Rau cov hlau tsis kam, lub zog ntawm peb qhov kev tiv thaiv tuaj yeem txiav txim siab raws li qhov tsis kam ntawm cov hlau tsis kam. Qhov ntau dua nws lub zog, muaj ntau tus neeg tsis paub yuav ua li cas xaiv cov hlau tsis muaj zog, thiab tsis muaj kev paub ntau txog cov hlau tsis kam. , Xiaobian yuav piav qhia rau sawv daws.

Resistance wire yog hom cua sov tshaj plaws. Nws txoj haujlwm yog tsim kom muaj cua sov tom qab lub zog thiab hloov hluav taws xob rau hauv cov cua sov. Resistance hlau muaj ntau yam kev siv. Ntau cov khoom siv hluav taws xob siv hluav taws xob feem ntau siv cov xaim hluav taws xob ua hluav taws xob ua cua sov. Yog li ntawd, cov hlau tsis kam yog siv rau hauv kev kho mob, tshuaj, hluav taws xob, hluav taws xob, metallurgical machinery, ceramic iav ua thiab lwm yam lag luam.

1. Lub hauv paus ntsiab lus ua haujlwm ntawm cov hlau tsis kam

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov hlau tsis muaj zog yog tib yam li ntawm lwm cov hlau cua sov, thiab nws yog qhov tshwm sim ntawm hluav taws xob cua sov tom qab hlau energized. Hluav taws xob cua sov txhais tau hais tias tom qab tam sim no dhau los ntawm tus neeg xyuas pib, qhov tam sim no yuav tsim kom muaj qee qhov cua sov thiab raug xa mus los ntawm tus neeg xyuas pib. Cov hlau tsis kam nws tus kheej yog tus neeg xyuas pib hlau, uas yuav tawm cov cua sov thiab muab thermal zog tom qab ua kom muaj zog.

2. Kev faib tawm ntawm cov hlau tsis kam

Cov hom ntawm cov hlau tsis kam yog muab faib raws li cov ntsiab lus ntawm cov khoom siv tshuaj lom neeg thiab cov qauv tsim ntawm cov hlau tsis kam. Muaj cov hlau-chromium-aluminium alloy tsis kam xaim thiab nickel-chromium alloy tsis kam xaim. Raws li cov khoom siv hluav taws xob cua sov, ob hom kab hluav taws xob no muaj cov yam ntxwv sib txawv.

3. cov yam ntxwv ntawm cov hlau tsis kam

Cov hlau tsis muaj zog yog tus cwj pwm los ntawm qhov kub thiab txias tsis kam, cua sov ceev, kev pab lub neej ntev, ruaj khov tsis kam, kev sib txawv ntawm lub zog me me, cov xov zoo sib xws tom qab ncab, thiab ci ntsa iab thiab huv si. Nws yog dav siv nyob rau hauv me me hluav taws xob furnaces, muffle furnaces, cua sov thiab cua txias cov cuab yeej, ntau yam ncu, hluav taws xob cua sov raj thiab khoom siv hauv tsev, thiab lwm yam. Ntau yam uas tsis yog-standard industrial thiab civil furnace tuav tau tsim thiab tsim raws li cov neeg siv xav tau kev pab.

4. qhov zoo thiab qhov tsis zoo ntawm hlau-chromium-aluminium alloy kuj hlau

Cov hlau-chromium-aluminium alloy kuj hlau muaj qhov zoo ntawm kev ua haujlwm kub. Qhov kev sim qhia tau hais tias qhov siab tshaj plaws ua haujlwm kub ntawm cov hlau-chromium-aluminium alloy kuj tuaj yeem ncav cuag 1400 ° C. Cov hlau-chromium-aluminium alloy tsis kam xaim muaj lub neej ntev kev pab cuam, siab tiv taus, siab nto compounding, thiab zoo oxidation kuj.

Qhov tsis zoo ntawm hlau-chromium-aluminium alloy tsis kam xaim yog nws lub zog qis hauv qhov kub thiab txias. Raws li qhov kub thiab txias, lub plasticity ntawm hlau-chromium-aluminium alloy kuj hlau yuav nce, uas txhais tau hais tias cov hlau-chromium-aluminium alloy tsis kam hlau yog feem ntau deformation ntawm qhov kub thiab txias. Thiab nws tsis yooj yim rau kho tom qab deformation.

5.Qhov zoo thiab qhov tsis zoo ntawm nickel-chromium alloy kuj hlau

Qhov zoo ntawm nickel-chromium alloy tsis kam xaim yog lub zog siab nyob rau hauv qhov kub thiab txias ib puag ncig, kev ua haujlwm siab kub mus ntev tsis yooj yim rau deform, thiab nws tsis yooj yim los hloov cov qauv, thiab qhov kub thiab txias plasticity ntawm nickel-chromium alloy tsis kam. hlau yog qhov zoo, thiab kev kho tom qab deformation yog qhov yooj yim. Tsis tas li ntawd, npib tsib xee-chromium alloy kuj hlau muaj siab emissivity, tsis-sib nqus, zoo corrosion kuj thiab ntev kev pab cuam lub neej.

Qhov tsis zoo ntawm nickel-chromium alloy tsis kam xaim yog qhov kev ua haujlwm kub tsis tuaj yeem ncav cuag qib ntawm cov xaim yav dhau los. Kev tsim cov nickel-chromium alloy kuj yuav tsum tau siv cov nickel. Tus nqi ntawm cov hlau no siab dua cov hlau, chromium thiab txhuas. Yog li ntawd, kev tsim cov nqi ntawm nickel-chromium alloy tsis kam xaim yog qhov siab, uas tsis tsim nyog rau kev tswj hwm tus nqi.
