Abstract

a presente invenção se refere a um método para tratar uma tira de aço por meio de um líquido de tratamento em uma estação de tratamento, em que a estação de tratamento compreende pelo menos uma seção de aspersão, uma seção de imersão e um meio de coleta comum para o líquido de tratamento, em que a tira de aço consiste em aço inoxidável e é uma tira de aço contínua orientada substancialmente de modo horizontal, tanto em suas direções longitudinais quanto transversais, em que a tira de aço tem uma superfície de topo e uma superfície de fundo, em que o método compreende transportar a tira de aço continuamente através da estação de tratamento em uma direção de transporte, sendo que a direção de transporte é paralela à direção longitudinal da tira de aço, de modo que, em uma primeira etapa, o líquido de tratamento seja aspergido na superfície de topo da tira de aço e na superfície de fundo da tira de aço enquanto a tira de aço está na seção de aspersão da estação de tratamento, em uma segunda etapa, a tira de aço seja imersa no líquido de tratamento enquanto a tira de aço está na seção de imersão da estação de tratamento, em que, enquanto a tira de aço é tratada, o líquido de tratamento é continuamente bombeado para fora do meio de coleta comum e através tanto da seção de aspersão quanto da seção de imersão da estação de tratamento, em que a aspersão do líquido de tratamento nas superfícies de topo e de fundo da tira de aço é fornecida com uso de bocais de aspersão.The present invention relates to a method of treating a steel strip by means of a treatment liquid in a treatment plant, wherein the treatment plant comprises at least one sprinkler section, one dip section and one collecting means. common for the treatment liquid, wherein the steel strip consists of stainless steel and is a substantially horizontally oriented continuous steel strip in both its longitudinal and transverse directions, wherein the steel strip has a top surface and a bottom surface, wherein the method comprises transporting the steel strip continuously through the treatment station in a transport direction, the transport direction being parallel to the longitudinal direction of the steel strip, so that in a first At this stage, the treatment liquid is sprayed onto the top surface of the steel strip and the bottom surface of the steel strip while the steel strip is in the section. At the second stage, the steel strip is immersed in the treatment liquid while the steel strip is in the immersion section of the treatment station, where, while the steel strip is treated, the liquid is The treatment plant is continuously pumped out of the common collection medium and through both the spray station and the treatment station immersion section, where spray liquid treatment on the top and bottom surfaces of the steel strip is provided. using sprinkler nozzles.
