Loaʻa ka nui o ke one foundry i kēia mau ʻano:
1.Silica one: ʻO ka hui mineral nui ʻo SiO2.Silica sand hiki ke hoʻokaʻawale hou ʻia i ke one silica maoli, koho ʻia ke one kūlohelohe a me ke one silica artificial. Hoʻohana ʻia ke one silica maoli e like me ka hoʻoheheʻe ʻana a me ke one kumu no ka hoʻolei ʻana i ka hao hao ʻole, nā ʻāpana hao, nā ʻāpana hoʻoheheʻe liʻiliʻi a me ke kumu kūʻai kila - nui.
2.Non siliceous one: me nā ʻano like ʻole e like me ke one quartz, ke one limestone, etc. ʻO ke one ʻo Quartz he mea granular i hana ʻia e ka ʻohi ʻana i ka pōhaku quartz ma ke ʻano he kumu maka, me ke kala o ka waiū keʻokeʻo a i ʻole semi transparent. Hoʻohana maʻamau ia i ka hoʻolei ʻana, mea pale ahi.metallurgy.chemical ʻoihana a me nā māla ʻē aʻe. Hana ʻia ke one limestone ma ka ʻoki ʻana i ka limestone, me ka hui ʻana o ka mineral nui ʻo CaCO3.Hoʻohana ʻia ʻo ia e like me ka hoʻoheheʻe ʻana i ke one a me ke one kumu no ka hoʻolei kila. Eia kekahi, aia nā one chromite, one olivine, one bead. etc.
3. Ke one kūikawā: ke ho'okō 'ia ka hana wela ki'eki'e o ke one silica i nā koi no ka ho'ohana 'ana, ho'ohana 'ia ke one kūikawā e like me ke one zircon, ke one chromite a me ke one corundum.2, Hoʻohana ʻia e like me ke one one a i ʻole ke one lepo a i ʻole ka pauka no ka nui o ke kila kila a me nā ʻāpana kila.2O3. ʻO - ʻo ka hui minerala nui o ke one corunduml2O3, ka mea i hoʻohana ʻia ma ke ʻano he pūpū no ka hoʻolei kālā a me ka hoʻoheheʻe ʻana i ka ceramic.
Ma keʻano holoʻokoʻa, aia nā ʻano like ʻole o ka hoʻolei ʻana i ke one, a ʻo nā ʻano like ʻole o ka hoʻolei ʻana i ke one he kūpono no nā kaʻina hana pahu a me nā ʻano hoʻolei.
Hana mākou a hoʻokuʻu aku i ke one - kiʻekiʻe mullite foundry, palaoa foundry a me ka pauda foundry
