ʻO nā pōhaku silika carbide ke ʻano o nā mea kūkulu hale refractory koʻikoʻi no nā kapuahi like ʻole a me nā kiln i ke kiʻekiʻe kiʻekiʻe a me ka ikaika kiʻekiʻe erosion ea. He hana maikaʻi loa ʻo Silicon carbide refractory brick i ke kūʻē ʻana i ka ʻinoʻino o ke kaiapuni, e like me ka conductivity wela kiʻekiʻe, ke kūpaʻa abrasive maikaʻi, ke kūpaʻa haʻalulu nui, ke kūpaʻa ikaika i ka waikawa a me ka alkali slag erosion a me ka hoʻonui haʻahaʻa wela. Hoʻohana nui ʻia ka refractory silicon carbide castable no nā ʻāpana like ʻole o ka kiln sima a me ka hale o ka umu ahi arc a me ka ladel kila.
Hana ʻia ʻo Silicon carbide brick i ka SiC ʻeleʻele maka. ʻO ka māhele kristal nui ʻo SiC. Hoʻokumu ʻia ʻo Refractory silicon carbide brick ma ka hoʻohālikelike ʻana i ka mea hoʻopaʻa paʻa, ka hui ʻana, ka hana ʻana a me ke kaʻina hana. ʻO ka paʻakikī o ka moth carbide brick he 9, no laila, ʻoi aku ka ikaika o ka pale ʻana o ka carbide Silicon insulation.
ʻO nā mea maka o ka silika carbide bricks he silicon carbide, ma kahi o 72% -99%. Kapa ʻia ʻo Silicon carbide ka moissanite, ke one corundum a i ʻole ke one refractory. Hana ʻia ʻo Silicon carbide refractory brick e ke one quartz, petroleum coke a i ʻole ka lanahu, a me nā ʻāpana lāʻau, i hana ʻia e ka hoʻoheheʻe ʻana i ka wela i ka umu hoʻoheheʻe uila.
Hiki ke hoʻokaʻawale ʻia nā pōhaku lepo silicon carbide refractory i loko o ka pālolo i hoʻopaʻa ʻia i nā pōhaku silikon carbide, Si3N4 i hoʻopaʻa ʻia i nā pōhaku silika carbide, Sialon i hoʻopaʻa ʻia i nā pōhaku silika carbide, β-SiC i hoʻopaʻa ʻia i nā pōhaku silikon carbide, Si2ON2 i hoʻopaʻa ʻia i nā pōhaku silikon carbide a me nā pōhaku lepo kalikikona carbide recrystal.

Hoʻohana nui ʻia ka refractory silicon carbide castable no nā ʻāpana like ʻole o ka kiln sima a me ka hale o ka umu ahi arc a me ka ladel kila. A hiki ke hoʻohana ʻia ma nā wahi aʻe.
ʻO ka hale hana refractory RS ma ke ʻano he mea hana silicon carbide castable ma Kina, he nui nā pono hoʻokūkū ma ka mākeke. inā loaʻa iā ʻoe ke koi o ka silicon carbide castable, a i ʻole he mau nīnau e pili ana i ka silicon carbide refractory castable e pili ana i nā hōʻailona kino a me nā kemika, e ʻoluʻolu e kelepona mai iā mākou no ka manuahi, e hāʻawi mākou iā ʻoe i nā kiʻi kiʻekiʻe silicon carbide castables.
