    • In a method of continuously annealing and pickling steel strips successively transferred through a continuous annealing apparatus including heating and cooling zones and a pickling apparatus, annealing the steel strips is effected in reducing atmosphere and thereafter pickling is effected at least by nitric acid electrolytic treatment. In an apparatus for continuously annealing and pickling steel strips, including a continuous annealing furnace and a pickling apparatus, the continuous annealing furnace consists of vertical furnaces capable of advancing a steel strip in a manner substantially repeating upward and downward movements alternately in substantially vertical directions and the pickling apparatus comprises at least a nitric acid electrolytic cell. In another aspect, continuous annealing furnace consists of one pass furnace capable of advancing the steel strip only once and forming a high temperature heating zone and a high temperature cooling zone of the annealing furnace, and vertical furnaces respectively forming a lower temperature heating zone and a low temperature cooling zone and capable of advancing a steel strip in a manner substantially repeating upward and downward movements alternately in substantially vertical directions. The one pass furnace is horizontal or vertical.
    • 在通过包括加热和冷却区的连续退火设备和酸洗设备连续退火和酸洗钢带的方法中,在还原气氛中进行钢带的退火,此后至少通过硝酸电解处理进行酸洗。 在连续退火炉和酸洗设备中连续退火和酸洗钢带的设备中,连续退火炉由垂直炉组成,其能够以基本上在大致垂直方向上交替地基本重复上下运动的方式推进钢带;以及 酸洗装置至少包括硝酸电解池。 另一方面,连续退火炉由能够使钢带前进一次并形成退火炉的高温加热区和高温冷却区的单通道炉,以及分别形成较低温度加热区和 低温冷却区域,能够以基本上在大致垂直方向交替地大致重复上下运动的方式推进钢带。 单程炉是水平或垂直的。
