High-precision high-performance molybdenum belt and preparation method thereof

The invention provides a high-precision high-performance molybdenum belt and a preparation method thereof. The molybdenum belt is rolled through the precision rolling mill with tension, the high-precision molybdenum belt is obtained by controlling parameters such as the tension and the roll gap value, and meanwhile the prepared molybdenum belt has high performance by adjusting the rolling technology. The precision and the performance of the molybdenum strip prepared through the method are greatly improved, and the high-precision and high-performance molybdenum strip with the thickness being 0.1-0.3 mm, the thickness tolerance being +/-0.01 mm, the rolling tensile strength being larger than or equal to 750 MPa, the rolling elongation being larger than or equal to 10%, the transverse tensile strength being larger than or equal to 750 MPa, the transverse elongation being larger than or equal to 1%, the hardness value being smaller than or equal to 250 HV and the cup drawing value being larger than or equal to 4
