Rau cov hlau tsis kam, lub zog ntawm peb qhov kev tsis kam tuaj yeem txiav txim siab raws li qhov tsis kam ntawm cov hlau tsis kam. Qhov ntau dua nws lub zog, nws muaj peev xwm hais tias ntau tus neeg tsis paub yuav ua li cas xaiv cov hlau tsis kam, thiab tsis muaj ntau yam kev paub txog cov hlau tsis kam. , Xiaobian yuav piav qhia rau txhua tus.

Cov hlau tsis kam yog hom khoom siv cua sov uas siv ntau tshaj plaws. Nws lub luag haujlwm yog tsim cua sov tom qab muaj zog thiab hloov lub zog hluav taws xob mus ua cua sov. Cov hlau tsis kam muaj ntau yam kev siv. Ntau lub cuab yeej cua sov hluav taws xob feem ntau siv cov hlau tsis kam ua khoom siv cua sov. Yog li ntawd, cov hlau tsis kam yog siv rau hauv kev kho mob, tshuaj lom neeg, khoom siv hluav taws xob, hluav taws xob, tshuab hlau, ua cov iav ceramic thiab lwm yam lag luam.

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

Lub hauv paus ntsiab lus ua haujlwm ntawm cov hlau tiv taus yog tib yam li lwm cov khoom siv cua sov hlau, thiab nws yog qhov tshwm sim hluav taws xob cua sov tom qab hlau muaj zog. Kev cua sov hluav taws xob txhais tau tias tom qab tam sim no hla tus neeg xyuas pib, tam sim no yuav tsim qee qhov cua sov thiab raug xa mus los ntawm tus neeg xyuas pib. Cov hlau tiv taus nws tus kheej yog tus hlau tiv taus, uas yuav tso tawm cua sov thiab muab lub zog thermal tom qab raug muaj zog.

2. Kev faib tawm ntawm cov hlau tsis kam

Cov hom hlau tiv taus raug muab faib raws li cov ntsiab lus tshuaj lom neeg thiab cov qauv kev teeb tsa ntawm cov hlau tiv taus. Muaj cov hlau tiv taus hlau-chromium-aluminium alloy thiab cov hlau tiv taus nickel-chromium alloy. Raws li cov khoom siv cua sov hluav taws xob, ob hom hlau tiv taus no muaj cov yam ntxwv ua haujlwm sib txawv.

3. cov yam ntxwv ntawm cov hlau tsis kam

Cov hlau tsis kam yog tus cwj pwm los ntawm kev ua haujlwm kub siab, cua sov sai, lub neej ntev, kev ua haujlwm ruaj khov, kev hloov pauv hluav taws xob me me, qhov sib npaug ntawm cov xov tom qab ncab, thiab qhov chaw ci thiab huv. Nws yog dav siv rau hauv cov cub hluav taws xob me me, cov cub hluav taws xob muffle, cov khoom siv cua sov thiab cua txias, ntau yam cub, cov raj cua sov hluav taws xob thiab cov khoom siv hauv tsev, thiab lwm yam. Ntau yam khoom siv hluav taws xob tsis zoo thiab cov khoom siv hauv tsev tuaj yeem tsim thiab tsim raws li tus neeg siv xav tau.

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

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

Qhov tsis zoo ntawm cov hlau tsis kam hlau-chromium-aluminium alloy yog nws lub zog qis hauv qhov kub thiab txias. Thaum qhov kub nce ntxiv, qhov plasticity ntawm cov hlau tsis kam hlau-chromium-aluminium alloy yuav nce ntxiv, uas txhais tau tias cov hlau tsis kam hlau-chromium-aluminium alloy yuav yooj yim deformed ntawm qhov kub thiab txias siab. Thiab nws tsis yooj yim kho tom qab deformation.

5. qhov zoo thiab qhov tsis zoo ntawm cov hlau tsis kam nickel-chromium alloy

Qhov zoo ntawm cov hlau nickel-chromium alloy tsis kam yog lub zog siab hauv qhov kub thiab txias, kev ua haujlwm kub ntev tsis yooj yim rau deform, thiab nws tsis yooj yim hloov cov qauv, thiab qhov kub thiab txias ib txwm muaj ntawm cov hlau nickel-chromium alloy tsis kam yog qhov zoo, thiab kev kho tom qab deformation yog qhov yooj yim. Tsis tas li ntawd, cov hlau nickel-chromium alloy tsis kam muaj emissivity siab, tsis muaj hlau nplaum, zoo tiv taus corrosion thiab lub neej ntev.

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