Vim li cas thiaj tuaj yeem xa hluav taws xob cua sov tuaj yeem ruaj khov thiab muaj zog ruaj khov?

Nyob rau hauv tus txheej txheem ntawm kev sib txuas lus nrog cov neeg siv khoom, qee cov neeg siv khoom muaj cov kev xav tau siab rau cov khoom siv hluav taws xob cua sov thiab tsis paub yuav ua li cas xaiv cov hlau kab thiab cov khoom siv. Qee cov neeg siv khoom tsis muaj kev txwv nruj rau daim ntawv thov ntawm cov hluav taws xob cua sov, tab sis tsis paub yuav ua li cas xaiv cov hluav taws xob hluav taws xob hluav taws xob uas tsim nyog rau ib puag ncig thiab cov kev xav tau. Raws li kev paub ntau xyoo, cia kuv txheeb xyuas yuav ua li cas xaiv qhov zoo tshaj plaws hauv tsev hluav taws xob cua sov hlau lossis Swedish Kantell hluav taws xob cua sov hlau:

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 suav nrog Cr20Ni80, Cr15Ni60, Cr20Ni35, thiab Cr25Ni20.

2. Xaiv cov khoom siv hluav taws xob sib txawv raws li lawv cov kev siv sib txawv.

(1) Tus neeg yuav khoom yog lub Hoobkas khoom siv tshuab, ntim tshuab, tshuab sealing, ntim tshuab, thiab lwm cov tuam txhab uas tsis xav tau qhov kub thiab txias li ntawm 200-300 degrees. Nws raug nquahu kom siv 0cr20Ni80 series nickel chromium hlau. Nickel chromium hlau muaj qhov zoo weldability, yog mos, thiab tsis yooj yim nkig, thiab nws yog qhov zoo tshaj plaws los siv cov ntaub ntawv tiaj tus vim tias lub zog thauj khoom ib square meter ntawm daim kab xev tiaj tus loj dua li ntawm cov kab hlau, qhov dav yog siab dua, thiab qhov poob qis. yog me dua ntawm cov kab hlau.

(2) Rau cov chaw tsim hluav taws xob hluav taws xob, cov chaw tsim hluav taws xob, thiab lwm yam, cov neeg yuav khoom yuav tsum xav txog qhov kub thiab txias nce, 100-900 degrees, thiab tsis tas yuav tsum muaj qhov zoo tshaj. Nws raug nquahu kom siv cov hlau ntau tshaj plaws chromium aluminium 0cr25al5, uas pheej yig thiab tuaj yeem siv rau qhov kub siab tshaj ntawm 900 degrees. 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 900-1000 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 nyob nruab nrab ntawm 1100-1200 degrees Celsius, nws raug nquahu kom siv Ocr27al7mo2, uas muaj MO puag ncig cov xov hlau thiab muaj qhov kub siab dua. Txawm li cas los xij, qhov siab dua qhov purity ntawm 0Cr27al7MO2, lub zog ntawm cov hlau thiab oxidation tsis kam, tab sis qhov nkig ntau dua, yog li nws yuav tsum tau ua tib zoo saib xyuas. Nws yog qhov zoo tshaj plaws kom muaj lub Hoobkas cua nws mus rau qhov loj me, tus neeg yuav khoom tsuas yog rov qab mus thiab tau txais lawv tus kheej. Kuj tseem muaj qee qhov cub hluav taws kub kub, xws li 1400 degrees. Nws raug pom zoo kom siv HRE los ntawm Shougang, sedesMBO los ntawm Tebchaws Meskas, lossis Kanthal APM los ntawm Sweden (Yancheng Hongtai yog tus neeg muag khoom ntawm Kanthal los ntawm Sweden). Tau kawg, tus nqi kuj nce siab dua. Nyob rau hauv cheeb tsam Jiangsu, hluav taws xob cua sov xov hlau tsim los ntawm Yancheng Hongtai yog cov tuam txhab zoo tshaj plaws.

(3) Ceramic thiab iav factories. Nws raug nquahu kom siv HRE ncaj qha lossis cov xaim hluav taws xob xaim hluav taws xob xaim hluav taws xob, vim tias cov hluav taws xob hluav taws xob kub kub tuaj yeem tsim kev co. Lub sij hawm ntev hluav taws xob kev co tuaj yeem ua rau cov khoom siv hluav taws xob tsis zoo rau oxidize thiab txiav, ua paug cov khoom. Tsuas yog los ntawm kev xaiv cov khoom siv hluav taws xob zoo hluav taws xob tuaj yeem ua tiav cov txiaj ntsig zoo.
