, 상기 증발시간 t를 식 t=68×T0.22×A(A는 증발될 첨가제에 따라 선택되는 계수)에 의해 구하여 조절하는 것을 특징으로 하는 금속 융체내로의 첨가제 증발방법.
- 제 1 항에 있어서, 상기 첨가제가 마그네슘이고, 계수 A를 0.5∼1.5의 범위로 조절하는 것을 특징으로 하는 금속 융체내로의 첨가제 증발방법.
- 제1함에 있어서, 상기 첨가제가 칼슘이고, 계수 A를 0.7∼1.2의 범위도 조절하는 것을 특징으로 하는 금속 융체내로의 첨가제 증발방법.
- 제 1 항에 있어서, 상기 첨가제가 리튬이고, 계수 A를 0.4∼1.1의 범위로 조절하는 것을 특징으로 하는 금속 융체내로의 첨가제 증발방법.
