In summary, many new alloy materials generally have the characteristics of high hardness, high brittleness, low plasticity and low toughness, are difficult to process at room temperature, and often have obvious size effect, friction effect or temperature effect when the size, shape and characteristics of the alloy materials are greatly different, so that the advantages and the disadvantages obviously coexist, which becomes a bottleneck limiting the application range of the alloy materials.
Most of the high-hardness and brittle alloy materials are limited by the inherent characteristics of internal crystal grains, grain boundaries, slip systems and the like, are limited in size, low in plasticity and poor in elongation, and are generally in a narrow and thin strip shape, so that the alloy material is called as an extremely thin alloy narrow strip or an alloy narrow foil strip.

Although the narrow band is relatively wide, the deformation process is relatively uniform, the metal flow rule is simple, and the problem in the rolling process is not very outstanding, for a precise extremely-thin alloy part, when the width-thickness ratio is larger than a specific critical value, obvious problems of plate thickness (longitudinal thickness difference and transverse thickness difference), plate shape (flatness), surface quality and the like often exist. However, for small or micro rolling mills within 150mm, due to limited space and lack of related instruments or types, the small or micro rolling mills are difficult to configure or install high-precision equipment, have low configuration and poor performance, and have functions which are difficult to meet the index requirements of the ultrathin alloy strip. Even at present, no industrial-grade small miniature thickness gauge, convexity meter, plate shape meter and the like with low price and convenient installation exist, so that the performance of a small miniature rolling mill cannot be fully exerted, and the yield of the ultrathin alloy narrow strip is low and the index is poor.
Based on the problems, the invention aims to design a single-hole piezoelectric type miniature plate shape detector suitable for an ultrathin narrow-band rolling mill within 150mm with a front and back coiling device, and aims to provide high-precision online plate shape closed-loop measurement and control for an ultrathin narrow band of a novel alloy material, improve the uniformity of stress strain, and accurately control the transverse metal flow, the longitudinal elongation and the transverse distribution of the high-hardness brittle alloy material so as to obtain the high-precision ultrathin alloy narrow band meeting the flatness requirement.
