Tshiab Refractory
Cov ntaub ntawv refractory feem ntau xa mus rau cov khoom siv tsis muaj hlau tsis muaj hlau nrog cov refractoriness saum 1580oC. Nws suav nrog ntuj ores thiab ntau yam khoom tsim los ntawm cov txheej txheem qee yam raws li qee lub hom phiaj. Nws muaj qee yam khoom siv hluav taws xob kub thiab qhov ntim zoo, thiab yog cov khoom siv tseem ceeb rau ntau yam khoom siv kub.
1, acid refractories feem ntau yog xa mus rau SiO2 cov ntsiab lus ntawm ntau tshaj 93% ntawm cov refractory, nws lub ntsiab feature yog nyob rau hauv kub kub tuaj yeem tiv taus yaig ntawm acid slag, tab sis yooj yim rau hnov mob nrog alkaline slag.
2, yooj yim refractories feem ntau xa mus rau magnesium oxide los yog magnesium oxide thiab calcium oxide raws li lub ntsiab Cheebtsam ntawm lub refractory. Lub refractories ntawm cov refractories yog siab, thiab lub peev xwm los tiv thaiv alkaline slag muaj zog.
3, aluminium silicate refractory yog hais txog SiO2-Al2O3 yog cov khoom tseem ceeb ntawm refractory, raws li cov ntsiab lus ntawm Al2O3 tuaj yeem muab faib ua semi-siliceous (Al2O3 15~ 30%), av nplaum ( Al2O3 30~48%), siab txhuas (Al2O3 ntau dua 48%) peb pawg.
4, fusible cam khwb cia refractory khoom yog hais txog ib tug tej yam txoj kev ntawm kub melting ntawm lub compound, poured rau hauv ib tug tej yam zoo li refractory khoom.
5, nruab nrab refractories xa mus rau qhov kub thiab txias thiab acidic los yog alkaline slag tsis yooj yim rau cov ntaub ntawv refractory, xws li carbon refractories thiab chrome refractories. Qee qhov siab aluminium refractories kuj raug cais raws li qhov no.
6, tshwj xeeb refractories yog tshiab inorganic non-metallic cov ntaub ntawv tsim los ntawm cov tsoos ceramics thiab dav refractories.
7, amorphous refractory khoom yog tsim los ntawm refractory aggregate thiab hmoov, binder los yog lwm yam admixture ntawm ib tug tej yam kev faib ua feem ntawm cov sib tov, yuav siv tau ncaj qha los yog ntxiv tsim nyog kua deployment tom qab siv. Amorphous refractory yog ib yam tshiab ntawm refractory yam tsis muaj calcination, thiab nws refractoriness tsis tsawg tshaj li 1580 degree.
Nrog Tuam Tshoj txoj kev nkag mus rau WTO, cov khoom siv hluav taws xob hauv tsev thiab cov khoom siv refractory tau ntsib cov kev sib tw ntawm txawv teb chaws lub neej ntev, kev txuag hluav taws xob thiab cov khoom siv tshiab, thiab kev sib tw ua lag luam tau nce zuj zus. Hauv qhov no, cov kws tshaj lij tau taw qhia tias Tuam Tshoj txoj kev lag luam cov khoom siv tiv thaiv yuav tsum ua kom zoo dua thiab kev hloov kho, kev siv cov kev sib xyaw ua ke muaj zog, tshem tawm cov kab ntau lawm rov qab, ntxiv dag zog rau kev tshawb fawb thiab kev tsim khoom thiab kev tswj hwm, kho cov qauv khoom, txhawm rau ua kom tau raws li qhov xav tau. kev xav tau ntawm kev txhim kho steel kev lag luam hauv tsev thiab txawv teb chaws sai li sai tau.
Cov refractories feem ntau siv yog silicon cib, semi-silicon cib, av nplaum cib, siab aluminium cib, magnesium cib thiab lwm yam.
Feem ntau siv cov ntaub ntawv tshwj xeeb yog AZS cib, corundum cib, ncaj qha sib txuas magnesium-chromium cib, silicon carbide cib, silicon nitride bonded silicon carbide cib, nitride, silicide, sulfide, boride, carbide thiab lwm yam ntaub ntawv uas tsis yog-oxide refractory; Calcium oxide, chromium oxide, alumina, magnesium oxide, beryllium oxide thiab lwm yam ntaub ntawv refractory. Feem ntau siv thermal rwb thaiv tsev refractories yog diatomaceous ntiaj teb cov khoom, asbestos khoom, rwb thaiv tsev panels thiab hais txog.
Feem ntau siv amorphous refractory cov ntaub ntawv yog kho, refractory ramming, refractory castable, refractory yas, refractory av nkos, refractory spray muab tub lim, refractory casting khoom, refractory xim, lub teeb refractory castable, cannon av nkos thiab hais txog.
Daim ntawv no qhia txog kev txhim kho tshiab ntawm cov tshuab refractory, tsim qauv qauv, cov txheej txheem xaiv cov khoom siv, txheej txheem thev naus laus zis, kev tswj cov txheej txheem ntxhia, cov khoom ua tau zoo thiab kev siv tshuab ntawm ntau cov khoom siv tshiab refractory. Cov refractories tshiab muaj feem ntau yog: A12O3-TiO2-SiO2 series refractories, MgO-A12O3-TiO2 series refractories, MgO-CaO-TiO2 series refractories, MgO-SiC-C series reractories , nanotechnology MgO-C cib, MgO-AL2O3-AIN series refractories, MgO-La2O3 series refractories, thiab lwm yam.
