Xav txog cov hlau tsis tu ncua raws li koj cov khoom siv niaj hnub, tab sis cov hlau tshwj xeeb? Qhov ntawd zoo li cov khoom muaj zog heev uas lawv siv hauv cov foob pob hluav taws, ua tau zoo nrog qee cov kauj ruam zoo nkauj. Cov hlau ib txwm tsis tuaj yeem txiav nws rau cov haujlwm tseem ceeb, yog li cov txheej txheem steel tshwj xeeb hauv kev txuag hnub.
1. Cov hlau tshwj xeeb yog dab tsi?
Cov hlau tshwj xeeb tsis yog ib qho xwb; nws zoo li lub siab - kawg ntawm cov hlau. Nws pib nrog cov hlau tsis tu ncua, tab sis cov tshuaj sib xyaw yog tweaked tsuas yog txoj cai, thiab cov kev tsim tshwj xeeb yog siv los muab nws lub peev xwm uas ib txwm hlau tsis tuaj yeem sib tw. Nov yog qhov ua rau nws tshwj xeeb:
- Cov khoom xyaw: Nws zoo li ib daim ntawv qhia meej. Xav txog hlau thiab carbon, ntxiv rau cov khoom xws li chromium, nickel, thiab lwm yam. Muab pov rau hauv chromium thiab npib tsib xee ua rau nws tsis tshua muaj xeb. Ntxiv tungsten thiab vanadium, thiab nws tau txais txoj kev nruj dua tiv thaiv kev hnav thiab tsim kua muag, ntxiv rau nws tseem nyuaj txawm tias nws kub. Tau txais tus nqi ntawm txhua lub ntsiab lus yog qhov tseem ceeb heev kom tau txais cov txiaj ntsig koj xav tau.
- Yuav Ua Li Cas: Nws tsis yog hais txog melting thiab shaping. Ua cov hlau tshwj xeeb txhais tau hais tias ua cov khoom tsis zoo xws li lub tshuab nqus tsev degassing, electroslag remelting, thiab ceev faj forging thiab kho cua sov. Electroslag remelting yeej txiav cov khib nyiab thiab qhov tsis zoo hauv cov hlau thiab ua rau nws cov qauv zoo thiab txawm.
Kev ua haujlwm tshwj xeeb: yug rau qhov xwm txheej hnyav. Cov tswv cuab ntawm tsev neeg no muaj lawv tus kheej cov txuj ci tshwj xeeb, uas tuaj yeem faib ua feem ntau:
- Hom tawv: nws muaj zog thiab tsis yooj yim tawg thaum nws dais siab thiab cuam tshuam.
- Thaum tshav kub kub-resistant/cold-resistant: qhov kev ua tau zoo yog tseem ruaj khov nyob rau hauv ultra- kub boiler los yog polar tsawg kub ib puag ncig.
- Anti- hom corrosion: nws tuaj yeem tiv taus qhov corrosion ntawm ib puag ncig hnyav xws li kua qaub, alkali thiab dej hiav txwv ntev.
- Lub cev tshwj xeeb: nrog rau cov hlau nplaum tshwj xeeb thiab nthuav coefficient.
2. Vim li cas cov phiaj xwm kev lag luam tsis sib cais los ntawm cov hlau tshwj xeeb?
Cov hlau tshwj xeeb yog lub hauv paus ntawm kev txhawb nqa kev lag luam niaj hnub kom txav mus rau siab - kawg thiab qhov kawg, thiab nws qhov kev hloov tsis tau raug cuam tshuam los ntawm qhov tseem ceeb hauv qab no:
(1) Kev nyab xeeb thiab muaj peev xwm nyob ntawm tej yam tseem ceeb heev
Thaum cov khoom tawg, nws tuaj yeem ua phem heev, xws li:
- Hauv lub zog: Nuclear nroj tsuag xav tau cov hlau tshwj xeeb uas tuaj yeem sawv ntsug rau hluav taws xob thiab vwm cua sov thiab siab. Tsis tas li ntawd, cov chaw tsim hluav taws xob xav tau cov hlau uas tuaj yeem ua kom sov tshaj 600℃rau lub sijhawm ntev.
