Mumakore achangopfuura, iyo isina musono simbi pombi indasitiri yenyika yedu yakawana kukurumidza kukurumidza munhoroondo, uye kugadzirwa uye kushambadzira kweanoenderera 6 makore, chigadzirwa chekugadzirisa mhedzisiro inoshamisa, uye chiyero chekuzvikwanira chepombi yesimbi inowedzera. gore negore.Muna 2004, kugadzirwa kwesimbi pombi kwakasvika 21.23 miriyoni matani, inodarika 25% yepasi rose simbi pombi kugadzirwa.Shanduko yetekinoroji uye kudyara kwasvika rekodhi yakakwira, uye michina yetekinoroji yakagadziridzwa zvakanyanya.Mamiriyoni maviri ematani matani ekugadzira pombi dzesimbi dzakabuda mabhizinesi abuda, achipinda mumapoka emapoka makuru epasirese epombi dzesimbi.
Sekuvandudzwa kweindasitiri yesimbi yeChina, kunyangwe indasitiri yepombi yesimbi yakaita zvinoshamisa mumakore achangopfuura, ichiverengera inodarika 1/4 yezvakabuda pasi rose, pachine imwe gwanza nedanho repamusoro repasirese maererano nemidziyo yehunyanzvi. , chigadzirwa chemhando uye giredhi, bhizinesi rehupfumi chiyero uye chikuru chehunyanzvi uye hupfumi zviratidzo.
Nekuongorora maitiro ekusimudzira uye maitiro emaindasitiri ane hukama muindasitiri yesimbi isina musono pombi, pamwe nekubudirira uye matambudziko eChinese seamless simbi pombi indasitiri, takaona kuti musika wepamba une imwe mukana uye nzvimbo yekusimudzira, uye nzvimbo yemusika wepasi rose. iri kuramba ichikura, uye nzira huru yekuvandudza chikamu chemusika ndeyemakwikwi.Kuti tiwedzere kukwikwidza, isu tinofanirwa kubata iripo mukana wakanaka wekudzikisa musiyano uripo pakati pezvakasiyana, mhando uye mutengo wezvigadzirwa uye yepamusoro-soro nhanho yepasirese nekukurumidza sezvinobvira, kuitira kuti tiwane yepamusoro-soro yepasi rose yezvigadzirwa zvekugadzira uye tekinoroji. , uye kuita kuti nyika yedu ive simba rine simba mukugadzirwa kwemachubhu esimbi munyika.
1. Kubudirira kwekugadzira uye kuoneka kwekushandisa mamiriro emuchina wesimbi pombi indasitiri muChina
Muna 2004, kubuda kweChina seamless simbi pombi uye welded simbi pombi ndiyo yokutanga munyika, uye musono simbi pombi yave mambure ekisipoti zvakasiyana siyana muna 2003. Kubva 2000, China simbi pombi indasitiri iri kukura nokukurumidza kwemakore mashanu akatevedzana. .Kukura kwekugadzirwa kwepombi yesimbi kunoda kuwiriraniswa nekukura kwezvigadzirwa zvesimbi zvakapedzwa munyika, ndiko kuti, avhareji yekukura kwezvigadzirwa zvesimbi zvakapedzwa ndeye 21.64%, uye kukura kwepombi yesimbi kuri 20.8%, uye chiyero chepombi / zvinhu. inochengetwa inenge 7%.
Kubva 1981 kusvika 2004, maitiro ese ekugadzira uye mashandisirwo ari pachena echubhu yesimbi isina musono yakawedzera zvishoma nezvishoma.Gore ra1999 risati rasvika, kushandiswa kwanga kwakakwira kudarika kugadzirwa kune imwe shanduko (inenge 800,000 t).Gore ra2002 risati rasvika, kushandiswa kwacho kwaive kwakakura zvishoma pane kugadzirwa kwemumba, uye muna 2003, yaive yakati sandara.Muna 2004, kugadzirwa kwakakura zvishoma pane kunwiwa kuri pachena, uye zvinotarisirwa kuti kugadzirwa kunotanga kudarika zvakanyanya kushandiswa kuri pachena muna 2005.
2. Kukwanisa kuvaka chimiro cheChina chisina musono simbi pombi indasitiri
Mazuva mashoma apfuura, nyika yedu ine musono vanogadzira pombi 130 kana zvakadaro, ingangoita mazana maviri seti yeyuniti.Pakati pavo, pane makambani anoda kusvika makumi matatu anogona kugadzira mapaipi anopisa akapedzwa ane midziyo yakakwana yetekinoroji, ine huwandu hwakakwana hwekugadzira hunopfuura mamirioni matanhatu t, inoverengera inopfuura 60% yehuwandu hwese mapaipi esimbi asina musono.Mhando iyi yekugadzira chirimwa ndiyo yakawanda kwazvo yemabhizinesi ehurumende, tekinoroji yepamusoro uye michina, yakakwirira-mutsara wekugadzira simba (Tianguan 250 unit, Baoshan Steel 140 unit pane anopfuura zviuru mazana masere ematani), mhando yechigadzirwa yakanaka, isina musono simbi. kugadzirwa kwepombi ndiyo inotungamira bhizinesi.Mamwe mabhizinesi akanyanya madiki uye epakati-saizi mabhizinesi anopa chubhu kana tsvina chubhu billet yekutonhora kutenderedza.Zvishandiso zvemabhizinesi akadaro zviri nyore.Iyo general process ndeye kushandisa perforation + musoro kana perforation + rolling pombi + musoro mushure mekushongedzera neinotonhora inotenderera inotonhora.
