China Zirconia Corundum Brick ifektri nabakhiqizi | Rongsheng

Incazelo emfushane:

Isitini se-Zirconia corundum siwuhlobo lomzimba oqinile omhlophe owenziwe ngempushana ye-alumina futhi cishe u-65% ZrO2 kanye no-34% SiO2 onesihlabathi se-zircon ngaphakathi, futhi i-zirconia corundum firebrick ithululelwa esikhunjeni ngemva kokuncibilika esithandweni somlilo sikagesi. Isitini somlilo se-zirconia corundum siyingxenye ye-acid refractory enezici ezihlukahlukene zamandla aphezulu wemishini, ukumelana nokushaqeka okuhle kokushisa, ukuqina okuphezulu ngaphansi komthwalo, ukumelana nokuguguleka okuqinile kanye nokuminyana okuphezulu nokunye. isithando somlilo esihlanzekile sensimbi, isithando somlilo esincibilikisa insimbi esingeyona ayoni nokunye.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-zircon corundum block ikhiqizwa ngesihlabathi se-zircon esizinzile kanye nokuqukethwe kwe-zircon engaphezu kuka-64%. I-zircon corundum fire block ithululelwa esikhunjeni ngemuva kokuncibilika esithandweni sokuncibilika sikagesi. isakhiwo se-lithofacies siqukethe izigaba ze-eutectoid nengilazi ze-corundum ne-zirconium plagioclase. I-zircon corundum refractory block petrographic structure yenziwe nge-eutectoid nengilazi isigaba se-corundum ne-zirconium clinopyroxene. I-zircon corundum blocks inezici zamandla aphezulu wemishini, ukumelana nokushaqeka okuhle kokushisa, ukuqina okuphezulu ngaphansi komthwalo, ukumelana nokuguguleka okuqinile kanye nokuminyana okuphezulu.

Izakhiwo zeZirconia Corundum Brick

  • I-refractoriness ephezulu ngaphansi komthwalo,
  • Ukumelana nokushaqeka okuhle kakhulu kwe-thermal,
  • Ukumelana nokugqwala okuhle,
  • Amandla emishini aphezulu,
  • Ukumelana okukhulu kwe-creep,
  • Ukuminyana okuphezulu.

I-Zirconia Corundum Brick Manufacturing Process

Isitini se-Zirconia corundum sithanda ukulinganisa kwesanti ye-zircon engu-1:1 kanye nempushana ye-alumina yezimboni bese wengeza ivolumu embalwa ye-NaZO, i-ejenti ye-B20 yokuhlanganisa ngemva kokuxutshwa kahle ngokuncibilika nokuthululelwa esikhunjeni ekushiseni okuphezulu kuka-1900 ~ 2000 ℃ okuholela ekutheni isitini esihlanganisiwe esiqukethe 33 % Okuqukethwe kwe-ZrO2. Esisekelweni, sebenzisa ingxenye yesihlabathi se-zircon yokwenza i-desilicication njengento eluhlaza ukuze wenze isitini esihlanganisiwe esinokuqukethwe okungu-36%~41% kwe-ZrO2.

Ukuhlukaniswa kweZirconia Corundum Brick

I-AZS-33
I-AZS33 zirconia corundum isitini esiminyene se-microstructure yenza ingilazi imelane nokuguguleka kwengilazi ukusebenza kungabi lula ukukhiqiza amatshe noma okunye ukukhubazeka, futhi amathuba okukhiqiza amabhamuza amancane egesi aphansi kakhulu.

I-AZS-36
Ngaphezu kwe-eutectic efanayo ne-AZS-33 zirconia corundum firebrick, isitini se-AZS-36 zirconia corundum ngenxa yokwengezwa kwamakristalu e-zirconia afana neketango, nokuqukethwe kwengilazi kwehlile.

I-AZS-41
I-AZS-41 i-zirconia corundum isitini somlilo iqukethe ukusatshalaliswa okufanayo kwamakristalu e-zirconia, ochungechungeni lwe-zirconia corundum, ukumelana nokuguguleka kwayo kungcono kakhulu.

Ukusetshenziswa kweZirconia Corundum Brick

Amabhulokhi eZircon corundum asetshenziswa kakhulu esithandweni sezimboni sengilazi, isithando somlilo sikagesi sengilazi, imboni ye-slideway yensimbi nensimbi, isithando somlilo sezimboni se-sodium metasilicate sokumelana nokuguguleka kwamakhemikhali nokwemishini ekushiseni okuphezulu.
