High-accuracy high-moulding brass strip and processing technology thereof

Abstract

The invention discloses a high-accuracy high-moulding brass strip and a processing technology thereof. The brass strip processing technology comprises the following steps of P1, performing smelting; P2, performing casting; P3, performing primary rolling; P4,performing intermediate annealing; P5, performing finish rolling in advance; P6, performing rough shearing; P7, performing pickling; P8, performing finish rolling; and P9, performing postprocessing: cutting plates after finish rolling into required width and length, and after the qualified state is achieved through checking and measuring, performing packaging and warehousing so as to complete processing of brass strips. According to the high-accuracy high-moulding brass strip and the processing technology thereof provided by the invention, a manner of repeatedly smelting and batch melting is adopted, and in the process, protection treatment and degassing treatment are performed, so that the mixing degree of alloys can be effectivelyincreased, and the texture uniformity and structural performance of the brass strip are guaranteed; and besides, through repeated rolling and preprocessing, the internal performances and the surfaceperformances are effectively improved, the technology flow is easy to control, production and processing are convenient, and popularization and usage are facilitated.

Description

technical field [0001] The invention relates to the technical field of brass strips, in particular to a high-precision and high-shape brass strip and its processing technology. Background technique [0002] Brass strips have stable mechanical properties and wear resistance, and can be used to manufacture precision instruments, ship parts, bullet casings, etc., and have good plasticity, so they can also be used to manufacture plates, pipes and deep-drawn parts. [0003] However, when the existing brass strips are processed, the mixing uniformity of the alloy cannot be guaranteed, resulting in poor texture uniformity of the brass strips, which in turn affects its structural strength and local performance, resulting in poor stability of the brass strips in use, and now Some processing processes are not easy to control and operate, which affects processing efficiency and is not conducive to use. A new processing method needs to be proposed. Contents of the invention [0004] ...
