Refractory Ceramic Distributing Launder rau Aluminium billet casting
Lub tshuab ntxhua khaub ncaws faib khoom siv rau hauv lub rooj pwm casting ntawm lub tshuab casting, tshwj xeeb tshaj yog haum rau kev kub-sab saum toj casting rau txhuas thiab txhuas alloy.
Lub tshuab ntxhua khaub ncaws faib khoom yog ua los ntawm cov txhuas silicate fiber thiab cov khoom siv ceramic composite. Nws muaj cov yam ntxwv ntawm lub zog siab; tiv taus kua txhuas etching, siv tau ntev tsis yog khib nyiab, lub neej ntev, thiab zoo rwb thaiv tsev. Nws yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm casting.
Kev faib khoom ntxhua khaub ncaws feem ntau yog qhov loj me rau cov billets xws li 3 ", 4", 5 ", 6", 7 ", 8", 9 ", 10", 12 ", 14", 16 ", 18", 20 ", thiab kuj tuaj yeem tsim ntau qhov ntau thiab tsawg raws li cov neeg siv khoom xav tau.
| Qhov Ceev Kg/m3 | 135-145 |
| Lub zog flexural Mpa | >6 |
| SiO2 | 60% |
| Al2O3 | 15% |
| CaO | 15% |
Cov yam ntxwv tseem ceeb ntawm cov khoom siv fused silica ceramic yog kev ua haujlwm zoo thermal rwb thaiv tsev, tiv taus kub siab, txhuas tsis lo, muaj zog siab, tsis muaj delamination, thiab lub neej ntev. Cov txheej txheem ua haujlwm ntawm cov khoom siv:
Kub siv ntev (℃): 1100
Kev faib tawm siv qhov kub thiab txias (℃): 1650
Kev ua kom sov (W/mk): <1
Qhov Ceev (kg/m3): 1830
Kev tiv thaiv kev tawg (kg/m2): Cov tshuaj lom neeg muaj pes tsawg leeg [SiO2]: ≥99.5
Thermal expansion coefficient (x10-6): Lub neej: 200 casting lub sijhawm lossis ntau dua lossis ntau dua 1 xyoos
1. Kev ua tiav geometric siab, yooj yim rau nruab.
2. Muaj zog heev, ua haujlwm ntev, thiab tus nqi txij nkawm qis.
3. Cov khoom siv sib xws thiab rwb thaiv tsev zoo.
4. Cov txhuas tsis lo, tsis muaj kuab paug rau txhuas yaj.
5. Kev tiv thaiv scour, corrosion tsis kam ntawm txhuas kua Daim ntawv thov Nws yog siv rau txhuas billet casting lub rooj, cov txhuas molten yog poured rau hauv lub pwm crystallizer los ntawm Distribution launder thaum lub sijhawm casting. Nws tuaj yeem ua tau raws li cov kev cai ntawm precision casting ntawm txhuas alloy.
Txhua qhov loj me tuaj yeem hloov kho, muab cov duab kos lossis cov qauv ua ntej yuav khoom.
