Kwindawo yokusebenza kwamashishini obushushu obuphezulu, imfuno yezinto ezihlala ixesha elide, ezichasene nobushushu ayinakuxoxisana. Ukusuka kwiziko zokwenza intsimbi ukuya kwiikonti zesamente, izixhobo ezivezwe kumaqondo obushushu agqithisileyo, ukukhukuliseka kweekhemikhali, kunye nokunxitywa koomatshini kufuna ukukhuselwa okuthembekileyo ukuqinisekisa ukusebenza kakuhle kunye nokuphila ixesha elide. Kulaphocorundum castableibalasele njengesixhobo esitshintsha umdlalo, inika umsebenzi ongenakuthelekiswa nanto ohlangabezana neyona migangatho ingqongqo yemizi-mveliso.
I-Corundum castable yimpahla ephikisayo eyenziwe ngokuyinhloko ye-corundum (i-aluminium oxide, i-Al₂O₃) njenge-aggregate kunye ne-matrix, idibaniswe nezibophelelo eziphezulu kunye nezongezo. Iimpawu zayo ezikhethekileyo zivela kwiimpawu zendalo ze-corundum, eziqhayisa indawo yokunyibilika edlula i-2000 ° C, ukuzinza okuhle kakhulu kwe-thermal, kunye namandla aphezulu omatshini. Ngokungafaniyo nezixhobo zemveli ezichasayo, i-corundum castable inika umxube okhethekileyo wokuguquguquka kunye nokuqina-indalo yayo enokuthululwa ivumela ukuba kube lula ukufakwa kwiimo eziyinkimbinkimbi kunye nezakhiwo, ngelixa isakhiwo sayo esixineneyo sichasana nokuhlaselwa kwe-spalling, abrasion, kunye neekhemikhali ezivela kwi-slags, i-acids kunye ne-alkali.
Enye yeenzuzo eziphambili ze-corundum castable kukuguquguquka kwayo kuwo wonke amashishini. Kwishishini lentsimbi, isetyenziswa kakhulu kwiileyile, i-tundishes, kunye ne-blast furnace linings, apho imelana nobushushu bentsimbi enyibilikisiweyo kunye neempendulo ze-slag ezinobundlobongela. Abavelisi bentsimbi baxhomekeke kwi-corundum castable ukunciphisa ixesha lokunciphisa elibangelwa ukungaphumeleli kwezinto eziphathekayo, njengoko ubomi bayo benkonzo ende buguqulela kwimijikelezo embalwa yokugcina kunye neendleko zokusebenza eziphantsi. Kwishishini le-cement, i-corundum castable isetyenziswe kwiindawo zenguqu ze-sement kiln kunye ne-tertiary air ducts, ukunyamezela ukushisa okuphezulu kunye ne-clinker ye-cement abrasive. Ukuchasana kwayo nomothuko we-thermal kuqinisekisa ukuba izinto zihlala zilungile nangexesha lokutshintsha kweqondo lobushushu ngokukhawuleza, umngeni oqhelekileyo kwimveliso yesamente.
Ngaphaya kwentsimbi kunye nesamente, i-corundum enokugalelwa igqwesile kwi-metallurgy engeyiyo i-ferrous, imveliso yeglasi, kunye nezityalo zokutshisa inkunkuma. Kwi-non-ferrous smelting (umzekelo, ubhedu, i-aluminiyam), ixhathisa ukubola kwisinyithi esityhidiweyo kunye nokuguquguquka, ukukhusela izixhobo ezibaluleke kakhulu ezifana neziko lokunyibilikisa kunye neecrucibles. Iifektri zeglasi zisebenzisa i-corundum castable kwi-regenerators kunye ne-furnace port, apho igcina ingqibelelo yesakhiwo phantsi kobushushu obuphezulu obuqhubekayo kunye nokuvezwa kweekhemikhali kwiglasi enyibilikayo. Izityalo zokutshisa inkunkuma zixhamla ekuxhathiseni iigesi ezinetyhefu kunye nokukrazuka kothuthu, ukwandisa ixesha lokuphila kwezibane zokutshisa kunye nokunciphisa umngcipheko wokusingqongileyo.
Olunye uphawu olunyanzelisayo lwe-corundum castable kukusebenza kwayo ngokwezifiso. Abavelisi banokuhlengahlengisa ukubunjwa kwe-corundum (umzekelo, i-corundum emhlophe, i-brown corundum, i-tabular corundum) kunye nezongezo zokulungisa izinto kwiimfuno ezithile zesicelo. Ngokomzekelo, i-high-alumina corundum castable (i-Al₂O₃ umxholo ≥ 90%) inikeza ukunyanzeliswa kokushisa okuphuculweyo kwiindawo eziphakamileyo zokushisa, ngelixa i-samente ephantsi okanye i-ultra-low-cement formulations iphucula ubuninzi kunye nokunciphisa i-porosity, ukunciphisa ukungena kwe-slag. Ukongeza, ukhetho olulula lwe-corundum olunokuxhonywa lubonelela ngokufakelwa kwe-thermal ngaphandle kokubeka esichengeni amandla oomatshini, alungele ugcino lwemizi-mveliso egcina amandla.
Xa ukhetha i-corundum castable, kubalulekile ukusebenzisana nomthengisi othembekileyo obambelela kwimigangatho yemigangatho yamazwe ngamazwe (umz., ISO, ASTM). Umgangatho ophezulu we-corundum castable uphantsi kolawulo olungqongqo lwekhwalithi, ukuqinisekisa ukusebenza okuhambelanayo, ukubunjwa kweekhemikhali ezizinzileyo, kunye neempawu ezithembekileyo zokufakela. Ababoneleli abanobuchwephesha bobugcisa banokunikezela ngenkxaso kwisiza, kubandakanya isikhokelo sokhetho lwemathiriyeli, imiyalelo yokuxuba, kunye neengcebiso zogcino lwasemva kokufakela, ukwandisa ixabiso lotyalo-mali lwakho.
Kwimeko yanamhlanje yokhuphiswano lwemizi-mveliso, ukunciphisa ixesha lokuphumla, ukuthoba iindleko zokugcina, kunye nokuphucula ukusebenza kakuhle zizinto eziphambili eziphambili. I-Corundum castable ihambisa kuzo zonke iinkalo, inikezela ngeendleko ezisebenzayo, isisombululo esihlala ixesha elide kwizicelo eziphezulu zokushisa. Ukuxhathisa ubushushu obukhethekileyo, ukumelana nomhlwa, kunye nokuguquguquka kwezinto kuyenza ibe yeyona nto ikhethwayo kumashishini afuna ukonyusa imveliso kunye nokuthembeka.
Nokuba usebenzisa umatshini wentsimbi, iplanti yesamente, umzi-mveliso weglasi, okanye indawo yokutshisa inkunkuma, i-corundum castable inokuguqula imisebenzi yakho yobushushu obuphezulu. Tyala imali kumgangatho we-corundum enokuphoswa namhlanje kwaye ufumane umahluko ekusebenzeni kwesixhobo, ixesha elide, kunye neziphumo ezisezantsi. Qhagamshelana neqela lethu leengcaphephe ze-refractory ukufunda ngakumbi malunga nezisombululo zethu ezilungelelanisiweyo zecorundum kwaye uthathe inyathelo lokuqala lokuphucula iinkqubo zakho zeshishini.
