摘要： PROBLEM TO BE SOLVED: To provide a method of deciding line speed of a continuous pickling line of a steel strip by which a threading speed at which descaling is possible is quickly calculated when passing the steel strip at the line speed which does not exceed the threading speed at which the descaling is possible through a plurality of descaling equipment.
SOLUTION: Actual descaling conditions of the steel strip is obtained from each descaling equipment by using a process computer and, next, speed lowering allowance is determined for every descaling equipment by taking the obtained actual descaling conditions and the target descaling conditions in a plurality of descaling equipment into consideration. The threading speed at which descaling is possible of the steel strip is calculated on the basis of the integrated value of the speed lowering allowance obtained by integrating the allowance.
