Kub thiab txias dov coil ua lag luam xyoo no yog qhov pom tseeb ntawm "tsis txawv txav", feem ntau cuam tshuam nrog tus nqi poob siab, tshwj xeeb tshaj yog nyob rau lub Tsib Hlis xyoo no, tus nqi tau nce siab.Thaum Lub Kaum Ib Hlis, kub thiab txias dov coil lag luam ib zaug ntxiv rau hauv kev lag luam turbulent.
Ua ntej, nws yog ib qho nyuaj rau nce qhov kev siv ntawm kev thov.Niaj hnub no, lub tsheb lag luam tsis muaj zog, chip shortage teeb meem tseem muaj, ntau lawm thiab muag khoom poob.Cov khoom siv hauv tsev ua lag luam tsim khoom thiab muag khoom yog qhov tsis zoo.Txawm hais tias kev lag luam vaj tse feem ntau yog kev siv cov khoom siv hlau xws li rebar steel, tab sis qhov tsis muaj zog ntawm kev lag luam vaj tsev tsis ncaj qha cuam tshuam rau kev noj cov khoom siv hauv tsev.
Thaum kawg ntawm lub sijhawm no, vaj tse, tsheb, khoom siv hauv tsev thiab lwm yam kev lag luam hauv qab yog qhov nyuaj los txhim kho qhov tseem ceeb, qhov kev siv ntawm cov cua txias thiab kub dov coil xav tau tsuas yog tsis muaj zog yuav tsis muaj zog.
Qhov thib ob, cov khoom yuav tsis nce ntau.Tam sim no, qee lub tuam txhab steel vim lub caij cua sov hauv cheeb tsam ib puag ncig tiv thaiv kev txwv kev tsim khoom thiab kev siv ntawm cov khoom siv tawm.Ntau lub tuam txhab steel nyob rau lub sijhawm no txhawm rau nce kev txwv ntau lawm, kev txiav ntau lawm, kom ntseeg tau tias xyoo no cov khoom siv hlau tsis zoo tshaj li xyoo tas los.Li Zhongshuang cia siab tias qhov kawg ntawm lub xyoo no mus txog rau thaum pib ntawm lub xyoo tom ntej no lub sij hawm ntawm lub sij hawm, crude steel ntau lawm yuav poob mus ntxiv, cov khoom lag luam yuav tsis nce yuav tsuas yog txo.
Thib peb, cov nqi tsim khoom ntawm kub thiab txias dov coil phaj yuav tsum txo qis.Tsis ntev los no, cov nqi ntawm cov hlau ore, coke, seem thiab lwm yam raw steel roj tau poob, thiab tus nqi ntawm cov hlau ore imported tau poob ntau dua 60%.Cov nqi hlau ore tseem muaj qee qhov chaw poob rau yav tom ntej.Tsis tas li ntawd, kev txheeb cais qhia tau hais tias nyob rau lub lim tiam dhau los ntawm lub Kaum Ib Hlis, cov khoom seem steel kuj poob ntau dua 10 feem pua.
Hlau thiab steel raw roj nqi poob, ua rau cov tuam txhab steel tsim cov nqi nruab nrab ntawm lub ntiajteb txawj nqus downward, nruj nqi txhawb steel nqi nce ntawm lub zog tsis muaj zog.Kev cuam tshuam los ntawm qhov no, steel tuam txhab feem ntau kho steel Hoobkas nqi, qhov yooj yim kom txo tau lub ntsiab.Qhov no tseem ua rau lub sijhawm no ntawm kub thiab txias dov coil ua lag luam tus nqi poob qis ib qho ntawm cov laj thawj.
