Nov yog qhov hais txog magnesia carbon cib: nws yog cov khoom uas ua rau niaj hnub steelmaking tswv yim, thiab nws kuj yog qhov yooj yim refractory rau mis-spec. Magnesia carbon cib khub tuag hlawv magnesia nrog flake graphite, sib raug zoo los ntawm resin, thiab cov ntsiab lus carbon txiav txim siab yuav ua li cas nws ciaj sia slag nres thiab thermal shock. Nyob rau hauv feem ntau ladles, lub hauv ob sab phlu ua hauj lwm khiav MT-14A ntawm lub slag kab thiab MT-10A nyob rau hauv cov phab ntsa - nrog MT-18A qhov twg cov slag yog txhoj puab heev los yog cov hlau tuav lub tshav kub ntev. Tau cov qhab nia zoo thiab koj cov ntaub ntawv kav ntev. Ua tsis ncaj ncees lawm thiab koj rov ua dua ib lub ladle nruab nrab ntawm kev sib tw. Phau ntawv qhia no suav nrog cov qib, tus lej txhais li cas hauv kev pabcuam, thiab yuav xaj lawv li cas los ntawm Tuam Tshoj. Peb yog TOPOWER, Tuam Tshoj refractory Hoobkas muab cov nroj tsuag steel hauv 30+ lub teb chaws txij li xyoo 2008.
Magnesia Carbon Cib yog dab tsi?
Magnesia carbon cib (MgO-C cib) yog ib qho zoo li refractory ua los ntawm fused los yog sintered magnesia, flake graphite, thiab ib tug resin los yog pitch binder. Cov pa roj carbon ua ob txoj haujlwm. Nws tsis ntub molten slag, yog li slag swb tawm es tsis txhob nkag mus. Thiab nws ua kom sov sai sai, yog li thermal shock tau absorbed.
Qib npe - MT-10A, MT-14A, MT-18A - qhia koj cov ntsiab lus carbon: 10%, 14%, lossis 18% los ntawm qhov hnyav. Magnesia yog lub cev pob txha; carbon yog daim ntaub thaiv.
MgO-C bricks yuav luag ib txwm ntsia tsis muaj hluav taws xob. Lawv raug xa raws li - yog thiab kho los ntawm thawj qhov cua sov. Cov ntaub ntawv cob qhia tau teeb tsa ntawm 200-300 degree, uas yog vim li cas cov cib no tswj cov cua kub ceev yam tsis muaj kev tawg - ib qho cuab yeej uas ua rau lawv lub neej qub rau BOF thiab EAF hauv ob sab phlu.
Qhov zoo pib ntawm cov khoom siv raw. Fused magnesia los ntawm hluav taws xob arc rauv nqa qhov siab tshaj plaws thiab purity; sintered magnesia los ntawm ncej kilns raug nqi tsawg dua thiab ua haujlwm nyob rau hauv feem ntau ntawm cov phab ntsa. Cov graphite yuav tsum loj -flake, thiab cov resin ib phenolic nrog viscosity zoo ib yam. Thaum peb tsim nyog rau cov khoom lag luam magnesia carbon cib tus kheej lub tshuab, peb cov khoom siv no yog thawj yam peb kuaj.
Magnesia Carbon Brick Qib: Tus lej txhais li cas
MT-10A yog cov neeg ua haujlwm dav dav: 10% carbon, magnesia ntawm 94-96%, pom porosity ncig 3-4%, txias crushing zog 35-45 MPa. Nws kab ladle phab ntsa, sab sauv, thiab EAF sidewalls qhov twg slag nres nyob nruab nrab.
MT-14A ntxiv cov pa roj carbon rau cov kab slag. Qhov ntawd yog thaj chaw uas slag ntsib hlau. Porosity nyob qis dua 4%, CCS khiav 40-50 MPa. Cov pa roj carbon ntau dua muab cov slag zoo dua thiab thermal shock kam rau ua. MT-14A yog tus qauv slag kab qib hauv feem ntau cov nroj tsuag steel.
MT-18A yog qib hnyav nrog 18% carbon. Siv nws qhov twg slag yog txhoj puab heev, steel qhov chaw nyob ntev, los yog kub khiav saum 1,700 degree. Nws raug nqi ntau dua. Nws khwv tau nws tus nqi hauv ladle slag kab thiab EAF slag zones.
Antioxidants tseem ceeb npaum li carbon. Aluminium thiab Al-Mg alloy hmoov tiv thaiv cov graphite los ntawm oxidation ntawm 1,300-1,600 degree, qhov uas tsis muaj kev tiv thaiv carbon yuav hlawv tawm. Nug rau pob antioxidant hauv kev sau ntawv ntawm txhua qhov kev tsocai. Ob lub MT-14A ntau los ntawm cov mills sib txawv tuaj yeem coj txawv txawv hauv qhov cub uas muaj oxygen. Ib lo lus "nws muaj antioxidants" tsis yog ib qho spec.
Yuav Ua Li Cas Sib Cuam MgO- Qib C rau Koj Thaj Chaw
Xav txog ib tug ladle nyob rau hauv peb cheeb tsam: phab ntsa, slag kab, thiab hauv qab. Txhua tus tau txais qib sib txawv, thiab sib xyaw kom raug yog ib nrab ntawm engineering.
Phab ntsa thiab sab saud: MT-10A. Nruab nrab slag hu, steel ntxuav los ntawm 1,600-1,650 degree. MT-10A tuav tau zoo thiab raug nqi tsawg dua cov qib siab dua.
Slag kab: MT-14A yam tsawg kawg nkaus, MT-18A rau aggressive slags los yog ntev tuav lub sij hawm. Qhov no yog thaj tsam uas ua tsis tau ua ntej, yog li nws tau txais cov khoom siv zoo tshaj plaws. Peb txoj cai: yog tias cov kab slag ua tsis tiav ua ntej cov phab ntsa, txhim kho cov kab slag - tsis txhob hloov kho txhua yam.
