Kwishishini le-steelmaking, i-ladle yensimbi iyisitya esibalulekileyo esithwala, sibambe, kwaye siphathe intsimbi etyhidiweyo phakathi kweenkqubo ezahlukeneyo zokuvelisa. Ukusebenza kwayo kuchaphazela ngokuthe ngqo umgangatho wentsimbi, ukusebenza kakuhle kwemveliso, kunye neendleko zokusebenza. Nangona kunjalo, isinyithi esinyibilikisiweyo sifikelela kumaqondo okushisa aphezulu kwi-1,600 ° C okanye ngaphezulu, kwaye iphinda idibanise ne-slags enobudlova, ukukhukuliseka komatshini, kunye nokutshatyalaliswa kwe-thermal-ibeka imingeni enzima kwizinto eziphikisayo ezibeka i-ladle yensimbi. Kulaphoizitena zekhabhoni ye-magnesium(Izitena ze-MgO-C) zivelele njengesisombululo esona siphumo, sinikezela ukuqina okungenakulinganiswa kunye nokuthembeka kwimisebenzi ye-ladle yensimbi.
Kutheni izitena zeMagnesium Carbon ziyimfuneko kwiiLadles zentsimbi
Iileyile zensimbi zifuna izinto eziphikisayo ezinokumelana neemeko ezinzima ngaphandle kokunciphisa ukusebenza. Izitena zemveli ezilahlayo zihlala zisilela ukuhlangabezana nezi mfuno, ezikhokelela ekutshintshweni rhoqo, ukwehla kwexesha lokuvelisa, kunye neendleko ezongeziweyo. Izitena zekhabhoni ye-Magnesium, nangona kunjalo, zidibanisa amandla e-high-purity magnesia (MgO) kunye negraphite ukujongana nayo yonke imingeni ephambili ye-steel ladle lining:
1. Ukumelana nobushushu obubalaseleyo
I-Magnesia, icandelo eliphambili lezitena ze-MgO-C, ine-ultra-high melting point malunga ne-2,800 ° C-edlula kakhulu ubushushu obuphezulu bensimbi etyhidiweyo. Xa idityaniswe negraphite (izinto eziphathekayo ezinozinzo oluhle kakhulu lwe-thermal), izitena zekhabhoni ye-magnesium zigcina ingqibelelo yazo yesakhiwo naphantsi kokuvezwa kwexesha elide kwi-1,600 + ° C yensimbi etyhidiweyo. Oku kuxhathisa kuthintela ukuthamba kwezitena, ukuguqulwa, okanye ukunyibilika, ukuqinisekisa ukuba i-ladle yensimbi ihlala ikhuselekile kwaye isebenza ixesha elide.
2. Ukumelana ne-Superior Slag Corrosion
Intsimbi enyibilikisiweyo ihamba kunye ne-slags-byproducts ecebileyo kwii-oxides (ezifana ne-SiO₂, i-Al₂O₃, kunye ne-FeO) ezonakalisa kakhulu kwi-refractories. I-Magnesia kwizitena ze-MgO-C isabela kancinane ngezi slags, yenze umaleko oshinyeneyo, onganyanyekiyo kumphezulu wezitena othintela ukungena ngakumbi kwe-slag. Ngokungafaniyo nezitena ze-alumina-silica, ezikhukuliseka ngokulula zizitena ezineasidi okanye ezisisiseko, izitena zekhabhoni yemagnesium zigcina ubungqingqwa bazo, zinciphisa umngcipheko wokuvuza kweladle.
3. Okugqwesileyo kweThermal Shock Resistance
Iileyile zentsimbi zifudumeza ngokuphindaphindiweyo (ukubamba intsimbi etyhidiweyo) kunye nokupholisa (ngexesha lokugcinwa okanye ukungenzi nto)—inkqubo ebangela ukothuka kwe-thermal. Ukuba izinto eziphikisayo azikwazi ukumelana nokutshintsha kweqondo lokushisa ngokukhawuleza, ziya kuqhekeka, zikhokelela ekungaphumeleli kwangaphambi kwexesha. Igraphite kwizitena zekhabhoni ye-magnesium isebenza njenge "buffer," ifunxa uxinzelelo lwe-thermal kunye nokuthintela ukwakheka kokuqhekeka. Oku kuthetha ukuba izitena ze-MgO-C zinokunyamezela amakhulu emijikelezo yokufudumeza-ukupholisa ngaphandle kokulahlekelwa ngumsebenzi, ukwandisa ubomi benkonzo ye-ladle yensimbi yensimbi.
