Izitini eziphansi ze-chromium magnesia chrome zezinsimbi zikasimende kanye nezitini eziqondile ze-magnesia chrome

Izitini ze-chrome zeMagnesia ziyimikhiqizo ekhombayo ene-magnesium oxide (MgO) ne-chromium trioxide (Cr2O3) njengezinto eziyinhloko, ne-periclase ne-spinel njengezinto eziyinhloko zamaminerali. Lolu hlobo lwezitini lunokuphindwa okuphezulu, amandla okushisa aphakeme, ukumelana okuqinile nokuguguleka kwe-alkaline slag, ukuzinza okuhle kakhulu kokushisa, kanye nokuvumelana nezimo okuthile ku-acid slag. Izinto zokusetshenziswa eziyinhloko zokwenza izitini zemagnesia-chrome yi-sintered magnesia ne-chromite. Ukuhlanzeka kwezinto zokusetshenziswa zemagnesia kufanele kube phezulu ngangokunokwenzeka. Izidingo zokwakheka kwamakhemikhali kwe-chromite yilezi: Cr2O3: 30 ~ 45%, CaO: ≤1.0 ~ 1.5%.

Izitini ze-Magnesium chrome zisetshenziswa kakhulu embonini ye-metallurgical, njengokwakhiwa kwamathoshi wesithando somlilo ovulekile, izithando zomlilo kagesi, iziko lokucwenga ngaphandle kwesithando kanye nezinye izikhungo ezingancibilikisi zokuncibilikisa insimbi. Ingxenye eshisa kakhulu yodonga lwesithando somlilo esisebenza ngamandla kagesi amakhulu yenziwa ngezitini ezihlanganisiwe ze-magnesia-chrome, indawo yokuguguleka okukhulu kwesithando somlilo esingaphandle kwesithando yenziwe ngezinto zokwenziwa, kanti indawo yokuguguleka okuphezulu kwesithando sokuncibilikisa insimbi esingeyensimbi yenziwe ngezitini ezihlanganisiwe ze-magnesia-chrome nezinto zokwenziwa. Yenziwe ngezitini zemagnesia chrome. Ngaphezu kwalokho, izitini zemagnesia-chrome nazo ziyasetshenziswa endaweni evuthayo yamakhemikhali ajikelezayo kasimende kanye nama-regenerors e-glass kilns.

Izici ezingokomzimba nezingamakhemikhali zezitini eziphansi ze-chromium magnesia chrome nezitini eziqondile eziboshwe ze-magnesia chrome ezisetshenziswa kuma-kinsenti kasimende zimi kanje:

Okuhlobene nokwakheka nokusebenza kwalezi zinhlobo ezimbili zezitini, izimboni ezahlukahlukene kanye namaphuzu kufanele kunakwe emkhubeni wokusebenzisa ezinsikeni zikasimende.

Ulwelwesi lwezitini

Ihlanganiswe ngqo nezitini ze-magnesia-chrome ezingaphansi kwe-1500, ushintsho lomugqa lungafika ku- + 0.2% -0.8%. Kunamapuleti wensimbi noma udaka olukhiphayo esiyingini sezitini ukumunca le nto eyodwa enwetshiwe, ngakho-ke indlela ehlanzekile yokwakha ngaphandle kwamapuleti ensimbi noma udaka lomlilo ayinakusetshenziswa. , Futhi izitini eziphansi ze-chromium magnesia chrome zinikezwa umcamelo wamakhadibhodi, owokugcina ngosayizi wamakhadibhodi ka-2mm

2. Isiko sokubhaka

Izitini eziboshwe ngqo ze-magnesia-chrome zizwela kakhulu ekucindezelekeni kwangaphakathi kukalayini wezitini obangelwa ukufudumeza kanye ne-ellipticity yomzimba womlilo, ngakho-ke kudingeka ukulawula okuqinile.
Izitini eziboshwe ngqo ze-magnesia-chrome ziqukethe i-chromium eningi, zinokumelana okuphansi nokugqwala kwe-alkali emoyeni we-oxidizing, futhi izibopho zokubopha isigaba esiqukethe i-chromium ziyabhujiswa. Izitini kulula ukuzilimaza futhi zidala ukungcoliswa okukhulu emvelweni.

3. Ukumelana nokwehlisa umoya

Ukusabela okufanayo kwenzeka kuzo zombili izinhlobo zezitini endaweni enciphisayo, okucekela phansi isigaba sokuhlangana futhi ekugcineni kuholele ekulimaleni kwezitini. Ukuhlanganiswa okuqondile kwezitini ze-magnesia-chrome kuzothikamezeka kakhulu.

4. Ithonya ekwakheni isikhumba somlilo

Kuzokwakhiwa ungqimba olucebe ku-C4AF phakathi kukalayini wezitini ophansi we-chromium ne-high-iron magnesia-chrome kanye ne-clinker, ngakho-ke ukusebenza kwesikhumba somlilo kungcono. Ukusebenza kwesikhumba somlilo kuhlanganiswe ngqo nesitini se-magnesia-chrome kuyahluka ngokwakhiwa kwesitini. Lapho isikhumba somlilo sesivamile Lapho ukwakheka nokugcinwa kukuhle, izinga lokushisa kwendawo yezitini ngaphansi kwesikhumba somlilo lehla kakhulu, futhi akubalulekanga kakhulu ukuhlanganisa ngqo izinzuzo zamandla aphezulu wokushisa wesitina se-magnesia chrome.
Manje sekuphume izitini eziningana eziphansi ze-chrome magnesia-chrome, isitini esikhethekile esingenachrome, amandla okukhiqiza afinyelela ku-6000-10000T / h wekhompiyutha ye-PC, izinga lokushisa eliphakeme nokumelana nokushaqeka okushisayo kubaluleke kakhulu, bathuthukise ithiphu ehambelana nayo iSpar kuhlanganiswe nobumsulwa obuphezulu be-chromium-free magnesium ekhethekile isetshenziswa kakhulu endaweni yenguquko yamakhemikhali osimende.
