Linear Hloov Tus Nqi
Lub ntim ruaj khov ntawm cov yas refractory yog ntsuas los ntawm nws cov kab hloov pauv thiab tus cwj pwm thermal expansion.
Thaum lub sij hawm pib cua sov, me me shrinkage tshwm sim vim noo noo evaporation thiab lub cev qhuav dej. Nrog rau qhov kub thiab txias ntxiv, tswj kev nthuav dav maj mam tshwm sim. Tom qab 3-4 lub voj voog cua sov thiab cua txias, qhov kev hloov pauv mus tas li yuav muab piv rau cov khoom siv hluav taws xob zoo li qub thiab siab -alumina bricks, qhia qhov kev ua haujlwm ruaj khov nyob rau hauv thermal cycling.
Kev Txhim Kho Lub Zog
Yas refractory feem ntau undergoes sintering ntawm qhov kub siab tshaj 1200-1300 degree, uas ua rau ib tug tseem ceeb nce nyob rau hauv txias crushing zog.
Hauv qab 1100-1200 degree, qhov kub hloov pauv ntawm qhov tawg feem ntau siab dua qhov txias modulus ntawm rupture.
Saum toj no 1200 degree, ib nrab softening yuav tshwm sim nyob rau hauv tej qib, ua rau lub kub lub zog yuav txo tus txheeb ze rau lub txias zog.
Thaum qhov kub thiab txias tshaj 1200 degree, kub thiab txias zog sib txawv heev vim kev hloov ntawm cov qauv thiab theem evolution.
Thermal Shock Resistance
Piv nrog rau refractory cib thiab lwm yam monolithic refractories ntawm zoo sib xws, aluminosilicate yas refractory exhibits superior thermal shock kuj.
Qhov kev ua tau zoo no raug ntaus nqi rau:
Qhov tsis muaj qhov hloov pauv hloov pauv hloov pauv hloov pauv hloov pauv thaum lub sijhawm cua sov thiab kev pabcuam, txo cov qauv kev ntxhov siab.
Lub microstructure nyob ze ntawm lub ntsej muag kub muaj feem ntau ntawm mullite thiab cristobalite microcrystals nrog cov ntsiab lus iav theem qis.
Ib qho kev hloov maj mam hloov hauv theem muaj pes tsawg leeg thiab lub cev muaj zog los ntawm lub ntsej muag kub mus rau sab txias, txo qis thermal stress concentration.
Hom Hom
Feem ntau siv cov yas refractory muaj xws li:
Fireclay-raws li
High -alumina
Corundum-raws li
Kev Pabcuam Kub
Qhov kev pabcuam kub ntawm cov yas refractory nyob ntawm cov khoom muaj pes tsawg leeg:
Fireclay yas refractory:1300-1400 degree
Premium fireclay qib:1400-1500 degree
High -alumina yas refractory:1500-1600 degree
Corundum{0}}raws li yas refractory:1500-1900 degree
Kev teeb tsa & Qhuav -Tshaj Tawm Yuav Tsum Tau
Txhawm rau kom lub cev qhuav dej kom zoo thaum ci:
Lub qhov cua nrog txoj kab uas hla ntawm 3-6 hli yuav tsum tau ua ntej-drilled ntawm 100-150 hli ntawm lub ntsej muag kub.
Lub qhov tob yuav tsum yog kwv yees li ob -feem peb ntawm lub hauv ob sab phlu.
Cov pob qij txha nthuav dav 1-3 hli dav thiab 50 hli sib sib zog nqus yuav tsum tau muab thaum lub sijhawm ntawm 1000-1500 hli kom haum rau thermal expansion thiab contraction.
Yas refractory feem ntau tsis xav tau ib txwm kho. Txawm li cas los xij, vim tias muaj dej- cov khoom siv ntxiv, qhov saum npoo yuav tsum tau npog nrog cov yas zaj duab xis tam sim tom qab kev teeb tsa los tiv thaiv kom tsis txhob ya raws ntxov ntxov thiab tawg.
Thaum lub sij hawm ci, qhov kub yuav tsum tau nce ntxiv, feem ntau ntawm tus nqi ntawm 30-50℃ib teev, tshwj xeeb tshaj yog:
Hauv qab 200℃(moisture tshem tawm theem)
Nyob ib ncig ntawm 800℃(theem transformation theem)
Cov cua sov qeeb ntawm cov theem no pab tiv thaiv kev puas tsuaj ntawm cov qauv.
Txheej Txheem & Kev Tsim Kho
Yas refractory linings yog ntsia los ntawm ramming thiab anchoring, tsim ib tug tuab monolithic ua hauj lwm txheej.
Qhov khoob ntawm cov pob zeb thauj tog rau nkoj lossis cov hanger cib yog ntim nrog cov khoom siv yas refractory.
Compaction yog ua los ntawm pneumatic rauj los yog tamping tshuab.
Kev txhim kho yog nqa tawm tsis tu ncua nyob rau hauv cov txheej txheej, nrog rau lub qhov cub hauv qab.
Qhov saum npoo yog roughened, vent qhov yog punched, thiab expansion pob qij txha raug txiav raws li xav tau.
