Problems solved by technology

[0003] However, when the existing brass strip is prepared, and the material ratio is different, it will not only affect its internal structural characteristics, but also affect the surface processing, and the existing preparation method cannot guarantee the fineness of each raw material, resulting in large particle crystals. , reduces its plasticity, and is also not conducive to improving the surface properties through subsequent processing, low precision, and is not conducive to use. A preparation method for zinc needs to be proposed

Abstract

The invention discloses a formula for a high-accuracy brass strip and a preparation method thereof. The brass strip is prepared from the following components in percentage by weight: 65 to 73 percentof copper, 2.5 to 4.5 percent of tin, 1 to 1.5 percent of nickel, 1.5 to 3.5 percent of boron, 0.5 to 0.8 percent of zinc, and the balance of inevitable impurities. According to the formula for the high-accuracy brass strip and the preparation method thereof provided by the invention, gassing and vibration treatment is performed on flowing water in a casting stage, so that the crystal refining degree can be ensured; the casing quality is enhanced; and subsequence machining is facilitated. In a rolling stage, repeated rolling and milling operations are performed, so that the surface quality canbe improved effectively; the internal precision and surface precision of the brass strip are ensured; preparation and production are facilitated; and convenience is brought to popularization and use.

Description

technical field [0001] The invention relates to the technical field of brass strips, in particular to a formula of high-precision brass strips and a preparation method thereof. Background technique [0002] In the current industrial production, brass strip is widely used as an intermediate raw material, and its precision and structural characteristics are directly related to the production quality of subsequent products. [0003] However, when the existing brass strip is prepared, and the material ratio is different, it will not only affect its internal structural characteristics, but also affect the surface processing, and the existing preparation method cannot guarantee the fineness of each raw material, resulting in large particle crystals. , reducing its plasticity, and it is also not conducive to improving the surface properties through subsequent processing, and the precision is low, which is not conducive to use. A preparation method for zinc needs to be proposed. C...