4. Iindleko eziNcitshisiweyo zokunxiba kunye nokuLondoloza
Ukunxitywa komatshini ukusuka kwintsimbi etyhidiweyo eshukumisayo, ukunyakaza kweladle, kunye nokukhuhla kwe-slag ngomnye umba ophambili kwiirefractories zentsimbi. Izitena zekhabhoni ye-Magnesium zinamandla amakhulu omatshini kunye nokuqina, ngenxa yokudibanisa phakathi kweenkozo ze-magnesia kunye negraphite. Oku kuqina kunciphisa ukunxiba kwezitena, okuvumela i-ladle ukuba isebenze ixesha elide phakathi kwe-relinings. Kwizityalo zentsimbi, oku kuguqulela kwixesha elincinane lokuphumla, iindleko eziphantsi zabasebenzi zokutshintshwa kwe-refractory, kunye neeshedyuli zemveliso ezingaguqukiyo.
Usetyenziso oluphambili lwezitena zeMagnesium Carbon kwiiLadles zentsimbi
Izitena zekhabhoni ze-Magnesium azikho isisombululo esisodwa-zilungelelaniswe kwiindawo ezahlukeneyo zentsimbi yensimbi ngokusekelwe kumanqanaba athile oxinzelelo:
Ladle Phantsi kunye neendonga:Iindonga ezisezantsi kunye nezisezantsi ze-ladle zihambelana ngokuthe ngqo, ixesha elide lokuqhagamshelana nentsimbi etyhidiweyo kunye ne-slags. Apha, izitena zekhabhoni ezixineneyo ze-magnesium (ezine-10-20% yomxholo wegraphite) zisetyenziselwa ukuxhathisa ukubola kunye nokunxiba.
Ladle Slag Line:Umgca we-slag yeyona ndawo isengozini kakhulu, njengoko ijongene nokuvezwa ngokuqhubekayo kwi-slags e-corrosive kunye ne-thermal shock. Izitena eziphambili zekhabhoni yemagnesium (ezinomxholo ophezulu wegraphite kunye ne-antioxidants ezongeziweyo ezifana ne-Al okanye i-Si) zibekwe apha ukwandisa ubomi benkonzo.
I-Ladle Nozzle kunye nomngxuma weTepa:Ezi ndawo zifuna izitena ezine-conductivity ephezulu ye-thermal kunye nokumelana nokukhukuliseka ukuqinisekisa ukuhamba kwentsimbi etyhidiweyo. Izitena ezikhethekileyo zeMgO-C ezinemagnesia ecolekileyo zisetyenziselwa ukuthintela ukuvaleka kunye nokwandisa ubomi bombhobho.
Iinzuzo kwiZityalo zeNsimbi: Ngaphaya koKuhlala ixesha elide
Ukukhetha izitena zekhabhoni ye-magnesium yentsimbi ye-ladle linings inikezela ngeenzuzo zoshishino ezibonakalayo kubavelisi bentsimbi:
Umgangatho weNsimbi ophuculweyo:Ngokuthintela ukukhukuliseka kwe-refractory, izitena ze-MgO-C zinciphisa umngcipheko wee-particle refractory ezingcolisa insimbi etyhidiweyo-ukuqinisekisa ukubunjwa kweekhemikhali okuhambelanayo kunye neziphene ezimbalwa kwiimveliso zetsimbi ezigqityiweyo.
Ugcino lwamandla:I-high conductivity ye-thermal ye-graphite kwizitena ze-MgO-C inceda ukugcina ukushisa kwi-ladle, ukunciphisa imfuno yokufudumeza kwakhona intsimbi etyhidiweyo. Oku kunciphisa ukusetyenziswa kwamafutha kunye nokukhutshwa kwekhabhoni
Ubomi benkonzo ye-Longer Ladle: Ngokomyinge, i-magnesium carbon linings igcina amaxesha angama-2-3 ubude kuneentsimbi zendabuko ezichasayo. Kwi-ladle yensimbi eqhelekileyo, oku kuthetha ukuxhomekeka kanye kuphela kwiinyanga ezi-6-12, xa kuthelekiswa namaxesha angama-2-3 ngonyaka kunye nezinye izinto.
