Munzvimbo dzekushanda kwemaindasitiri anopisa zvakanyanya, kudiwa kwezvinhu zvinogara kwenguva refu, zvisingapise kupisa hakugone kutaurwa. Kubva kumaovheni ekugadzira simbi kusvika kumaovheni esimende, michina inobatwa nekupisa kwakanyanya, kuparadzwa kwemakemikari, uye kusakara kwemakanika zvinoda dziviriro yakavimbika kuti ive nechokwadi chekuti mashandiro anoshanda zvakanaka uye anogara kwenguva refu. Apa ndipo panodiwa zvinhu zvinogara kwenguva refu.inogona kukandirwa necorunduminoonekwa sechinhu chinoshandura mutambo, ichipa mashandiro asina muganho anosangana nezvinodiwa zveindasitiri zvakanyanya.
Corundum castable chinhu chinorasika chinoumbwa zvakanyanya ne corundum (aluminium oxide, Al₂O₃) sechikamu uye matrix, pamwe chete nezvinobatanidza zvemhando yepamusoro uye zvinowedzerwa. Hunhu hwayo hwakasiyana hunobva muhunhu hwe corundum, iyo ine nzvimbo yekunyunguduka inodarika 2000°C, kugadzikana kwakanyanya kwekupisa, uye simba repamusoro remakanika. Kusiyana nezvinhu zvechinyakare zvinorasika, corundum castable inopa musanganiswa wakasiyana wekushanduka uye kugara kwenguva refu—hunhu hwayo hwekudurura hunoita kuti ive nyore kuisa muzvimiro zvakaoma, nepo chimiro chayo chakakora chinodzivirira kupwanyika, kukweshwa, uye kurwiswa nemakemikari kubva kumarara, acids, uye alkalis.
Chimwe chezvakanakira zvikuru zve corundum castable ndechekuti inoshanda zvakasiyana-siyana mumaindasitiri. Muindasitiri yesimbi, inoshandiswa zvakanyanya muma ladles, tundishes, uye blast furnace linings, uko inotsungirira tembiricha yesimbi yakanyungudutswa uye maitiro ekupisa akasimba. Vagadziri vesimbi vanovimba ne corundum castable kuderedza nguva yekushanda inokonzerwa nekutadza kwezvinhu, sezvo hupenyu hwayo hurefu hwebasa huchireva kuti inogadzirisa zvishoma uye mitengo yakaderera yekushanda. Kune indasitiri yesimende, corundum castable inoshandiswa munzvimbo dzekuchinja kwe simende muchoto uye muma tertiary air ducts, inogara tembiricha yakakwira uye abrasive cement clinker. Kusagona kwayo kupisa kunoita kuti zvinhu zvirambe zviripo kunyangwe panguva yekuchinja-chinja kwetembiricha, dambudziko rinowanzoitika mukugadzirwa kwesimende.
Kupfuura simbi nesimende, corundum castable inobudirira mukugadzira simbi dzisina ferrous, kugadzira magirazi, uye mafekitori ekupisa marara. Mukugadzira simbi dzisina ferrous (semuenzaniso, mhangura, aruminiyamu), inodzivirira ngura kubva kusimbi dzakanyungudutswa uye fluxes, ichidzivirira michina yakakosha senge maovheni ekunyungudutsa nezvitofu. Mafekitori egirazi anoshandisa corundum castable muma regenerator nema ports efurnace, uko inochengetedza hunhu hwayo pasi pekupisa kwakanyanya uye makemikari kubva mukunyunguduka kwegirazi. Mafekitori ekupisa marara anobatsirwa nekusadzivirira kwayo magasi ane chepfu uye kupwanywa kwedota, zvichiwedzera hupenyu hwema linings eincinerator uye kuderedza njodzi dzezvakatipoteredza.
Chimwe chinhu chinokwezva che corundum castable ndechekugona kwayo kuchinjika. Vagadziri vanogona kugadzirisa kuumbwa kwe corundum (semuenzaniso, corundum chena, corundum yebrown, tabular corundum) uye zvimwe zvinowedzerwa kuti zvienderane nezvinodiwa zvekushandisa. Semuenzaniso, high-alumina corundum castable (Al₂O₃ content ≥ 90%) inopa kusimba kwakanyanya pakupisa kwenzvimbo dzine tembiricha yakakwira, nepo mafomura esimende yakaderera kana ultra-low-cement achivandudza huwandu uye anoderedza porosity, zvichideredza kupinda kwetsvina. Pamusoro pezvo, sarudzo dzakareruka dze corundum castable dzinopa insulation yekupisa pasina kukanganisa simba remakanika, dzakanakira magadzirirwo emaindasitiri anochengetedza simba.
Pakusarudza corundum castable, zvakakosha kushanda pamwe chete nemutengesi ane mukurumbira anotevedzera mitemo yepasi rose yemhando yepamusoro (semuenzaniso, ISO, ASTM). Corundum castable yemhando yepamusoro inodzorwa zvakanyanya, ichivimbisa kushanda zvakanaka, kuumbwa kwemakemikari kwakasimba, uye hunhu hwakavimbika hwekuisa. Vatengesi vane hunyanzvi hwehunyanzvi vanogonawo kupa rutsigiro panzvimbo, kusanganisira nhungamiro yekusarudza zvinhu, mirairo yekusanganisa, uye mazano ekugadzirisa mushure mekuiswa, zvichiwedzera kukosha kwemari yako.
Munzvimbo yemazuva ano yekukwikwidzana kwemaindasitiri, kuderedza nguva yekushanda, kuderedza mari yekugadzirisa, uye kuvandudza kushanda zvakanaka kwemotokari ndizvo zvinonyanya kukosheswa. Corundum castable inoshanda pamativi ese, ichipa mhinduro inodhura uye inogara kwenguva refu yekushandisa pakupisa kwakanyanya. Inodzivirira kupisa zvakanyanya, inodzivirira ngura, uye inogona kushandiswa pakuita zvinhu zvakasiyana-siyana zvinoita kuti ive chinhu chinosarudzwa nemaindasitiri ari kutsvaga kuwedzera kugona uye kuvimbika.
Ungave uchishandisa chigayo chesimbi, fekitori yesimende, fekitori yegirazi, kana nzvimbo yekupisa marara, corundum castable inogona kushandura mashandiro ako ekupisa kwakanyanya. Isa mari mu corundum castable yemhando yepamusoro nhasi uye ona mutsauko mukushanda kwemidziyo, kugara kwenguva refu, uye mhedzisiro yakanaka. Bata timu yedu yenyanzvi dzinoramba kushanda kuti udzidze zvakawanda nezvemhinduro dzedu dzakagadzirirwa corundum castable uye tora danho rekutanga rekuvandudza mashandiro ako eindasitiri.
