Cov khib nyiab steel slag hloov mus rau hauv cov ntaub ntawv hauv tsev

Ib hlis dhau los, ib lub tuam txhab steel nyob hauv North Craig cov qauv, nrhiav cov tshuaj muaj peev xwm hloov kho cov khoom siv hauv tsev. Raws li byproduct ntawm cov steel ntau lawm, steel slag tau ntev cov kev sib tw rau kev pab cuam tshuam vim nws txoj kev sib xyaw ua ke. Thaum tau txais txoj haujlwm, chav kuaj tam sim ntawd sib sau ua ke pawg neeg mob siab. Qeb kev txawj ntse xyoo ntawm kev txawj ntse hauv thaj chaw uas tsis muaj hluav taws xob cib tshuab, lawv pib ua cov kev sib tw.

Thaum lub sij hawm sim, cov pab pawg kws tshaj lij kev txhawb nqa thev naus laus zis ntawm cov quangong tsis tua cib tshuab. Lawv hloov kho qhov kev co, kev tsim lub siab, thiab tus txheej txheem kho tshwj xeeb rau cov yam ntxwv ntawm steel slag. Tom qab rov hais dua kev sim siab, kev ua yeeb yam zoo tshaj plaws tsim tiav: kev sib xyaw ua ke 40% cov khoom sib xyaw ua ke, ua ke nrog cov khoom sib txuam thiab cov khoom sib ntxiv. Qhov ua tiav zoo no tsim cov pob zeb sib txuas lub zog ua kom muaj zog thiab nthuav tawm cov qauv ua tau zoo heev, tag nrho ua raws li cov qauv ntawm lub tsev.

Qhov kev txhim kho zoo no tsuas yog daws cov kev sib tw ntawm cov neeg siv hluav taws xob sib tw tab sis kuj rov qab ua haujlwm tshaj plaws ntawm cov khoom siv tub rog kaum kev. Tus Quangong ZN Muv rho nyiaj tsis zoo no feem tsis siv hluav taws xob Cib Cov blocks thiab tsis-tua hluav taws xob tsim los ntawm cov khoom sib xyaw hlau tsis yog muab cov txiaj ntsig zoo tshaj plaws rau cov khoom siv hluav taws xob rau kev siv hluav taws xob hlau.
