Kev lag luam steel yog ib qho kev lag luam yooj yim ntawm kuv lub teb chaws kev lag luam hauv lub teb chaws thiab tuav txoj haujlwm tseem ceeb hauv kuv lub teb chaws kev lag luam thiab kev tsim kho hauv teb chaws. Rau kev lag luam steel, nws cov txheej txheem tsim khoom yog kev lag luam uas muaj kev pheej hmoo siab nrog cov yam ntxwv txaus ntshai xws li kub thiab kub siab, nplaim hluav taws kub thiab tawg, muaj kuab lom thiab muaj kev phom sij. Nrog rau kev txhim kho ntawm kev lag luam steel, qee qhov kev nyab xeeb kev nyab xeeb tau tshwm sim. Yog li ntawd, nws yog ib qho tseem ceeb tshwj xeeb los xyuas kom muaj kev nyab xeeb ntawm kev tsim khoom thiab lub neej thiab kev noj qab haus huv ntawm cov neeg ua haujlwm tsim khoom.
1.Hauv cov txheej txheem steel thiab metallurgical, ntau yam teeb meem kev nyab xeeb tshwm sim vim yog cov neeg ua haujlwm thiab cov khoom siv. Nws yog ib qho tseem ceeb tshwj xeeb uas yuav tsum ua kom muaj kev nyab xeeb thiab siv tau zoo los txo qhov tshwm sim ntawm kev raug mob. Cov teeb meem kev nyab xeeb hauv kev lag luam steel yog:
(1) Cov nplaim hluav taws kub hnyiab hauv kev tsim khoom;
(2) Cov concentration ntau dhau ntawm cov pa phem thiab cov pa phem hauv kev tsim khoom;
(3) zais qhov phom sij ntawm qhov kub thiab txias thiab cov cuab yeej siv siab;
(4) Teeb meem nrog kev laus ntawm cov khoom siv hluav taws xob;
(5) Gas to hauv cov txheej txheem ntau lawm, thiab lwm yam.
2.Ntaus phom ntawm steel nroj tsuag
(1). Cov pa roj carbon monoxide
Feem ntau, thaum cov pa roj carbon monoxide nyob hauv huab cua nce mus txog 5% -10%, nws tuaj yeem ua rau cov pa roj carbon monoxide lom. Tom qab cov pa roj carbon monoxide nkag mus rau tib neeg lub cev, nws yuav ua ke nrog hemoglobin hauv cov ntshav, thiab tom qab ntawd tus naj npawb ntawm hemoglobin tuaj yeem ua ke nrog cov pa oxygen yuav txo qis, ua rau hypoxia hauv cov ntaub so ntswg thiab ua rau tuag taus.
(2). Cov pa roj carbon dioxide
Qhov teeb meem tseem ceeb ntawm cov pa roj carbon dioxide rau tib neeg lub cev yog los txhawb lub chaw ua pa ntawm tib neeg lub cev, ua rau ua tsis taus pa, nce pa luam yeeb, thiab mob taub hau, tsis meej pem thiab lwm yam tsos mob.
(3). Nitrogen oxides
Nitrogen oxides xa mus rau cov tebchaw uas muaj ob lub ntsiab lus, nitrogen thiab oxygen. Feem ntau cov nitrogen oxides muaj xws li nitric oxide (NO, tsis muaj xim), nitrogen dioxide (NO2, reddish xim av), nitrous oxide (N2O), thiab dinitrogen pentoxide (N2O5). Tsuas yog rau dinitrogen pentoxide, uas yog cov khoom nyob rau hauv ib txwm muaj, lwm cov nitrogen oxides yog gaseous nyob rau hauv ib txwm muaj mob. Nitrogen oxides (NOx) raws li cov pa phem feem ntau xa mus rau NO thiab NO2.
(4). Sulfur dioxide
Sulfur dioxide (tshuaj formula SO2) yog cov feem ntau, yooj yim, thiab feem ntau irritating sulfur oxide. Sulfur dioxide concentrations saum toj no 0.5ppm nyob rau hauv cov huab cua muaj peev xwm cuam tshuam rau tib neeg lub cev; ntawm 1 ~ 3ppm, feem ntau cov neeg pib khaus khaus; ntawm 400~500ppm, tib neeg yuav tsim rwj thiab pulmonary edema mus txog thaum lawv tuag taus. Sulfur dioxide muaj cov nyhuv synergistic nrog cov pa luam yeeb hauv qhov chaw. Thaum cov sulfur dioxide concentration nyob rau hauv cov huab cua yog 0.21ppm thiab cov pa luam yeeb concentration ntau dua 0.3mg / L, qhov tshwm sim ntawm cov kab mob ua pa tuaj yeem nce ntxiv thiab cov mob ntawm cov neeg mob uas muaj kab mob ntev tuaj yeem deteriorate sai.
Hauv cov hlau smelting, qhov tseem ceeb tshaj plaws yog kev thauj mus los ntawm cov pa roj carbon monoxide, uas ua rau muaj cov pa phem xws li CO, H2, cov pa roj carbon monoxide, thiab cov tshuaj chlorine kom xau hauv lub rhiav, yog li ua rau cov neeg raug mob. Qhov no yuav tsum tau teeb tsa lub tswb ntsuas roj los saib xyuas cov roj concentration hauv qhov chaw ua haujlwm uas twb muaj lawm. Lub tswb roj teeb uas tsim los ntawm peb lub tuam txhab tuaj yeem kuaj xyuas cov roj concentration ntawm qhov chaw, thiab muaj lub suab nrov thiab lub teeb ceeb toom, txhawm rau tua cov phom sij kev nyab xeeb nyob rau hauv thawj qhov ntau, xyuas kom meej tias cov pa phem uas tsim los ntawm kev cob qhia ntau lawm nyob rau hauv cov qauv kev nyab xeeb, thiab upload cov ntaub ntawv sau los ntawm lub tswb mus rau lub computer tswj los ntawm lub computer sab sauv software kom paub lub centralized tswj ntawm on-site ntau lawm.
