Thaum lub sij hawm yaj melting, vim {- Cov khoom sib xyaw ntawm cov kab ke ntawm cov kab cig, mus rau ntawm cov khoom tawg, tsis muaj pa tsis zoo rau huab cua thiab ignites tsis zoo. Vim li no, nws yog ib qho tsim nyog los ntxig breathable qhov, uas yog, ib puag ncig hlau yog muab tso rau hauv ib feem ntawm cov ntaub uas tsis yog airtight. Tsis txhob qhib nws. Cias xoob tus nqi thiab rub tawm cov pa hluav taws. Txoj kev no feem ntau siv nyob rau hauv ferrosilicon smelting kom muaj kev ua pa.
Qhov twg uas muaj qhov muag cua yuav tsum tau nkaug:
1. Qhov qis ntawm lub cev vertebral lossis thaj tsam loj ntawm cov khoom muaj huab cua tsis zoo.
2. Tom ncig ntawm qhov chaw taws.
Tho qhov muag qhib lub qhov muag tso cai rau koj kom ua tiav cov hom phiaj hauv qab no:
1. Ua ib qho ntau ntawm cov pa roj carbon monoxide tau tsim tawm tom qab cov tshuaj tiv thaiv kev ua kom sai, tab sis kuj tseem ua kom muaj cov cua sov ua kom zoo nkauj, thiab ua kom nrawm dua cov tshuaj lom neeg hauv lub cub tawg.
2. Txo qhov tshwm sim ntawm qhov tshwm sim ntawm kev tiv thaiv thiab txo qis kub.
