Mchenga wa Ceramic wa No-Bake sand kuponyera ndi mawonekedwe ozungulira okhala ndi makona otsika.Kuchuluka kwa zomangira utomoni kumafunika kutsika pogwiritsa ntchito mchenga wa ceramic.Maonekedwe a mpira wamchenga wa ceramic amapanga madzi abwino, omwe ndi osavuta kuti makina owombera pachimake aziwombera mchengawo.Cerasand ili ndi katundu wabwinoko kuposa mchenga wa Quartz pamaziko.Ili ndi refractoriness yayikulu, kukulitsa pang'ono kwamafuta, kokwanira bwino kwa angular, kuyenda bwino kwambiri, Kukana kwambiri kuvala, kuphwanya ndi kugwedezeka kwamafuta, kutsika kwamphamvu kwambiri.
Ubwino
● Good flowability ndi otsika angularity coefficient chifukwa cha mpira mawonekedwe a mchenga ceramic.Pogwira ntchito ndi chowombera pachimake, mchenga ndi wosavuta kupita kumakona ang'onoang'ono.Chifukwa chake, ipeza malo oponyera osalala.
● Mankhwala ambiri a mchenga wa ceramic ndi Al2O3 ndi SiO2.Ili ndi mphamvu yotsutsa kutentha kwambiri mpaka 1800 ℃.Mumchenga mulibe asidi kapena alkali.Chifukwa chake sichingakhudzidwe ndi utomoni kapena chitsulo chosungunuka.Mbali imeneyi imatha kupititsa patsogolo luso lapamwamba la kuponya.
● Kugawa kwa tinthu tating'ono kumayendetsedwa ndi sieving.Ceramic mchenga ndi yokumba foundry mchenga, kotero ife tikhoza kulamulira tinthu kukula kugawa kwa amafuna makasitomala.Ndipo zindapusazo zimachepa pamchenga.
● Mlingo wapamwamba wobwezeretsa.Onse Thermal ndi makina reclamation.Amapereka moyo wautali wogwira ntchito komanso kuchepetsa kugwiritsa ntchito mchenga.
● Kukomoka kwambiri.Mchenga wa Sintered Ceramic mawonekedwe ozungulira poyerekeza ndi njere zooneka ngati makona amalola kupatukana kosavuta ndi magawo opangidwa ndi zida zotayidwa komanso kugwa bwino zomwe zimapangitsa kuti zinyalala zocheperako komanso kuponyera bwino.
● Kukula kwapansi kwa Thermal ndi Thermal Conductivity.Kuponyera miyeso ndi yolondola kwambiri ndipo kutsika kwa conductivity kumapereka ntchito yabwino ya nkhungu.
● Kuchulukirachulukira kochepa.Monga mchenga wopangidwa ndi ceramic ndi pafupifupi theka lopepuka ngati mchenga wa ceramic wosakanikirana (mchenga wa mpira wakuda), zircon ndi chromite, ukhoza kukhala pafupifupi kuwirikiza kawiri kuchuluka kwa nkhungu pa kulemera kwa unit.Itha kuchitidwanso mosavuta, kupulumutsa ntchito ndi ndalama zosinthira mphamvu.Komabe, chidwi chiyenera kuperekedwa ku kuchuluka kwa binder kuwonjezera.
● Pamafunika 30-50% utomoni wocheperako kuposa mchenga wa silika kapena mchenga wa quartz.
● Zojambulazo zimakutidwa ndi zokutira pang'ono kapena zosakhalapo.
● Angagwiritsidwe ntchito ngati mchenga umodzi.
● Zinthu zokhazikika.Kuthekera kwapachaka 200,000 MT kuti musunge mwachangu komanso mokhazikika.

Kugwiritsa ntchito
● Gwirani ntchito ndi utomoni monga ng'anjo, Alkaline-phenolic, galasi lamadzi.
● High alloy cast steel ndi carbon steel.
● Chitsulo chochepa cha carbon ndi ma valve zitsulo zosapanga dzimbiri.
● Chitsulo chosapanga dzimbiri, chitsulo cha manganese, chitsulo chambiri cha chromium.
