I-chromium magnesia ye-chrome yezitena eziphantsi ze-chrome kunye nezitena ezibotshiweyo ze-magnesia chrome

Izitena zeMagnesia chrome ziyimveliso enqabileyo ene-magnesium oxide (MgO) kunye ne-chromium trioxide (Cr2O3) njengezona zinto ziphambili, kunye ne-periclase kunye ne-spinel njengezona zinto ziphambili zezimbiwa. Olu hlobo lwezitena lunokuphinda kuphindwe, amandla obushushu aphezulu, ukuxhathisa okunamandla kukhukuliseko lwe-alkaline slag, uzinzo oluhle kakhulu lwe-thermal, kunye nokulungelelana okuthile kwi-acid slag. Ezona zinto ziphambili zokwenza izitena zemagnesia-chrome yi-sintered magnesia kunye ne-chromite. Ukucoceka kweemagnesia izinto ezingafunekiyo kufanele ukuba kube phezulu kangangoko kunokwenzeka. Iimfuno zokwenziwa kweekhemikhali ze-chromite zezi: Cr2O3: 30 ~ 45%, CaO: ≤1.0 ~ 1.5%.

Izitena zeMagnesium chrome zisetyenziswa ikakhulu kwishishini lokunyibilikisa isinyithi, njengokwakhiwa kweendawo ezivulekileyo zokubasa eziko, iziko lombane, iziko lokucoca ngaphandle kweziko kunye nomlilo owenziwe ngentsimbi. Icandelo lobushushu obuphezulu lodonga lwesithando samandla ombane esenziwe ngombane senziwe ngezitena ezihlanganisiweyo ze-magnesia-chrome, indawo yokukhukuliseka okuphezulu kweziko lokucoca ngaphandle kweziko lenziwe ngezinto zokwenziwa, kwaye Indawo yokukhukuliseka okuphezulu kwesinyithi esinyibilikisayo esenziwe ngesinyithi senziwe ngezitena ezihlanganisiweyo ze-magnesia-chrome kunye nezinto zokwenziwa. Yenziwe ngemagnesia chrome izitena. Ukongeza, i-magnesia-chrome izitena zikwasetyenziswa kwindawo evuthayo yesamente iilensi ezijikelezayo kunye nokuzihlaziya ngokutsha kwee-kilns zeglasi.

Iipropathi ezibonakalayo zomzimba kunye neekhemikhali zezitena ze-chromium magnesia chrome eziphantsi kunye nezitena ze-magnesia eziboshwe ngokuthe ngqo ezisetyenziswe kwiikhonksi zesamente zezi zilandelayo:

Ngokunxulumene nokwakhiwa kunye nokusebenza kwezi ntlobo zimbini zezitena, amashishini ahlukeneyo kunye namanqaku kufuneka anikwe ingqalelo ekusebenziseni kwiziko lesamente.

1. Isitena sesitena

Ngqo zidityaniswe nezitena zemagnesia-chrome ezingaphantsi kwe-1500, utshintsho lomgca lunokufikelela kwi-0.2% -0.8%. Kukho iipleyiti zentsimbi okanye udaka olushenxisayo kwisangqa sezitena ukufunxa oku kwandiswa kwezinto ezidibeneyo, ngoko ke indlela yokwakha ecocekileyo ngaphandle kweepleyiti zentsimbi okanye udaka lomlilo ayinakusetyenziswa. , Kwaye isitena esincinci se-chromium magnesia chrome sibonelelwa ngomqamelo wekhadibhodi, esokugqibela enobunzima bekhadibhodi obungu-2mm

2. Iziko lokubhaka

Izitena eziboshwe ngokuthe ngqo ze-magnesia-chrome zibuthathaka ngakumbi kuxinzelelo lwangaphakathi lwesitena esibangelwe kukufudumeza kunye ne-ellipticity yomzimba weziko, kufuneka ulawulo olungqongqo.
Izitena ze-magnesia-chrome eziqhotyoshelwe ngokuthe ngqo ziqulathe i-chromium eninzi, inokumelana okuphantsi nokubola kwe-alkali kwi-oksijini yomoya, kwaye iibhondi zokubopha isigaba se-chromium zitshatyalalisiwe. Izitena kulula ukuzonakalisa kwaye zibangela ungcoliseko olukhulu kwindalo esingqongileyo.

3. Ukumelana nokunciphisa umoya

Ukuphendula okufanayo kwenzeka kuzo zombini iintlobo zezitena kwindawo yokunciphisa, etshabalalisa isigaba sokudibanisa kwaye ekugqibeleni ikhokelele kumonakalo kwizitena. Ukudityaniswa ngqo kwezitena zemagnesia-chrome kuya kuchaphazeleka kakhulu.

4. Impembelelo ekubunjweni kwesikhumba somlilo

Uluhlu olucekeceke kwi-C4AF luyakwenziwa phakathi kwe-chromium esezantsi kunye nentsimbi ephezulu ye-magnesia-chrome yezitena kunye ne-clinker, ke ukusebenza kwesikhumba somlilo kungcono. Ukusebenza kwesikhumba somlilo kudityaniswe ngqo nezitena zemagnesia-chrome kuyahluka ngokwakhiwa kwezitena. Xa ulusu lomlilo luqhelekile Xa ulwakhiwo kunye nolondolozo lulungile, iqondo lobushushu bomgangatho wezitena phantsi kwesikhumba somlilo wehla kakhulu, kwaye akubalulekanga kakhulu ukudibanisa ngokuthe ngqo izibonelelo zamandla aphezulu obushushu esitena se-magnesia chrome.
Ngoku kuphume isitena esincinci se-chrome magnesia-chrome, isitena esine-chrome-free, amandla emveliso ukuya kuthi ga kwi-6000-10000T / h ye-oyile ye-PC, ubushushu obuphezulu kunye nokuxhathisa kukothuka okufudumeleyo kubaluleke kakhulu, bakhulisa incam ehambelana nayo iSpar kudityaniswe nococeko oluphezulu olungenachromium-free magnesium ubukhulu becala isetyenziswa kakhulu kwindawo yotshintsho yesamente.
