Manufacturing process for copper-nickel compensating conductor alloy wire

Abstract

The invention discloses a manufacturing process for a copper-nickel compensating conductor alloy wire, and relates to the technical field of alloy wire processing. The manufacturing process includes the steps of main material selection, ingot casting refining, forging and hot rolling, cold wire drawing, heat treatment, finished product inspection and storage. The manufacturing process has the beneficial effects that the method that reasonable processing equipment is supplemented by corresponding process parameter selection for processing and preparing the copper-nickel alloy wire is determined, the measureable temperature interval of the prepared copper-nickel alloy wire is 0-100 DEG C, a nickel-chromium or nickel-silicon alloy wire on the market can be effectively replaced, manufacturing cost is low, measuring is accurate, stability performance is high, the problem that the alloy wire is high in manufacturing cost in the prior art is effectively solved, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of alloy wire processing, in particular to a manufacturing process of copper-nickel compensation wire alloy wire. Background technique [0002] Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It directly measures temperature, and converts the temperature signal into thermal electromotive force signal, and converts it into the temperature of the measured medium through electrical instruments. The shape of various thermocouples is often very different due to needs. They are not the same, but their basic structures are roughly the same. They are usually composed of main parts such as galvanic wires and junction boxes. They are usually used in conjunction with display instruments, recording instruments, and electronic regulators. Thermocouples are mainly used for liquids, steam, and gases. For the measurement of the temperature of the medium and the surface tem...

[0002] Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It directly measures temperature, and converts the temperature signal into thermal electromotive force signal, and converts it into the temperature of the measured medium through electrical instruments. The shape of various thermocouples is often very different due to needs. They are not the same, but their basic structures are roughly the same. They are usually composed of main parts such as galvanic wires and junction boxes. They are usually used in conjunction with display instruments, recording instruments, and electronic regulators. Thermocouples are mainly used for liquids, steam, and gases. For the measurement of the temperature of the medium and the surface temperature of the solid, in the actual application of the thermocouple, the alloy wire is generally treated with nickel-chromium or nickel-silicon, but when the nickel-chromium or nickel-silicon is processed and prepared, due to its actual material The high cost directly leads to the high actual cost of the alloy wire, and in actual use, nickel-chromium or nickel-silicon can adapt to the use of ultra-high temperature. In general low temperature, the use of nickel-chromium or nickel-silicon alloy wire is undoubtedly Overkill for underutilization. At present, there is no use of other materials in the market to replace expensive nickel-chromium or nickel-silicon alloy wires. Therefore, this technical point is a technical difficulty that needs to be overcome at this stage.
