Njira yachitukuko ndi machitidwe amakampani aku China opanda chitoliro chachitsulo

M'zaka zaposachedwa, makampani osamata zitsulo chitoliro m'dziko lathu akumana ndi chitukuko chachangu m'mbiri, ndi kupanga ndi malonda kwa zaka 6 mosalekeza, zotsatira zosintha kapangidwe mankhwala ndi zodabwitsa, ndi kudzidalira mlingo wa chitoliro zitsulo ukuwonjezeka. chaka ndi chaka.Mu 2004, kupanga zitsulo chitoliro anafika matani 21.23 miliyoni, mlandu oposa 25% ya padziko lonse zitsulo chitoliro kupanga.Kusintha kwaukadaulo ndi ndalama zafika patali kwambiri, ndipo zida zaukadaulo zawongoleredwa kwambiri.Mabizinesi opanga matani mamiliyoni awiri opangira zitoliro opanda zitsulo atulukira, akulowa m'magulu akuluakulu padziko lonse lapansi.
Monga ndi chitukuko cha makampani zitsulo China, ngakhale makampani zitsulo chitoliro wapanga bwino kwambiri m'zaka zaposachedwapa, mlandu oposa 1/4 la linanena bungwe lonse, padakali kusiyana ena ndi mlingo mayiko patsogolo mwa mawu a zipangizo luso. , mankhwala khalidwe ndi kalasi, ogwira ntchito zachuma sikelo ndi zizindikiro zazikulu zaumisiri ndi zachuma.
Ndi kusanthula kachitidwe chitukuko ndi chitsanzo cha mafakitale okhudzana mu msika wosakanizika zitsulo chitoliro makampani, komanso zipambano ndi mavuto a makampani Chinese osataya zitsulo chitoliro, tinazindikira kuti msika zoweta ali ndi mwayi ndi chitukuko danga, ndi msika danga mayiko. ikukulirakulirakulirakulira, ndipo njira yayikulu yopititsira patsogolo magawo amsika ndi mpikisano.Kuti tipititse patsogolo kupikisana, tiyenera kugwiritsa ntchito mwayi womwe ulipo kuti tichepetse kusiyana pakati pa mitundu yosiyanasiyana, mtundu ndi mtengo wazinthu komanso kuchuluka kwapadziko lonse lapansi posachedwa, kuti tikwaniritse zida zapamwamba zapadziko lonse lapansi ndiukadaulo. , ndikupangitsa dziko lathu kukhala lamphamvu kwambiri popanga machubu achitsulo padziko lapansi.
1. Kukula kwapang'onopang'ono komanso kuoneka kwa kugwiritsidwa ntchito kwa mafakitale opanda chitoliro ku China
Mu 2004, linanena bungwe la Chinese seamless zitsulo chitoliro ndi welded zitsulo chitoliro ndi woyamba mu dziko, ndi chitoliro chosakanizika zitsulo wakhala ukonde katundu zosiyanasiyana mu 2003. Kuyambira 2000, China ndi zitsulo makampani chitoliro wakhala akutukuka mofulumira kwa zaka zisanu zotsatizana. .Kukula kwa kupanga zitsulo chitoliro ndi pafupifupi synchronized ndi kukula kwa zomalizidwa zitsulo mankhwala mu dziko, ndiko kuti, pafupifupi pachaka kukula anamaliza zitsulo zitsulo ndi 21,64%, ndi kukula zitsulo chitoliro ndi 20,8%, ndi chitoliro / zinthu chiŵerengero. imasungidwa pafupifupi 7%.
Kuchokera mu 1981 mpaka 2004, njira yonse yopangira ndi kugwiritsira ntchito chubu lachitsulo chosasunthika chinakula pang'onopang'ono komanso mofanana.Isanafike 1999, kumwa kunali kwakukulu kuposa kupanga ndi kusinthasintha kwina (pafupifupi 800,000 t).Chaka cha 2002 chisanafike, kumwa kumawoneka kuti kunali kokulirapo pang'ono kuposa kupanga kwapakhomo, ndipo mu 2003, kunali kosalala.Mu 2004, kupanga kunali kokulirapo pang'ono kuposa momwe amadyera, ndipo zikuyembekezeredwa kuti kupanga kudzayamba kupitilira kuchuluka komwe kukuwoneka mu 2005.
2. Ntchito yomanga mphamvu yamakampani aku China opanda chitoliro chachitsulo
Masiku angapo apitawo, dziko lathu liri ndi opanga mapaipi opanda msoko 130 kapena apo, pafupifupi ma seti 200 a unit.Pakati pawo, pali makampani pafupifupi 30 omwe amatha kupanga mapaipi omalizidwa otentha ndi zida zonse zaukadaulo, zokhala ndi voliyumu yopitilira 6 miliyoni, zomwe zimapitilira 60% ya kuchuluka kwa mapaipi opanda zitsulo.Chomera choterechi chimakhala ndi mabizinesi ambiri aboma, ukadaulo wapamwamba ndi zida, zida zapamwamba zopanga mzere umodzi (Tianguan 250 unit, Baoshan Steel 140 unit pa matani oposa 800), mtundu wazinthu ndi zabwino, zitsulo zopanda msoko. kupanga chitoliro ndi kutsogolera ogwira ntchito.Mabizinesi ena makamaka ndi mabizinesi ang'onoang'ono komanso apakatikati omwe amapereka chubu kapena zinyalala chubu billet pozizira kugudubuza.Zida zamabizinesi otere ndizosavuta.Zomwe zimachitika ndikugwiritsira ntchito perforation + mutu kapena perforation + kugudubuza chitoliro + mutu pambuyo pokonzekera kuzizira kozizira.
