Description
The invention belongs to the temperature-measuring element technical field, is a kind of manufacture method of high-accuracy compensating lead wire.
Compensating wire is an indispensable temperature element in the temperature survey, compensating wire has extended pattern and offset-type, extended pattern is the extended line of thermopair, alloy material is identical with thermopair, offset-type adopts the cheap metal manufacturing usually, because alloy composition is different with the alloy composition of thermopair, and cause the pyroelecthc properties of its pyroelecthc properties and thermopair not quite identical, normally used compensating wire can only keep the limit of error of its permission in narrower temperature range, yet, error is very big in actual applications, influences thermometric accuracy greatly.Along with industry and science and technology development, the widespread use of the raising of production technology and automatization level, especially robot calculator, higher to thermometric accuracy requirement, mere formality is offered record, the 19T steel that the Soviet Union produces, liquid steel temperature is in the time of 1630 ℃, and the molten steel rejection rate is lower than 0.1%; Liquid steel temperature is in the time of 1620 ℃-1640 ℃, and the steel scrap rate is increased to 0.2%; Liquid steel temperature is in the time of 1610 ℃-1650 ℃, and the steel scrap rate reaches 0.5%; Measuring accuracy is very big to the influence of 19T steel, and now the standard of the compensating wire of producing all adopts the IEC583-3 of International Electrotechnical Commission, and the standard level franchise is at 0-150 ℃, and ± 2.5 ℃, 0-200 ℃, ± 5 ℃, rethink further raising franchise, be very difficult.Proof is controlled alloy composition by strictness by experiment, and it also is very difficult reaching desirable measurement franchise.
The manufacture method that the purpose of this invention is to provide the high-accuracy compensating lead wire that a kind of manufacture method is simple, cost is low.
The object of the present invention is achieved like this: a kind of manufacture method of high-accuracy compensating lead wire, its process is as follows: the compensating wire alloy silk that goes out corresponding specification by standard production, constantan just is divided into 8 groups by thermoelectrical potential, constantan thermoelectrical potential scope is 4.343-3.995mv, every group of thermoelectrical potential of constantan is spaced apart 0.029mv, nickel-chrome just is divided into 6 groups by thermoelectrical potential, nickel chromium triangle thermoelectrical potential scope is 1.974-2.160mv, every group of thermoelectrical potential is spaced apart 0.029mv, nickel silicon alloy just is divided into 3 groups by thermoelectrical potential, nickel silicon alloy thermoelectrical potential scope is 2.032-1.972mv, and every group of thermoelectrical potential is spaced apart 0.029mv, and the every combination gold after the grouping is by the accuracy class coupling.
