Ingot Moulds tsim los rau siab -Tsev ua haujlwm li cas?
Nyob rau hauv cov chaw smelting aluminium, cov txheej txheem ntawm casting molten aluminium rau hauv cov khoom, cov ntaub ntawv thauj mus los xav tau cov cuab yeej siv uas tuaj yeem tiv taus huab cua kub huab cua tom qab lub voj voog. Ibpwm ingotyuav tsum tau txais molten aluminium ntawm qhov kub thiab txias ib puag ncig lossis siab dua 660 degree, tiv taus qhov kev ntxhov siab thermal, thiab tso tawm ib qho huv si, tsim nyog zoo ib yam casting ib zaug hlau solidifies. Kab lus no tshuaj xyuas cov qauv tsim qauv tom qab ingot pwm tsim rau siab - kev pabcuam kub, npog cov khoom siv, kev tsim vaj tsev, thiab kev ntsuas kev ruaj ntseg uas ua ke txiav txim siab seb cov pwm yuav kav ntau lub hlis lossis xyoo hauv kev tsim khoom tas mus li.
Kev xaiv cov khoom siv: Lub hauv paus ntawm ib lub kav ntevIngot Pwm
Kev xaiv cov khoom siv yog qhov kev txiav txim siab tshaj plaws hauv kev tsim cov pwm pwm rau kev ua haujlwm txhuas. Molten aluminium yog poured ntawm kub tshaj nws 660℃melting point, thiab cov pwm yuav tsum nqus no thermal zog sai, ces txias thiab rov ua dua lub voj voog thoob plaws hauv nws lub neej ua haujlwm. Cov tsoos cam khwb cia hlau tau ntev dhau los ua tus qauv rau cov ntawv thov no vim nws cov khoom siv dag zog thiab muaj. Txawm li cas los xij, tsis yog txhua qhov cam khwb cia hlau ua tau zoo sib npaug hauv kev rov ua dua thermal cycling. Kev raug cua sov thiab cua txias ntev ua rau muaj kev ntxhov siab sab hauv uas ua rau tawg tawg thiab qhov tshwm sim ntawm cov txheej txheem tsis ua haujlwm. Qhov no yog vim li cas Xi'an Huan-Tai tau tsim nws cov khoom siv DuraCast®, tshwj xeeb steel formulation engineered los tiv thaiv qhov pib tawg hauv qhov xav tau ib puag ncig. Rau kev ua haujlwm uas siv cov dej txias kom nrawm cov khoom siv, cov thermal gradients ua rau hnyav dua. Hauv kev teb, Huan-Tai tau tsim cov qib tshwj xeeb ntawm cov khoom siv hlau uas tsis tshua muaj kev cuam tshuam rau hauv cov xwm txheej hnyav. Txawm hais tias cov nroj tsuag xaiv cov pa cam khwb cia hlau aluminium ingot pwm lossis DuraCast® kev xaiv, cov khoom siv yuav tsum muaj kev sib xyaw ua ke ntawm thermal qaug zog tiv thaiv, toughness, thiab seem stability. Xaiv cov khoom uas poob qis hauv ib qho ntawm cov chaw no yuav ua rau lub neej luv luv thiab ua rau cov nqi nce ntxiv mus rau lub sijhawm, ua cov khoom siv xaiv lub hauv paus tseeb uas txhua qhov kev txiav txim siab tsim.
