Claims (10)
- 외부동체(1)와 외부동체내에 위치하는 세라믹 물질로된 내부동체를 포함하는 용융금속 속으로 가스를 주입하기 위한 가스주입구에 있어서, 이 가스주입구가 외부동체(1) 내부에 가스투과성 유통공간(3)을 갖고 있고 이 유통공간(3)은 그 마모 방향을 따라서 상이한 기하학적 형태를 갖고 있으며 가스 유통공간을 통한 식별가스의 유통중에 마모상태에 해당하는 상이한 기하학적 형상이 가스 유통체의 표면에서 보이도록 된 가스주입구.
- 청구범위 1항에서, 전기한 유통공간(3)이 외부동체(1)와 외부동체내에 삽입된 내부동체(9) 사이의 공간부(4,6,7)에 형성되었음을 특징으로 하는 가스주입구.
- 청구범위 2항에서, 전기한 공간부(4,6,7)가 길이방향으로 동일한 폭으로 연속되게 형성되었음을 특징으로 하는 가스주입구.
- 청구범위 1항에서, 가스 유통공간(3)이 외부동체(1) 내부에 삽입된 가스투과체에 형성됨을 특징으로 하는 가스주입구.
- 청구범위 1항에서, 외부동체(1)가 철제외피(10)로 구성되고 내부동체는 상부동체(11) 및 하부동체(12)로 구성되었으며 유통공간(3)은 철제외피(10)와 상부동체(11) 사이의 공간부(13) 및 상부유통체(11)와 하부유통체(12) 사이의 공간부(18)에 형성됨을 특징으로 하는 가스주입구.
- 청구범위 2, 3, 4항중의 한 항에서, 마모상태가 유통공간(3)으로 주입되는 가연성가스의 연소화염의 기하학적 형태변화로 식별되게 되었음을 특징으로 하는 가스주입구.
- 청구범위 5항에서, 마모상태가 유통공간(3)으로 주입되는 냉각가스의 냉각작용에 의하여 외부동체(1)를 구성하는 철제외피(10)에 나타나는 어두운 부분의 위치와 형상에 의하여 식별되게 되었음을 특징으로 하는 가스주입구.
- 외부동체(1)와 외부동체내에 위치하는 세라믹 물질로된 내부동체를 포함하는 용융금속이 수용된 야금 용기속으로 가스를 주입하는 가스주입구의 마모상태를 식별하는 방법에서, 이 방법이 가스주입구의 외부동체(1) 내부에 형성된 가스 유통공간(3) 속으로 식별가스를 주입하고 식별가스에 의하여 가스주입구의 외부에 나타나는 형태에 의하여 마모정도를 식별하게 되었음을 특징으로 하는 방법.
- 청구범위 8항에서, 주입구의 가스 유통공간(3)이 마모방향으로 상이한 기하학적 단면 형상을 갖고 있고 주입되는 식별가스는 가연성가스이며 마모상태의 식별을 가연성가스의 연소에 의하여 주입구 표면에서 분출되는 화염의 형태에 의하여 이루어지게 되었음을 특징으로 하는 방법.
- 청구범위 8항에 있어서, 주입구가 철제외피(10)로 된 외부동체(1), 외부동체내의 상부동체(11) 및 하부동체(12)로 구성되고 가스 유통공간(3)은 철제외피(10)외 상부동체(11) 사이 및 상부동체(11)와 하부동체(12)사이에 형성되며 식별가스는 냉각가스이고, 마모상태의 식별은 냉각가스에 의한 철판의 냉각에 의하여 나타나는 검은 부분으로 이루어짐을 특징으로 하는 방법.
