Tus nqi ua tau zoo piv ntawm cov hluav taws xob hluav taws xob txawv teb chaws thiab cov xaim hluav taws xob hauv tsev

:

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 qib: hlau chromium aluminium series thiab nickel chromium series.

Hauv cov hlau chromium aluminium, nws tau muab faib ua {{0}}cr25AL5, 0cr21Al6Nb, 0Cr27Al7Mo2. Hauv nickel chromium, nws muab faib ua Cr20Ni80, Cr15Ni60, Cr20Ni35, thiab Cr25Ni20

Imported hluav taws xob cua sov hlau

Yuav ua li cas xaiv cov khoom sib txawv ntawm cov hluav taws xob cua sov hlau raws li lawv cov kev siv sib txawv?

Yog tias tus neeg yuav khoom yog lub Hoobkas khoom siv tshuab, ntim tshuab, tshuab sealing, ntim tshuab, thiab lwm yam uas tsis tas yuav tsum muaj qhov kub thiab txias li ntawm {{0}}} degrees, nws raug nquahu kom siv nickel chromium hlau ntawm 0cr20Ni80 qib. . Nickel chromium hlau muaj qhov zoo weldability, yog mos, tsis yooj yim rau embrittle, thiab nws yog qhov zoo dua los siv daim kab xev tiaj vim tias lub zog thauj khoom ib square meter ntawm daim kab xev tiaj tus loj dua li ntawm cov kab hlau puag ncig, qhov dav yog siab dua, thiab tus nqi poob. yog me dua ntawm cov kab hlau.

Yog tias tus neeg yuav khoom yog lub tshuab hluav taws xob rau lub tshuab hluav taws xob, lub tshuab cub hluav taws xob, thiab lwm yam, cov teeb meem kub thiab kub yuav tsum tau txiav txim siab. {{0}}} degrees Celsius tsis xav tau qhov zoo tshaj plaws. Nws raug pom zoo kom siv cov hlau zoo tib yam chromium aluminium 0cr25al5, uas yog pheej yig dua thiab siab dua ntawm tus nqi. Kev khiav hauj lwm kub yog 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 900-1000 degrees Celsius, nws raug nquahu kom siv 0cr21al6nb. Hom hluav taws xob cua sov hlau 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 hlau 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 yuav tsum tau ua tib zoo saib xyuas kom ntseeg tau tias lub Hoobkas cua nws mus rau qhov tsim nyog loj, tus neeg yuav khoom tsuas yog rov qab mus thiab tau teeb tsa lawv tus kheej. Qee lub qhov cub muaj qhov kub ntawm 1400 degrees Celsius, thiab nws raug nquahu kom siv Sedes fca MBO los ntawm Tebchaws Meskas lossis Kanthal APM los ntawm Sweden. Tau kawg, tus nqi kuj nce siab dua
