Dab tsi yog Refractory Castables Feem ntau siv nyob rau hauv Kub Kub Kilns
Ua ntej, daim ntawv thov ntawm refractory castable nyob rau hauv cement rotary kiln.
Refractory castable tau dav siv nyob rau hauv cov tshiab qhuav cement rotary kiln. Raws li qhov sib txawv ntawm qhov chaw ua haujlwm ntawm lub qhov cub, cov refractory castables siv yog cov khoom siv refractory castables, low-cement refractory castables, ultra-low cement refractory castables, cement-free refractory castables, steel fiber refractory castables, anti-explosion refractory castables, anti-explosion refractory castables. -crust refractory castables, phosphate refractory castables, alkali resistant castables, thermal rwb thaiv tsev castables, nyob rau hauv tas li ntawd, tseem muaj tshiab castables xws li artesian refractory castables.
Qhov thib ob, daim ntawv thov ntawm refractory castable nyob rau hauv iav melting kiln.
Vim yog qhov yuav tsum tau ua ntawm qhov chaw ua haujlwm ntawm cov iav melting kiln nws tus kheej, cov khoom siv refractory castables yuav tsum muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam, muaj zog tiv thaiv iav yaig thiab tsis tshua muaj porosity. Lub refractory castables mas siv yog fused quartz castable, corundum castable, lub teeb mullite castable, zircon ramming khoom thiab hais txog.
Thib peb, daim ntawv thov ntawm refractory castable nyob rau hauv metallurgical kev lag luam.
(1) Refractory castable rau ironmaking system
Nyob rau hauv lub tshuab ua hlau, refractory castable yog siv ntau nyob rau hauv cov hlau channel ntawm moj tej tawg rauv, thiab ASC refractory castable feem ntau yog siv. ASC castable feem ntau tsis tshua muaj cement lossis ultra-low cement castable, feem ntau yog tsim los ntawm Al2O3 aggregate, SiC, carbon, refractory cement thiab ntau yam khoom siv. Kev siv cov khoom sib txawv, kev siv cov khoom sib txawv, xws li hauv cov kwj dej loj, slag ditch, ceg ditch thiab lwm yam.
(2) Refractory castable rau kub hlau pretreatment
Nyob rau hauv daim ntawv thov ntawm refractory castable nyob rau hauv kub hlau ladle, aluminium silicon carbide carbon castable mas yog siv nyob rau hauv lub cub tawg hauv qab, molten pas dej ua ke thiab slag kab. Cov tshuaj tsuag phom yog ib qho tseem ceeb ntawm cov khoom siv pretreatment ntawm cov hlau kub. Tam sim no cov khoom siv refractory siv hauv rab phom feem ntau yog nrum tag nrho, thiab nws cov khoom siv feem ntau yog Al2O3-SiO2. Cov tshuaj tsuag ib txwm ua los ntawm cov castable muaj cov yam ntxwv ntawm cov qauv zoo sib xws, tsis muaj kev sib koom ua ke, zoo thermal poob siab tsis kam thiab ua haujlwm ntev.
4. Refractory castable rau hluav taws xob rauv steelmaking
Daim ntawv thov ntawm refractory castable nyob rau hauv hluav taws xob rauv yog mas concentrated nyob rau hauv lub qhov cub npog. Cov txheej txheem castable prefabrication yog siv dav hauv cheeb tsam hluav taws xob daim duab peb sab. Cov khoom ntawm prefabricated block yog muab faib ua corundum, siab aluminium, mullite, tus neeg siv muab cov duab kos thiab siv qhov chaw, qhov kub thiab txias, cov chaw tsim khoom siv cov khoom tsim nyog refractory castable raws li cov duab kos rau hauv qhov chaw prefabricated, tom qab tu, ci. thiab kev xa khoom, thauj mus rau tus neeg siv qhov chaw tuaj yeem raug spliced ntawm qhov chaw.
5. Refractory castable rau cub refining
(1) RH rauv refractory castable. Ib qho me me ntawm siab alumina castable thiab aluminium-magnesium castable yog siv rau hauv ob sab phlu ntawm RH rauv. Al2o3-mgo ·Al2O3 castable integral hauv ob sab phlu los yog tshuaj tsuag filling ib lub hauv ob sab phlu yog siv nyob rau hauv sab sauv ntawm RH lub tshuab nqus tsev chamber. Monolithic aluminium-magnesium castable rau RH rauv impregnation raj sab nrauv phab ntsa.
(2) LF refractory castable rau cub. LF kab hlau rhuav phab ntsa feem ntau yog ua los ntawm high aluminium lossis corundum series castables. High aluminium-spinel refractory castable yog tsuas yog siv los cam khwb cia loj cib nyob rau hauv qhov cuam tshuam cheeb tsam ntawm qab cladding.
(3) Refractory castable rau CAS refining ntaus ntawv. CAS refining chav tsev yog muab faib ua rau sab sauv thiab qis, kev siv cov ntaub ntawv refractory yog castable; Sab sauv feem ntau yog siv qis qis Al2O3-SiO2 castable. Qhov qis dua yog siv fused corundum nrog MgO hmoov corundum spinel series castable. Txhawm rau kom ntev lub neej kev pab cuam ntawm lub cuab yeej nyob rau theem tom ntej, magnesia aluminium spray filler feem ntau yog siv.
(4) refractory castable rau ladle. Ntau yam ntawm refractory castable rau ladle mas siv aluminium-magnesium castable thiab aluminium-magnesium spinel castable.
6. Refractory castable rau nruam casting
Cov castables rau nruab nrab txheej yog: lub teeb castables (tsuas yog siv rau rwb thaiv tsev), siab aluminium los yog mullite artesian castables corundum thiab magnesium castables (siv rau npog hauv qab ua hauj lwm txheej).
