Iikhoyili ezishushu ezigoqiweyo ziphucula inqanaba lokuqala lokuvelisa intsimbi ukuze ikwazi ukusetyenzwa ngakumbi ngamaxabiso aphezulu ngelixa iindleko ziphantsi. Ukuqengqeleka okushushu kuqala ngecwecwe lentsimbi elithi ke ligqitywe kwiperi yerola ezishushu apho ithi ixinzelelwe kwaye yolulelwe kwiikhoyili zentsimbi ezomeleleyo, eziguquguqukayo neziqinileyo.
Iikhoyili eziQithiweyo ezishushu ziguquguquka ngokwendalo kwaye zibonelela ngezibonelelo ezinkulu. Kwaye, zisetyenziswa kwiindidi ezinje ngokwenziwa ngokubanzi ukuya kuthi ga kwiiprojekthi zokwakha kunye neziseko zophuhliso. Kuba zomelele kwaye zomelele, iilori ezinomthwalo onzima ziye zaduma kwiindawo ezifana nezothutho, iziseko zophuhliso okanye ulwakhiwo apho abasebenzi kufuneka basebenze phantsi kweemeko ezinzima.
Ngaphandle kwento yokuba ziyaguquguquka, iikhoyili ezishushu ezisongiweyo ziya kuba yinto engabizi kakhulu ngokunjalo. Inkqubo yokuqengqeleka eshushu ayintsonkothanga kwaye ifuna amandla amancinci, ixesha kunye nomsebenzi kunezinye iindlela zokuqengqeleka ezibandayo. Ngenxa yolu buchule beendleko, iikhoyili ezishushu ezishushu zikhethwayo kwimveliso eninzi yeemveliso zetsimbi.
IMarike yeKhoyili eqengqelekisiweyo eshushu: Indawo enoKhuphiswano Imarike yekhoyili eqengqelekayo yindawo enokhuphiswano kunye neenkampani eziphambili ezisebenza kumgangatho wehlabathi. Ukufakwa kwefayile kwabanye abadlali ababalulekileyo, abanje ngeArcelorMittal, China Baowu Steel Group Corp co ltd,NSSMC IQELA LEPOSCO NIPPON STEEL & SUMITOMO METAL CORPORATION kunempembelelo enkulu ekukhuleni kolu shishino.
I-ArcelorMittal, oyena mvelisi mkhulu wentsimbi wehlabathi unomkhondo obalulekileyo wokwenziwa kwekhoyili eqengqelekisiweyo (HRC) enezixhobo kwiindawo ezininzi eziphambili kubandakanya i-US kunye ne-EU fracas. I-China Baowu Steel Group, eyesibini enkulu emhlabeni eyenza intsimbi ikwayenye ehamba phambili ingena phantsi kodidi lwekhoyili eshushu yaza yasasazeka kulo lonke elase China.
Umenzi wentsimbi yaseJapan iNippon yentsimbi kunye neQela leSumitomo Corp elenza iimveliso zentsimbi ezomeleleyo ezizezi IiKhoyili eziQothuliweyo eziQhelekileyo kwimizi-mveliso yeemoto. Umenzi wensimbi waseMzantsi Korea u-POSCO, umzekelo, ugxininisa ekuveliseni iikhoyili ezishushu ezigobileyo ezifanelekileyo zokusetyenziswa kwizicelo zemoto kunye necandelo le-tubular kunye nokwakhiwa / iziseko.
Umthombo: Ihlabathi leNsimbi elivuthayo iFlame - Ngokutsho kwe-International Iron & Steel Institute, ishishini leemoto limele omnye wabasebenzisi abaphambili bekhoyili eqengqelekayo kunye nezona nxalenye zentsimbi zomelele kakhulu kwizithuthi zenziwe ziyisebenzisa. Ukunyuka kwemfuno yezithuthi ezikhaphukhaphu kunye ne-fuel-efficient iphelile ngokunyuka kokusetyenziswa kwee-coil rolled coil ezenza ukuba zingabikho ukuze zihlangabezane neemfuno ezifunekayo kwizicelo zemoto.
Ukusetyenziswa kweekhoyili ezishushu ezigoqiweyo kushishino lweemoto zineenzuzo ezininzi - zibonelela ngamandla okwandayo (nokuba kuthelekiswa nentsimbi ephezulu yamandla), ubunzima obulula bokusebenza kakuhle kwamafutha, kunye nokukhutshwa okuncinci. Ukongeza, ezi khoyili zivumela ukwenziwa kwamanani antsokothileyo ngeendleko eziphantsi ngokuchasene nezitampu eziqhelekileyo ezibonelela ngamathuba okudibanisa okunyukileyo kuyilo lwemoto.
Eyilwe ukuba ithathe umngeni wokunciphisa iindleko kwimveliso yeemoto ngelixa uqinisekisa umgangatho, iikhoyili ezishushu ezishushu zinika isisombululo esisebenzayo. Zikhethwa phakathi kwabavelisi ngenxa yokuba ziyisisombululo esingabizi kakhulu, ngokumalunga neendleko zokuvelisa xa kuthelekiswa nazo zonke ezinye iintlobo zeemveliso zetsimbi eziphezulu ezifana nentsimbi ebandayo.
