Abstract

"CONEXãO ROSCADA PARA COLUNAS DE ELETRODO DE CARBONO E/OU GRAFITE". A invenção refere-se a uma conexão roscada que está garantida contra afrouxamento/desrosqueamento para as colunas de eletrodos de carbono e/ou grafite. Os eletrodos estão conectados em colunas com elementos de conexão roscados, isto é, os pinos de conexão de carbono. Pelo menos uma peça tem uma rampa em cunha na raiz da etapa de rosca. Quando os componentes da conexão roscada são rosqueados juntos, as cristas das etapas de rosca de uma peça topam com as rampas em cunha do outro componente de conexão roscado. Uma linha de contato é criada, possivelmente múltiplas seções de uma linha de contato. Quando as peças são rosqueadas juntas, todas as forças são transferidas de uma peça para a outra somente através da linha de contato. Em um caso especial, o contorno da etapa de rosca ao longo de cuja raiz a rampa em cunha está correndo é reduzido, por exemplo, para uma linha de conexão entre duas rampas em cunha localizadas uma acima da outra na seção transversal.
