No nā mea refractory i hoʻohana ʻia i ka rotary kiln no ka mālama ʻana i nā ʻōpala pōʻino, paʻakikī ke ʻano kemika o ka ʻōpala pōʻino ma muli o kāna mau ʻano like ʻole, no laila ua hoʻoholo ʻia e hoʻopau ʻia ke ʻano kemika o ka ʻōpala pōʻino ma 700-1000 wela i nā kiln rotary, a me ka ʻO ka mea nui o ka hoʻokuʻu kinoea ma hope o ka calcination o ka ʻōpala weliweli he ʻakika iki.
I refractory, refractory castable i acidic kinoea he maikai paʻa, AL2O3 SiO2 ʻōpala rotary kiln mea he maikai corrosion kū'ē a me castable refractory, ke koho refractory mea, aole i ke koho ana o refractory huahana, Fe2O3 maʻiʻo e like me ka mea hiki no ka Fe2O3 FeCL3 reacts me chlorine kinoea, ke kinoea manawa, volatile a overbalance ka refractory brick, ka sima rotary kiln ua maʻamau hoʻohana 'ia i ka corrosion kū'ē o ka nohona kaiapuni huahana Magnesia hao spinel brick, i ka pōʻino'ōpala rotary kiln refractory mea koho 'aʻole kūpono, i ka hazardous. ʻōpala rotary kiln hānai a me ka puka castable, pono e koho haʻahaʻa sima castable, no ka mea, o ka sima CaO a me ka chlorine pane, ke kukuluia'na o ka wai māhele CaC1 e ho'ēmi i ka wela a me ke kiʻekiʻe wela paʻa o ka castable.
I ke koho ʻana i nā mea refractory, pono e hoʻohana i nā mea hoʻoheheʻe ʻino me ke kūpaʻa maikaʻi o ka ʻaʻahu, ke kūpaʻa haʻalulu a me ka pale ʻana i ka corrosion. ʻO ke kaʻina hana o ka ʻōpala rotary kiln e hoʻohana maʻamau i ke kaʻina hana ahi i lalo. Ke komo nei ka ʻōpala pōʻino o ka makani mua mai ka ʻaoʻao hoʻokahi a he pōkole ka lōʻihi o ke kiln (ʻo ka ratio lōʻihi-anawaena he 3-5m wale nō). He maʻalahi ka pane ʻana i loko o ke kiln, ʻo ia hoʻi, ka hopena o ka hoʻoheheʻe ʻana. Ma waena o nā huahana koʻikoʻi o kēia manawa, ʻoi aku ka maikaʻi o ka mullite sic brick, a hiki ke koho ʻia ka mea castable mullite.
