Tuam Tshoj tau tsim ib txoj kev ua hlau tshiab uas txhawb nqa cov khoom tsim tau los ntawm 3,600 npaug.

Cov kws tshawb fawb hais tias txoj kev tuaj yeem ua tiav cov txheej txheem ua hlau hauv tsuas yog peb mus rau rau vib nas this, piv rau tsib mus rau rau teev uas yuav tsum tau ua los ntawm cov tsoos blast furnaces.

Lub tshuab ua hlau tshiab tsim nyob rau hauv Suav teb tau tsim los cuam tshuam rau kev lag luam steel thoob ntiaj teb. Tsim los tom qab ntau tshaj 10 xyoo ntawm kev tshawb fawb, txoj kev no txhaj cov hmoov av hlau ore hmoov rau hauv lub qhov cub kub heev, ua rau "cov tshuaj tiv thaiv tawg", raws li cov engineers. Qhov tshwm sim yog ib qho kev nruam ntawm high-purity hlau uas tsim raws li lub teeb liab, ci cov kua dej uas sib sau ua ke ntawm lub hauv paus ntawm lub cub tawg, npaj rau kev ncaj qha los yog ib-kauj ruam steel-ua.
Cov txheej txheem tsuas yog siv peb mus rau rau vib nas this.
Txoj kev ua hlau flash, raws li tau piav qhia los ntawm tus xibfwb Zhang Wenhai thiab nws pab neeg hauv ib daim ntawv luam tawm hauv phau ntawv xov xwm uas tsis yog hlau tshuaj xyuas lub hli dhau los, tuaj yeem ua tiav cov txheej txheem ua hlau hauv tsuas yog peb mus rau rau vib nas this, piv rau tsib mus rau rau 6 teev yuav tsum tau los ntawm cov tsoos blast furnaces.
Qhov no sawv cev rau 3,600-fold lossis ntau dua hauv kev nrawm. Txoj kev tshiab kuj ua tau zoo tshwj xeeb nrog qis lossis nruab nrab-yield ores, uas muaj ntau hauv Suav teb, raws li cov kws tshawb fawb, South China Morning Post tau tshaj tawm.
Tuam Tshoj tam sim no cia siab rau cov txiaj ntsig tau zoo thiab siv nyiaj ntau los ntawm Australia, Brazil, thiab Africa. Raws li Zhang thiab nws cov npoj yaig, cov thev naus laus zis tshiab tuaj yeem txhim kho kev siv hluav taws xob hauv Tuam Tshoj txoj kev lag luam steel los ntawm ntau tshaj ib feem peb. Tsis tas li ntawd, tshem tawm qhov xav tau ntawm cov thee yuav pab cov kev lag luam steel ua tiav lub hom phiaj ntawm zero carbon dioxide emissions.
Blast furnace reliance hampers lub hom phiaj.
Tuam Tshoj lub peev xwm tsim khoom steel twb dhau los ntawm kev sib xyaw ua ke ntawm cov khoom siv thoob ntiaj teb, muab nws qhov txiaj ntsig zoo hauv kev lag luam tseem ceeb xws li kev kub ceev tsheb ciav hlau, nkoj tsim, thiab kev tsim tsheb.
Ib qho ntawm cov kev sib tw loj tshaj plaws rau kev tsim cov hlau nplaum yog cov ore-txhaj tshuaj lance, uas yuav tsum tau ua kom cov hlau ore nyob rau hauv qhov kub thiab txias, txo qis ntauwd nrog thaj chaw loj tshwj xeeb los pib cov tshuaj tiv thaiv tsim nyog.
Zhang pab neeg tau tsim lub vortex lance uas tuaj yeem txhaj 450 tonnes ntawm hlau ore hais ib teev. Lub reactor nruab nrog peb lub lances tsim 7.11 lab tonnes ntawm hlau txhua xyoo. Raws li daim ntawv, lub lance "tau nkag mus rau kev lag luam ntau lawm."
