2. Description of the Related Art A shadow mask incorporated in a color picture tube of a color television or the like is obtained by cutting a shadow mask original plate (a thin steel plate such as a low carbon steel, an aluminum killed steel, or an Fe-Ni alloy) into a required surface size, A flat mask is formed by performing an etching process (formation of fine holes), and then the flat mask is manufactured through a step of stack annealing. This annealing process is performed by stacking a large number (for example, several tens) of flat masks vertically.

A problem in the stack annealing of the flat masks is that a phenomenon (annealing adhesion) that the overlapping surfaces of the flat masks adhere to each other easily occurs. Since the flat mask is a thin plate, if annealing and adhesion occur, not only a troublesome work for peeling is required, but also the plate is bent or wrinkled, which causes a yield loss.

[0004] As a measure to alleviate the adhesion of the annealing, a roughening treatment of the shadow mask original plate (transfer of satin texture by dull roll, etc.) is performed. However, the tendency of the occurrence of annealing adhesion and the difficulty of peeling are as follows. It depends on the grade of the steel sheet to be subjected to stack annealing and the annealing treatment conditions. Therefore, in order to guarantee the quality and production yield of shadow mask products, it is necessary to accurately measure and evaluate the degree of annealing adhesion (easiness of occurrence of annealing adhesion and difficulty of peeling of the adhered surface) of the shadow mask original plate used. Is essential.

The above-mentioned measurement and evaluation of the degree of adhesion of annealing have been performed as a peeling test by an operator manually. However, this method cannot be evaluated under the same conditions due to individual differences in the method of peeling, and it is a sensory evaluation and cannot be quantitatively evaluated. For this reason, it is difficult to provide appropriate feedback to the pre-process necessary for improving annealing adhesion, and there is also a problem in reliability of quality assurance for the user. The present invention has been made in view of the above, and provides a measuring apparatus and a measuring method capable of quantitatively measuring the degree of annealing adhesion of a stack-annealed sheet material and collecting reliable evaluation data.

FIGS. 8A to 8C show examples of the measurement results obtained by the above-mentioned peeling test. The sample steel plates are as follows.

In each of the figures, a shows a change with time of the load (including the steel sheet's own weight) in the peeling process, and b shows the load due to the steel sheet's own weight. The adhesion strength of the superposed surface is obtained as a difference value of “ab”. The reason why the graphs a and b overlap each other in the initial stage of the peeling is that the overlapped surface of the corner (c 1 ) (see FIG. 4) of the sample steel sheet was peeled in advance, and the graph a Change (decrease after increase)
Is due to the fact that the length (l) of the peel boundary (FIG. 4) increases with time (maximum at diagonal c 3 -c 4 ) and then decreases.

The annealing density (the tendency of the occurrence of annealing adhesion / difficulty of peeling) of the graph (a) shows the change over time (curve shape) and the magnitude of the load value (the height of the peak value, the area surrounded by a and b). Is evaluated and determined based on the size of the area. In FIG. 8 [1], since the graph a shows a smooth curve and the peak of the load is an extremely low value, the adhesion of the superposed surfaces is extremely small, and the annealing adhesion is excellent. Can be evaluated. FIG. 2B shows that although the annealing density is more likely to occur than the above [1], the curve shape is smooth and the peeling load has no irregularity and no abrupt change. It is evaluated to be relatively loose. In FIG. 3C, the peak value of the graph a is extremely large, and the curve shape exhibits a remarkably irregular and rapid change. This indicates that the annealing adhesion of the superposed surfaces is remarkable.

However, in the measurement using a steel sheet having a plane size of about 300 × 300 mm as a sample, the displacement ( s) does not substantially affect the measurement and evaluation of the degree of adhesion to annealing.
