Refractory chaw tsim tshuaj paus kub sandblasting castable dawb corundum xuab zeb zoo hmoov

Cov khoom siv refractory

tswvyim:
Ib chav kawm ntawm inorganic non-metallic cov ntaub ntawv nrog ib tug refractoriness tsis tsawg tshaj li 1580 ° C.Refractoriness yog hais txog qhov kub ntawm Celsius uas tus qauv refractory cone tiv thaiv qhov kev txiav txim siab kub yam tsis muaj softening thiab melting nyob rau hauv cov xwm txheej tsis muaj load.Txawm li cas los xij, tsuas yog lub ntsiab lus ntawm refractoriness tsis tuaj yeem piav qhia txog cov ntaub ntawv refractory, thiab 1580 ° C tsis yog qhov tseeb.Nws yog tam sim no txhais tau tias yog tag nrho cov ntaub ntawv uas nws lub cev thiab tshuaj muaj zog tso cai rau nws siv nyob rau hauv ib tug kub kub ib puag ncig yog hu ua refractory ntaub ntawv.Cov ntaub ntawv refractory yog dav siv hauv metallurgy, tshuaj lom neeg kev lag luam, roj av, tshuab tsim, silicate, fais fab thiab lwm yam kev lag luam.Lawv yog cov loj tshaj plaws hauv kev lag luam metallurgical, suav txog 50% txog 60% ntawm tag nrho cov khoom tsim tawm.

nyhuv:
Cov ntaub ntawv refractory yog siv nyob rau hauv ntau yam kev lag luam ntawm lub teb chaws xws li steel, non-ferrous hlau, iav, cement, ceramics, petrochemicals, machinery, boilers, lub teeb kev lag luam, hluav taws xob kev lag luam, tub rog kev lag luam, thiab lwm yam. xyuas kom muaj kev lag luam ntau lawm thiab kev tsim kho thev naus laus zis ntawm cov kev lag luam saum toj no.Nws plays lub luag hauj lwm tseem ceeb thiab irreplaceable nyob rau hauv txoj kev loj hlob ntawm high-temperature industrial ntau lawm.
Txij li xyoo 2001, tau tsav los ntawm kev loj hlob sai ntawm kev lag luam kub kub xws li hlau thiab hlau, cov hlau tsis muaj hlau, petrochemicals, thiab cov khoom siv hauv tsev, kev lag luam refractory tau tuav lub zog loj hlob zoo thiab tau dhau los ua tus tsim khoom loj thiab xa tawm cov ntaub ntawv refractory nyob rau hauv lub refractory. ntiaj teb.Nyob rau hauv 2011, Tuam Tshoj lub refractory ntau lawm accounted rau kwv yees li 65% ​​ntawm lub ntiaj teb no tag nrho, thiab nws cov ntau lawm thiab muag ntim tsis tu ncua ranked thawj nyob rau hauv lub ntiaj teb no.
Kev txhim kho ntawm kev lag luam refractory yog ze ze rau kev khaws cia ntawm cov khoom siv hauv tsev.Bauxite, magnesite thiab graphite yog peb cov khoom tseem ceeb refractory.Tuam Tshoj yog ib tug ntawm peb lub ntiaj teb no loj tshaj exporters ntawm bauxite, lub ntiaj teb no loj reserves ntawm magnesite, thiab ib tug loj exporter ntawm graphite.Cov peev txheej nplua nuj tau txhawb nqa Tuam Tshoj cov ntaub ntawv refractory rau ib xyoo caum ntawm kev loj hlob sai.
Nrog rau lub sijhawm "Twelfth Five-Year Plan", Tuam Tshoj tab tom ua kom tshem tawm cov khoom siv hluav taws xob tsis tu ncua thiab muaj peev xwm siv hluav taws xob ntau.Kev lag luam yuav tsom mus rau kev txhim kho thiab txhawb nqa lub zog txuag hluav taws xob tshiab, kev txhim kho cov cuab yeej siv hluav taws xob txuag hluav taws xob, kev tswj hluav taws xob, kev tswj emissions ntawm "peb cov khib nyiab" thiab kev siv cov peev txheej ntawm "peb pov tseg" Recycling, thiab lwm yam. Kev siv cov khoom siv rov ua dua tshiab thiab rov qab siv cov ntaub ntawv refractory tom qab siv, txo cov khoom pov tseg emissions, txhim kho kev siv cov peev txheej, thiab txhawb kev txuag hluav taws xob thiab txo qis emission.
Txoj cai "Refractory Industry Development Policy" taw qhia tias chav tsev noj cov khoom siv refractory hauv Tuam Tshoj txoj kev lag luam steel yog kwv yees li 25 kilograms ib tuj ntawm cov hlau, thiab nws yuav poob qis dua 15 kilograms los ntawm 2020. Hauv 2020, Tuam Tshoj cov khoom refractory yuav nyob ntev dua. , ntau zog-npaum, tsis muaj kuab paug, thiab functionalized.Cov khoom yuav ua tau raws li cov kev xav tau ntawm kev loj hlob ntawm lub teb chaws xws li metallurgy, cov khoom siv hauv tsev, tshuaj lom neeg, thiab kev lag luam tawm tshiab, thiab yuav ua rau kom cov ntsiab lus ntawm cov khoom xa tawm.

