Abstract
Patente de Invenção: <B>"BLOCO DE PRé AQUECIMENTO INFERIOR PARA USO EM APARELHO DE CHANFRADURA DE METAL"<D>. Uma montagem de bloco de pré aquecimento inferior (9) para uso com um aparelho de chanfradura de metal (5) é descrita. A montagem de bloco de pré aquecimento inferior tem um bloco inferior (38) e uma extensão (39) engatada sobre e em relação sobrejacente com uma face frontal (46) do bloco inferior. Uma saída de descarga de gás (56) é definida dentro da face frontal do bloco. A extensão pode parcialmente sobrepor a saída de descarga de gás tal que um orifício de descarga de gás (70) é definido na face frontal do bloco pela extensão. A extensão inclui uma face superior (58) que estende-se para diante da face frontal do bloco, e é rebaixada com relação a uma face superior (41) do bloco. Assim construído, quando um fluxo de gás oxidante semelhante a lâmina (82) é passado sobre as faces superiores do bloco e da extensão, respectivamente, e quando um gás combustível (85) é emitido através da saída de descarga de gás, o gás combustível é pneumaticamente comprimido entre o fluxo de gás oxidante e a face superior da extensão, tal que o gás combustível é substancialmente uniformemente distribuído ao longo do comprimento longitudinal da montagem de bloco de pré aquecimento inferior e forma um fluxo de gás combustível semelhante a lâmina uniforme (90) que fica sob e em contato com o fluxo de gás oxidante semelhante a lâmina de modo a evitar que o ar ambiente aspire para dentro do fluxo de gás oxidante e dessa forma resulta em uma superfície lisa e uniformemente chanfrada na obra de metal.
