Siab alumina tshwj xeeb zoo li tus cib

Cov cib ua kom zoo nkauj tshwj xeeb tuaj yeem tiv taus ntau yam kev hloov pauv ntawm lub cev thiab tshuaj lom neeg thiab kev ua haujlwm ntawm qhov kub thiab txias. Qhov tshwj xeeb zoo li tus cib ua hluav taws xob yog cov khoom siv hluav taws xob uas muaj qhov zoo thiab qhov loj me.

Cov cib hluav taws xob tshwj xeeb tuaj yeem muab faib ua cov cib uas raug rho tawm, cov cib tsis ua haujlwm, cov cib fused (fused nrum cib), thiab cov nplaim hluav taws kub thiab rwb thaiv tsev raws li txheej txheem npaj. Tsis tas li ntawd, tshwj xeeb-zoo li cov cib ua hluav taws xob tuaj yeem faib ua cov txheej txheem cib, cov cib zoo tib yam, thiab cov duab ua cov cib raws li lawv cov duab thiab qhov loj me. Cov cib ua hluav taws kub tshwj xeeb tuaj yeem siv ua cov khoom kub hauv tsev thiab cov khoom siv tsim ua lub tsev kilns thiab ntau yam khoom siv cua sov.

Tus nqi tshwj xeeb zoo li tus cib refractory cib nyob ntawm qhov nyuaj ntawm txheej txheem txheej txheem thiab cov khoom siv ntawm cov cib ua hluav taws kub. Feem ntau, cov chaw tsim khoom siv hluav taws xob yuav nug tus neeg yuav khoom los muab cov duab cib qub thaum hais txog qhov tshwj xeeb zoo li tus cib hluav taws kub nyhiab. Koj yuav tsum paub txhua lub kaum sab xis, txhua lub radian lossis Cov tuab, ntev, qhov siab, thiab lwm yam ntawm txhua daim duab. Yog li ntawd, thaum koj xav tau nug txog tus nqi ntawm cov cib tsim tshwj xeeb, thov muab cov duab ntxaws ntxaws lossis lwm yam ntaub ntawv cuam tshuam, yog li peb tuaj yeem nrawm thiab raug xam tus nqi ntawm cov cib tshwj xeeb zoo li cov nplaim hluav taws rau koj.

1. Refractoriness: Refractoriness yog cov cuab yeej ntawm cov cib refractory uas tuaj yeem tiv taus qhov kub tsis kub yaj thaum siv, thiab yog ib qho tseem ceeb ntsuas rau ntsuas qhov zoo. Yog tias qhov refractoriness tsis siab, ntau cov kua theem yuav tsim tawm hauv cov cib vim yog qhov kub thiab txias mus sij hawm ntev thaum siv, uas yuav ua rau tag nrho cov masonry puas los ntawm yaj. Cov qib ntawm refractoriness nyob ntawm cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov khoom siv raw, qhov sib xyaw ua ke ntawm cov khoom siv raw, thiab viscosity ntawm cov kua theem.

2. Thauj khoom kub ua kom sov: Lub ntsuas kub ua kom sov muaj feem cuam tshuam nrog lub zog ntawm lub qhov cub ntawm qhov kub. Feem ntau, nws tau qhia los ntawm qhov kub ntawm qee qhov kev hloov pauv uas tshwm sim los ntawm cov cib ua hluav taws xob nyob hauv qhov hnyav li ntawm 2 kilograms ib square centimeter. Cov iav theem yog qhov me me, cov crystallization tsim cov qauv network thiab cov cib nrog qhov porosity qis, thiab qhov hnyav ua kom sov siab dua.

3. Lub zog sib zog ntawm chav sov: qhia txog lub zog ntawm cov cib hluav taws xob thiab lub peev xwm los nqa cov khoom zoo li qub: nws muaj kev sib raug zoo nrog cov cib ua haujlwm tsis zoo rau kev cuam tshuam thiab txhuam. Lub zog sib zog nyob ntawm qhov tseem ceeb xws li qhov ntom ntom ntawm cov khoom, qhov muaj pes tsawg leeg ntawm cov khoom siv raw thiab qib ntawm sintering.

4. Porosity: Porosity muaj kev sib raug zoo nrog slag yaig tsis kam. Slag yaig tsis kam feem ntau yog nyob ntawm cov khoom siv tshuaj lom neeg (cov kua qaub, alkaline, nruab nrab). Cov av nplaum cib yog ib nrab cov khoom siv kua qaub. Ua kom cov ntsiab lus ntawm AL2O3 tuaj yeem ua rau kev txhim kho corrosion tsis haum rau cov kua qaub thiab alkaline slag. Cov khoom siv nrog cov khoom siv tshuaj zoo ib yam yuav ua rau thaj chaw sib cuag ntawm cov cib thiab cov xuab zeb yaj vim qhov ntxeem tau loj, yog li cov molt slag nkag mus rau hauv lub cev cib los ntawm qhov hws, thiab cov slag tiv taus kuj raug txo kom tsawg. Qhov porosity nyob ntawm yam xws li cov khoom sib xyaw ua ke ntawm cov pellets, qhov ntom ntom ntom ntom ntom thiab qib kev ua txhaum ntawm cov khoom qub.

5. Cov kab seem seem: qhov ntim ntim ntawm cov khoom siv hluav taws xob ntawm qhov kub siab thaum cov kab uas seem me me Vim yog lub cua sov ntev ntawm cov cib thaum siv, cov cib tau sintered ntxiv, thiab qhov ntim me me, ua rau tawg thiab deformation ntawm lub cev rauv. Yuav kom txo qis qhov seem me me, cov khoom yuav tsum raug rho tawm ntawm qhov kub txaus.
