3, Cov yam ntxwv ntawm Dense High Chrome Brick:
1) High ceev, lub zog> 100MPa, porosity <18%. Yog li ntawd, cov khoom muaj zoo hnav tsis kam.
2) Zoo acid thiab alkali tsis kam thiab slag kuj.
3).Nws muaj kev ruaj ntseg zoo ntawm qhov kub thiab txias me me ntawm cov kab rov ua dua.1600 degree * 3h Tsawg dua lossis sib npaug li 0.2%

Lub ntsiab tivthaiv ntawm compact chrome oxide cib yog Cr2O3, uas feem ntau yog ntau tshaj 90%. Cov khoom yog nyuaj rau sinter, yog li nws yog tsim nyog los qhia sintering additive TiO2 thiab ib tug me me ZrO2, Lub ntsiab yog vim li cas rau nws daim ntawv thov nyob rau hauv lub siab yaig cheeb tsam ntawm molten iav yog raws li nram no: 1) solubility ntawm Cr2O3 yog tsawg heev. ; 2) lub kaum sab xis ntawm Cr2O3 sinter thiab molten iav yog loj thiab lub wettability tsis zoo; 3) viscosity ntawm molten slag yog nce nyob rau hauv lub slag ntawm Cr2O3 dissolving tus neeg sawv cev, uas yog hu ua txheej tiv thaiv ntawm firebrick thiab zoo txo tus nqi yaig.
Qhov sib ntxiv ntawm TiO2 tuaj yeem txhawb nqa sintering ntawm Cr2O3 khoom. Tib lub sijhawm, TiO2 muaj kev sib raug zoo nrog alkali dawb iav, thiab yuav tsis tsim pob zeb lossis npuas, thiab yuav tsis cuam tshuam rau kev ua haujlwm tas li ntawm lub tank kiln. Yog li ntawd, nyob rau hauv zus tau tej cov Cr2O3 compact khoom, ntxiv TiO2 sintering pab thiab 3-4% boron feem ntau yog siv los tsim ntau titanium chromium tebchaw. Ntxiv ZrO2 hmoov tuaj yeem txhim kho cov thermal poob siab. Qhov no yog raws li qhov sib txawv ntawm thermal expansion coefficient ntawm ZrO2 thiab Cr2O3 thiab lub hauv paus ntsiab lus ntawm theem transformation toughening, uas ua rau cov khoom tsim microcracks nyob rau hauv cov txheej txheem ntawm cua sov thiab txias, tiv thaiv cov khoom los ntawm cracking vim thermal stress thiab mechanical stress, thiab plays lub luag hauj lwm ntawm buffering kev nyuaj siab. Nyob rau tib lub sijhawm, qhov sib ntxiv ntawm ZrO2 kuj tseem ua lub luag haujlwm hauv kev txhawb nqa sintering

5.Cov lus pom zoo ntawm cov khoom siv tau zoo, cov khoom tau raug xa tawm mus rau Kaus Lim Qab Teb, Australia, Kenya,
6.Cov chaw tsim khoom yog cov chaw tsim khoom lag luam thiab tuaj yeem muab cov khoom lag luam ua tiav cov ntaub ntawv ntsuam xyuas lossis cov ntaub ntawv xeem thib peb.
