Hoʻohana ʻia ke one Foundry ma ke ʻano he mea hoʻoheheʻe granular no ka hoʻoheheʻe ʻana i ke one a me ke one kumu i ka hana ʻana.I ka hihia o ka hoʻohana ʻana i ka pālolo ma ke ʻano he paʻa one hoʻoheheʻe ʻia, no kēlā me kēia tona o nā hoʻoheheʻe kūpono i hana ʻia, pono ia e hoʻohui i 1 ton o ke one hou.No laila, hoʻohana ʻia ka nui o ke one foundry i ka hana hoʻolei ʻana i ke one.
I ke kenekulia 17, ua hoʻohana ʻo Kina i ke one silica ma ke ʻano he mea hoʻoheheʻe ʻia e hana ai i nā pahu e like me nā uaki, nā aniani, nā ipuhao a me nā pū.Eia nō naʻe, ʻo ka hapa nui o ia one he one silica maoli, ʻo ia hoʻi ke one mauna a me ke one kahawai, ʻoi aku ka maikaʻi o ka palaka a hiki ke hoʻohana pololei ʻia no ka hana ʻana i nā mole a me nā koʻi.Ma hope o ke komo ʻana o ka hoʻoheheʻe ʻana i ka hana nui o ka ʻoihana, ʻoi aku ka maikaʻi ma hope o ka mechanization o ka hoʻohālikelike ʻana, ʻaʻole maikaʻi ke kūlike o ke one silica maoli i loko o ka pālolo, a paʻakikī ka maikaʻi o ke one molding, ʻaʻole hiki ke hoʻokō i nā koi kaʻina.No laila, ua hoʻomaka ʻia kahi mea kanu one e hana i ke one silica maoli e Scrubing, e koho ana e kiʻi i nā ʻano one silica ʻē aʻe.Ma waho aʻe o kēia, hana ʻia ke one silica artificial ma ka ʻoki ʻana i ka silica.I ka manawa like, hoʻonui ia i ka noi a me ka hoʻomohala ʻana i nā ʻano like ʻole o ka resin resin resin a me nā kaʻina hana kumu, a waiho i nā koi kiʻekiʻe no ka maikaʻi o ka hoʻolei ʻana i ke one, e like me ka pauka liʻiliʻi, ka palena kikoʻī liʻiliʻi, a me ka haʻahaʻa. ʻaiʻakika.No laila, ua hoʻomohala kekahi mau ʻāina i nele i nā kumu one kiʻekiʻe no ka nui o ke one.

Pono ke one hoʻokumu i kēia mau koi: ① ʻoi aku ka maʻemaʻe a me ka maʻemaʻe, e lawe ana i ke one silica i laʻana, pono ke one no ka hao hao iā SiO₂ʻoi aku ma luna o 90%, pono nā ʻāpana kila i hoʻolei ʻia iā SiO₂ʻike ma luna o 97%;② pale ahi kiʻekiʻe Degree a me ke kūpaʻa wela;③ ʻO ke ʻano o nā ʻāpana kūpono a me ka hoʻohui ʻana i nā ʻāpana;④ ʻAʻole maʻalahi i hoʻopaʻa ʻia e ka metala wai;⑤ Maikaʻi a maʻalahi ke loaʻa.
Mai ka makahiki 1951, ua hana ʻo Kina i ka helu helu ʻana i nā kumuwaiwai one foundry i ka holomua, akā aia ma kahi kokoke i nā laina kaʻa nui a me nā kūlanakauhale ʻoihana nui.Ma Zhelimeng, Inner Mongolia, ka nui o ke one silica kūlohelohe i nā haneli miliona o nā tona, a ua kokoke kona ʻano ʻāpana i kahi pōʻai, a ʻo ka SiO₂ʻO ka ʻike ma kahi o 90%, kūpono loa ia no ka hoʻolei ʻana i ka ʻoihana.Ke one kai o Jinjiang, Dongshan, Fujian, ka SiO₂ʻO ka maʻiʻo he 94 ~ 98%.Aia ka nui o ka muliwai Quaternary a me ke one sedimentary silica ma Duchang, Xingzi, Yongxiu County, Jiangxi Province.ʻO ka SiO₂ma kahi o 90%.Aia i loko o Guangzhou a me Hunan ka pōhaku one momona a palupalu.Kona SiO₂ʻoi aku ka maʻiʻo ma luna o 96%, hiki ke hoʻohana ʻia no ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, liʻiliʻi alkaline oxides, ka nui o nā ʻāpana like ʻole.
