Kev npaj ntawm siab-zog graphite silicon carbide crucible rau hlau smelting

Qhov kev npaj txoj kev npaj siab ntawm lub zogGraphite Silicon Carbide CrucibleRau cov hlau smelting suav nrog cov kauj ruam hauv qab no: 1) khoom siv khoom siv; 2) Kev sib xyaw ua ntej; 3) cov khoom kom qhuav; 4) CRUSHING THIAB NTSUAM XYUAS; 5) theem ob khoom npaj; 6) Kev sib xyaw theem nrab; 7) nias thiab moulding; 8) txiav thiab trimming; 9) Kom qhuav; 10) glazing; 11) Kev tua hluav taws xob thawj; 12) Ipregnation; 13) Kev Rho Hluav Taws Xob; 14) txheej; 15) Cov khoom tiav lawm. Tus crucule uas tsim kev siv cov mis tshiab thiab cov txheej txheem ntau lawm tau muaj zog kub-kub tsis kam thiab corrosion tsis kam. Qhov nruab nrab lub neej ntawm cov qauv crucible nyob rau hauv 7-8 lub hlis, nrog kev sib txawv thiab kev ua kom muaj zog sab hauv, lub zog loj, thiab cov thermal zoo. Tsis tas li ntawd, cov txheej ci ci thiab txheej rau saum npoo, nrog rau kev ua kom qhuav thiab txhim kho cov txheej txheem kev ua haujlwm ntawm kev tiv thaiv corrosion los ntawm kwv yees li 30%, nrog qib siab ntawm vitrification.

Hom qauv no cuam tshuam nrog kev ua teb tsis-ferrous metallurgy casting, tshwj xeeb tshaj yog cov kev npaj ntawm siab graphite silicon carbide crucible rau hlau smelting.

[Keeb kwm yav dhau los] Tshwj xeeb graphite silicon carbide crucai thiab corrosion-resistant, thiab siv cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv corrosion, thiab cov khoom siv xeb-resistant

Cov qauv tshwj xeeb uas twb muaj lawm Silicifess thiab cov txheej txheem ntau lawm tsim cov khoom lag luam nrog lub neej nruab nrab ntawm 55 hnub, uas yog luv heev. Kev siv thiab cov nqi ntau lawm txuas ntxiv ntxiv, thiab cov khib nyiab ntau dua yog tseem muaj ntau. Yog li, tshawb nrhiav hom kev hloov kho tshiab ntawm cov pob zeb uas tau sib dhos thiab cov txheej txheem crucigles yog qhov chaw crucibles muaj cov ntawv thov tseem ceeb hauv ntau yam tshuaj muaj tshuaj.

[0004] los daws cov teeb meem saum toj no, ib txoj kev rau kev npaj siab zog graphite silicon carbide crucaibles crucailing yog muab rau cov hlau. Cov khoom npaj tau npaj raws li cov qauv no tiv thaiv ntau dua thiab kev tiv thaiv kev tiv thaiv, thiab ua kom muaj kev pab cuam lub zog, thiab kev siv hluav taws xob ntev, ua kom muaj kev pab cuam lub zog, ua kom muaj kev pab cuam lub caij.

Qhov npaj npaj ntawm high-zog graphite silicon carbide crucaibles rau hlau smelting suav nrog cov kauj ruam hauv qab no:

