Txawm li cas los xij, lub tuam txhab nrog kev sib tw roj ntau tshaj yog 567.34kg / t.
Hauv qab no, kev faib tawm tau qhia txog qhov xwm txheej uas qee cov lag luam hlau ua kom cov roj hluav taws xob tsawg dua nyob rau thawj ib nrab xyoo 2019 (Ceeb Toom: vim muaj qhov tsis sib luag ntawm cov roj sib piv, coke ratio, thee piv thiab lwm cov ntaub ntawv tshaj tawm los ntawm qee cov lag luam, Cov lag luam hauv qab no txheeb xyuas Cov ntawv no kuj muaj qhov tsis sib xws nyob hauv cov ntaub ntawv):
Tus nqi coke thiab qhov sib piv ntawm cov roj tsawg zuj zus nyob rau tib lub sijhawm, thiab qhov xwm txheej ntawm 10 tuam txhab nrog cov roj hluav taws xob piv tau muaj nyob hauv Table 3.
Lub ntsiab tseem ceeb ntawm kev txo qis ntawm hlau-rau-roj piv yog txo tus coke piv. Tom qab nce qhov sib tov sib xyaw ua ke ntawm cov thee, nws yog qhov tsim nyog kom ua tiav qhov hloov siab ntawm cov thee hmoov tsis txhob siv coke, kom tus roj piv yuav tsis nce ntxiv. Hauv thawj ib nrab ntawm 2019, 12 ntawm cov koom ua haujlwm cov koom haum steel tau ua tiav qhov kev txo qis ntawm coke piv ntau dua qhov nce ntawm cov thee sib piv, uas ua rau txo qis ntawm cov hlau-rau-roj piv. Saib Daim Ntawv 4 rau cov lus qhia.
Qhov qis dua ntawm cov piv txwv ntawm thee yog ntau dua li qhov nce hauv coke piv, cov cua kub nce ntxiv, thiab cov roj hluav taws xob piv. Muaj 4 lub chaw ua haujlwm, raws li qhia hauv Daim Ntawv 5.
Tam sim no, thaum tus nqi sib txawv ntawm cov xim hlau sib xyaw thiab pulverized thee yog loj, lub tshuab ua kom sov ua haujlwm ntawm txoj cai ntawm Ninggang thiab lwm qhov kev lag luam muaj tseeb, txo qhov sib piv ntawm cov thee, nce cov coke piv, txhim kho cov roj permeability ntawm lub cub tawg, thiab txhawb cov foob pob hluav taws rau pem hauv ntej; Cov roj piv thiab cov nqi tsim khoom yog txo, thiab cov txheej txheem lub zog siv hluav taws xob raug txo kom tsawg.
Nyob rau hauv thawj ib nrab ntawm 2019, 24 ntawm cov koom haum steel koom nrog qhov nce nqi ntawm cov roj piv rau xyoo tas los. Cov tuam txhab muaj roj ntau dua tau txo qis los ntawm xyoo dhau los, thiab cov tuam txhab uas muaj roj hluav taws xob ntau dua yuav tsum kawm los ntawm cov tuam txhab uas muaj roj tsawg dua. Nyob rau hauv thawj ib nrab ntawm 2019, qee qhov kev lag luam nce lawv cov nqi sib piv thiab coke piv nyob rau tib lub sijhawm. Qee lub lag luam tau nce lawv cov coke piv ntau dua li cov thee piv. Qee lub chaw lag luam 'hluav taws xob roj piv ntau dua li cov coke piv, uas tsis zoo rau kom txo qis roj piv. Qhov laj thawj tseem ceeb yog vim tias cov roj qub hluav taws xob zoo dua qub, los yog cov tshuab hluav taws xob tawg tau nyob rau hauv lub xeev tsis zoo, thiab qhov sib xyaw coke yuav tsum tau nce ntxiv los tswj lub tshuab ua kom tawg. Cov tuam txhab lag luam ib leeg muaj kev saib xyuas tsis zoo ntawm cov cua sov.
