Ishishini lentsimbi limi njengomqolo weziseko ezingundoqo zehlabathi, kodwa lisebenza kwenye yezona ndawo zinzima zobushushu obuphezulu eMhlabeni. Ukususela kubushushu obukhulu bokunyibilika kwentsimbi ukuya ekuchanekeni kokuphosa kwentsimbi, izixhobo ezibalulekileyo ezifana neziguquli, ii-arc zombane, kunye neziqhumiso eziqhumayo zijongene noxinzelelo olungapheliyo: kufuneka zinyamezele ukuvezwa ngokuqhubekayo kumaqondo obushushu ahlala edlula i-1,600 ° C, edityaniswe nokhukuliseko olunamandla olusuka kwi-slag etyhidiweyo kunye ne-scalding steel. Ezi meko zinzima kakhulu zibeka iimfuno ezingenakulinganiswa kwizinto eziphikisayo-imigangatho yokukhusela ekhusela izixhobo emonakalweni-kunye naphakathi kwazo zonke iinketho,izitena ze-magnesium-chromiumivela njengesona sisombululo sigqibeleleyo, sithembekileyo
Izitena ze-Magnesium-chromium zityala isikhundla sazo esingenakulinganiswa kwishishini lensimbi kwizinto ezintathu ezingundoqo, ezingenakunqotshwa ezijongene nazo zonke iintlungu eziphambili zokuvelisa insimbi yokushisa. Okokuqala, ukuchasana nomlilo okungaqhelekanga kukutshintsha umdlalo wokhuseleko kunye nokusebenza kakuhle: kunye ne-refractoriness rating ngaphezu kwe-1,700 ° C, ezi zitena zigcina ingqibelelo yazo yesakhiwo nakwiindawo ezitshisa kakhulu zokutshisa isinyithi. Ngokungafaniyo nezixhobo ezikumgangatho ophantsi ezinokuthi zithambe okanye zinyibilike phantsi kobushushu obugqithisileyo, izitena zemagnesium-chromium zisusa umngcipheko wokusilela kwezixhobo ngequbuliso, ezinokumisa imigca yemveliso kwaye zikhokelele ekulibazisekeni okubizayo. Okwesibini, ukuxhathisa kwabo okuphezulu kwe-slag ngqo kukujongana nemiceli mngeni yokugcinwa kwentsimbi. Idityaniswe nge-high-purity magnesium oxide kunye ne-chromium oxide, izitena zenza umqobo oxineneyo, ongenakuthintelwa ogxotha zombini i-alkaline kunye ne-acidic slags-imveliso eqhelekileyo yemveliso yentsimbi edla i-linings eqhelekileyo. Oku kuxhathisa kwandisa kakhulu ubomi belinen eziko ngama-30% okanye ngaphezulu xa kuthelekiswa nemigangatho yerefractories, ukucutha iindleko zokutshintsha rhoqo kunye nokunciphisa ixesha lokuphumla elingacwangciswanga. Okwesithathu, ukuzinza kwabo okumangalisayo kwe-thermal kuqinisekisa ukuhambelana ngexesha lezigaba zokusebenza ezibalulekileyo. Xa iziko liqala okanye livaliwe, amaqondo obushushu anokuguquguquka ngamakhulu amaqondo ngexesha elifutshane—uxinzelelo olubangela ukuba uninzi lwezitena luqhekeke okanye luchitheke. Izitena zeMagnesium-chromium, nangona kunjalo, zifunxa oku kuguquguquka ngaphandle komgudu, zigcina i-linings yomelele kwaye imveliso ihamba kakuhle ngaphandle kokuphazamiseka.
Ezi zakhiwo zibalaseleyo zenza izitena ze-magnesium-chromium zibe yimfuneko kulo lonke inqanaba eliphambili lokwenza intsimbi, ukusuka ekusetyenzweni kwemathiriyeli ekrwada ukuya ekugalweni kokugqibela. Kwiziguquli kunye nezixhobo zombane ze-arc, apho intsimbi iyancibilika kwaye ihlanjululwe, izitena zihamba ngeendonga zangaphakathi, zinyamezele ukutshatyalaliswa ngokuthe ngqo kwi-churning steel metal and corrosive slag. Olu khuselo luvumela ii-furnaces ukuba zisebenze kwincopho yokuphumelela ixesha elide, ukonyusa imveliso yentsimbi yemihla ngemihla. Kwiileyile—iinqanawa ezinkulu ezithutha intsimbi etyhidiweyo ukusuka kwiziko ukuya koomatshini bokutyhida—izitena zemagnesium-chromium zisebenza njengentambo eyomeleleyo. Zithintela ilahleko yobushushu enokuthi ibeke esichengeni umgangatho wentsimbi kwaye ithintele ukuvuza okunokwenzeka, ukuqinisekisa ukuba isinyithi esinyibilikisiweyo sifikelela kwinqanaba laso elilandelayo sikwimeko egqibeleleyo yokusetyenzwa phantsi komsinga njengokuqengqeleka okanye ukufoja. Nkqu kwiziko eliqhumayo, intliziyo yemveliso yentsimbi, ezi zitena zikhusela iindawo ezibalulekileyo eziphezulu nezisezantsi kuhlaselo oludityanisiweyo lwegesi yobushushu obuphezulu (ukuya kuthi ga kwi-2,000°C) kunye ne-slag etyhidiweyo, egcina umsebenzi wexesha elide, ozinzileyo obalulekileyo ekuboneleleni ngentsimbi ngokuthe rhoqo.
Kubenzi bentsimbi abazama ukunyusa imveliso, ukunciphisa iindleko zokusebenza, kunye nokugcina umda wokukhuphisana, ukukhetha izitena ezikumgangatho ophezulu we-magnesium-chromium akuyona nje inketho-yiyimfuneko. Izitena zethu ze-magnesium-chromium zenziwe ngolawulo olungqongqo lwekhwalithi, zisebenzisa imathiriyeli ekrwada yeprimiyamu evavanywa ngokuqatha ukuhlangabezana nemigangatho yoshishino yehlabathi. Ithenjwe zizityalo zentsimbi ezikhokelayo kulo lonke elase-Asiya, iYurophu, kunye noMntla Melika, iimveliso zethu zinerekhodi eqinisekisiweyo yokuzisa ukusebenza okungaguqukiyo, nakweyona ndawo ifunwa kakhulu yimveliso. Sebenzisana nathi namhlanje, kwaye uvumele isisombululo sethu sokumelana nomlilo siqinise inkqubo yakho yokwenza intsimbi, ukunciphisa ixesha lokuphumla, kwaye sikuncede ufezekise ukukhula okuzinzileyo, ixesha elide.
