Abstract

processo para a produção de tubos de aço de precisão produzidos a frio. a presente invenção refere-se a um processo para a produção de tubos de aço de precisão produzidos a frio, especialmente estirados a frio, para a aplicação especialmente como tubos cilíndricos submetidos à pressão, com adição opcional de um ou mais elementos de liga, bem como impurezas devido à fundição. nesse caso, um tubo preliminar soldado sem costuras produzido a quente ou produzido a partir de uma faixa de laminação, com estado inicial definido, é estirado em uma etapa ou em várias etapas para formar um tubo final, e o tubo é submetido a um tratamento de beneficiamento antes da etapa final.process for the production of cold-rolled precision steel tubes. The present invention relates to a process for the production of cold-rolled, specially cold-drawn, precision steel pipes, for the application especially as pressurized cylindrical pipes, with optional addition of one or more alloying elements as well as as impurities due to foundry. In this case, a seamless welded preliminary pipe produced from a hot rolled strip or produced from a rolling strip with a defined starting state is drawn in one or several steps to form a final pipe, and the pipe is subjected to a treatment. of beneficiation before the final stage.
