Sechinhu chinodzivirira kushanda kwepamusoro-soro,zvidhinha zvemhando ye "mullite" zvakarerukaZvinofarirwa zvikuru mumaindasitiri epasi rose nekuda kwekudzivirira kwavo kupisa kwakanyanya, kuramba kupisa kwakanyanya, uye hunhu hwavo hwakareruka. Zvakagadzirwa kuti zvisangane nezvinodiwa zvakasimba zvemidziyo inopisa zvakanyanya, zvidhinha izvi hazvingoderedzi kushandiswa kwesimba chete asiwo zvinowedzera hupenyu hwekushanda kwezvitofu zvemaindasitiri, zvichiita kuti zvive sarudzo yakakodzera kumabhizinesi ari kutsvaga kushanda zvakanaka uye budiriro inoenderera mberi.
Zvinodiwa zvezvidhinha zvemullite zvakareruka zvinogadziriswa uye zvinogona kugadziriswa kuti zvienderane nemamiriro akasiyana emaindasitiri. Mhando huru dzinosanganisira JM23, JM25, JM26, JM27, JM28, JM30, uye JM32, ine alumina iri pakati pe40% kusvika 77% uye iron oxide iri pakati pe1.0% (kusvika pa0.5% yemhando dzakachena). Huremu hwadzo hwakawanda huri pakati pe0.55g/cm³ kusvika 1.35g/cm³, uye simba rekupwanya rinotonhora riri pakati pe1.0MPa kusvika 3.5MPa, zvichiita kuti pave nekushanda kwakasimba pasi pemamiriro akasiyana emutoro. Tembiricha yekupatsanura iri pakati pe1260℃ kusvika 1760℃, tembiricha yekutanga yekunyorovesa mutoro iri pakati pe1080℃ kusvika 1570℃, uye mwero wekuchinja kwemutsara unogara uripo mushure mekupisa kwakanyanya uri pakati pe -1.5% kusvika 0.5%. Saizi yakajairika ndeye 230x114x65mm, uye saizi dzakagadzirirwa vatengi dzinowanikwa zvichienderana nezvinodiwa nematombo asina musono.
Kufambiswa kwekupisa kwezvidhinha zvemullite zvakareruka kwakaderera kusvika ku0.18W/(m·K) pa200℃, izvo zvinogona kuderedza kurasikirwa nekupisa uye kuvandudza kushandiswa kwesimba—chinhu chakakosha mukugadzirwa kwemaindasitiri. Zvidhinha izvi zvakagadzirwa nealumina nesilika, zvinoumba chimiro chekristalline chemullite chakagadzikana, chine girazi diki, cristobalite, kana corundum, izvo zvinowedzera zvakanyanya kuramba kwavo kupisa uye kuramba ngura kwemakemikari. Zvinogona kubata zvakananga nemoto, zvichibvisa kudiwa kwekuwedzera insulation layers uye kurerutsa maitiro ekugadzira masonry.
Zvidhinha zvemullite zvidiki zvine mashandisirwo akasiyana-siyana, zvinofukidza simbi, ceramics, girazi, petrochemical nedzimwe indasitiri. Muindasitiri yesimbi, zvinoshandiswa pakuisa mukati mezvitofu zvinopisa, blast furnace bodies nebottoms, uye steel machinery furnace tops, izvo zvisingangogone kuchengetedza tembiricha dzakagadzikana chete asiwo kuderedza kushandiswa kwesimba. Muindasitiri yesimbi, zvinhu zvakanaka zveroller kilns, shuttle kilns, uye drawer kilns, zvichiita kuti kupisa nekutonhodza zviite nekukurumidza uye kuvandudza kushanda zvakanaka kwekugadzira.
Muindasitiri yemagirazi, anoshandiswa pakugadzira magirazi anonyungudutsa furnace uye nzira dzekudyisa, izvo zvinogona kudzivirira kupisa kwakanyanya uye kuparadzwa kwemakemikari kuti chigadzirwa chive nechokwadi chekuti mhando yezvigadzirwa ndeyemhando yepamusoro. Muindasitiri yemapetrochemical, anoshandiswa pakuisa mukati memafurnace anopwanya petroleum, mafurnace ekugadzira ammonia, uye mafurnace ekugadzira gasification emafuta akasara, ayo anogona kutsungirira mamiriro ekushanda akaomarara. Pamusoro pezvo, anoshandiswa zvakanyanya mumafurnace akasiyana-siyana emagetsi, maincinerator, uye michina yekuita mapombi ekupisa akakwirira, zvichipa insulation yakavimbika yekupisa uye rutsigiro rwechimiro.
Zvichienzaniswa nezvidhinha zvechinyakare zvinoramba kushanda, zvidhinha zvemullite zvakareruka zvine zvazvakanakira pachena: kurema kwakaderera kunogona kuderedza huremu hwechoto uye mutoro wechivakwa, kuyerera kwemafuta kwakaderera kunogona kuchengetedza 15%-20% yemafuta, uye kuchena kwakanyanya kunovimbisa kushanda kwakasimba munzvimbo dzakaoma. Ingave iri mamiriro akajairwa kana kuti maitiro akagadzirwa, anogona kusangana nezvinodiwa zvakasiyana-siyana zvemaindasitiri akasiyana. Sarudza zvidhinha zvedu zvemullite zvakareruka zvemhando yepamusoro kuti zvikubatsire kuderedza mari yekushandisa, kuvandudza kushanda zvakanaka kwekugadzira, uye kuwana budiriro yegirini uye inochengetedza nharaunda.
