Ukukhetha okufanelekileyoizitena zekhabhoni ze-magnesiumkwii-oven zemizi-mveliso kunye nee-oven ezishushu kakhulu zimisela ngokuthe ngqo ubomi benkonzo ye-oven, uzinzo lokusebenza, kunye nokusebenza kakuhle kweendleko zemveliso iyonke. Abaqhubi beefektri abaninzi bahlala behlangabezana neengxaki ezifana nokuxobuka kwezitena, ukukhukuliseka okukhulu kwe-slag, kunye nomonakalo wangaphambi kwexesha kwizinto ezingafunekiyo. Isizathu esisisiseko kukuba bayasilela ukudibanisa iimeko zokusebenza ze-oven xa bekhetha izitena ze-carbon ze-magnesia kwaye bayayityeshela imilinganiselo ephambili ye-oven.
Okokuqala, fanisa umgangatho wezitena ngokweqondo lobushushu lokusebenza oluqhubekayo lwe-oven. Kwii-oven ze-metallurgical ezinomthwalo ophezulu kunye nee-oven ezijikelezayo ezisebenza ngokuzinzileyo ngaphezulu kwe-1700°C ixesha elide, kuyimfuneko ukukhetha izitena ze-magnesia carbon ezixutywe ngobumsulwa obuphezulu ezinomxholo we-MgO ongaphezulu kwe-97% kunye neefomyula ezichasene ne-oxidant ezilungiselelweyo. Ezi zitena zinokubonelela ngamandla azinzileyo obushushu obuphezulu kwaye ziphephe ukuthamba kunye nokuguquka phantsi kobushushu obuphezulu obugqithisileyo bexesha elide. Kwii-oven eziphakathi nezisezantsi ezihlala zivaliwe rhoqo kunye nemijikelo yokuguquguquka kobushushu, izitena ze-magnesia carbon zezinga eliphakathi ezinokumelana nobushushu obulinganiselayo zanele, ezinokunciphisa ngempumelelo iindleko zokuthenga ezingeyomfuneko.
Okwesibini, gxila kubunzulu bokukhukuliseka kwe-slag kunye nemeko-bume yomoya ngaphakathi kwi-oven. Kwiindawo ze-oven ezidibana ne-slag eqinileyo ye-alkaline enyibilikisiweyo (ezifana nemigca ye-ladle slag kunye ne-melting zone linings), kufuneka kukhethwe izitena ze-magnesia carbon ezine-high-density kunye ne-low-porosity ukuze kuthintelwe ukungena kwe-slag kwaye kuthintelwe ukukhukuliseka kweekhemikhali. Kwiindawo ze-oven ezinomxholo ophezulu we-oksijini kwaye zisengozini yokubola kwe-carbon, kufuneka kukhethwe izitena ze-magnesia carbon ezidityanisiweyo ezongezwe nge-anti-oxidants ezikumgangatho ophezulu ukuze kuncitshiswe ukulahleka kwe-carbon kunye nokugcina ingqibelelo yesakhiwo sexesha elide se-refractory lining.
Okwesithathu, cinga ngoxinzelelo loomatshini kunye nemijikelo yobushushu rhoqo kwiindawo eziphambili ze-oven. Kwiindawo ezinefuthe, ii-tops ze-oven, kunye neendawo ezine-cold-heat switching rhoqo, kufuneka kukhethwe izitena ze-magnesia carbon ezisemgangathweni ezinomxholo we-carbon ofanelekileyo ukuphucula ukumelana nobushushu kunye nokusebenza kokulwa nokukrazula, ukuthintela ngempumelelo ukuqhekeka kunye nokuchitheka ngokubanzi kwe-oven lining ngexesha lokusebenza kwe-oven yemihla ngemihla.
Ukukhetha okuthembekileyo kwezitena zekhabhoni ze-magnesia akupheleli nje ekulandeleni ngokungakhathali ukubekwa kweenkcukacha eziphezulu, kodwa malunga nokuhambelana okujoliswe kuko ngokweqondo lobushushu, iimpawu ze-slag, umjikelo wokusebenza kunye nomthwalo woomatshini we-oven yakho. Izisombululo zethu zezitena zekhabhoni ze-magnesia ezenzelwe wena ezipheleleyo zifanelekile kwiintlobo ezahlukeneyo zee-oven zoshishino, zibonelela ngovavanyo lweparamitha yemeko yokusebenza yasimahla kunye nesikhokelo sokukhetha ubuchwephesha somntu ngamnye, zinceda iifektri ukuba zandise ubomi benkonzo yee-linings ze-oven ngama-30% kwaye zinciphise ukulahleka okupheleleyo kwezinto ezingafunekiyo. Ukuba ufuna isicwangciso sokukhetha esikhethekileyo kunye nesicatshulwa esichanekileyo, nceda uzive ukhululekile ukubuza. Siza kuphendula ngokukhawuleza ukukunika iimveliso zezitena zekhabhoni ze-magnesia ezingabizi kakhulu kunye nenkxaso yobuchwephesha yobuchwephesha, kwaye sisebenzisane ukunciphisa iindleko zakho zemveliso kunye nokusebenza.