Cov khoom siv refractory muaj ntau yam thiab siv sib txawv.Nws yog ib qho tsim nyog rau kev tshawb fawb cais cov ntaub ntawv refractory los pab txhawb kev tshawb fawb, kev xaiv thiab kev tswj hwm.Muaj ntau ntau txoj hauv kev rau cov khoom siv refractory, suav nrog kev faib cov khoom siv tshuaj lom neeg, tshuaj lom neeg muaj pes tsawg leeg, kev faib cov txheej txheem tsim khoom, thiab kev faib cov khoom siv morphology.

Kev faib tawm:
1. Raws li qib ntawm refractoriness:
Cov khoom siv hluav taws xob zoo tib yam: 1580 ℃ ~ 1770 ℃, cov khoom siv refractory siab heev: 1770 ℃ ~ 2000 ℃, cov khoom tshwj xeeb qib refractory:> 2000 ℃
2. Cov khoom siv refractory tuaj yeem muab faib ua:

Acid refractory, nruab nrab refractory, alkaline refractory
4. Kev faib tawm raws li tshuaj lom neeg muaj pes tsawg leeg
Qhov kev faib tawm no tuaj yeem ua tus yam ntxwv ntawm cov qauv yooj yim thiab cov yam ntxwv ntawm ntau yam khoom siv refractory.Nws yog ib qho kev faib ua feem ntau hauv kev tsim khoom, siv, thiab kev tshawb fawb txog kev tshawb fawb, thiab muaj qhov tseem ceeb ntawm kev siv qhov tseem ceeb.
Silica (silica), txhuas silicate, corundum, magnesia, magnesia calcium, aluminium magnesia, magnesia silicon, carbon composite refractories, zirconium refractories, tshwj xeeb refractories
6. Kev faib tawm ntawm cov ntaub ntawv tsis zoo li refractory (qhia raws li txoj kev siv)
Castables, tshuaj tsuag txheej, ramming cov ntaub ntawv, yas, tuav cov ntaub ntawv, projection cov ntaub ntawv, smear cov ntaub ntawv, qhuav vibrating cov ntaub ntawv, nws tus kheej ntws castables, refractory slurries.
Cov refractories nruab nrab yog tsim los ntawm alumina, chromium oxide lossis carbon.Cov khoom lag luam corundum muaj ntau dua 95% alumina yog cov khoom siv zoo refractory nrog ntau yam kev siv.
Chiping Wanyu Kev Lag Luam thiab Kev Lag Luam Co., Ltd., tsim nyob rau xyoo 2010, tshwj xeeb hauv kev tsim cov khoom hnav-resistant thiab refractory: dawb corundum seem xuab zeb, nplua hmoov, thiab granular xuab zeb series khoom.
