Thaum koj hnov 'qhov hnav-resistant', feem ntau cov neeg tam sim ntawd xav txog hardness. Rockwell qhov no, Brinell hais tias. Nws yog thawj tus lej uas txhua tus neeg thov rau, thiab ncaj ncees, nws yog qhov pib tsim nyog. Tab sis yog tias koj tau nyob hauv qhov kev ua si no ntev txaus, koj paub tias qhov twg qhov kev sib tham tiag tiag pib, tsis xaus. Kuv tau pom ntau qhov haujlwm kaw vim tias ib tus neeg tau xaj ib feem raws li qhov kev ntsuas qhov hnyav los ntawm cov ntawv teev npe, tsuas yog kom nws ua tsis tiav hauv ib lub lis piam. Qhov tseeb yog, hnav tsis yog ib tug yeeb ncuab; Nws yog kev sib xyaw ua ke ntawm kev puas tsuaj, cuam tshuam, adhesion, thiab feem ntau corrosion, tag nrho cov seev cev ua ke hauv ib puag ncig hnyav. Kev kho nws raws li qhov teeb meem ntawm ib sab yog qhov loj tshaj, thiab kim tshaj plaws, yuam kev koj tuaj yeem ua.
Cov Khoom Siv Maze: Nws tsis yog ib txwm hais txog hlau
Yog li koj xav tau ib yam nyuaj. Koj thawj qhov kev xav yuav yog mus rau high-chromium cam khwb cia hlau lossis cov cuab yeej hlau. Cov kev xaiv zoo, rau qee yam kev siv. Tab sis cia peb hais tias koj tab tom cuam tshuam nrog slurry twj impeller. Koj tau txais cov khoom siv hluav taws xob siab tawm ntawm qhov chaw, tab sis kuj muaj peev xwm ua rau muaj cov tshuaj chloride. Lub super-hard steel yuav tawg nyob rau hauv lub cavitation, los yog corrode nyob rau hauv lub grain ciam teb. Qhov no yog qhov twg alloy sib tham tau tob. Peb tau muaj kev vam meej, thiab kev ua tsis tiav, uas tau thawb peb mus rau ntau qhov kev daws teeb meem.
Kuv nco qab txog qhov project rau cov cement cog, kiv cua sib dhos ntsib kev puas tsuaj los ntawm cov plua plav plua plav. Peb sim tus qauv NM400 coj phaj. Nyuaj li cov rau tes, tab sis kev co thiab kev cuam tshuam me me los ntawm cov khoom loj ua rau qaug zog tawg ntawm cov ntsiab lus mounting. Lub hardness tuaj ntawm tus nqi ntawm toughness. Qhov ntawd yog lub sijhawm kawm. Peb hloov mus rau qis hardness tab sis siab dua toughness hlau nrog hloov kho carbide faib hauv microstructure. Nws hnav ntau tus sib npaug thiab tsis tawg. Tus nqi lifecycle poob qis heev, txawm tias cov khoom siv thawj zaug saib softer ntawm daim ntawv.
Qhov no yog vim li cas tuam txhab uas muag tiag tiag nkag siab qhov no, zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), tsis txhob muag khoom xwb; lawv yuav tsum nkag siab txog hom kev ua tsis tiav. Nrog lawv keeb kwm yav dhau plhaub molding thiab peev casting, lawv tuaj yeem ua si nrog cov metallurgy los ntawm cov kua hauv lub xeev. Nws yog ib qib sib txawv ntawm kev tswj piv rau tsuas yog machining bar Tshuag. Rau hnav-resistant qhov chaw, cov txheej txheem casting nws tus kheej tso cai rau tsim complex, ze-net-zoo geometry uas nyuaj rau tshuab, thiab koj tuaj yeem tsim cov yam ntxwv coj mus rau hauv ib feem ntawm cov ntaub heev-xws li tso ntau hnav-resistant alloys raws nraim qhov twg puas tshwm sim thickest.
Cov txheej txheem yog ib feem ntawm Kev Ua Haujlwm
Hais txog txheej txheem, qhov no yog lwm txheej feem ntau overlooked. Koj tuaj yeem muaj qhov zoo tshaj plaws alloy muaj pes tsawg leeg, tab sis yog tias qhov kev kho cua sov tawm, los yog lub casting txias tsis ncaj ncees lawm, koj tshuav ib feem uas nkig, muaj kev ntxhov siab sab hauv, lossis cov khoom tsis sib xws. Kuv tau pom qhov chaw uas tau ntsib txhua qhov kev tshuaj ntsuam xyuas tshuaj tsis ua tiav ntxov vim tias tom qab lub quenching yog nruj dhau lawm, tsim micro-cracks.
