Kiʻekiʻe wela pale refractory brick no Kilns, kapuahi

E like me nā ʻāpana like ʻole o nā ʻāpana refractory, hiki ke hoʻokaʻawale ʻia lākou i ʻelima mau ʻāpana, ʻo ia hoʻi: silicon-alumina series refractory bricks, alkaline series refractory bricks, carbon-containing refractory bricks, zirconium-containing refractory bricks, a me ka wela-insulating refractory bricks.

ʻAʻole i kūkulu ʻia kekahi umu ahi me hoʻokahi wale nō ʻano o nā pōhaku refractory, pono ia i ka hui pū ʻana o nā pōhaku refractory like ʻole.

(1) ʻO nā pōhaku silika e pili ana i nā brick refractory i loaʻa ma mua o 93% SiO2, ʻo ia nā ʻano nui o nā pōhaku refractory acid.Hoʻohana nui ʻia ia no nā umu coke masonry, akā no nā waihona a me nā ʻāpana ukana ʻē aʻe o nā kiln wela o nā aniani like ʻole, nā seramika, nā calciners kalapona, a me nā brick refractory.Hoʻohana ʻia ia i nā mea wela ma lalo o 600 ° C a me nā loli wela nui.

(2) Nā pōhaku lepo.ʻO nā pōhaku lepo lepo ka nui o ka mullite (25% a 50%), ka māhele aniani (25% a 60%), a me ka cristobalite a me ka quartz (a hiki i 30%).ʻO ka maʻamau, hoʻohana ʻia ka pālolo paʻakikī e like me ka mea maka, hoʻokaʻawale ʻia ka clinker ma mua a laila hui pū ʻia me ka pālolo palupalu.Hiki ke hoʻohui ʻia kahi kīʻaha wai liʻiliʻi, sima, a me nā mea paʻa ʻē aʻe e hana i nā huahana i puhi ʻole ʻia a me nā mea hana ʻole.He brick refractory maʻamau i hoʻohana ʻia i loko o nā umu ahi, nā kapuahi wela wela, nā kapuahi hoʻomehana, nā paila mana, nā kiln lime, nā kiln rotary, nā seramika, a me nā kiln puhi ahi.
(3) High-alumina refractory bricks.ʻO ka hui ʻana o ka mineral o nā pōhaku kiʻekiʻe-alumina refractory he corundum, mullite, a me nā ʻāpana aniani.ʻO nā mea maka he kiʻekiʻe-alumina bauxite a me ka sillimanite natural ore, a aia pū kekahi corundum fused, alumina sintered, mullite synthetic, a me clinker calcined me ka alumina a me ka pālolo ma nā ʻano like ʻole.Hana ʻia ia ma ke ʻano sintering.Akā ʻo nā huahana pū kekahi me nā pōhaku i hoʻolei ʻia, nā pōhaku i hoʻokuʻu ʻia, nā pōhaku i puhi ʻole ʻia, a me nā pōhaku ʻaʻa ʻole.Hoʻohana nui ʻia nā pōhaku kiʻekiʻe alumina refractory i ka ʻoihana hao a me ke kila, ʻoihana metala non-ferrous, a me nā ʻoihana ʻē aʻe.(4) ʻO nā pōhaku lepo corundum, nā pōhaku corundum e pili ana i keʻano o nā pōhaku lepo me ka AL2O3 maʻiʻo o ka emiʻole ma lalo o 90% a me ka corundum ma keʻano nui, hiki ke hoʻokaʻawaleʻia i nā pōhaku lepo corundum sintered a me nā pōhaku lepo corundum fused (5) High- alumina heat-insulating light-weight refractory bricks.He insulating kukui refractory brick me ka bauxite e like me ka mea nui AL2O3 maʻiʻo o ka emi ʻole ma mua o 48%.Hoʻohana ke kaʻina hana i ke ʻano o ka foam, a hiki ke hoʻohana ʻia ke ʻano hoʻohui ahi.Hiki ke hoʻohana ʻia nā pōhaku lepo māmā me ka alumina kiʻekiʻe no ke kūkulu ʻana i nā papa wela a me nā wahi kahi i ʻole ikaika ai ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana.Ke hoʻopili pololei ʻia me ka lapalapa, ʻaʻole ʻoi aku ka kiʻekiʻe o ka wela o ka ʻili o nā pōhaku kiʻekiʻe alumina wela-insulating refractory ma mua o 1350 ℃.Hiki ke hoʻopili pololei i nā pōhaku lepo hoʻoheheʻe wela ʻo Mullite i ka lapalapa a loaʻa iā ia nā hiʻohiʻona o ke kūpaʻa wela kiʻekiʻe, ikaika kiʻekiʻe, a me ka hopena hoʻopakele ikehu.He mea kūpono ia no ka uhi ʻana o ka umu pyrolysis, ka umu wela wela, ka kiln wili seramika, ka kiln porcelain drawer, a me nā umu kū'ē like ʻole.(6) Palolo wela-insulating lightweight refractory bricks he wela-insulating refractory brick me AL2O3 maʻiʻo o 30% a 48% i hana ʻia me ka pālolo refractory ma ke ʻano he kumu kumu.Hoʻohana ʻia kāna kaʻina hana i ke ʻano burn-out plus character a me ke ʻano o ka foam.Me ka hoʻohana ʻana i ka pālolo refractory, nā pahu lana, a me ka clinker palolo refractory e like me nā mea maka, e hoʻohui ana i ka binder a me ka sawdust, ma o ka hui ʻana, ka hui ʻana, ka hoʻoheheʻe ʻana, ka maloʻo ʻana, a me ke kī ʻana, loaʻa ka huahana me ka nui nui o 0.3 a 1.5g/cm3.ʻO ka hoʻopukaʻana o nā pōhaku lepo wela-insulating no ka hapa nui o ka nui o ka hoʻopukaʻana o nā pōhaku lepo pale wela.
