Dab tsi yog cov yam ntxwv thiab kev siv tau ntawm 601 alloy uas tiv taus kub oxidation?
Niaj hnub no, GNEE yuav tham txog 601 kub resistant alloy.
Alloy 601, UNS qib N06601, German tus qauv 2.4851, yog nickel-chromium alloy nrog zoo oxidation tsis kam ntawm qhov kub txog li 1180 degree. Txawm nyob rau hauv cov mob loj heev, xws li thaum cua txias Cycles, 601 alloy tseem tuaj yeem tsim cov yeeb yaj kiab desens oxide thiab ua kom tiav siab spalling tsis kam. Zoo carbonation kuj. Vim nws cov ntsiab lus siab chromium thiab txhuas, nws kuj tseem siv tau los tiv thaiv qhov kub ntawm oxidation hauv cov huab cua uas muaj leej faj. Nyob rau hauv chav tsev kub thiab kub siab, 601 alloy muaj cov khoom siv zoo thiab ua haujlwm zoo rau kev ntxhov siab corrosion tawg.
Qhov liab hauv qab no yog qhov muaj pes tsawg leeg ntawm 601 alloy (cov ntaub ntawv tshem tawm los ntawm ASTM B168 phaj tus qauv).
601 alloy ua thiab kev kho cua sov
Alloy 601 alloy yog ib qho yooj yim los ua cov txheej txheem kev lag luam. Txawm li cas los xij, vim nws lub zog siab, lub tshuab hluav taws xob siab yuav tsum tau ua kom txias thiab kub.
601 alloy preheating
Qhov saum npoo ntawm lub workpiece yuav tsum tau ntxuav ua ntej thiab thaum lub sij hawm cua sov txheej txheem kom huv si nto. Yog tias qhov cua sov ib puag ncig muaj leej faj, phosphorus, txhuas lossis lwm yam hlau uas tsis tshua muaj melting point, 601 alloy yuav nkig. Cov impurities tuaj ntawm cov xim pleev xim, chalk, lubricating roj, dej, roj, thiab lwm yam. Cov ntsiab lus ntawm cov roj sulfur yuav tsum tsawg. Piv txwv li, cov ntsiab lus impurity ntawm cov roj av liquefied roj av thiab cov nkev ntuj yuav tsum tsawg tshaj li 0.1%, cov ntsiab lus sulfur ntawm lub nroog cov pa yuav tsum tsawg dua 0.25g/m3, thiab cov ntsiab lus sulfur. roj av yuav tsum tsawg tshaj li 0.5%.
Lub tshuab hluav taws xob rau cua sov yuav tsum zoo dua muaj peev xwm tswj tau qhov kub thiab txias ntau dua thiab cov pa hluav taws xob ntau dua.
Yog tias cov ntsiab lus impurity ntawm cov roj tsawg, koj tuaj yeem txiav txim siab siv lub tshuab cua sov cua sov. Txawm li cas los xij, cov roj rau hauv lub cub tawg yuav tsum yog nruab nrab lossis tsis muaj zog alkaline, thiab kev hloov pauv hauv oxidizing thiab txo cov khoom ntawm lub cub tawg yuav tsum zam. Cov nplaim hluav taws kub tsis tuaj yeem hlawv ncaj qha mus rau qhov chaw ua haujlwm.
601 alloy kub ua
Qhov tsim nyog kub ua haujlwm kub rau 601 alloy alloy yog 1200-900 degree . Txoj kev txias tuaj yeem yog dej quenching lossis lwm txoj kev ua kom txias sai. Tom qab ua haujlwm kub, nws yuav tsum tau muab tso rau hauv lub sijhawm kom ntseeg tau tias qhov ua tau zoo tshaj plaws. Thaum lub sij hawm thermal ua, cov khoom yuav tsum tau rhuab mus rau lub sab sauv txwv ntawm ua kub.
Tom qab lub cub tawg mus txog qhov kub thiab txias, cov khoom yuav tsum sov li 60 feeb ib 100 hli thickness. Tom qab khaws cia sov rau lub sijhawm teev tseg, nws raug tso tawm tam sim ntawd thiab ua tiav hauv qhov ntsuas kub tau teev tseg. Yog hais tias qhov kub ntawm cov hlau poob qis dua qhov kev ua haujlwm tsawg kawg nkaus, nws yuav tsum tau muab rhaub dua.
601 alloy txias ua
Kev ua haujlwm txias yuav tsum tau ua tom qab kev kho cov kua dej khov kho. Kev ua haujlwm hardening tus nqi ntawm 601 alloy yog ntau dua li ntawm austenitic stainless hlau, yog li cov cuab yeej ua haujlwm yuav tsum raug kho raws li, thiab yuav tsum muaj cov txheej txheem nruab nrab annealing thaum lub sijhawm ua haujlwm txias. Thaum qhov txias deformation ntau dua 10%, qhov kawg kev daws yuav tsum tau kho.
601 alloy kub kho
Kev kho cua sov kub ntau ntawm 601 alloy yog 920-980 degree, thiab qhov haum tshaj plaws yog 950 degree .
Txhawm rau kom tau txais qhov kub thiab txias thiab kev ua haujlwm ruaj khov, qhov kub-kub tshuaj kho qhov kub ntawm 601 alloy yog 1100-1180 degree . Dej quenching muab qhov siab tshaj plaws creep tsis kam thiab cov pa roj carbon tsawg tsawg ntawm 500-800 degree . Cov khoom siv nrog lub thickness tsawg dua 3 hli kuj tuaj yeem ua cua txias sai.
601 alloy sib tsoo
Cov kub kub alloys yuav tsim cov yeeb yaj kiab oxide tiv thaiv thaum ua haujlwm. Yog li ntawd, ua tib zoo xyuas seb puas yuav tsum tau polishing.
Cov oxides nyob ze ntawm cov welds ntawm 601 alloy workpieces yog qhov nyuaj rau tshem tawm dua li cov hlau tsis muaj steel. Lawv yuav tsum tau polished nrog ib tug zoo sanding siv los yog sib tsoo log. Ua ntej pickling nyob rau hauv ib tug tov ntawm nitric acid thiab hydrofluoric acid, cov oxides yuav tsum tau muab tshem tawm nrog sandpaper los yog ntsev da dej pretreatment.
601 alloy machining
Lub machining ntawm 601 alloy yuav tsum tau ua tom qab kev daws teeb meem, thiab kev ua hauj lwm hardening ntawm cov khoom yuav tsum tau muab coj los xav. Tsis zoo li austenitic stainless hlau, 601 alloy yog haum rau qis nto txiav ceev thiab hnyav pub.
601 alloy vuam
Ua ntej welding, cov khoom yuav tsum nyob rau hauv ib qho annealed los yog tov-kho lub xeev, thiab saum npoo yuav tsum huv si, tsis muaj roj stains, chalk marks, thiab lwm yam. 25 hli cheeb tsam nyob ib ncig ntawm lub weld yuav tsum polished kom pom cov hlau ci. Qhov kub ntawm qhov sib cuam tshuam tsis tshaj 120 degree, thiab tsis tas yuav tsum muaj kev kho cua sov ua ntej lossis tom qab vuam.
Cov khoom siv vuam pom zoo:
Welding rod AWS A 5.11 ENiCrFe-3
Welding wire AWS A 5.11 ENiCrCoMo-1