1. Cov Khoom Siv Khoom Siv Raw: Silicon carbide, graphite, av nplaum, thiab nws yog cov plc kev pab cuam tawm los ntawm crane, thiab qhov hnyav cia li muab tso rau hauv cov khoom siv raws li cov khoom siv uas tsim nyog. Pneumatic kev tswj hwm qhov paug, thiab tsawg kawg yog ob lub sensors tau teeb tsa hauv qab ntawm txhua lub Hopper. Tom qab hnyav, cov ntaub ntawv tau muab tso rau hauv ib lub tshuab sib xyaw los ntawm lub laub tsis siv neeg. Thawj qhov ntxiv ntawm Silicon Carbide yog 50% ntawm nws cov nyiaj tag nrho.
2. Cov khoom sib xyaw thib ob: Tom qab cov ntaub ntawv raw yog tov rau hauv lub tshuab hopper, thiab cov ntaub ntawv hauv kev tso tawm hopper los ntawm lub thoob endator rau theem nrab kev sib xyaw. Cov cuab yeej tshem tawm hlau tau teeb tsa ntawm qhov chaw nres nkoj tawm ntawm lub thoob txwv ntawm lub thoob nruab nrab ntawm lub thoob txwv yog teeb tsa saum toj no hopper ntxiv dej thaum stiring. Cov dej ntxiv yog 10l / min.
3. Cov Khoom Siv Kom Qhuav: Cov khoom ntub dej tom qab tov yog qhuav hauv cov khoom qhuav ntawm qhov kub ntawm 120-150 ° C kom tshem tawm noo noo. Tom qab ua tiav ziab, cov khoom tau coj tawm rau ntuj txias.
4. Crushing thiab ntsuam xyuas: cov khoom qhuav clumped nkag mus rau hauv cov khoom siv crushing thiab kuaj xyuas cov khoom siv ua ntej dhau los ntawm kev sib tsoo txuas ntxiv, thiab ib txhij dhau los ntawm 60-mesh kuaj cov khoom. Hais kom loj dua 0.25mm tau rov qab los rau kev rov ua dua tshiab, crushing, thiab tshuaj ntsuam me dua 0.25mm tau xa mus rau kev cia siab.
5. Cov Khoom Siv Khoom Thib Thib Thib Thib Thib Parib: Cov ntaub ntawv tso tawm hauv kev tso tawm Hopper tau thauj rov qab mus rau lub tshuab batching rau theem nrab npaj. Qhov seem 50% ntawm silicon carbide ntxiv rau hauv kev npaj khoom ob. Cov ntaub ntawv tom qab npaj cov lus ob raug xa mus rau lub tshuab sib xyaw kom rov tov.
6. Cov kev sib xyaw theem nrab, thaum lub sijhawm sib xyaw theem nrab, cov tshuaj tshwj xeeb nrog cov viscosity yog ntxiv rau cov kev cia siab ntawm kev sib xyaw nrog cov kev nqus tshwj xeeb. Cov kev daws tshwj xeeb yog ntsuas los ntawm cov thoob uas hnyav thiab ntxiv rau cov hopper.
7. Nias thiab molding: Cov ntaub ntawv tom qab sib xyaw theem nrab tau xa mus rau ib qho kev nias lub tshuab tso rau lub tshuab. Tom qab thau khoom, kab ke, nqus tsev, thiab tu hauv pwm, cov ntaub ntawv tau nias nyob rau hauv iSostatic nias tshuab.
8. Kev txiav thiab trimming: qhov no suav nrog txiav qhov siab thiab trimming cov burrs crucible. Kev txiav ua tiav los ntawm lub tshuab txiav kom txiav cov crucible rau qhov kom siab, thiab burrs tom qab txiav yog txiav.
9. Kom qhuav: Tus ntoo ci ntsa iab, tom qab raug txiav thiab txiav rau hauv kauj ruam (8), yog xa mus rau qhov cub ziab kom ziab, nrog ziab kom qhuav ntawm 120-150 ° C. Tom qab ziab, nws tau khaws cia sov rau 1-2 teev. Lub qhov cub qhuav yog nruab nrog cua duct hloov kho cov kab ke, uas muaj ob peb cov phiaj yas yooj yim alinter. Cov phiaj xwm yooj yim no tau npaj rau ntawm ob sab sab hauv ntawm qhov cub qhuav, nrog ib tus cua sib hauv txhua ob lub phiaj txhuas. Qhov sib txawv ntawm txhua ob lub phiaj txhuas aluminium yog hloov kho kom tswj tau huab cua.
10. GLAZING: Lub ci ci yog ua los ntawm nws cov ntaub ntawv ci nrog dej, suav nrog cov bentonite, feldspar hmoov, thiab sodium carboxymethyl cellulose. Lub ci ci yog thov manually nrog txhuam txhuam thaum glazing.
11. Thawj qhov hluav taws kub: Crucible nrog kev thov ci ci yog rho tawm ib zaug hauv ib lub Kiln rau 28-30 teev. Txhawm rau txhim kho kev tua hluav taws, chav Labyrinth Kiln txaj nrog cov nyhuv sib khi thiab cov thaiv huab cua yog teem rau hauv qab ntawm kiln. Lub txaj kiln muaj qab txheej ntawm kev xaws paj rwb, thiab saum toj no cov txheej ntawm rwb thaiv tsev rwb thaiv tsev, sib sau ua ib labyrin sai.
12. Impregnation: Cov neeg tua hluav taws tau muab tso rau hauv lub tshuab luam tawm impregnation rau lub tshuab nqus tsev thiab siab impregnation. Txoj kev daws teeb meem Impregnation tau thauj mus rau Impregnation tank los ntawm kev kaw lus raj, thiab lub sijhawm Impregnation yog 45-60 feeb.
13. Kev tua neeg tua hluav taws theem nrab: tus crucibnated crucible yog muab tso rau hauv ib lub Kiln rau theem nrab kev tua hluav taws rau 2 teev.
14. Cov txheej: tus crucible tom qab kev tua hluav taws theem nrab yog coated nrog cov dej uas muaj acrylic rov pleev xim rau saum npoo.
15. Cov khoom tiav: tom qab txheej tiav tiav, cov saum npoo yog qhuav, thiab tom qab ziab, tus ntoo ci, yog tus ntoo khaub zig thiab khaws cia.
