Cov ntaub ntawv siv hluav taws xob feem ntau hauv kev kho cua sov muaj xws liRefractory av nplaum cib, High Alumina cib, anti {{- carbourization cib, ntau aluminium carractory fibers thiab refraticate refractory fibers thiab refractory pleev xim. Ntawm lawv, Refractory Fireclay Cib yog qhov siv tshaj plaws hauv kev kho cua sov.
01 refractory clay cib
Cov ntaub ntawv raw ntawm refractory clay Hluav taws kub yog tsuas yog av nplaum thiab kaolin. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm kev refractory pob hluav taws yog al2o3 (kab ke pawg yog 30%), sio2 (pawg feem pua yog ntau tus hlau oxides. Cov av nplaum zoo tib yam tsis muaj zog acidic, nrog lub peev txheej me me, zoo siv hluav taws xob kom sov, thiab qhov siab tshaj plaws ntawm 1300 ~ 1400 degree. Cov av nplaum zoo tib yam siv hauv cov tshuab hluav taws xob ua kom sov, thiab cov pob zeb ua kom sov, thiab cov cib ua ke yuav corrode thiab puas tsuaj rau Hlau - chromium -} aluminium alloy. Av nplaum cov cib ua kom tawg yooj yim los ntawm kev yaig ntawm Co thiab H2 hauv kev tswj hwm cua.
02 High Alumina Cib
Qhov loj ntawm al2o3 nyob rau high- Alumina cib ntau dua 48%, thiab ob peb lub impurities tsawg. Cov pob zeb zoo nkauj siab tau muab faib ua peb qib kawm raws li Al2o3 ntau dua li 55%, thiab pawg feem ntau ntawm AL2O3 yog ntau dua 65%. High {{{}} Alumina Cib muaj qhov zoo ntawm kev kho cov kab ke ntawm cov kab ke
03 anti -} carburization cib
Nyob rau hauv ib lub huab cua kev muaj co thiab h2, Fe2o3 hauv refractory av cocks lossis refractory siab {}}}} CE2 (1) Fe2O {{{{11} h} h2=2 fe+3 h2o (2) metallic hlau yog tsim. Hlau kuj yog cov tshuaj tua kab mob rau cov tshuaj tiv thaiv hauv qab no, uas tau nrawm rau cov hlau pob zeb thiab tso nyiaj rau ntawm cov hlau ua kom lub cib lub cev xoob. Nyob rau tib lub sijhawm, cov nyiaj tso tawm ntawm cov pa roj hmab dub nyob hauv lub cib lub cev ua rau lub ntim ntawm lub cib kom nthuav dav. Qhov no yuav ua rau cov cua sov li ntawm cov av nkos detractory bricks lossis refractory siab {24 al} alumina cib yuav raug puas tsuaj ntxov. Yog li ntawd, qhov pawg feem ntawm Fe2o3 hauv anti- carburization cib yuav tsum muaj tsawg dua 1%.
04 Silicon Carbide Refractory
Cov tshuaj lom neeg tshuaj lom neeg ntawm silicon carbide regractory khoom yog tsuas yog sic. Nws tau ua siab ntev thiab siab- kev coj kub lub zog, lub zog ua tau zoo, thermal conductivity thiab hluav taws xob conductivity. Ua raws li cov txheej txheem tsim khoom, nws tuaj yeem siv los ua hluav taws xob cua sov ntawm qhov siab kub {4} kev kub taub hau ntawm qhov kub siab tshaj 1300℃thiab yooj yim corroded los ntawm alkaline slag.
05 Hnav Rwb thaiv tsev cib
Anthracite lossis Coke Hmoov, cov tshuaj no yog hlawv thaum lub sij hawm npaj ntawm refractory refractity, thiab txhim kho thermal rwb thaiv tsev. Cov tshuaj lom neeg ua npuas ncauj cov neeg sawv cev kuj tseem tuaj yeem muab ntxiv rau cov khoom xyaw kom txo qis qhov ntom ntom ntawm lub cib. Thaum lub teeb ci los yog ultra - Lub teeb ci ntsa iab yog siv los ua cov cub hluav taws xob, thiab lub sijhawm ua kom muaj cua sov kom tsis txhob muaj cua sov. Txawm li cas los xij, lub teeb ci ntsa iab thiab ultra - paomeight bricks kuj muaj ntau yam shortcomings. Vim yog lawv qhov qis qis, lawv lub zog compressive yog txo, thiab lub thawv softening point kuj tseem raug txo; Vim tias lawv cov porosity nce, lawv cov seem shrinkage (lossis nthuav dav) nce, thiab lawv txoj kev tawm tsam rau cov tshuaj yaig tsawg zuj zus.
