Embodiment Construction

[0013] Example 1. Select the composition content of the alloy as follows: Ni31.5%, C0.1%, Mn0.3%, Si0.1%, and Fe.

[0014] The above ingredients are melted by vacuum induction, cast into electrode rods after melting, and then remelted into ingots by electroslag, forged into slabs of a certain size at 1100 ° C, hot rolled into plates of a certain thickness at the same temperature, after 1050 After heat treatment at 400°C, the thickness of the finished product is obtained by cold rolling, and finally in a vacuum heat treatment furnace, the temperature is kept at 400°C for 2 hours for final aging treatment before use.

[0015] Example 2. Select the composition content of the alloy as follows: Ni32.0%, C0.15%, Mn0.3%, Si0.1%, and Fe.

[0016] The above components are melted by vacuum induction, cast into electrode rods after melting, and then remelted into ingots by electroslag, forged into slabs of a certain size at 1150°C, hot rolled into plates of a certain thickness at the sam...

Abstract

The invention relates to a highly magnetic induction, linear magnet-temperature compensation alloy with broad temperature regioand its production process. The alloy components in percent are as follows: Ni 31.5-32.5%, Mn<=0.4%, Si<=0.3%, C 0.10-1.50%, surplus Fe. The production process is: first adopting vacuum induction melting then casting to make electrode bar, then electroslag remelting it to cast ingot, heating to 1100-1150 DEG C, hot forging hot-rolled sheet blank, heating to 1050 DEG C-1100 DEG C, hot-rolling to sheet, 1050 DEG C-1100 DEG C heat treatment, acid cleaning, cold rolling and obtaining band of finished product thickness, after processing element, using after final ageing treatment 1-2 hours in vacuum heat treatment furnace under 400 DEG C-500 DEG C. The inventive alloy has a wider usage temperature range, temperature point for testing is more than before, and B-t linearity is well, so the inventive alloy surpass the existing FeNi magnet compensation alloy in usage temperature range and magnet compensation ability.

Description

technical field [0001] The invention belongs to the technical field of magnetic temperature compensation alloy, and relates to a linear magnetic temperature compensation alloy with high magnetic sensitivity and wide temperature range and a production process. Background technique [0002] At present, a relatively complete series of products has been formed in the field of magnetic temperature compensation materials in the world. According to chemical composition, there are five series of magnetic temperature compensation alloys: nickel-copper series, iron-nickel series, iron-nickel-aluminum series, iron-nickel-chromium series and iron-nickel series. Manganese series. China's magnetic temperature compensation alloys mainly include three series of alloys: iron-nickel system, iron-nickel-aluminum system, and iron-nickel-chromium system. The performance of the magnetic temperature compensation alloy is described by the characteristic curve of the magnetic induction intensity ch...
