Hauv cov chaw tsim khoom, cov thawv tseem ceeb tsim cov resin, xuab zeb, thiab tso cov neeg ua haujlwm dhau sijhawm. Qhov kev tsim no clogs vents, tiv thaiv cov tub ntxhais kom zoo, ua rau muaj qhov tsis xws luag, thiab ua rau cov khoom seem. Kev tu ib txwm siv -siv phau ntawv scraping, chemical soaking, lossis abrasive blasting- siv sij hawm ntau teev. Nws yuav tsum tau txias lub thawv, disassembly, thiab feem ntau puas ilv vents los yog cov ntxaij vab tshaus. Lub sijhawm ua haujlwm poob qis, cov nqi zog nce, thiab cov khib nyiab thib ob xav tau tuav.
Qhuav dej khov blasting hloov qhov ntawd. Nws siv cov khoom CO₂ pellets nrawm nrawm los ntawm cov cua compressed los ntxuav cov thawv ntawv kom sai, nyab xeeb, thiab tsis muaj cov khib nyiab. Cov txheej txheem ua haujlwm thaum lub thawv tub ntxhais tseem kub thiab nyob rau hauv qhov chaw - tsis muaj qhov txias, tsis muaj kev sib cais. Foundries pom lub sij hawm tu lub sij hawm poob los ntawm teev mus rau feeb, downtime txo mus txog rau 86%, thiab cov cuab yeej tiv thaiv los ntawm kev puas tsuaj.
Kab lus no piav qhia txog kev tshawb fawb, cov txiaj ntsig tseem ceeb, cov txiaj ntsig tiag tiag los ntawm cov chaw tsim khoom, thiab yuav tsum xav txog dab tsi thaum siv cov dej khov qhuav qhuav rau kev tu lub thawv tseem ceeb.
Kev Tshawb Fawb Tom Qab Qhuav Ice Blasting
Qhuav dej khov blasting cia siab rau peb lub tshuab ua haujlwm ua ke.
Ua ntej, thermal shock. Cov dej khov qhuav qhuav ntawm -78.5 degree. Lawv khov residues zoo li hardened resin los yog xuab zeb instantly. Cov khoom sib cog lus, ua nkig, thiab poob adhesion rau saum npoo.
Thib ob, kinetic cuam tshuam. Compressed cua tua cov pellets ntawm kev kub ceev. Lawv tawm tsam cov seem khov thiab tawg mus rau hauv me me.
Thib peb, sublimation. Ntawm kev sib cuag, cov dej khov qhuav tig ncaj qha los ntawm cov khoom rau roj. Lub ntim nthuav dav ze li ntawm 800 npaug hauv micro- tawg uas nqa cov khib nyiab pov tseg. Cov roj CO₂ tsuas ploj mus - tsis muaj qhov seem seem.
Tsis zoo li sandblasting los yog hlaws blasting, cov dej khov qhuav tsis yog - abrasive thiab tsis yog - kev sib cuag hauv kev puas tsuaj. Nws ntxuav tsis muaj eroding hlau, hloov qhov ntev, los yog ua phem rau precision nta xws li vents thiab cov ntxaij vab tshaus. Qhov tsuas yog qhov uas yuav tsum tau tshem tawm yog thawj cov kab mob, feem ntau nqus tau yooj yim.
Qhov kev sib xyaw ua ke no ua rau cov dej khov qhuav blasting zoo tagnrho rau cov tub ntxhais lub thawv geometries uas ua kom huv si yam tsis muaj kev puas tsuaj yog qhov tseem ceeb.
Yuav Ua Li Cas Qhuav Ice Blasting Boosts Core Box Cleaning Efficiency
Cov thawv tseem ceeb muaj qhov ua siab ntev, muaj qhov sib txawv, thiab cov ntxaij vab tshaus uas yuav tsum nyob twj ywm. Txhua yam kev puas tsuaj hloov qhov loj me thiab ua kom muaj qhov tsis xws luag.
Cov dej khov qhuav qhuav daws cov teeb meem no ncaj qha.
Nws ntxuav hauv - qhov chaw ntawm qhov kub thiab txias. Tsis tos kom txias. Tsis siv lub thawv offline rau disassembly. Cov kab ntau lawm ua haujlwm ntev dua.
Kev tu kom nrawm dhia nrawm heev. Dab tsi siv los siv 3-4 teev nrog phau ntawv lossis cov txheej txheem abrasive tam sim no tiav hauv 10-15 feeb. Ib tus neeg ua haujlwm tuav nws tsis yog ob lossis peb.
Cov qhov cua thiab cov ntxaij vab tshaus nyob tsis tu ncua. Qhov tsis yog -abrasive xwm tiv thaiv yaig los yog distortion. Tooling kav ntev dua, hloov cov nqi poob, thiab qhov tseeb qhov tseeb tuav ruaj khov.
Tsis muaj cov ntaub ntawv pov tseg thib ob. Pellet sublimate kiag li. Tsis muaj xov xwm pov tseg, tsis muaj dej khib nyiab los kho, tsis muaj tshuaj lom neeg koom nrog.
Casting zoo txhim kho. Cov vents huv txhais tau tias zoo dua cov tub ntxhais filling thiab solidification. Cov nqi khib nyiab poob vim qhov tsis xws luag los ntawm qhov txhaws txhaws ploj.
