Xaiv cov khoom sib txawv ntawm cov hluav taws xob cua sov ntawm cov xov hlau raws li lub hom phiaj sib txawv
Raws li paub zoo, qhov tseem ceeb tshaj plaws thaum yuav khoom yog nws cov nqi-zoo. Qhov pheej yig dua nws yog, qhov zoo dua. Qhov kim dua nws yog qhov tsim nyog. Thaum xaiv cov khoom, nws yog ib qho tseem ceeb uas yuav tsum tau soj ntsuam nws cov nqi-zoo thiab xyuas kom meej tias tus nqi tsim nyog thiab qhov zoo tshaj plaws. Peb tuaj yeem nrhiav tau cov khoom tsim nyog rau cov khoom siv hluav taws xob hluav taws xob, thiab nws cov nqi zoo li cas?
Raws li cov ntaub ntawv yav dhau los thiab kev sib txuas lus ntawm cov neeg yuav khoom thiab cov chaw tsim khoom, ob peb txoj hauv kev xaiv cov khoom siv hluav taws xob cua sov nrog cov nqi siab dua tau muab sau tseg, rau kev siv ntawm cov neeg yuav khoom nkaus xwb:
1. Cov neeg uas paub txog cov hluav taws xob cua sov xov hlau paub tias cov hluav taws xob cua sov xov hlau feem ntau muab faib ua ob ntu: hlau chromium aluminium series thiab nickel chromium series.
Hauv cov hlau chromium aluminium series, nws tau muab faib ua {{0}}cr25AL5, 0cr21Al6Nb, thiab 0Cr27Al7Mo2.
Cov nickel chromium series tau muab faib ua Cr20Ni80, Cr15Ni60, Cr20Ni35, thiab Cr25Ni20.
2. Xaiv cov hom hluav taws xob sib txawv ntawm cov hluav taws xob cua sov raws li lub hom phiaj sib txawv.
(1) Tus neeg yuav khoom yog lub Hoobkas khoom siv tshuab, lub tshuab ntim khoom, lub tshuab sealing, lub tshuab ntim khoom, thiab lwm cov chaw tsim khoom uas tsis xav tau qhov kub thiab txias li ntawm 200-300 degrees Celsius. Nws raug nquahu kom siv 0cr20Ni80 series nickel chromium hlau. Cov nickel chromium hlau muaj qhov zoo weldability, yog mos, thiab tsis yooj yim rau embrittle, thiab nws yog qhov zoo tshaj plaws los siv cov hlua khi vim tias lub zog thauj khoom ib square meter ntawm cov hlua khi yog loj dua li ntawm cov xov hlau, qhov dav yog siab dua, thiab tus nqi poob yog me dua li ntawm cov xov hlau.
(2) Rau cov chaw tsim hluav taws xob, cov chaw tsim hluav taws xob, thiab lwm yam, tus neeg yuav khoom yuav tsum xav txog qhov teeb meem ntawm qhov kub thiab txias. 100-900 degrees Celsius tsis xav tau qhov zoo tshaj plaws. Nws raug nquahu kom siv cov hlau ntau tshaj plaws chromium aluminium 0cr25al5, uas yog pheej yig thiab tuaj yeem siv rau qhov kub siab tshaj ntawm 900 degrees Celsius. Yog hais tias qhov saum npoo ntawm cov hluav taws xob cua sov xaim yog cov cua sov kho, acid whitened lossis annealed los txhim kho nws cov oxidation tsis kam, nws yog qhov zoo dua thiab siv tau zoo. Yog tias lub qhov cub nyob nruab nrab ntawm 900 thiab 1000 degrees Celsius, nws raug nquahu kom siv 0cr21al6nb. Cov kab hluav taws xob cua sov no muaj qhov kub thiab txias dua thiab zoo dua vim qhov sib ntxiv ntawm Nb lub caij. Yog tias qhov cub kub kub ntawm 1100 thiab 1200 degrees Celsius, nws raug nquahu kom siv Ocr27al7mo2, uas muaj MO cov xov hlau puag ncig thiab muaj qhov kub siab dua. Txawm li cas los xij, qhov siab dua qhov purity ntawm 0Cr27al7MO2, cov hlau muaj zog dua, qhov zoo dua cov oxidation tsis kam, tab sis qhov nkig ntau dua. Yog li ntawd, nws raug pom zoo los tuav nws maj mam thiab muaj lub Hoobkas cua nws mus rau qhov tsim nyog loj, Tsuas yog rov qab mus thiab muaj teeb tsa rau tus neeg yuav khoom lawv tus kheej. Kuj tseem muaj qee qhov cub hluav taws kub kub, uas yuav tsum tau 1400 degrees. Nws raug nquahu kom siv HRE los ntawm Shougang, sedesMBO los ntawm Tebchaws Meskas, lossis Kanthal APM los ntawm Sweden (Yancheng Songtai yog tus neeg muag khoom ntawm Kanthal los ntawm Sweden). Tau kawg, cov nqi kuj tau nce siab thiab siab dua. Nyob rau hauv cheeb tsam Jiangsu, Yancheng Songtai cov hluav taws xob cua sov xov hlau yog qhov zoo tshaj plaws manufacturers.
(3) Ceramic factories, iav factories. Nws raug nquahu kom siv HRE ncaj qha lossis cov xaim hluav taws xob xa hluav taws xob xaim hluav taws xob, vim tias cov hluav taws xob hluav taws xob kub kub tuaj yeem ua rau muaj kev vibration. Lub sij hawm ntev hluav taws xob kev co tuaj yeem ua rau tsis zoo hluav taws xob cua sov xov hlau poob thiab ua rau muaj kuab paug. Tsuas yog los ntawm kev xaiv cov khoom siv hluav taws xob zoo hluav taws xob tuaj yeem ua tiav cov txiaj ntsig zoo.
