Description
Technical field
The present invention relates to a kind of automatic deviation correction compound precision resistance band, belong to new material technology field.
Background technology
Cu-Mn-Ni system precision electrical resistance alloy is that high-precision electric apparatus prepares critical material, extensively applies intelligent electric meter, electricity
Son and electrical measuring instrument manufacture field, such as the diverter etc. in intelligent electric meter.This alloy requires minimum resistance temperature drift coefficient
(i.e. the resistance rate of change to temperature) and to copper thermoelectrical potential, and good corrosion resistance and welding technological properties.At present, Cu-Mn-Ni
Being that precision resistance material mainly includes 6J8,6J12 and 6J13 alloy, its chemical composition is shown in Table 1.Mn is that precision electrical resistance alloy is main
Alloying element, the interpolation of Mn element may result in raising and the reduction of temperature drift coefficient of resistance alloys rate.Mn is element alloyed most preferably
Composition range is 11～13wt%, and now copper-manganese temperature drift coefficient is less.The addition of Ni element is primarily to reduce Cu-Mn-Ni
The alloy thermoelectrical potential to fine copper, improves manganin antioxidation, corrosion resistance ability simultaneously, and material resistance is affected relatively by composition fluctuation
Little.
Intelligent electric meter diverter groundwork interval is 20～100 DEG C, and the dynamic electric of existing single precision electrical resistance alloy
Resistance still suffers from larger fluctuation in this temperature range, result in suitable error in dipping.
Table 1 Cu-Mn-Ni system's precision electrical resistance alloy chemical composition (wt%)
Summary of the invention
It is an object of the invention to provide a kind of combined precision electric resistance alloy band, to overcome 20～100 DEG C of temperature ranges
In, the dynamic electric resistor of existing electric resistance alloy is larger fluctuation in this temperature range, the problem causing error in dipping.
For achieving the above object, the solution of the present invention is:
A kind of combined precision electric resistance alloy band, it is spliced by band A is parallel with band B, wherein band A chemistry one-tenth
Being divided into: Mn constituent content is 7.2～7.8wt%, Si constituent content is 2.1～2.5wt%, Cu surplus；Band B chemical composition
For: Mn constituent content is 7.2～7.8wt%, and Ni constituent content is 1.5～1.8wt%, Cu surplus.
Described band A and band B is to use high-power electron beam weldering mode is parallel is spliced into composite strip precision electrical resistance alloy
Band.
Described band A is parallel with band B is spliced into composite strip, is then carried out by the composite strip spliced employing finish draw
Outward appearance finishing, finally carries out vacuum seamless annealing and forms combined precision electric resistance alloy band.
After using such scheme, the present invention is existed by the resistivity using the band A and band B of heterogeneity metal material
There is in temperature range 20～100 DEG C the dull contrary variation tendency of approximately linear, by the parallel welding of bi-material, sliceable
Become a kind of compound precision resistance band, it is achieved band A and band B tandem working in diverter so that splicing tape resistance is total
On body, temperature drift is in the trend of cancelling out each other, so that shunting utensil has higher sampling precision in operating temperature range,
The measuring accuracy of intelligent electric meter is finally greatly improved.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
Present invention is disclosed a kind of combined precision electric resistance alloy band, it is spliced by band A is parallel with band B, its
Middle band A chemical composition is: Mn constituent content is 7.2～7.8wt%, and Si constituent content is 2.1～2.5wt%, Cu surplus；Band
Material B chemical composition is: Mn constituent content is 7.2～7.8wt%, and Ni constituent content is 1.5～1.8wt%, Cu surplus.
This band A and band B is to use high-power electron beam weldering mode is parallel is spliced into composite strip, then will splice
Composite strip uses finish draw to carry out outward appearance and obtains finishing, finally carries out vacuum seamless annealing and forms combined precision electric resistance alloy band.
Know-why: the resistance value of high concentration solid solution with the relation of temperature is:(wherein ρ M
For matrix material resistivity, ρ s is solvent element resistivity, and T is temperature).Materials A and material B (being shown in Table 2) are due to chemical composition
Difference, cause its temperature drift in 20～120 DEG C of temperature ranges to have contrary trend, by both alloy strip steel rolled stocks according to
The size of its temperature drift coefficient carries out series connection splicing by different width ratio, can get overall temperature in 20～120 DEG C of temperature ranges
Float the diverter that coefficient is close to zero.
Table 2
| Mn/wt.% | Ni/wt.% | Si/wt.% | Temperature drift factor alpha/ | |
| Band A | 7.2～7.8 | -- | 2.2～2.5 | -25 |
| Band B | 7.2～7.8 | 1.5～1.8 | -- | 24.6 |
The band A of the present invention has dull contrary change in temperature range 20～100 DEG C and becomes with the resistivity of band B
Gesture, owing to the copper-manganese sheet in diverter is that vertical bandlet length direction intercepts rectangular particles, electric current is through copper-manganese sheet, band A
It is series combination with band B, therefore both positive and negative temperature drift can be cancelled out each other, so that shunting utensil is in operating temperature range
Inside there is higher sampling precision, be finally greatly improved the measuring accuracy of intelligent electric meter, the i.e. present invention will have positive temperature drift and
Two kinds of precision electrical resistance alloys of subzero temperature drift carry out series connection splicing in proportion so that it is float positive and negative supporting 20～120 DEG C of temperature range temperature
Disappear, thus there is minimum resistance temperature drift.Compared with other traditional single alloy strip steel rolled stock, the product involved by this technological invention
It is more stable that product have resistance in using temperature range, the higher advantage of precision.
