Nā pōhaku lepo maʻamau:Inā ʻoe e noʻonoʻo wale i ke kumukūʻai, hiki iā ʻoe ke koho i nā brick refractory maʻamau, e like me nā pōhaku lepo. He makaʻu kēia pōhaku lepo. He $0.5 ~ 0.7 wale nō ke kumukūʻai o kahi pōhaku lepo. Loaʻa iā ia ka laulā o nā hoʻohana. Eia naʻe, kūpono ia no ka hoʻohana? No nā koi, inā ʻaʻole i hoʻokō ʻia, hiki ke hoʻomau pinepine ʻia ma muli o ka ʻaʻahu a me ka waimaka, a ʻaʻole hiki ke hoʻohana maʻamau. ʻO ka mālama pinepine ʻana hiki ke alakaʻi i ka hoʻoponopono mua ʻana a me ka hōʻino ʻana i nā mea hana, ʻaʻole pono ke loaʻa.
ʻO nā pōhaku lepo he mau meaʻawaʻawa nāwaliwali, me ka nui o ke kino ma kahi o 2.15g/cm3 a me kahi mea alumina o ≤45%. ʻOiai ke kiʻekiʻe o ka refractoriness e like me 1670-1750C, hoʻohana nui ʻia ia i ka pae wela kiʻekiʻe o 1400C. Hiki ke hoʻohana wale ʻia kēia huahana e like me nā koi. ʻO ka mahana, kekahi mau'āpana koʻikoʻi,ʻaʻole kiʻekiʻe ka ikaika compressive mahana maʻamau o nā pōhaku lepo,ʻo 15-30MPa wale nō, pili kēia i nā mea hōʻailona huahana,ʻo ia hoʻi ke kumu o ka maʻalahi o nā pōhaku lepo.
ʻO nā pōhaku kiʻekiʻe alumina refractory:Loaʻa i nā pōhaku lepo alumina kiʻekiʻe nā helu ʻehā ma muli o ka alumina. No ka mea ʻoi aku ka kiʻekiʻe o ka alumini o nā mea maka ma mua o nā pōhaku lepo, ʻo ka inoa kiʻekiʻe alumina pōhaku mai kēia. Wahi a ka papa, hiki ke hoʻohana ʻia kēia huahana i ka pae wela kiʻekiʻe o 1420 a 1550 ° C. Ke hoʻohana ʻia, hiki ke ʻike ʻia i ke ahi. ʻO ka ikaika compressive wela maʻamau e like me 50-80MPa. Ke ʻike ʻia i ke ahi, ʻaʻole hiki ke kiʻekiʻe ka mahana o ka ʻili ma mua o ka mahana hana. Hoʻopili nui ʻia kēia e ka nui o ka huahana a me ka ʻike alumina.
Nā pōhaku lepo:He kiʻekiʻe ka refractoriness a me ka wela hana kiʻekiʻe. Loaʻa iā lākou ma nāʻano kaumaha a māmā. ʻO nā pōhaku lepo nui me nā pōhaku lepo mullite i hoʻohui ʻia a me nā pōhaku lepo mullite sintered. He maikaʻi ke kūpale Thermal shock o ka huahana; ʻO nā huahana māmā loaʻa ka hopena insulation thermal maikaʻi. ʻO nā huahana māmā: JM23, JM25, JM26, JM27, JM28, JM30, JM32. Hiki ke ʻike ʻia nā huahana mullite moʻo māmā i ke ahi, a ua māhele like ʻia nā pores E like me ka kikoʻī kikoʻī a me ka ʻike maka o ka huahana, hiki ke hoʻohana ʻia ʻo JM23 ma lalo o 1260 degere, JM26 ma lalo o 1350 degere, a hiki ke hoʻohana ʻia ʻo JM30 i ka kiʻekiʻe wela laulā o 1650 degere. ʻO ia hoʻi ke kumu o ka pipiʻi ʻana o nā pōhaku lepo mullite.
Piliki Corundum:ʻO ka pōhaku lepo Corundum he brick refractory kiʻekiʻe me kahi mea alumina ma mua o 90%. Loaʻa i kēia huahana nā huahana sintered a hui pū. E like me nā mea maka, nā huahana nā: fused zirconium corundum brick (AZS, fused cast brick), chromium corundum brick, a me nā mea'ē aʻe. o 1,700 degere. ʻO ke kumukūʻai o kēia brick refractory e ʻokoʻa mai nā tausani a hiki i ʻumi kaukani yuan no ka ton ma muli o nā kumu e like me ke kaʻina hana a me ka ʻike maka.
ʻO nā pōhaku lepo pōʻalo alumina:ʻO nā pōhaku lepo pōleʻa alumina he mau pōhaku makamae maʻalahi, a hiki i ka RMB 10,000 no ke tona. Ma muli o nā ʻano hoʻohana like ʻole a me nā kaʻina hana, e komo pū me ka alumina, a me nā mea ʻē aʻe, pono ke kiʻekiʻe ke kumukūʻai o ka huahana. , e like me ka ʻōlelo, waiwai no ke kālā.
ʻO ka mea i luna nei he hoʻolauna i ka density, ke kūpaʻa kiʻekiʻe o ka mahana a me ke kumukūʻai o nā brick refractory. ʻO ka maʻamau, ana ʻia ka nui o nā mea refractory ma mua o ka haʻalele ʻana i ka hale hana. Ka nui o ka leo: hōʻike i ka lakio o ka nuipaʻa o ka hua maloʻo i kona nui nui, i hōʻike ʻia ma g/cm3.
