Abstract

resumo patente de invenção: "célula de eletrólise de alumínio com dispositivo e método de compressão". a presente invenção refere-se a células de eletrólise de alumínio que possuem uma queda reduzida de voltagem do catodo e métodos para operar as mesmas. mais particularmente, a presente invenção refere-se a um dispositivo de compressão para aplicação de força a uma extremidade do subconjunto de coletor de corrente para aprimorar o contato, reduzindo desse modo a resistência à junção ao longo da interface entre o bloco de catodo e o subconjunto de coletor de corrente. o dispositivo de compressão é usado em conjunto com os sistemas e métodos da presente invenção.
