Lub moj tej tawg sov rauv tapping channel siv los yeej cov khoom siv

Cov yam ntxwv ntawm carbon-muaj refactory rammer cov ntaub ntawv rau lub blast rauv rauv ceev, muaj zog hloov thiab muaj zog tiv thaiv kev muaj peev xwm. Nyob rau tib lub sijhawm, vim muaj kev siv ntau ntawm cov khoom zoo regractory, spinel corundum, spinel, tshwj xeeb yog qhov kev ua tau zoo li sifactory.

Qhov muaj pes tsawg leeg ntawm cov roj carbon-muaj cov ntaub ntawv sib txawv rau cov kev sib txawv ntawm cov hluav taws kub ua rau muaj kev sib txawv ntawm cov chaw ua hluav taws xob ua kom huv. Cov ntaub ntawv refractory siv rau cov ntaub ntawv sib tsoo hauv cov hluav taws kub thiab hluav taws xob sib xyaw ua ke thiab cov kab ke zoo nkauj thiab ntoo zoo nkauj Cov tshuab hluav taws xob tapping thiab slag channel thiab cov pob zeb me me thiab cov amorpholy thiab lwm cov amorphous cov khoom siv tau siv ua cov khoom siv carbon. Qhov ntau tshaj plaws qhov loj me ntawm refractory aggregate yog 8mm lossis 10 hli. Nyob rau hauv cov lus sib xyaw ntawm cov av nkos, 5 ~ 3mm yog qhov tseem ceeb, feem ntau 27%, 3 ~ 1%, thiab qis dua li 5mm. Refractory agregates tau npaj hauv ntau theem kom tau txais qhov siab tshaj plaws ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom Silicon carbide yog feem ntau ntxiv rau hauv daim ntawv ntawm hmoov zoo, thiab nws cov tshuaj yog 4% ~ 26%. Cov khoom siv carbon muaj xws li flake lossis earhalty graphite, asphalt coke thiab electrode hmoov muaj ib tug particle loj ntawm<1.0mm and a dosage of 3%~15%.

 

Cov hmoov nplej refractory siv rau cov khoom siv roj carbon-uas muaj cov ntaub ntawv ramming nyob rau hauv lub moj tej tawg sov rauv Tappast yog txiav txim siab los ntawm nws siv cov xwm txheej. Nws cov ntau yam suav nrog -alumina hmoov, dawb corundum lossis alumina-raws corundum hmoov, thiab lwm yam lossis lwm yam lossis lwm yam yog li 15%; Txhawm rau txhim kho cov plasticity thiab sintering cov khoom siv ntawm cov ntaub av ramming, cov hmoov av muag muag feem ntau ntxiv, thiab ntau npaum li cas yog 3% ~ 6%. Txhawm rau txhim kho kev ua tau zoo, qee tus kuj ntxiv silica fume thiab boric acid.

Lub binders siv rau cov khoom siv roj carbon monours refractory txuas nrog cov khoom siv hluav taws xob sib txuas, cov tshuaj phosphoric, thiab lwm yam tshuaj ntsuab feem ntau 1.5% ~ 8.5%. Nws admixtures suav nrog surfactants, uas tuaj yeem txhim kho kev tawm tsam ntawm Carbon cov ntaub ntawv nrog dej thiab pab txhawb kev hloov pauv thiab kev cog lus. Thaum siv cov kua qaub acidic, inhibitors xws li oxalic acid yuav tsum tau ntxiv rau kev ua yeeb yam ntawm cov acid thiab txuas lub txee lub neej ntawm cov ntaub ntawv ramming. Thaum siv cov av nplaum binder, diluent dispersant yuav tsum tau ntxiv kom txo qis viscosity ntawm av nplaum, txo kev noj dej thiab txhim kho kev ua haujlwm.

Moj tej hluav taws xob rauv Tapping cov khoom ntxhua khaub ncaws paj hauv carbon-muaj refractory ramming cov khoom, ntxiv rau qee zaum siv. Piv txwv li, cov hlau silicon cov hmoov yog ntxiv rau txhim kho oxidation tsis kam. Vim tias cov hlau silicon hmoov hws nrog c ntawm qhov kub siab los ua cov pa oxidation thiab txhim kho cov pa oxidation thiab txhim kho cov khoom siv hluav taws xob thiab txo qis ntawm cov khoom siv ramming ramming. Tus nqi tsim nyog ntawm cov hlau silicon feem ntau yog 2% ~ 4%. Ntxiv Borax tuaj yeem tsim B2O {4}} C yog cov kev daws nrog c ntawm nruab nrab kub, uas tuaj yeem txhim kho lub zog kub nruab nrab, lub zog nruab nrab kub.

Nws yuav tsum tau taw qhia tias thaum muaj cov pa roj carbon-muaj cov khoom siv tau npaj, cov hmoov av, birer, binder thiab additive feem ntau tsis siv ib leeg, tab sis ua ke. Piv txwv li, cov hlau ditch ramming cov khoom rau nruab nrab lub tshuab hluav taws xob siv cov xim av hauv av thiab cov hmoov av, thiab siv cov ntaub av uas ua kom sib xyaw thiab phosphate comporite.

Al2O {3-} sic-c refractory ramming loj yog cov pa hluav taws xob, tshwj xeeb cov tshuab hluav taws xob ua kom tawg thiab cov khoom siv hluav taws xob me me thiab lwm yam khoom siv thermal. Daim ntawv thov ntawm carbon-muaj refractory ramming hlua yog tseem muaj ntau. Cov nyhuv zoo thiab cov nyiaj ntau ntawm daim ntawv thov tau nyiam cov xim ntawm lub ntiaj teb.

Ramming materiais rau lub tshuab tawg ua kom sov tawg tau tsim nrog ramming tshuab lossis phau ntawv cua rammer. Lawv siv nyob rau hauv BSW thiab cov hlau tapping nqi rau ntau dua 60000 t dhuav.
