Sintered Ceramic Sand for Foundry

Kufotokozera Kwachidule:

Ceramic foundry sand ndi yabwino kupanga njere yozungulira yomwe imapangidwa kuchokera ku calcined bauxite yopangira mchenga.

Zomwe zili mkati mwake ndi aluminium oxide ndi Silicon oxide.Mchenga wa sintered ceramic for foundry ndi umodzi mwamchenga wa ceramic womwe umapangidwa ndi sintered process mu ng'anjo ya Rotary.Ndizodziwika kwambiri ndi zotulutsa zazikulu komanso zotsika mtengo.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.

• Chigawo cha yunifolomu
• Kugawa kwakukula kwambewu yokhazikika komanso kuthekera kwa mpweya
• Kukana kwambiri (1825°C)
• Kukana kwambiri kuvala, kuphwanya ndi kutenthedwa kwa kutentha
• Kuwonjezeka pang'ono kwa kutentha
• Kuchuluka kwamadzimadzi komanso kudzaza bwino chifukwa chokhala ozungulira
• Mlingo wapamwamba kwambiri wobwezeretsanso mumchenga wa loop system

Kugwiritsa Ntchito Sand Foundry Njira

RCS (mchenga wokutidwa ndi resin)
Cold box mchenga ndondomeko
3D kusindikiza mchenga ndondomeko (Phatikizani Furan utomoni ndi PDB Phenolic utomoni)
Njira ya mchenga wosaphika (Phatikizanipo utomoni wa Furan ndi Alkali phenolic resin)
Njira yopangira ndalama / Kutayika kwa sera yotayika / Kuponyera mwatsatanetsatane
Njira yotaya thupi / Kutaya thovu
Madzi galasi ndondomeko