Tus qauv tsim thiab geometry rau kev ntseeg siab Casting Performance
Nws tsis yog cov ntaub ntawv uas cuam tshuam zoo npaum li caspwm ingotua haujlwm ntawm qhov kub thiab txias; cov duab thiab qhov loj ntawm pwm nws tus kheej kuj tseem ceeb heev. Cov pwm yuav tsum muaj peev xwm ua kom zoo nrog cov hlau melted, harden nrog ob peb flaws, thiab yooj yim tawm ntawm pwm. Rau cov pwm me me, uas ua rau cov cam khwb cia uas hnyav li ob peb kaum kilograms, tus tsim tsom rau cov duab phab ntsa zoo li qub thiab cov kaum sab xis kom cov ingot hardened tau yooj yim tshem tawm ntawm cov pwm. Cov khoom me me no raug xa mus rau cov lag luam txuas ntxiv mus rau hauv kab, xws li tuag-casting thiab automakers, qhov chaw uas lawv tau rov ua dua - melted thiab siv nyob rau hauv lwm yam txheej txheem. Qhov tseeb heev hauv kev ntsuas tsis yog qhov tseem ceeb heev vim tias cov tuav yuav muab tso rau hauv qhov cub thiab boiled. Dab tsi tseem ceeb yog tias aluminium ingot pwm ua rau cov duab zoo nkauj txawm thiab yooj yim rau pawg, txav, thiab tuav. Sow pwm, ntawm qhov tod tes, yog qhov loj dua thiab tuaj yeem ua cov hlau hnyav hnyav nrog lub peev xwm hnyav ntawm 1,200, 1,500, thiab 2,000 phaus. Cov tuam txhab txhuas, ob qho tib si tseem ceeb thiab theem nrab, ua cov noob qoob loo no ua cov khoom lag luam uas lawv muag rau lwm qhov chaw smelting. Cov qauv ntawm txhua lub txhuas ingot pwm, tsis hais qhov loj npaum li cas, yuav tsum muaj cov kaum sab xis loj thiab cov phab ntsa sib npaug uas kis tau cov thermal kev nyuaj siab sib npaug thiab nres qhov kub kub uas ua kom tawg. Huan-Tai khaws cov khoom lag luam loj ntawm cov qauv rau ob qho tib si tus qauv thiab cov qauv tsim tshwj xeeb. Txoj kev no, lawv tuaj yeem ua kom paub tseeb tias txhua qhov pwm zoo tshaj plaws rau kev ua haujlwm casting thiab kev ua haujlwm.
Kev Ua Haujlwm Zoo: Ua kom txhua tus pwm pwm ua tau raws li qhov siab -Thov kom kub
Txawm tias cov khoom siv zoo tshaj plaws thiab cov kev xav geometry feem ntau tsis tuaj yeem lav qhov kev ua tau zoo yog tias kev tsim khoom tsis zoo. Qhov no yog vim li cas kev tswj xyuas kom zoo yog qhov tseem ceeb hauv kev tsim khoompwm ingotnpaj rau siab -kub aluminium casting. Xi'an Huan-Tai tsim tag nrho cov smelting pwm nyob rau hauv kev tswj cov txheej txheem nruj, thiab txhua pwm ua tiav Tsis yog-Kev kuaj kev puas tsuaj rau ob qho tib si saum npoo thiab subsurface discontinuities ntawm txhua qhov chaw uas hu rau molten aluminium. NDT txoj kev kuaj pom qhov tsis pom ntawm qhov muag liab qab - micro- tawg, porosity, lossis suav nrog uas tuaj yeem ua cov ntsiab lus pib rau thermal qaug zog tawg thaum ua haujlwm. Los ntawm kev txheeb xyuas thiab tshem tawm cov teeb meem no ua ntej pwm puas mus txog hauv pem teb cam khwb cia, tag nrho cov nqi ntawm cov tswv cuab poob qis heev. Ib qho txhuas ingot pwm uas tau raug tshuaj xyuas thiab xyuas kom zoo yuav xa cov kev pab cuam lub neej ntev dua, tsawg dua kev hloov pauv tsis tu ncua, thiab cov khoom tsim tawm zoo sib xws. Raws li ISO 9001 lub tuam txhab tau lees paub, Huan-Tai siv cov kev qhuab qhia zoo no ua haujlwm thoob plaws nws tag nrho cov pwm pwm rau cov khoom lag luam txhuas, muab cov neeg ua haujlwm ntseeg siab tias txhua pwm yuav ua tau kev ntseeg siab los ntawm nws thawj zaug mus rau qhov kawg.