- Rau kev thauj mus los: High- tsheb ciav hlau ceev ua rau muaj kev ntxhov siab ntau rau cov axles thiab bearings. Lawv xav tau super- hlau ntshiab uas yuav tsis tawg yooj yim. Txawm ib qho teeb meem me me tuaj yeem ua rau muaj kev puas tsuaj loj.
- Hauv chemistry: Tanks thiab kav dej feem ntau kov cov khoom uas tuaj yeem noj tau ntawm lawv. Tias yog vim li cas lawv xav tau super stainless hlau lossis npib tsib xee alloy kom tsis txhob xau thiab muaj kuab paug.
(2) Kev ua haujlwm Leap
Cov hlau tshwj xeeb pab cov cuab yeej ntaus cov kev ua tau zoo tshiab.
- Aerospace: Lub dav hlau tsaws iav xav tau cov hlau muaj zog heev uas tseem tawv heev. Qhov kev sib tw toughness no yog qhov tseem ceeb los tuav lub zog loj thaum lub sij hawm tawm mus thiab tsaws. Cav hniav siv superalloys uas muaj zog txawm tias thaum tej yam kub.
- Sab saum toj-Kev Tsim Kho: Cov cuab yeej siv tshuab Precision siv cov hlau tshwj xeeb rau lawv cov spindles thiab cov lus qhia. Cov hlau no hnav- tiv taus thiab nyob twj ywm tib lub sijhawm, uas ua rau lub tshuab raug rau ntau xyoo. Tuag steel lub hardness, hnav tsis kam, thiab toughness txiav txim siab ntev npaum li cas stamping tuag thiab cov khoom zoo npaum li cas.
(3) Loj Economic Perks
Cov hlau tshwj xeeb yuav raug nqi ntau dua, tab sis nws them nyiaj loj hauv lub sijhawm ntev:
- Siv sijhawm ntev dua, raug nqi tsawg dua: Ib qho saum toj kawg nkaus -notch tuag steel stamping khoom tuaj yeem kav 5-10 npaug ntev dua li ib txwm. Qhov no txo qis ntawm kev hloov pauv, ncua sijhawm, thiab tag nrho cov nqi.
- Cov khoom sib zog, kev ua tau zoo dua: Siv cov hlau muaj zog, lub teeb tshwj xeeb hauv tsheb thiab dav hlau ua rau lawv sib zog thiab nyab xeeb dua. Qhov no txhais tau tias lawv hlawv roj tsawg lossis lub zog, pab ib puag ncig.
- Kev saib xyuas tsawg dua: Cov hlau tshwj xeeb uas tiv thaiv xeb txo qis npaum li cas cov khoom xav tau kho, uas txuag thiab ua kom cov khoom ua haujlwm zoo hauv kev lag luam xws li tshuaj lom neeg thiab kev lag luam sab nrauv.
3. Cov lus xaus
Cov hlau tshwj xeeb yuav tsis yog ib yam uas koj pom txhua hnub, tab sis nws zoo li cov pob txha zais lossis lub khoos phis tawj tseem ceeb hauv ntiaj teb kev lag luam. Nws ntsiag to qhia tias muaj zog npaum li cas, meej, thiab qib siab ntawm lub teb chaws kev lag luam. Cov hlau tshwj xeeb ua tau zoo npaum li cas teeb tsa qhov kev txwv rau txhua yam - xav tob -sea probes, spacecraft, fais fab nroj tsuag, thiab siab - tsheb ciav hlau ceev. Tias yog vim li cas lub teb chaws muaj kev lag luam sab saum toj ib txwm sim los nrog tshiab thiab zoo dua tshwj xeeb steel tech. Nws yog thaj chaw tseem ceeb uas lawv sib tw.
