1. Kodi mchenga wa ceramic ndi chiyani?
mchenga wa ceramic umakhala wopangidwa ndi mchere wokhala ndi Al2O3 ndi SiO2 ndikuwonjezedwa ndi zinthu zina zamchere. Mchenga wozungulira wopangidwa ndi ufa, pelletizing, sintering ndi grading process. Kapangidwe kake kakang'ono ka kristalo ndi Mullite ndi Corundum, wokhala ndi chimanga chozungulira, kukana kwakukulu, kukhazikika kwabwino kwa thermochemical, kutsika kwamafuta ochepa, kukhudzidwa ndi kukana abrasion, mawonekedwe agawidwe mwamphamvu. Mchenga wa Ceramic ukhoza kugwiritsidwa ntchito kupanga ma castings apamwamba kwambiri pogwiritsa ntchito njira zamtundu uliwonse.
2. Malo ogwiritsira ntchito mchenga wa ceramic
Mchenga wa Ceramic wagwiritsidwa ntchito kwambiri poyambira mitundu yambiri yaukadaulo waukadaulo, monga mchenga wotidwa ndi utomoni, njira yodzilimbitsa yokha (F NB, APNB ndi Pep-set), bokosi lozizira, bokosi lotentha, mchenga wosindikiza wa 3D, ndi njira yotayira thovu. .
3. Mafotokozedwe a mchenga wa ceramic
SND imatha kupereka mchenga wa ceramic wamitundu yosiyanasiyana. Popanga mankhwala, pali mchenga wambiri wa aluminium-oxide, mchenga wapakatikati wa aluminiyumu-osayidi ndi mchenga wocheperako wa aluminiyamu-osayidi, womwe umagwiritsidwa ntchito motsutsana ndi zinthu zosiyanasiyana zoponya. Onse ali osiyanasiyana tinthu kukula kugawa kukwaniritsa zofuna kasitomala.

6. Mitundu ya mchenga wapamadzi
Pali mitundu iwiri yamchenga yomwe imagwiritsidwa ntchito kwambiri, yachilengedwe komanso yopangira.
Michenga yomwe imagwiritsidwa ntchito kwambiri ndi mchenga wa silika, mchenga wa chromite, olivine, zircon, mchenga waceramic ndi cerabeads. Mchenga wa ceramic ndi cerabeads ndi mchenga wopangira, ena ndi mchenga wachilengedwe.
7. The refractoriness wa otchuka foundry mchenga
Mchenga wa silika: 1713 ℃
Ceramic mchenga: ≥1800 ℃
Mchenga wa Chromite: 1900 ℃
Mchenga wa Olivine: 1700-1800 ℃
Mchenga wa Zircon: 2430 ℃
