Mchenga wa Ceramic wa Kutaya Foam Wotayika Chithunzi Chowonetsedwa

Ceramic Sand for Lost Foam Casting

Kufotokozera Kwachidule:

Mchenga wa Ceramic wa maziko ake umagwiranso ntchito bwino: zofunikira zochepa pazida zochizira mchenga, kugwiritsa ntchito mphamvu zochepa komanso kutsika mtengo pakukonza mchenga.Kuchuluka kwa mchenga kumafika 98%, kumatulutsa zinyalala zochepa.Chifukwa chakusowa kwa zomangira, mchenga wodzaza thovu wotayika umakhala ndi chiwongola dzanja chokwera komanso mtengo wotsikirapo, kufika pa 1.0-1.5kg/tani yakugwiritsa ntchito mchenga.

M'zaka zaposachedwa, mabizinesi otayira thovu otayika akhudzidwa ndi zinthu zambiri, zomwe zidapangitsa kuti omaliza omaliza azitha kutsika.Pakati pawo, kukwera mtengo kwa ma castings, chiwongolero chachikulu komanso kutsika kwatsika kwakhala mavuto atatu m'mabizinesi otaya thovu otayika ku China.Momwe mungathetsere mavutowa ndikuwongolera mtengo wazinthu zoponyera zinthu zidakalipo kale yakhala imodzi mwantchito zapamwamba kwambiri zamakampani oyambira.Monga tonse tikudziwira, kusankha mchenga pakuponya ndi gawo lofunikira pazochitika zonse.Mchenga ukapanda kusankhidwa bwino, zidzakhudza zochitika zonse.Chifukwa chake, mabizinesi otaya chithovu otayika ayenera kuyesetsa kwambiri pakusankha mchenga.

Malinga ndi deta zogwirizana, makampani ambiri foundry bwino kusankha kwawo mchenga, kukana miyambo otsika mtengo mchenga khwatsi kapena forsterite mchenga, ndi kugwiritsa ntchito mtundu watsopano wa foundry mchenga ceramic kukonza vuto kuponyera.Mchenga watsopanowu uli ndi ubwino wokhala ndi refractoriness wapamwamba, madzi abwino, mpweya wothamanga kwambiri komanso kuchulukana kofanana ndi mchenga wa quartz.Imathetsa zolakwika pakutulutsa mpaka kumlingo wina, ndipo yakhudzidwa kwambiri ndi makampani apadziko lonse lapansi.Mavuto akulu atatu a mtengo woponyera, chiwopsezo chambiri komanso mtundu wamabizinesi otayira thovu otayika achepetsedwa, ndipo mchenga wa ceramic nawonso wakondedwa ndi mabizinesi ambiri.

Ubwino

● High refractoriness (＞1800°C), itha kugwiritsidwa ntchito poponya zinthu zosiyanasiyana.Palibenso chifukwa chogwiritsa ntchito mchenga wosiyanasiyana malinga ndi zinthu.

● Mlingo wapamwamba wobwezeretsa.Kuchuluka kwa mchenga kumafika 98%, kumatulutsa zinyalala zochepa.

● Kuchuluka kwamadzimadzi komanso kudzaza bwino chifukwa chokhala ozungulira.

● 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 kusinthika kuwirikiza kawiri kuchuluka kwa nkhungu pa kulemera kwa unit.Itha kuchitidwanso mosavuta, kupulumutsa ntchito ndi ndalama zosinthira mphamvu.

● Kupereka kokhazikika.Kuthekera kwapachaka 200,000 MT kuti musunge mwachangu komanso mokhazikika.
