Abstract

"ELETRODOS DE CARBONO E SEUS ELEMENTOS DE CONEXãO QUE APRESENTAM SUPERFìCIES DE CONTATO DIRECIONALMENTE ESTRUTURADAS". Colunas de eletrodos feitas de carbono e grafita são atarraxadas entre si a partir de elementos individuais, por exemplo, os eletrodos e os bocais roscados. Os elementos apresentam superfícies de contato direcionalmente estruturadas. Esta estrutura das superfícies de contato dá origem aos elementos de uma coluna que demonstra uma maior resistência ao afrouxamento após o atarraxamento intensivo à máquina ou o atarraxamento aplicado manualmente, o que é, portanto, freq³entemente inadequado, por meio do que um nível mais alto de confiabilidade operacional é alcançado, em particular, no caso das colunas de eletrodos que são atarraxadas manualmente entre si.