Cov txheej txheem muaj kev nyab xeeb dua rau cov neeg ua haujlwm thiab ib puag ncig. Tsis muaj VOCs, tsis muaj dej txaus ntshai. Nws ua raws li cov kev cai nruj dua thiab txo qhov raug rau cov tshuaj ntxuav hnyav.
Thaum lub sij hawm, cov nqi poob qis. Tsawg zog, tsis muaj kev yuav khoom, kev poob qis tsawg, thiab kev kho cov cuab yeej tsawg dua ntxiv rau ROI muaj zog.
Cov dej khov qhuav blasting ua haujlwm hla cov tub ntxhais lub thawv hom:
- Cov thawv txias
- Ib nrab core thawv
- Tshem cov core boxes
- Split core thawv
- Strickle core thawv
- Sab laug thiab sab xis - txhais tes lub thawv
- Loose pieces core thawv
- Gang core thawv
Txoj kev muab cov txiaj ntsig zoo ib yam tsis hais txog kev tsim qauv.

Qhov sib txawv qhia tias yog vim li cas ntau qhov chaw tsim khoom hloov. Cov dej khov qhuav qhuav tshem tawm qhov mob loj tshaj plaws -lub sijhawm, kev puas tsuaj, thiab pov tseg- hauv ib kauj ruam.
Tiag -Kev Tshawb Fawb Ntiaj Teb
Kev Txhim Kho Casting Group hauv Minnesota tau ntsib kev tu tawv nqaij ntawm qis-siab casting pwm thiab cov thawv tseem ceeb. Cov vis dis aus me me tshwj xeeb tshaj yog muaj kev cuam tshuam rau cov txheej txheem abrasive. Tom qab kuaj lub tshuab dej khov qhuav ntawm kev ua phem tag nrho, lawv pom tsis muaj kev puas tsuaj -txawm yog cov yam ntxwv zoo tshaj plaws. Thawj Tswj Hwm pom zoo yuav tam sim ntawd.
Tam sim no ib tus neeg ua haujlwm ntxuav cov pwm hauv 10 feeb thaum nws kub thiab hauv online. Ua ntej, ob mus rau peb tus neeg ua haujlwm xav tau 3-4 teev ib pwm lossis khub. Lub sijhawm poob qis 86%, thiab lawv txuag tau $400–500 rau ib lub pwm ntxuav. Abrasive tu yog ploj mus tag nrho.
MWS Friedrichshafen hauv lub teb chaws Yelemees tau siv cov dej khov qhuav rau cov tub ntxhais lub thawv tu ntau tshaj 12 xyoos. Complex geometry xav tau meej, zoo ib yam. Cov dej khov qhuav xa tawm yam tsis muaj cov khoom pov tseg thib ob lossis cov nqi pov tseg. Lub sij hawm ntxuav tau zoo tuaj txog li 60%, cov khoom puas tsuaj poob, thiab cov khoom seem poob. Lawv ntxuav tsis tu ncua los tiv thaiv kev tsim.
Cov xwm txheej no qhia txog kev nce ntxiv: kev hloov pauv sai dua, kev tiv thaiv cov cuab yeej, qis qis dua, thiab ntsuas cov nqi txuag.
Kev xav txog kev siv
Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws, tsom mus rau ob peb yam tseem ceeb.
Pellet loj feem ntau nyob ib ncig ntawm 3 hli rau qhov tseeb qhov chaw xws li core box vents. Cov khoom me me ua haujlwm rau qhov chaw mos; loj dua rau qhov hnyav dua.
Cua siab feem ntau khiav 80-100 psi. Kho raws li hom residue- qis dua rau qhov chaw rhiab, siab dua rau cov tawv tawv tawv.
Nozzle nrug thiab lub kaum sab xis teeb meem. Qhia cov neeg ua haujlwm kom tswj tau cov txheej txheem zoo ib yam. Qhov no tiv thaiv kev tsis sib xws thiab tswj kev siv dej khov qhuav.
Rau siab - cov kab ntim, xav txog cov tshuab ua haujlwm. Lawv txhim kho kev rov ua dua thiab cov neeg ua haujlwm pub dawb rau lwm yam haujlwm.
Cov hauv paus kev nyab xeeb suav nrog cov hnab looj tes insulated rau qhov kub thiab txias, tiv thaiv qhov muag, thiab qhov cua rau CO₂ hloov chaw. Cov suab nrov yog tswj tau nrog kev tiv thaiv kev hnov lus.
Xaiv cov khoom siv los ntawm cov chaw tsim khoom lag luam uas tau ntsib hauv cov ntawv thov kev tsim khoom. Kev ntseeg tau zoo ntawm cov pellet zoo thiab cov huab cua zoo ib yam ua rau muaj qhov sib txawv.
Xaus
Qhuav dej khov blasting muab cov txiaj ntsig tiag tiag rau kev ntxuav lub thawv tseem ceeb. Nws txiav tu lub sij hawm mus rau feeb, txo qis downtime mus txog rau 86%, tiv thaiv precision Cheebtsam, tshem tawm pov tseg, thiab txhim kho casting zoo. Foundries uas txais nws pom cov nqi khiav lag luam qis dua thiab mob taub hau tsawg dua los ntawm cov txheej txheem ib txwm muaj.
Raws li ib tug ua manufacturers ntawmqhuav ice blasting tshuabnyob rau hauv Suav teb, YJCO2 tsim cov cuab yeej tsim nyog rau cov kev sib tw tiag tiag. Peb lub tshuab txhawb nqa txhua lub thawv tseem ceeb nrog kev ua tau zoo thiab kev pabcuam hauv zos.