Ukwenza iikhoyili ezishushu ezigoqiweyo kuqala ngokuphoswa kwezinto ezikrwada kwifomu ye-slab. Ezi slabs ziphinda zifudunyezwe kwiziko elimalunga ne-1,250 ° C ukuze zisebenze ngakumbi. Le coil yentsimbi ke idlula kumgca we-roller otyumzayo kwaye unwebe amacwecwe kuwo.
Intsimbi iya kuba neepropati ezintle zoomatshini kunye nokuqina, ubukhulu behlabathi jikelele be-flange. Emva koko, iikhoyili ziyapholiswa kwaye zicutshungulwe ngokwahlukileyo ngokwendawo eziza kusetyenziswa kuyo. Zinokunqunyulwa zibe ubude kwaye ziguqulwe zibe ngamashidi okanye zibunjwe ukuze zisetyenziswe kwishishini leemoto.
Kwizicelo, sinokhetho lokukhetha phakathi kweekhoyili ezishushu kunye nezibandayo. Iikhoyili ezishushu ezigoqiweyo zisetyenziswa kwizicelo ezifana neemoto, ulwakhiwo kunye namacandelo asisiseko apho kufuneka amandla aphezulu. Iikhoyili ezipholileyo, kwelinye icala zinomgangatho ophezulu wokugqiba zingasetyenziswa kwiintlobo zezicelo ezithembele kakhulu kwiziphumo ezichanekileyo ezifana nempahla yabathengi kunye ne-electronics.
Ngokuqhelekileyo, kwiiyunithi zokugcina ezibandayo, iikhoyili ezisongelwe ezishushu zineendleko eziphezulu kune-coil efanayo yemathiriyeli yokwenza intsimbi enexabiso eliphantsi xa isetyenziswa kwaye iya kusetyenziswa kwiminyaka emininzi kwiinkqubo ezinkulu zokwenziwa kwemveliso. Nangona kunjalo, ukuchaneka kunye nobuhle bekhoyili epholileyo buphakamisa oko unokukufumana ngeentsimbi ezishushu.
I-Hot rolled vs. i-coil-rolled coil Ekugqibeleni, babonelela ngokukhetha oko kuhambelana nenjongo yabo; isenokuba zizizathu ezinxulumene neendleko okanye kwiimfuno ezithile zokwenziwa kwemveliso. Kungakhathaliseki ukuba kukhethwe ntoni na, iikhoyili ezishushu ziya kuqhubeka zibalulekile ekwenziweni kweemveliso ezenziwe ngentsimbi kuluhlu lwamashishini - ezothutho kunye nolwakhiwo ngempahla yabathengi / ngombane.
Umgca wethu wemveliso uquka iintlobo ezininzi zeemveliso zetsimbi ezibandakanya i-carbon steel, insimbi engenasici, i-aluminium yangaphambili kunye ne-coil eshushu eshushu, phakathi kwabanye. Zisetyenziswa kakhulu kulwakhiwo, kwezothutho namandla, kunye nezixhobo zombane zamakhaya nakwezinye iindawo. Ukuhlangabezana neemfuno zabathengi bethu, sinikezela ngeenkonzo ezilungelelanisiweyo, ukwenza kunye nokuyila iimveliso zetsimbi ezihlangabezana neenkcukacha ezithile ngokweemfuno ezithile zabathengi.
Njengomvelisi weemveliso zetsimbi eziqengqelekayo ezishushu, sinamathela kwimodeli yeshishini ejolise emgangathweni kwaye ejolise kumthengi. Sisebenzisa iteknoloji yemveliso ephezulu kunye nezixhobo. Sikwajonga yonke inkalo yenkqubo yokuvelisa ukuqinisekisa ukuba sivelisa ezona mveliso zikumgangatho ophezulu. Ukongeza, sikwanalo neqela lolawulo lobulunga lobuchwephesha eliqhuba iitshekhi ezingqongqo zomgangatho kwibhetshi nganye yemveliso ukuqinisekisa ukuba iimveliso zanelisa ngokupheleleyo ulindelo kunye neemfuno zabo.
Siphuhlisa imakethi yamazwe ngamazwe kwaye sithumela iimveliso zethu eYurophu, eMelika naseAsiya ukongeza eAfrika nakweminye imimandla eyahlukeneyo. Ngeemveliso ezikumgangatho ophezulu kunye neenkonzo sizuze i-coil enkulu eshushu eqengqelekayo kunye nokuthembela kubathengi bethu. Siphuhlise ubuhlakani bobuchule bokudala iimarike ezintsha ngokubambisana neenkampani ezaziwayo.
I-Shandong Changheng Xinde i-coil eshushu ephothiweyo Ukulungiswa kugxile kwimveliso kunye nokuhanjiswa kweemveliso zentsimbi ye-premium efana neekhoyili kunye neepleyiti. Sibonelele abathengi ngeemveliso ezininzi zetsimbi ezahlukeneyo ezifana nentsimbi-engenasici, intsimbi yekhabhoni eyenziwe ngesinyithi kunye neepleyiti ezigqunywe ngombala, iiflange zangaphandle, ii-endplates zemfumba yesikwere, kunye nokunye. Ngobutyebi bamava oshishino kunye neqela lethu lobugcisa elinezakhono, siye saseka ngempumelelo ubudlelwane obuhlala ixesha elide kunye nabathengi abaninzi kwihlabathi liphela.
