High-performance phosphor bronze belt and preparing method thereof

Abstract

The invention relates to a high-performance phosphor bronze belt. The high-performance phosphor bronze belt comprises following chemical components including, by weight percent, 10.0%-13.0% of Sn, 0.1%-0.65% of Zn, 0.05%-0.5% of Ni, 0.1%-0.5% of Fe, 0.01%-0.5% of P, 0.001%-0.02% of RE, 0.005%-0.05% of B and the balance Cu. A technology method for preparing the high-performance phosphor bronze beltcomprises the following steps that a, burdening, charging, smelting and casting are conducted according to the mass percent; b, pre-blooming is conducted; c, homogenizing annealing is conducted; d, face milling is conducted; e, rough milling is conducted; f, intermediate annealing is conducted; g, acid pickling is conducted; h, intermediate rolling is conducted; i, continuous annealing is conducted; j, fine rolling is conducted; k, acid pickling is conducted; m, stretch bending straightening is conducted; n, low-temperature annealing is conducted; o, shearing is conducted; and p, packaging and warehousing are conducted.
