Ishishini lentsimbi limi njengomqolo weziseko zophuhliso zehlabathi, kodwa lisebenza kwenye yezona ndawo zishushu kakhulu eMhlabeni. Ukususela kubushushu obukhulu bokunyibilikisa isinyithi ukuya ekuchanekeni kokwenziwa kwesinyithi, izixhobo ezibalulekileyo ezifana nee-converters, ii-electrical arc furnitures, kunye nee-blast furnitures zijongene noxinzelelo olungapheliyo: kufuneka zinyamezele ukuvezwa rhoqo kumaqondo obushushu adla ngokudlula i-1,600°C, adibene nokukhukuliseka okunamandla okuvela kwi-slag enyibilikisiweyo kunye nentsimbi etshayo. Ezi meko zimbi zibeka iimfuno ezingenakuthelekiswa nanto kwizinto ezichaseneyo—iileya zokukhusela ezikhusela izixhobo ekonakaleni—naphakathi kwazo zonke iindlela,izitena ze-magnesium-chromiumkuvela njengesisombululo esiphezulu nesithembekileyo.
Izitena zeMagnesium-chromium zinendawo yazo engenakuthelekiswa nanto kwishishini lentsimbi ngenxa yeempawu ezintathu eziphambili, ezingenakoyiswa ezijongana nayo yonke indawo enzima yokuveliswa kwentsimbi eshushu kakhulu. Okokuqala, ukumelana kwazo nomlilo okugqwesileyo kutshintsha umdlalo wokhuseleko nokusebenza kakuhle: ngomgangatho wokuchasana okungaphezulu kakhulu kwe-1,700°C, ezi zitena zigcina ulungelelwaniso lwazo lwesakhiwo nakwiindawo ezishushu kakhulu zezitofu zokwenza intsimbi. Ngokungafaniyo nezinto ezichasana nokuchasana ezinokuthi zithambe okanye zinyibilike phantsi kobushushu obugqithisileyo, izitena zeMagnesium-chromium zisusa umngcipheko wokusilela kwezixhobo ngequbuliso, okunokumisa imigca yemveliso kwaye kukhokelele ekulibazisekeni okubizayo. Okwesibini, ukumelana kwazo okuphezulu kwe-slag kujongana ngokuthe ngqo nomnye wemingeni emikhulu yokugcinwa kweshishini lentsimbi. Zenziwe yiMagnesium oxide kunye neChromium oxide ecocekileyo kakhulu, izitena zenza umqobo oxineneyo, ongenakungena ogxotha zombini i-alkaline kunye ne-acidic slags - iimveliso eziqhelekileyo zemveliso yentsimbi ezitya ii-linings eziqhelekileyo. Olu xhathiso lwandisa kakhulu ubomi be-lining yesithando nge-30% nangaphezulu xa kuthelekiswa ne-refractories eqhelekileyo, zinciphisa iindleko zokutshintshwa rhoqo kwaye zinciphise ixesha lokungasebenzi elingalindelekanga. Okwesithathu, ukuzinza kwazo okugqwesileyo kobushushu kuqinisekisa ukuhambelana ngexesha lezigaba ezibalulekileyo zokusebenza. Xa izitofu ziqala okanye zicima, amaqondo obushushu anokutshintsha ngamakhulu eedigri kwixesha elifutshane—uxinzelelo olubangela ukuba uninzi lwezitena luqhekeke okanye luqhekeke. Nangona kunjalo, izitena zeMagnesium-chromium ziyazifunxa ezi nguqu ngokulula, zigcina ii-linings ziqinile kwaye imveliso isebenza kakuhle ngaphandle kokuphazamiseka.
Ezi mpawu zibalaseleyo zenza izitena ze-magnesium-chromium zibe yinto ebalulekileyo kuzo zonke izigaba ezibalulekileyo zokwenza intsimbi, ukusuka ekucutshungulweni kwezinto eziluhlaza ukuya ekubunjweni kokugqibela. Kwii-converters kunye nee-arc furnaces zombane, apho intsimbi inyibilikiswa kwaye icociwe, izitena zijikeleza iindonga zangaphakathi, zinyamezela ukukhuhla ngqo kwintsimbi enyibilikisiweyo kunye ne-slag ebolayo. Olu khuseleko luvumela ii-furnaces ukuba zisebenze kakuhle ixesha elide, zinyusa imveliso yentsimbi yemihla ngemihla. Kwiiladles—iinqanawa ezinkulu ezithutha intsimbi enyibilikisiweyo ukusuka kwii-furnaces ukuya kwiimashini zokufaka—izitena ze-magnesium-chromium zisebenza njenge-liner eqinileyo. Zithintela ukulahleka kobushushu okuya kuphazamisa umgangatho wentsimbi kwaye kuthintele ukuvuza okunokwenzeka, ukuqinisekisa ukuba isinyithi esinyibilikisiweyo sifikelela kwinqanaba laso elilandelayo kwimeko efanelekileyo yokucubungula ngezantsi njengokuqengqeleka okanye ukubumba. Kwanakwii-furnaces eziqhumayo, intliziyo yemveliso yentsimbi, ezi zitena zikhusela iindawo eziphezulu nezisezantsi ezibalulekileyo ekuhlaselweni okudibeneyo kwegesi enobushushu obuphezulu (ukuya kuthi ga kwi-2,000°C) kunye ne-slag enyibilikisiweyo, zigcina ukusebenza okuzinzileyo kwexesha elide okubalulekileyo ekunikezelweni kwentsimbi rhoqo.
Kubavelisi bentsimbi abazama ukunyusa imveliso, ukunciphisa iindleko zokusebenza, kunye nokugcina umgangatho wokhuphiswano, ukukhetha izitena ze-magnesium-chromium ezikumgangatho ophezulu akuyonto ilula nje—yinto efunekayo. Izitena zethu ze-magnesium-chromium zenziwe ngolawulo oluqinileyo lomgangatho, kusetyenziswa izinto eziluhlaza zeprimiyamu ezivavanywa ngokungqongqo ukuhlangabezana nemigangatho yeshishini lehlabathi. Sithembeke zizityalo zentsimbi eziphambili kulo lonke elaseAsia, eYurophu, naseMntla Melika, iimveliso zethu zinerekhodi eqinisekisiweyo yokubonelela ngokusebenza okuzinzileyo, nokuba zikwimeko enzima kakhulu yemveliso. Sebenza nathi namhlanje, kwaye uvumele isisombululo sethu esikhokelayo sokumelana nomlilo kushishino someleze inkqubo yakho yokwenza intsimbi, sinciphise ixesha lokungasebenzi, kwaye sikuncede ufezekise ukukhula okuzinzileyo, kwexesha elide.