Kev Ua Haujlwm & Kev Pabcuam Lub Neej
Yas refractory linings muaj:
Muaj zog structural kev ncaj ncees
Kev ua tau zoo ntawm sintering
Lub zog siab ntawm qhov kub siab
Vim cov yam ntxwv no, lub hauv ob sab tiv thaiv tev thiab spalling thaum ua haujlwm. Raws li kev ua haujlwm ib txwm muaj, lub neej kev pabcuam tuaj yeem ncav cuag li 10-15 xyoo, nyob ntawm kev ua haujlwm tsis ua haujlwm.
Hlau:Sab hauv rau cov qhov cub kub blasting, converter ducts, thiab ladle preheaters.
Tsis yog -ferrous:Electrolytic hlwb, smelting converters, roasting furnaces.
Cov khoom siv hauv tsev:Cement kilns, iav regenerators, ceramic kilns.

1. Kev npaj substrate
Lub substrate nto yuav tsum tau ntxuav kom huv si ua ntej installation. Xyuas kom meej tias nws tsis muaj plua plav, roj, cov khoom xoob, thiab lwm yam kab mob. Txhua qhov tawg, tawg, lossis qhov tsis xws luag yuav tsum tau kho ua ntej kom muaj lub suab nrov rau daim ntawv thov.
2. Tsis muaj dej ntxiv
Cov khoom siv yog npaj rau kev siv. Tsis txhob ntxiv dej lossis kho qhov sib xws ntawm qhov chaw, vim qhov no yuav txo qis kev sib txuas ntawm lub zog thiab kev ua haujlwm tag nrho.
3. Txheej Ramming
Txais yuav txheej txheej txheej txheej txheej los xyuas kom meej compaction. Txhua txheej yuav tsum tau ua kom zoo tamped los tiv thaiv cov voids sab hauv thiab cov txheej txheem looseness.
4. Kev kho ntawm kaum thiab qhov chaw tsis xwm yeem
Kev saib xyuas ntxiv yuav tsum tau coj mus rau ntawm cov ces kaum, qhov rooj rau qhov cub, qhov cub tawg, thiab lwm qhov tsis sib xws. Cov cheeb tsam no yuav tsum tau ua tib zoo compacted kom nruj kev sib raug zoo nrog lub substrate thiab uniform ntom.
5. Tshaj tawm -Kev txhim kho kho
Tom qab kev teeb tsa, tso cai rau cov khoom siv los kho hauv cov xwm txheej zoo li qub. Tsis txhob muaj kev vibration, mechanical cuam tshuam, lossis cua sov ua ntej lub sijhawm no.
6. Teem caij cua sov
Qhov pib qhuav- tawm thiab cua sov txheej txheem yuav tsum ua raws li kev tswj qhov kub thiab txias - nce. Cov cua kub yuav tsum maj mam ua kom tsis txhob tawg los yog tev tawm los ntawm kev hloov kub sai.

Q1: Dab tsi yog qhov txawv ntawm cov yas refractory thiab refractory castables?
A: Yas refractory yog npaj rau kev siv thiab tsis tas yuav tsum tau dej ntxiv, muab kev yooj yim dua thaum lub sij hawm installation. Nws yog tshwj xeeb tshaj yog haum rau cov qauv complex thiab kho daim ntawv thov. Refractory castables, ntawm qhov tod tes, yog qhov zoo dua rau cov loj - nplai ib qho casting thiab monolithic hauv ob sab phlu.
Q2: Cov yas refractory puas tuaj yeem siv rau hauv siab -kev siv kub?
A: Yog. Cov khoom siv sib txawv-xws li fireclay, high-alumina, los yog corundum- raws qib- tuaj yeem xaiv tau raws li qhov yuav tsum tau ua qhov ntsuas kub kom ua tau raws li qhov kub siab - ua haujlwm kub.
Q3: Puas yog cov cuab yeej tshwj xeeb xav tau rau kev teeb tsa?
A: Feem ntau, tsis tas yuav muaj cov khoom loj -. Kev teeb tsa feem ntau yog ua los ntawm phau ntawv lossis kev siv tshuab ramming thiab tamping.
Q4: Yuav ua li cas yog tias cov khoom puas thaum lub sij hawm thauj mus los?
A: Peb txhawb nqa tag nrho cov ntim khoom kom txo qis kev pheej hmoo ntawm kev thauj mus los. Yog tias pom muaj kev puas tsuaj thaum tau txais, thov muab cov duab, yeeb yaj kiab, thiab cov ntaub ntawv xa khoom cuam tshuam tsis pub dhau 48 teev. Tom qab ua pov thawj, peb yuav npaj dawb hloov cov khoom puas lossis muab lwm txoj kev daws teeb meem los ntawm kev pom zoo.
Q5: Lub txee lub neej thiab kev pom zoo cia yog dab tsi?
A: Nyob rau hauv qhov chaw cia khoom kom zoo- txias, qhuav, zoo- qhov cua, tiv thaiv los ntawm tshav ntuj ncaj qha thiab los nag, thiab nrog kev ntim khoom tsis zoo - lub txee lub neej yog 6 lub hlis.
Khaws cov khoom kom deb ntawm cov khoom siv hluav taws xob thiab khaws cov khoom sib txawv thiab qib sib txawv kom tsis txhob sib xyaw.
Q6: Cov ntaub ntawv dab tsi xav tau rau kev hloov kho khoom?
