Zoo li siab alumina cib

Cov khoom lag luam zoo: siab refractoriness thiab ntsaws qhov kub thiab txias, nrog kev nce ntawm Al2O3 cov ntsiab lus, slag tsis kam ua haujlwm tau zoo dua qub.

Daim ntawv thov khoom: Feem ntau yog siv rau sab hauv ntawm lub qhov cub tawg, lub qhov cub tawg tawg, hluav taws kub saum lub qhov cub, lub qhov cub tawg, lub qhov cub tawg rov qab, thiab lub qhov cub tawg. Tsis tas li ntawd, qib siab alumina cib kuj tseem siv dav ua qhib qhib lub tshuab ua kom rov zoo dua qub, cov ntsaws rau cov tshuab, cov cib nozzle, thiab lwm yam.

khoom piav qhia

Kev teeb tsa cov cib alumina siab nyob rau hauv lub cub tawg yog qhov thev naus laus zis tseem ceeb heev, tshwj xeeb tshaj yog nyob rau thaj chaw uas muaj cov txheej txheem nyuaj, kev hloov pauv loj hauv qhov nkhaus thiab cov ntu ntawm lub ru tsev rauv. Kev teeb tsa tsis zoo ntawm cov cib alumina siab tuaj yeem ua rau kub siab tshuab los yog hluav taws khiav. Cov txheej txheem cib ua hluav taws xob yuav ua rau nyuaj rau kev tsim kho. Yog li ntawd, nws yog qhov yuav tsum tau kho qhov tshwj xeeb zoo li tus cib alumina siab, uas tuaj yeem txo qhov nyuaj ntawm kev tsim kho thiab tshem tawm qhov khoob uas yuav tshwm sim vim kev tsim teeb meem thaum siv cov txheej txheem qib siab alumina. Lub neej ntawm qhov cub.

Cov duab zoo ntawm cov duab tshwj xeeb zoo li alumina cib yuav tsum ua tau raws li cov hauv qab no:

(1) Dimensional kam rau ua: siab siab ± 2%; wedge-puab nto loj thiab me taub hau dav kam rau ua ± 2mm; qhov sib txawv me me kam rau ua ± 1 hli; ntev kam rau ua ± 1%. Custom-made high alumina bricks, qhov txawv yog 2 hli.

(2) Ntug poob. Tso cai rau sab kub lossis txias kom muaj ob sab puas txog 40 hli ntev thiab 5 hli tob; tab sis tsis pub tshaj.

(3) Angular poob. Tsuas muaj ib lub ces kaum puas rau kev tsim ua cov av alumina siab rau ntawm qhov kub thiab txias, thiab tag nrho qhov ntev ntawm peb sab ntawm kaum kev puas tsuaj yuav tsum tsis pub tshaj 50 hli. Lub kaum sab xis tsis tshaj 20mm tsis suav nrog.

(4) Kev tawg. Lub cib nto tau tso cai kom muaj cov plaub hau zoo li cov kab nrib pleb; tsis pub cov kab nrib pleb mus rau qhov chaw hnav tau tso cai; lwm qhov tawg tsis ntev tshaj 40 hli thiab tsis dav dua 0.2 hli raug tso cai.

(5) Cov qhov, cov cim melting thiab bulges. Cov qhov tso cai thiab cov cim yaj yog 10 hli txoj kab uas hla thiab 10 hli tob; bulge yog 0.5 hli. Cov cib alumina siab nrog ntau cov npoo ntxhib hauv ib pawg ntawm cov cib yuav tsum tsis pub tshaj 70% ntawm tag nrho.
