Manganese-copper alloy ultra-thin strip processing method

The invention relates to a processing method of a manganese-copper alloy ultra-thin strip, which adopts a heat treatment process and a rolling process to respectively control grains of a manganese-copper alloy strip structure before final rolling, especially the size and the number of twin crystals, and the plate shape of the ultra-thin strip in the final rolling process. The problem that in the prior art, the surface orange-peel-shaped plate shape is poor in the machining process of the ultra-thin precise manganese-copper alloy strip is solved. 本发明涉及一种锰铜合金极薄带材加工方法，该方法采用热处理工艺和轧制工艺分别控制最后轧制前锰铜合金带材组织的晶粒，尤其是孪晶的尺寸和数量，和最后轧制过程中极薄带材板形，解决现有技术中极薄精密锰铜合金带材加工过程中的表面橘皮状板形不良缺陷问题。