CNC machining tuaj ntawm no, tab sis nws yog ib qho kev ua las voos. Machining ib hardened hnav-resistant ib feem tsis zoo li machining me steel. Koj tab tom cuam tshuam nrog cov khoom uas tawm tsam rov qab. Cov cuab yeej hnav yog insane, thiab yog tias koj tsim kom muaj cua sov ntau dhau, koj tuaj yeem tshem tawm cov txheej txheem saum npoo uas koj tau ua haujlwm hnyav heev los tsim, tsim cov tawv nqaij mos uas hnav sai sai. Cov txuj ci yog paub txog cov kab ke: qee zaum koj tshuab ua ntej kev kho cua sov zaum kawg, qee zaum tom qab, thiab cov cuab yeej txoj kev thiab cov khoom noj yuav tsum hwm cov khoom siv. Ib lub khw uas tsuas yog lub teeb machining yuav tsis muaj kev teeb tsa lossis kev paub txog qhov no. Nws yog cov txheej txheem tshwj xeeb, ib qho uas sib koom ua ke nrog cov khoom tsim khoom.
Qhov kev sib koom ua ke no yog qhov tseem ceeb. Ib lub tuam txhab uas tuav ob qho tib si casting thiab machining nyob rau hauv ib lub ru tsev, zoo li QSY (koj tuaj yeem pom lawv txoj hauv kev ntawm https://www.tsingtaocnc.com), muaj qhov zoo. Lawv tuaj yeem txiav txim siab thaum ntxov: Rau qhov no crusher liner, peb yuav nrum nws mus rau 95% net zoo nyob rau hauv no high-manganese hlau, ces tsuas tshuab lub mounting interfaces kom tsis txhob cuam tshuam cov hauj lwm-hardened nto qauv. Cov txheej txheem zoo li kev xav no txuag nqi thiab khaws cia kev ua haujlwm. Nws tsis yog ib kauj ruam tsim khoom xwb; nws yog kev tsim-rau-tsim thiab tsim-rau-kev txiav txim siab.
Thaum tshwj xeeb Alloys tsis yog khoom kim heev
Tam sim no, mus rau thaj chaw txawv: cobalt thiab npib tsib xee-raws li alloys. Tus nqi tag ua rau tib neeg flinch. Koj tsis qhia cov no rau kev lom zem. Tab sis nyob rau hauv ib puag ncig uas kub-kub hnav raws li corrosion-xav tias valve rooj zaum hauv petrochemical cracker los yog turbine hniav nyob rau hauv ib tug kub gas txoj kev-lawv tsis yog ib tug txawj tej yam ntxiv; lawv tsuas yog qhov uas yuav ua haujlwm. Kev hnav ntawm no feem ntau yog oxidation thiab sulfidation ntawm 800 ° C +, ua ke nrog cov khoom erosive.
Peb tau sim ib feem ntawm stainless hlau nyob rau hauv ib tug high-kub tshauv-kub system. Nws zoo nkaus li nyob rau hnub ib. Tsis pub dhau ib hlis, qhov saum npoo tau oxidized thiab tawg tawm, thiab cov khoom siv hauv qab tau raug khawb tawm sai heev. Peb hloov mus rau nickel-based alloy nrog cov ntsiab lus chromium siab. Tus nqi hnav qeeb mus rau kev nkag mus vim tias cov hlau ua kom ruaj khov, ua raws li cov txheej txheem oxide uas tiv thaiv cov substrate. Ib feem hnav los ntawm maj mam tso cov txheej no thiab hloov kho nws, tsis yog los ntawm kev puas tsuaj ntawm cov khoom poob. Qhov ntawd yog lub tswv yim sib txawv ntawm kev hnav tsis kam rau tag nrho.
Qhov no yog qhov chaw foundry qhov kev paub nrog tshwj xeeb alloys yog qhov tseem ceeb. Casting cov ntaub ntawv no yog ib tug txawv tsiaj nyaum. Lawv muaj qhov sib txawv shrinkage, sib txawv fluidity, thiab yog wildly reactive yog hais tias cov cua nyob rau hauv lub qhov cub tsis tswj. Ib tug foundry uas casually hais tias yog, peb tuaj yeem ua qhov ntawd yam tsis muaj cov ntaub ntawv teev tseg yog tus chij liab. Koj xav tau cov ntaub ntawv pov thawj, zoo li keeb kwm ntawm kev tsim cov khoom ua haujlwm uas tau muaj sia nyob hauv thaj chaw. Nws tsis yog hais txog nchuav hlau; Nws yog hais txog kev tswj cov tshuaj lom neeg tsis txaus ntseeg thiab cov tshuaj tiv thaiv lub cev kom tau txais txiaj ntsig microstructure.
