Kwimiba yemisebenzi yemizi-mveliso eshushu kakhulu, imfuno yezinto ezihlala ixesha elide nezimelana nobushushu ayinakuxoxiswana ngazo. Ukususela kwiifeni zokwenza intsimbi ukuya kwiifeni zesamente, izixhobo ezivezwa kubushushu obugqithisileyo, ukukhukuliseka kweekhemikhali, kunye nokuguguleka koomatshini kufuna ukhuseleko oluthembekileyo ukuqinisekisa ukusebenza kakuhle kunye nobude bexesha. Kulapho ke aphoi-corundum castableIbonakala njengesixhobo esitshintsha umdlalo, esinika ukusebenza okungenakuthelekiswa nanto okuhlangabezana nemigangatho yemizi-mveliso engqongqo.
I-Corundum castable yinto enokukhanyela eyenziwe ngokuyintloko yi-corundum (i-aluminium oxide, i-Al₂O₃) njenge-aggregate kunye ne-matrix, idityaniswe nezihlanganisi ezikumgangatho ophezulu kunye nezongezo. Iimpawu zayo ezibalaseleyo zivela kwiimpawu ze-corundum, eneqondo lokunyibilika elingaphezulu kwe-2000°C, uzinzo oluhle kakhulu lobushushu, kunye namandla aphezulu oomatshini. Ngokungafaniyo nezixhobo zemveli zokukhanyela, i-corundum castable inika umxube owahlukileyo wokuguquguquka kunye nokuqina—indalo yayo yokugalela ivumela ukufakwa ngokulula kwiimo kunye nezakhiwo ezintsonkothileyo, ngelixa isakhiwo sayo esixineneyo simelana nokuqhekeka, ukukrala, kunye nokuhlaselwa ngamakhemikhali yi-slags, ii-asidi, kunye ne-alkalis.
Enye yeenzuzo eziphambili ze-corundum castable kukuguquguquka kwayo kumashishini. Kwishishini lentsimbi, isetyenziswa kakhulu kwiiladle, ii-tundishes, kunye nee-blast furniture linings, apho imelana nobushushu bentsimbi enyibilikisiweyo kunye neempendulo ze-slag ezinamandla. Abavelisi bentsimbi baxhomekeke kwi-corundum castable ukunciphisa ixesha lokungasebenzi elibangelwa kukusilela kwezinto, njengoko ubomi bayo obude benkonzo buthetha ukuba imijikelo yolondolozo incinci kwaye iindleko zokusebenza ziphantsi. Kwishishini lesamente, i-corundum castable isetyenziswa kwiindawo zotshintsho ze-samente kiln kunye nee-air ducts eziphezulu, ihlala ishushu kakhulu kwaye i-abrasive cement clinker. Ukumelana kwayo noxinzelelo lobushushu kuqinisekisa ukuba izinto zihlala ziqinile nangona kukho ukuguquguquka kobushushu okukhawulezayo, umngeni oqhelekileyo kwimveliso yesamente.
Ngaphaya kwentsimbi nesamente, i-corundum castable igqwesile kwi-metallurgy engenazo iintsimbi, ukwenziwa kweglasi, kunye nezityalo zokutshisa inkunkuma. Kwi-non-ferrous smelting (umz., ubhedu, i-aluminium), iyamelana nokugqwala okuvela kwiintsimbi ezinyibilikisiweyo kunye ne-fluxes, ikhusela izixhobo ezibalulekileyo ezifana nezitofu zokunyibilikisa kunye nee-crucibles. Iifektri zeglasi zisebenzisa i-corundum castable kwi-regenerators kunye ne-furnace ports, apho igcina khona ulwakhiwo phantsi kobushushu obuphezulu obuqhubekayo kunye nokuvezwa kweekhemikhali ezivela kwi-glass melting. Izityalo zokutshisa inkunkuma ziyazuza ekuchaseni kwayo kwiigesi ezinobuthi kunye nokukrala kothuthu, okwandisa ubomi be-incinerator linings kunye nokunciphisa iingozi zokusingqongileyo.
Olunye uphawu olunomtsalane lwe-corundum castable kukusebenza kwayo okunokulungiseka. Abavelisi banokulungisa ukwakheka kwe-corundum (umz., i-corundum emhlophe, i-corundum emdaka, i-tableur corundum) kunye nezongezo ukuze zilungelelaniswe nezinto ezifunekayo. Umzekelo, i-corundum castable ene-alumina ephezulu (umxholo we-Al₂O₃ ≥ 90%) inika ukumelana nobushushu okuphuculweyo kwiindawo ezinobushushu obuphezulu kakhulu, ngelixa iifomyula zesamente ephantsi okanye i-cement ephantsi kakhulu ziphucula uxinano kwaye zinciphisa ukubola, zinciphisa ukungena kwe-slag. Ukongeza, iindlela ze-corundum castable ezilula zibonelela ngobushushu ngaphandle kokubeka emngciphekweni amandla oomatshini, zilungele uyilo lwemizi-mveliso olugcina amandla.
Xa ukhetha i-corundum castable, kubalulekile ukusebenzisana nomthengisi othembekileyo onamathela kwimigangatho yomgangatho wamazwe ngamazwe (umz., i-ISO, i-ASTM). I-corundum castable esemgangathweni ophezulu ilawulwa ngokungqongqo komgangatho, iqinisekisa ukusebenza rhoqo, ukwakheka kweekhemikhali okuzinzileyo, kunye neempawu zokufakelwa ezinokuthenjwa. Ababoneleli abanolwazi lobuchwephesha banokubonelela ngenkxaso kwindawo, kubandakanya isikhokelo sokukhetha izinto, imiyalelo yokuxuba, kunye neengcebiso zokulungisa emva kokufakelwa, nto leyo ekhulisa ixabiso lotyalo-mali lwakho.
Kwimeko yezoshishino yanamhlanje enokhuphiswano, ukunciphisa ixesha lokungasebenzi, ukunciphisa iindleko zokulungisa, kunye nokuphucula ukusebenza kakuhle zezona zinto ziphambili. I-Corundum castable inika zonke izinto, inikezela ngesisombululo esingabizi kakhulu nesihlala ixesha elide kwizicelo zobushushu obuphezulu. Ukumelana kwayo nobushushu okugqwesileyo, ukumelana nokugqwala, kunye nokuguquguquka kwenza ukuba ibe yinto ekhethwayo kumashishini afuna ukuphucula imveliso kunye nokuthembeka.
Nokuba usebenzisa umzi-mveliso wesinyithi, isityalo sesamente, umzi-mveliso weglasi, okanye indawo yokutshisa inkunkuma, i-corundum castable inokutshintsha imisebenzi yakho yobushushu obuphezulu. Tyala imali kwi-corundum castable esemgangathweni namhlanje kwaye ufumane umahluko ekusebenzeni kwezixhobo, ixesha elide, kunye neziphumo ezilungileyo. Nxibelelana neqela lethu leengcali ezichasene nokuchasana ukuze ufunde ngakumbi malunga nezisombululo zethu ze-corundum castable ezenziwe ngokwezifiso kwaye uthathe inyathelo lokuqala lokuphucula iinkqubo zakho zoshishino.
