He aha ka mea ʻoi aku ka ikaika kiʻekiʻe i ka lole palaki

Kiʻekiʻe-ikaika aahu-kūpaʻa plastic refractoryhe ʻano ʻano mea refractory ʻaʻole i hoʻolālā ʻia no ka hoʻohana ʻana i nā kūlana kiʻekiʻe, abrasive, a me nā kūlana erosive ikaika. Hōʻike ia i ka plasticity ikaika, ka hana kūpono, ka ikaika kiʻekiʻe, a me ke kūpaʻa maikaʻi loa, a hoʻohana nui ʻia ma ke ʻano he pale i loko no nā mea hana wela kiʻekiʻe ma nā ʻoihana e like me ka mana, metallurgy, cement, a me ka ʻenekinia kemika. ʻO nā mea waiwai kumu no ka ikaika kiʻekiʻe a me ka ʻaʻahu hiki ke pale i nā mea plastik:
ʻO nā hui a me nā pauka: ʻO ka bauxite alumina kiʻekiʻe, corundum, silicon carbide, chromite one, a me nā mea paʻa paʻa ʻē aʻe i koho ʻia e hana i ka iwi iwi, e hoʻoholo ana i ka pale ʻana a me ke kūpaʻa wela kiʻekiʻe.
Nā mea hoʻopaʻa: Aia nā mea hoʻopili hydraulic (e like me ka aluminate cement) a me nā mea hoʻopaʻa kemika (e like me ka phosphoric acid a me ka phosphate), hiki ke ho'ōla ʻia ma ka lumi wela me ka ʻole o ka sintering kiʻekiʻe.
Nā mea hoʻohui: Hoʻohui i nā mea hoʻemi wai, plasticizers, a me nā mea anti-cracking agents e hoʻonui i ka hana a me ka pale ʻana i ka wā o ke kūkulu ʻana; e hoʻohui i nā fiber metala a me nā fibers seramika e hoʻomaikaʻi i ka pale ʻana i ka hopena a me ke kūpaʻa haʻalulu wela.
ʻO nā hiʻohiʻona hana o ka mea paʻa kiʻekiʻe e hoʻopaʻa ʻia:
"Plastic refractory material":e pili ana i nā mea refractory e hōʻike ana i ka plasticity maikaʻi ma ka lumi wela (e like me ka plasticine), a hiki ke kūkulu ʻia ma o nā ʻano hana e like me ka ramming a me ka uhi ʻana, me ka ʻole o ka haʻalulu no ka hana ʻana.
"Ka ikaika kiʻekiʻe a me ke kūpaʻa ʻaʻahu": Ma ka hoʻohui ʻana i nā aggregates paʻakikī e like me corundum, silicon carbide (SiC), mullite, a me ke kiʻekiʻe-alumina clinker, a me ka hui pū ʻana me ka phosphate, calcium aluminate cement, a i ʻole nā mea hoʻopaʻa organik, loaʻa iā ia ka ikaika compressive kiʻekiʻe ma ke ana wela /ke wela kiʻekiʻe (≥60 MPa ma hope o ka maloʻo ʻana ma 118 ℃, ≥ ≥ 5 ℃ ma hope o ka hoʻomaloʻo ʻana i ka 118 ℃, MP3 ≥. ke kū'ē (ʻaʻahu poho ≤5 cm³, ʻoi aku ka maikaʻi ma mua o nā castable maʻamau)
ʻO ka ʻokoʻa nui ma waena o ka plastic wear-resistant kiʻekiʻe a me ka plastic maʻamau aia i:
ʻĀpana hoʻoikaika paʻa ʻana i ka lole:Hoʻonui hou ʻia nā mea paʻa kiʻekiʻe me nā mea paʻakikī paʻakikī e like me ka silicon carbide a me ka corundum, a i ʻole nā mea hoʻopaʻa ʻaʻahu metala, e hopena i ke kūpaʻa ʻana he 2-3 mau manawa kiʻekiʻe ma mua o nā mea plastik maʻamau.
Nā hōʻailona ikaika:Hōʻike ia i ka ikaika compressive kiʻekiʻe ma nā lumi ʻelua a me nā wela kiʻekiʻe, e kūpono ana i nā kūlana hana paʻakikī me ka hopena kiʻekiʻe a me nā ukana kaumaha. ʻO ka hoʻohālikelike, ʻoi aku ka maikaʻi o nā mea plastik maʻamau no ka insulation thermal a i ʻole nā noi lining auxiliary me ka lole haʻahaʻa a me ka waimaka.