Qhov Zoo thiab Cov Ntsiab Lus
Nov yog qhov ua tau zoo mob taub hau uas tsis ua rau daim ntawv qhia: haum thiab kev teeb tsa. Koj tuaj yeem tsim lub ntiaj teb zoo tshaj plaws hnav-resistant liner, tab sis yog hais tias lub mounting qhov tawm los ntawm ib nrab ib millimeter, los yog yog hais tias ib feem warps me ntsis thaum lub sij hawm kho cua sov, tus haum rau ntawm qhov chaw yuav tsum tau zom nws kom haum. Koj tab tom sib tsoo tawm ntawm qhov chaw koj them tus nqi them rau. Kuv twb pom lawm. Lub siab ntev specification rau ib qho hnav tsis yog tsuas yog hais txog kev ua haujlwm; Nws yog hais txog installability. Qee lub sij hawm koj yuav tsum tau qhia kom meej raws li-cam khwb cia qhov chaw nyob rau hauv qhov chaw tsis tseem ceeb thiab machined nto tsuas yog qhov chaw mating tshwm sim. Nws yog tus nqi-kev ua tau zoo-kev teeb tsa daim duab peb sab.
Lwm cov ntsiab lus ntsiab lus: cov khoom siv mating. Ib feem ntawm kev hnav tsis kam yog qhov tsis muaj txiaj ntsig hauv kev sib cais. Nws yog qhov system. Ib qho super-nyuaj ceramic-coated chute liner yuav zoo heev tiv thaiv silica xuab zeb, tab sis yog tias nws tau raug ntaus los ntawm manganese steel rauj, koj yuav tau txais kev puas tsuaj loj. Qee zaum, koj xav tau cov khoom siv softer, ntau dua rau hauv ib feem ntawm qhov system los tiv thaiv qhov tseem ceeb, cov khoom kim heev hauv qab. Nws yog hais txog kev tswj txoj kev hnav los ntawm tag nrho cov txheej txheem, tsis yog tsuas yog yuav qhov nyuaj tshaj plaws rau txhua yam khoom.
Qhov kev xav-kev xav no yog dab tsi cais cov khoom lag luam los ntawm tus khub daws teeb meem. Nws yuav tsum tau nug ntau cov lus nug ua ntej: Nws hnav dab tsi tiv thaiv? Qhov kub thiab txias yog dab tsi? Puas muaj tshuaj lom neeg? Qhov cuam tshuam lub kaum sab xis yog dab tsi? Nws ntsia li cas? Dab tsi yog qhov kev cia siab lifecycle? Cov lus teb qhia txhua yam los ntawm kev xaiv cov khoom siv rau txoj kev casting mus rau tom qab ua tiav.
Saib Rov Qab Mus Rau Tom Ntej
Tom qab peb xyoos lawm, koj pom cov qauv. Cov tuam txhab uas nyob hauv daim teb no, zoo li QSY nrog lawv 30 xyoo, tsis yog nyob ntawm tus nqi xwb. Lawv tau tsim ib qhov chaw khaws cia ntawm kev txheeb xyuas tsis ua haujlwm thiab cov dab neeg ua tiav. Lawv tau kawm, feem ntau txoj kev nyuaj, uas a hnav-resistant ib feem yog kev cog lus ntawm uptime. Nws tsis yog khoom. Tus nqi tsis nyob rau hauv kilogram ntawm hlau; nws yog nyob rau hauv lub sij hawm ntawm kev ua hauj lwm nws xa ua ntej yuav tsum tau hloov.
Lub neej yav tom ntej, kuv xav tias, nyob rau hauv kev sib koom ua ke nruj dua ntawm kev tsim, cov ntaub ntawv tshawb fawb, thiab kev tswj cov txheej txheem. Tej zaum nws yog qhov kev simulation ntau dua ntawm cov qauv hnav thaum lub sij hawm tsim, los yog kev sim siab uas tsis muaj kev puas tsuaj los lav lub suab sab hauv hauv cov khoom cam khwb cia. Lub hom phiaj tseem zoo ib yam: kom phim cov khoom tsim nyog, zoo li tus thiab kho kom raug, mus rau ib qho tshwj xeeb ntawm kev puas tsuaj. Nws yog ib qho kev sib tw uas tsis tas yuav xaus, tab sis qhov ntawd yog qhov ua rau nws ua haujlwm tiag tiag. Nws yeej tsis yog hais txog hardness xwb. Tus neeg twg uas qhia rau koj tsis yog tej zaum tsis tau siv sijhawm txaus rau hauv pem teb kev saib xyuas, saib ntawm qhov ua tsis tiav thiab xav tsis thoob tias yuav ua li cas ntxiv.
