Classification ntawm cov ntaub ntawv refractory

Muaj ntau ntau yam ntawm cov ntaub ntawv refractory 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 ntxhia muaj pes tsawg leeg, kev faib cov txheej txheem tsim khoom, thiab kev faib cov ntaub ntawv.

1. Raws li qib ntawm refractoriness:

Ordinary refractory khoom: 1580 degree -1770 degree

Advanced refractory khoom: 1770 degree -2000 degree

Super grade refractory material: >2000 degree

2. Raws li cov duab sib txawv thiab qhov ntau thiab tsawg ntawm cov khoom:

Standard hom: 230mm × 114mm × 65mm;

Tsis pub ntau tshaj 4 ntsuas ntsuas, (qhov loj me) Max: Min<4:1;

Cov duab tshwj xeeb: tsis pub ntau tshaj 2 concave fab, (loj piv) Max: Min<6:1;

Los yog muaj lub kaum sab xis ntawm 50 txog 70 degree;

Idiotype: (loj piv) Max: Min<8:1;

los yog tsis ntau tshaj 4 concave kaum; los yog lub kaum sab xis ntawm 30 txog 50 degree;

Cov khoom tshwj xeeb: crucibles, tais diav, raj, thiab lwm yam.

3. Raws li txoj kev tsim khoom, cov khoom siv refractory tuaj yeem muab faib ua:

Cov khoom siv hluav taws xob, cov khoom siv hluav taws xob tsis zoo, cov khoom siv hluav taws xob tsis zoo

4. Kev faib tawm los ntawm cov khoom siv tshuaj lom neeg ntawm cov ntaub ntawv:

Acid refractory, nruab nrab refractory, yooj yim refractory

5. Kev faib tawm los ntawm 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 tshawb fawb, thiab muaj qhov tseem ceeb ntawm kev siv qhov tseem ceeb.
