Yav tom ntej steel poob thiab sawv dua, lub zog ntawm kev lag luam xav tau npaum li cas?

Nyob rau yav tom ntej, kev ua lag luam tau rov qab los rau qee qhov, tab sis qhov chaw ua lag luam tam sim no kuj yog lub teeb, uas zoo li me ntsis deserted tag nrho. Raws li rau lub tswv yim ntawm kev cia lub caij ntuj no, cov tub lag luam feem ntau tau qhia tias lawv tseem yuav tos txog qhov xwm txheej tshwj xeeb ua ntej kev txiav txim siab, tab sis qhov tseeb tias qhov kev cia siab ntawm lub caij ntuj no tsis muaj zog heev, tab sis tam sim no cov tub lag luam cov khoom muag tsis loj. poob siab. Yog li cas tus nqi hlau yuav mus tag kis?

Nag hmo yav tom ntej hloov pauv, qhov chaw tus nqi yog qhov ruaj khov, qee qhov poob me ntsis, kev lag luam kev lag luam yog qhov qub, thiab cov tub lag luam kev xav tau txais. Nyob rau theem no, steel mills tau txo qis kev tsim khoom thiab kev xa khoom, kev lag luam kev lag luam luv luv, qee qhov kev qhia tshwj xeeb yog tawm ntawm cov khoom lag luam, thiab cov kev xav tau raws caij nyoog tsis muaj zog. Txawm li cas los xij, txiav txim siab tias cov khoom muag tam sim no tsawg, thiab qhov sib txawv ntawm cov khoom siv raw khoom muaj zog txhawb rau qhov chaw, nws xav tias tus nqi hlau yuav ruaj khov rau tag kis. Qhov nruab nrab ib feem yog nce, nrog rau qhov ntau ntawm 10-30.