06 Aluminium Kev Sib Tw Fiber Ntau
Aluminium Kev Fiber Refulation Fiber, tseem muaj cov khoom siv hluav taws xob sib kho, yog cov khoom siv hluav taws xob tshiab nrog ob qho kev tiv thaiv kev txhim kho. Raws li cov ntaub ntawv sib txawv, muaj cov txhuas silicate, quartz, alumina thiab graphite refractory fibers. Refractory fiber ntau muaj qhov zoo ntawm lub teeb qhov hnyav, cov tshuaj sov zoo, thiab lwm yam ntawm cov txheej txheem hluav taws xob lossis lwm yam.
07 amorphous refractory khoom siv
Amorphous refactories tuaj yeem ua rau hauv prefabricated blocks ntawm ntau yam duab ua kom muaj zog ntawm cov tshuab cua sov thiab pab txhawb kev txhim kho ntawm cov qauv cub tawg. Piv txwv li, lub ntsev rau ntawm lub tshuab ntsev ua kom muaj cov ntsev ua kom sov tau rau hauv cov rooj ua haujlwm ua kom muaj lub ru tsev thiab cub tawg. Amorphous cov ntaub ntawv refactories tuaj yeem muab faib rau hauv cov khoom siv cas, cov ntaub ntawv yas, tshuaj tsuag, cov ntaub ntawv txheej, cov ntaub ntawv kuaj cov qauv sib txawv. Feem ntau siv cov khoom siv tsis sib xws muaj cov khoom sib xyaw ua ke, cov khoom siv regractics, Refractory cov ntaub ntawv, refractory cov kua nplaum thiab cov cement. Refractory pob zeb ua yog ib qho tsis sib xws hauv kev kho cua sov, uas tuaj yeem muab faib ua cov pob zeb sov, uas tuaj yeem faib ua cov qhob cua Refractory qhob yog tsim ntawm peb ntu: binder, agnate thiab admixture, thiab qee zaum ib qho quav sib xyaw ntxiv. Nws cov txiaj ntsig yog tias nws tuaj yeem raug pov rau hauv kev sib xyaw ua hluav taws xob, uas yooj yim rau kev tsim cov nyom thiab lub tsev kom sov ntev; Qhov tsis zoo yog tias kev ua kom tsis muaj peev xwm tsawg dua li ntawm kev rov ua dua
08 refractory av nkos
Refractory av yog ib cov khoom siv refractory siv los sau cov pob txha caj qaum thaum siv cov hluav taws xob ua kom muaj lub zog ua kom muaj lub zog thiab kev ua kom huab cua. Refractory av nkos yog muaj los ntawm Clinker thiab phau ntawv. Nws cov refdoriness yog txiav txim siab los ntawm kev ua haujlwm raw thiab lawv cov proportions, uas feem ntau qis dua qhov tsis ua haujlwm ntawm cov hluav taws kub refractory. Txhawm rau ua cov av nkos refract thiab lub cev cib tau ua tiav cov txheej txheem sib raug zoo, uas yog, ntau tus cib yuav tsum siv cov av nkos teev. Piv txwv li, thaum tso cov av nplaum cov ceg ntoo, cov av nplaum ntawm 50% yog feem ntau siv cov av nplaum ntau dhau lawm, qhov ntau ntawm cov nyom ua ke thiab cov khoom siv ua ke ua ke ntau dhau ntawm lub sijhawm Sinining, uas yooj yim ua rau tawg ntawm Masonry Jointions. Qee zaum, txhawm rau txhim kho cov cua nruj ntawm lub cib lub cev, av nkos tov nrog cov dej iav kuj tseem siv tau. Ib qho ntxiv, phosphate refractory muaj lub zog siab, zoo} pa taws cov khoom sib xyaw ua ke, yog li cov khoom siv hluav taws xob nrawm tau siv ua cov av nkos refractory.
