Yuav ua li cas thiaj paub yog tias lub raj cua sov puas lawm

Yuav ua li cas los txiav txim siab seb lub raj cua sov puas puas tom qab lub raj cua sov tau muab xa mus rau cov xa khoom lossis kev thauj mus los, lossis yog tias nws tsis tsim cov cua sov thaum siv cov khoom siv?

Ib txoj hauv kev yooj yim heev: Peb txoj hauv kev ib txwm yog siv lub ntsuas ntsuas ntsuas seb puas muaj tus nqi tiv thaiv. Yog tias tsis muaj tus nqi tiv thaiv, nws qhia tau tias lub cua sov lub raj puas lawm. (Thaum lub sijhawm thauj mus los, tshwj xeeb tshaj yog thaum ntsib kev tsis lees paub kev xa khoom lossis kev xa khoom xa tuaj, yuav muaj kev puas tsuaj rau cov kav dej cua sov.)

Ntawm qhov tsis sib xws: yog tias muaj tus nqi tsis kam, tab sis lub raj cua sov ntawm cov khoom siv mus ncig ua si vim kev tiv thaiv tawm tom qab qhib qhov hloov, ces siv lub ntsuas hluav taws xob tiv thaiv los ntsuas qhov ntsuas kev tiv thaiv hluav taws xob. Qhov tsis muaj rwb thaiv tsev tiv thaiv qhia tau hais tias cov yeeb nkab tau xau hluav taws xob thiab siv tsis tau dua.

Kev xaiv cov khoom siv hluav taws xob cua sov yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm cov khoom siv

Xaiv qhov sib txawv hluav taws xob cua sov xov hlau rau qhov chaw sib txawv tsis tas yuav pheej yig dua qhov zoo dua, lossis kim dua qhov tsim nyog. Nws yog ib qho tseem ceeb tshwj xeeb kom ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv, thiab qhov thib ob, tus nqi yuav tsum tsim nyog. Hais tias yog, peb xav tau cov khoom uas muaj nqi-zoo. Peb tuaj yeem xaiv cov khoom siv hluav taws xob cua sov li cas?

Hluav taws xob cua sov xov hlau muab faib ua hlau chromium aluminium series thiab nickel chromium series raws li lawv qib.

Hlau chromium aluminium ntxiv muab faib ua {{0}}cr25AL5, 0cr21Al6Nb, 0Cr27Al7Mo2, thiab lwm yam.

Nickel chromium nruab nrab: Cr20Ni80, Cr15Ni60, Cr20Ni35, Cr25Ni20, thiab lwm yam.

Yam hom twg thiab cov kab hluav taws xob cua sov yuav tsum siv nyob rau hauv qhov xwm txheej twg?

Yog tias 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 {{0}} degree, nws pom zoo kom siv nickel chromium hlau ntawm 0cr20Ni80 npe. 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 cov khoom siv hluav taws xob muaj zog. poob tus nqi yog me dua li ntawm cov xov 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, nws yog ib qho tsim nyog yuav tau xav txog qhov kub thiab txias qhov teeb meem. Ntawm 100 degree -900 degree, qhov zoo tsis tas yuav tsum ua kom zoo dua. Nws raug pom zoo kom siv cov hlau chromium txhuas ntau tshaj plaws 0Cr25al5, uas yog pheej yig thiab tuaj yeem siv rau qhov kub siab tshaj ntawm 900 degree. 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 hais tias lub cub tawg nyob nruab nrab ntawm 900 degree thiab 1000 degree, 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 hais tias lub cub tawg kub yog nyob nruab nrab ntawm 1100 degree thiab 1200 degree, nws raug nquahu kom siv Ocr27al7mo2, uas muaj MO puag ncig hlau thiab muaj qhov kub thiab txias 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 nws yuav tsum tau ua tib zoo saib xyuas. Nws yog qhov zoo tshaj plaws kom 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. Qee lub qhov cub muaj qhov kub thiab txias ntawm 1400 degree, thiab nws raug nquahu kom siv sedes fca MBO los ntawm Tebchaws Meskas lossis kan los ntawm Sweden.
