Breathable cib thiab tundish refractories rau steelmaking

Cov khoom siv ntawm cov cib ua pa uas siv los ntawm cov chaw tsim khoom hlau yog corundum, spinel, thiab lwm yam, thiab cov khoom tseem ceeb muaj yog Al2O3 (cov ntsiab lus ≥90%), thiab tseem muaj me me ntawm MgO thiab Cr2O3. Lub luag haujlwm ntawm cov cib ua pa ua pa yog tshem tawm cov khoom tsis huv (cov khoom tsis xav tau, roj cua, thiab lwm yam) hauv cov hlau yaj thiab ua kom kub ntawm cov hlau yaj. Qee lub ladle yog ob lub cib ua pa, uas cov hauv paus ua pa tuaj yeem hloov tau.

(Duab) Slit-type cib ua pa

Lub tundish yog lub thawv ntim khoom tawg. Feem ntau, cov khoom siv tsis zoo siv los ntawm cov tuam ntxhab hlau tau siv los tiv thaiv qhov poob qis ntawm cov hlau yaj tom qab qis argon tshuab txheej txheem ntawm cov cib ua pa. Ua ntej tshaj plaws, nws tuaj yeem lees txais cov hlau yaj los txhawm rau txhawm rau txo qhov txaws lub zog ntawm cov hlau yaj. Tom qab ua tiav tsis tiav, nws yuav muab faib rau txhua lub pwm los ntawm lub taub hau. Qhov no tsis tsuas yog muaj txiaj ntsig zoo rau kev nyab xeeb thiab kev ntseeg tau ntawm kev ua kom zoo dua qub, tab sis kuj tseem muaj txiaj ntsig zoo rau lub cev thiab tshuaj lom neeg ntawm cov hlau yaj. . Qhov tundish feem ntau yog ua lub luag haujlwm ntawm kev txo siab, tswj kev ntws, tshem tawm kev suav nrog, khaws cia, thiab hloov cov hlau yaj. Cov ntaub ntawv uas tsis tuaj yeem ua rau tundish suav nrog cov paib cuam tshuam, cov dej ntws ruaj khov, cov qhov dej tso pa tawm, slag khaws cov phab ntsa weir, thiab lwm yam.

Zoo ib yam li cov khoom siv ntawm ladle cua-permeable cib, cov ntaub ntawv tundish siv los ntawm cov tuam ntxhab feem ntau yog corundum, thiab lwm yam, thiab tseem muaj qee qhov nyiaj ntawm magnesium oxide. Muaj peb qhov sib txawv tseem ceeb ntawm kev sib npaug ntawm corundum Al2O3, uas yog α-Al2O3, β-Al2O3, thiab γ-Al2O3. Qhov tawv ntawm corundum yog qhov thib ob tsuas yog pob zeb diamond. Corundum feem ntau yog siv rau qib cov khoom siv txhuam, saib thiab cov cuab yeej siv cov khoom siv tau zoo. Ruby-based siv lead ua khoom siv ua khoom siv laser. Rubies thiab sapphires yog ob qho tib si corundum cov zaub mov. Tsuas yog rau lub hnub qub ci, tsuas yog cov pob tshab-pob tshab thiab ci xim corundum tuaj yeem siv ua pob zeb. Cov xim liab hu ua ruby, thaum lwm cov xim ntawm corundum tau sau ua ke hu ua sapphire hauv kev lag luam.

Nqa cov cua-permeable cib thiab tundish refractories tseem ceeb heev rau cov tuam ntxhab hlau thiab muaj lub luag haujlwm tsis tuaj yeem hloov pauv. Firstfurnace@gmil.com, raws li cov kws tshaj lij tsim cov cib ua pa, tau tsim cov cib ua pa rau 18 xyoo. Nws muaj kev paub dhau los, thev naus laus zis zoo tshaj plaws, muaj ntawv pov thawj zoo, tsim tshwj xeeb, cov khoom tsim khoom hauv tsev thiab cov cuab yeej tsim khoom thawj zaug, thiab muaj peev xwm ntau lawm ntawm 120,000 teev. Lub teb chaws cov chaw tsim khoom loj tshaj plaws ntawm argon tshuab thiab tso pa tawm.
