- Kev Tswj Xyuas Kev Siv Hluav Taws Xob: Txhua tuj ntawm cov khoom siv 8,000 kWh, nrog rau hluav taws xob suav txog ntau dua 60% ntawm cov nqi. Kev ua kom qhov kub ntawm lub cub tawg zoo tshaj plaws (piv txwv li, tswj ≥2800 ° C) txo qhov kev siv hluav taws xob ntawm ib chav.
Kev Noj Zaub Mov Txawj Ntse
- 5G + AI Kev Saib Xyuas Lub Sijhawm Tiag: Cov sensors taug qab cov khoom siv hluav taws xob ntawm hlau, ua ke nrog cov qauv kwv yees sib npaug ntawm cov pa roj carbon kom suav cov nqi ntxiv ntawm carburizer kom meej.
- Kev Pub Noj Qib Tes Robot:
- Cov khoom me me (3–5 hli) rau kev ua kom muaj zog tas mus li.
- Cov hmoov zoo (<1 hli) rau kev hloov kho cov pa roj carbon sai, txo qhov kev poob oxidation.
III. Kev koom ua ke ntawm Cov Txuj Ci Ua Hlau Uas Muaj Carbon Tsawg
EAF Kev Tsim Khoom Ntsuab
- Kev Rov Qab Los Ntawm Cov Kub Pov Tseg: Siv cov pa roj kub siab rau kev tsim hluav taws xob, txuag hluav taws xob thiab txo cov pa CO₂ tsis ncaj qha.
- Kev Hloov Coke: Hloov cov coke ib nrab nrog cov roj av coke uas muaj graphitized, txo kev siv roj av fossil uas tsis rov ua dua tshiab.
- Kev Ua Ntej Ua Kub Rau Cov Khoom Pov Tseg: Ua kom luv lub voj voog ua kom yaj, txo qis kev siv hluav taws xob, thiab ua raws li cov qauv EAF "ze li xoom carbon".
Kev Sib Koom Tes Ua Hlau Raws Li Hydrogen
- Kev Txhaj Tshuaj Hydrogen Los Ntawm Lub Cub Hluav Taws Xob: Kev tshuab cov pa roj uas muaj hydrogen ntau (piv txwv li, H₂, roj av) hloov cov coke ib nrab, txo cov pa roj carbon.
- Kev Txo Nqi Ncaj Qha Rau Lub Cub Hydrogen Ncej: Siv hydrogen ua ib qho tshuaj txo rau kev txo cov hlau ncaj qha, txo cov pa phem los ntawm >60% piv rau cov cub tawg ib txwm muaj.
IV. Kev Tswj Xyuas Zoo: Kev Tshawb Xyuas Tag Nrho Cov Txheej Txheem thiab Kev Tshuaj Xyuas
Kev taug qab cov khoom siv raw Blockchain
Kev luam theej QR code muab kev nkag mus rau cov ntawv tshaj tawm kev lis kev cai, cov yeeb yaj kiab kuaj sulfur, thiab cov ntaub ntawv ntau lawm, kom ntseeg tau tias ua raws li txoj cai.
Kev Tshuaj Xyuas Lub Tshuab Microscope Hluav Taws Xob
Cov neeg tshuaj xyuas zoo kho qhov ceev ntawm cov khoom siv crystalline los ntawm kev siv lub tshuab hluav taws xob microscopy, tshem tawm cov khoom suav nrog silica-alumina kom tiv thaiv kev raug mob hauv cov khoom siv castings zoo li cov hlau nuclear valve.
V. Cov Xwm Txheej thiab Cov Txiaj Ntsig ntawm Daim Ntawv Thov
