Abstract

The invention belongs to the field of non-ferrous metal processing, particularly discloses a method for preparing a C70250 nickel-silicon bronze strip by using a horizontal continuous casting blank, and provides the following scheme: the C70250 nickel-silicon bronze strip comprises the following raw materials in parts by weight: 95 to 105 parts of copper, 0.3 to 0.9 parts of chromium carbide, 3 to 4 parts of fluorine, 0.10 to 0.15 part of nickel, 0.01 to 0.15 part of silicon, 0.4 to 0.9 part of calcium, 2 to 3 parts of boron, 0.2 to 0.4 parts of chromium, 0.01 to 0.10 parts of zirconium and 0.01 to 1.00 part of rare earth; and hot working is conducted, specifically, a horizontal slab continuous casting machine is prepared, hot working is conducted on the cast ingot at the temperature of 700-980 DEG C, the cast ingot is placed in the horizontal slab continuous casting machine, and the reduction of the cross section area of hot working of the cast ingot is controlled to be not lower than 75%. The minimization of the yield strength anisotropy of the present invention results in an extended and stable service life of a workpiece processed from the C70250 nickel silicon bronze strip.

Description

technical field [0001] The invention relates to the technical field of non-ferrous metal processing, in particular to a method for preparing a C70250 nickel-silicon bronze strip by using a horizontal continuous casting slab. Background technique [0002] In recent years, with the development of the electronics industry, various electronic devices have developed towards miniaturization, thinning and light weight, and the weight reduction and high integration of the devices used in them have promoted the miniaturization, light weight and high performance of electronic components . At the same time, higher requirements are put forward for the performance of structural parts, requiring the materials used in the preparation of parts to meet performance requirements such as strength, conductivity, and bending. More importantly, with the miniaturization and concentration of electronic components, the accompanying The problem of fever cannot be ignored. [0003] Nickel-silicon bro...
