Nickel-chromium cov ntaub ntawv yog dav siv nyob rau hauv industrial hluav taws xob furnaces, khoom siv hauv tsev, far-infrared pab kiag li lawm thiab lwm yam khoom siv vim lawv zoo kub kub lub zog thiab muaj zog plasticity. Nickel-chromium thiab hlau, txhuas, silicon, carbon, sulfur thiab lwm yam khoom tuaj yeem ua rau nickel-chromium alloy hlau, uas muaj kev tiv thaiv siab thiab kub tsis kam thiab yog cov khoom siv hluav taws xob cua sov ntawm lub tshuab hluav taws xob, hluav taws xob soldering hlau, hluav taws xob hlau thiab lwm yam khoom.
Tsis tas li ntawd, NiCr hlau feem ntau yog siv nyob rau hauv lub kauj ntawm zawv zawg rheostat los tiv thaiv Circuit Court thiab hloov tam sim no hauv Circuit Court los ntawm kev hloov qhov tsis kam ntawm qhov nkag mus rau hauv Circuit Court, yog li hloov qhov hluav taws xob hla ntawm tus neeg xyuas pib (cov khoom siv hluav taws xob) txuas nrog hauv series nrog. nws, Nws yog dav siv nyob rau hauv ib tug loj tus naj npawb ntawm cov khoom siv hauv tsev.
NiCr Alloy Series
Ni90Cr10 sawb yog hom nickel-chromium alloy cov khoom, nws yog tsim rau kev siv kub txog li 1250 ° C. Chromium cov ntsiab lus muab lub neej zoo heev, nws feem ntau yog siv los ua vape cua sov caij.
Ni90Cr10 yog tus cwj pwm los ntawm kev ua haujlwm siab, zoo oxidation tsis kam, zoo ductility tom qab siv thiab zoo weldability. NiCr Alloy yog cov khoom siv zoo rau kev lag luam cua sov.
