Dab tsi yog ladle breathable cib

Ladle cua-permeable cib yog cov khoom tshiab nrog lub neej ntev, txuag hluav taws xob thiab txo kev siv, nrog tsim qauv tsim, zoo thermal stability, yaig tsis kam, yaig tsis kam, thiab permeability tsis kam, siab tshuab-dhau tus nqi, nyab xeeb thiab txhim khu kev qha ua haujlwm, thiab kev pab lub neej ntev Tos ib pliag. Feem ntau siv hauv cov hlau ua, cov hauv paus thiab lwm yam.

Kev txhim kho thiab siv corundum-spinel ladle cov cib ua pa rau cov nplais loj ua kom zoo: Txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm cov nplais loj ua kom zoo rau cov cib ua pa, los ntawm kev txhais tau tias xws li cov txheej txheem ua kom zoo thiab ua kom kub kub, qhov ua tau zoo thiab siv cov txiaj ntsig tau ua tiav. Corundum-spinel ladle breathable cib ntawm cov tsoos chromium corundum ladle breathable cib. Cov cib ua tsis taus pa yog ua los ntawm cov phaj corundum ua cov khoom siv, fused dawb corundum zoo li hmoov, thiab ntxiv 6% ntshiab calcium aluminate cement, 5% Active Al-Al2O3 micropowder thiab 8% spinel, ntxiv rau qhov tsim nyog tus nqi ntawm chromium oxide thiab dej txo tus neeg sawv cev, tom qab kev sib tsoo tsim, ziab, khaws cua sov ntawm 1630 ° C rau ntau dua 3 teev. Cov pob zeb cua-permeable cib yog siv rau ntawm cov pob zeb ua kom huv loj kom tau Txais kom tau txais kev txaus siab ntawm kev siv txiv hmab txiv ntoo.

Lub pob zeb hauv qab argon tshuab raj cua-permeable cib txais cov khoom siv siab-purity homogenized, cov matrix yog pre-co-milled thiab sib xyaw, thiab qee cov ntaub ntawv raw tau ncaj qha los ntawm sab nraud, tsim nyog faib, thiab nruj me ntsis tswj kev tsim khoom raws li nrog rau thoob ntiaj teb kev tshaj lij thev naus laus zis xav tau. Cov khoom muaj qhov zoo ntawm lub zog siab, kev tiv thaiv yaig, kev yaig tsis kam, kev nkag mus tsis tau, thiab kev pab lub neej ntev.

Physical Qhov tseem ceeb ntawm lub cev thiab tshuaj lom neeg ntawm cov khoom: Al2O3% ≥95.0 Cr2O3% ≥3.0, pom kev porosity:% ≤16.0, ntom ntom ntom ntom ntom: g/cm3 ≥3.20, qhov ntsuas kub ib txwm muaj zog: MPa 110 ° C -60.0, 1500 ° C ≥100.0, 1600 ° C ≥120.0. Kev kub nyhiab siab zog: MPa 1400 ° C, 30min ≥10.0.

■ Siv ib feem: tshuab raj hauv qab.

Method Txoj kev tsim kho: smear av nkos tusyees rau saum npoo, thiab kev teeb tsa ruaj khov.
