Yuav hloov li cas refractory cib hauv kev kho cov khoom tooj liab

Lub tshuab ua kom rov ua dua tshiab yog qhov tsim nyog rau kev kho kom zoo nkauj tooj liab tooj liab, thiab cov khoom siv khib nyiab khib nyiab rau kev saib xyuas thiab hloov pauv feem ntau yog pov tseg magnesia chrome cib thiab pov tseg cov av nplaum av. Thaum yaj cov tooj liab, tsuas yog 20% ​​txog 25% cov khoom siv tau tso cai ntxiv. Nws qhov zoo yog qhov cua sov poob qis poob, kaw zoo, thiab txhim kho kev ua haujlwm ib puag ncig; txo lub sijhawm saib xyuas, txo qis kev tshem tawm thiab hloov cov khib nyiab cib hluav taws xob; ua haujlwm tau yooj yim, txuag cov neeg ua haujlwm, thiab siv zog ua haujlwm tsawg. Qhov tsis zoo yog qhov peev txheej peev txheej siab. Cov hauv qab no qhia txog cov laj thawj vim li cas lub tshuab ua kom rov ua dua tshiab yuav tsum tau hloov kho ntau zaus thiab cov cib cib refractory pov tseg tau hloov pauv.

1. Cov cua sov kub ntawm lub tshuab ua kom rov ua dua tshiab yog siab dua 1350 ℃ (lub sijhawm pov tseg), thiab qhov kub siab tuaj yeem ncav cuag 1450 ℃ (lub sijhawm oxidation). Vim tias lub tshuab ua kom sov lub cev tig, tsis muaj cov pas dej ua ke sib xyaw ua ke slag kab hauv lub cub tawg, thiab cov slag yuav xeb thiab yaj. Kev yaig ntawm cov hlau yuav luag cuam tshuam nrog ntau dua 2/3 ntawm sab hauv ntawm lub tshuab ua cua sov, thiab poob ntawm cov cib ua hluav taws xob hauv qhov ua haujlwm no yog qhov loj, uas yuav tsum tau siv sijhawm ib ntus los tshuaj xyuas thiab kho, thiab ntau qhov tawg pov tseg cov nplaim hluav taws yuav tsum tau muab tshem tawm thiab hloov.

2. Vim muaj kev sib hloov ntau zaus ntawm lub cev rauv, yuav tsum tau tshuaj xyuas thiab kho lub sijhawm. Cov khoom siv khib nyiab tawg uas raug puas tsuaj yuav tsum tau muab tshem tawm thiab hloov pauv, yog li cov masonry thiab cov hlau rauv lub plhaub raug kaw kom ze rau qhov ua kom muaj kev sib txhuam ntawm cov masonry thiab lub plhaub hlau rauv. Lub tshuab cua sov lub plhaub tig ua ke kom muaj kev ruaj ntseg ntawm cov masonry.
