Claims (3)
- 제강공정에 있어 출강초기 출강구를 통하여 초기 수강래들로 슬래그가 유출되는 것을 방지하기 위한 플러그에 있어서,원뿔형상으로 구성되데, 일측에는 세라믹 캡을 고착시키고, 타측에는 스컷트형 세라믹 링이 부착되어지는 본체와;출강초기 전로를 경동할 때 상기 본체를 고온에 견디는 단열 피복재로 도포하여 상기 출강구에 삽입함으로서 슬래그층이 출강구를 통과할 때까지 스커트형 세라믹 링에 의하여 수강래들로 유출되지 않도록 하며, 상기한 플러그 본체 상부에 슬래그가 유입될 때 슬래그에 의해 플로그 상부가 조기 용융되지 않도록 상기 스컷트형 세라믹 캡을 고정시켜 이루어진 것을 특징으로 하는 전로의 출강구 플러그.
- 제1항에 있어서, 상기 본체를 철판으로 구성하고 그 철판표면에 고온에 견디는 단열피복재인 금속산화물 세라믹을 도포하고, 상기 본체하단에 경량의 세라믹재질로 제작된 스컷트형 세라믹 캡을 고착시킨 것을 특징으로 하는 전로의 출강구 플러그.
- 제1항에 있어서, 상기 플러그가 상기 출강구를 보다 견고히 밀착되도록 하기 위하여 프러그 몸체(50d)의 단부에 철피캡(50a-1)을 내부로 삽입하여 그 캡에 의해 몸체의 외압에 견디도록 함과 동시에 몸체의 외부로 소정의 압력이 가해지도록 한 것을 특징으로 하는 전로의 출강구 플러그.
