Chibvumirano chevashandi vemumigodhi vekuChina chakaonekwa chichimira pazvipingaidzo zvemitemo

Kuongororwa kuri kuramba kuchiitwa nemamineral-rich Australia neCanada kunogona kupfupisa kusawirirana kunotungamirwa nevacheri vemigodhi vekuChina uye kudzikamisa basa reBeijing mukubatanidza chikamu chegoridhe, vemabhanga nevanoongorora vakadaro.

Shandong Goridhe neZijin Mining zvakafambisa mafungu ekutora kubva kuCanada Arctic kuenda kuSouth America kuenda kuWest Africa gore rino.

Canada neAustralia munguva pfupi yapfuura dzakasimbisa zvirambidzo pakudyara nemafemu anotsigirwa nehurumende, vachityira kuparara kwehupfumi kunokonzerwa nedenda re coronavirus kuchaita kuti zvive nyore kutenga zvinhu zvine hungwaru. Hapana nyika dzakananga dzakadomwa pasi pemitemo yakadzokororwa.

Makambani eChinese mabhidhi emakambani eLithium eAustralia akatarisana nekudzoserwa kumashure apo mwedzi wapfuura Goldsea Group yekuChina yakasiya kutsvaga mugodhi wegoridhe Alta Metals mushure mekunge Australia's Foreign Investment Review Board (FIRB) yatsvaga imwe nguva yekuongorora chibvumirano.

Sarudzo yeFIRB "inoodza moyo zvakanyanya," Graeme Testar, director wePCF Capital Group muPerth, akaudza Reuters. "Iri igoridhe, harisi pazvicherwa zvakakosha."

Sangano iri rakati mwedzi wapera ichaongorora zvibvumirano zvese umo mutengi wekunze anotenga kufarira mu "sensitive national security bhizinesi" zvisinei nekukosha. Muna Kubvumbi yakavharira mari mbiri nevacheri veChinese muchikamu chezvicherwa chakakosha, senge lithium uye cobalt inoshandiswa munzvimbo dzepamusoro-soro senge simba rinodzokororwa, mabhatiri emotokari yemagetsi, uye dziviriro.

“Hurongwa hwemari yekunze hweAustralia hwakavhurika, huri pachena uye hunogamuchirwa. Tinogamuchira mari kubva kune chero nyika uye mune chero chikamu chehupfumi, "akadaro mutauriri weDhipatimendi rePfuma yeAustralia.

Zvipingamupinyi

Vamwe vemabhanga vari kutyira kuti FIRB inogona kuvharisa Tianqi Lithium yekuChina kutengesa chikamu chechikamu che51% muGreenbushes yekuAustralia, mugodhi mukuru welithium pasi rose, kune mutengi wekuChina.

"(Vatengi veChinese) vanoramba vachiratidza kufarira uye vanoda kutarisana nedambudziko rakawedzera reFIRB," akadaro Sherif Andrawes, mukuru weBDO wepasi rose we Natural Resources, achitaura nezvechikamu ichi.

"Mumwe maonero ndeokuti dambudziko rekuwedzera kune vatengi vekunze rakabatsira vanotora veAustralia," akadaro.

Canada yakataura njodzi dzakawedzerwa kune hupfumi uye kuchengetedzeka kwenyika uye yakati mari yese yekudyara nemafemu ehurumende ichasangana nekuongororwa kwakawedzerwa. Bazi reInnovation, Science and Economic Development Canada, iro rinoona nezvekudyarwa kwemari kubva kunze kwenyika, raramba kutaura zviri kunze kwegwaro rehurumende rataurwa pavakabatwa neReuters.

Vacheri vemigodhi vekuChina vari kutsvaga zvibvumirano nekuda kwezvirambidzo pakuongorora mudzimba, David Bo, aimbove maneja kuIvanhoe Mines, akadaro.

Zvingangosvika makumi matanhatu kubva muzana yeXilingol League yakapfuma mune zveChina mudunhu reInner Mongolia haibvumidzwe kuvacheri nekuda kwemaitiro ekuchengetedza zvakatipoteredza, zvichiwedzera kukurudzira kune vashandi vemumigodhi vekuChina kuita madhiri, mukuru wemigodhi wekuBeijing akaudza Reuters. Mukuru uyu aramba kudomwa nezita rake sezvo kambani yake yanga iri mushishi yekutsvaga mari yekunze kwenyika.

Shandong Goridhe yakamirira kubvumidzwa kuti itore Toronto-yakanyorwa TMAC Resources, inoshandisa mugodhi wegoridhe munharaunda yeCanadian Arctic yeNunavut. Vabati veTMAC vakatendera chibvumirano mwedzi wapera.

"Ichiri tariro yedu kuti Canada ... ichapa nzvimbo yakanaka, yakarurama uye isingasaruri kuti makambani ekuChina aise mari nekushanda muCanada," mumiriri weChina kuCanada Cong Peiwu akaudza Reuters mubvunzurudzo yaChikumi 11.

Asi nzvimbo yeArctic yemugodhi weTMAC's Hope Bay inogona kusimudza kushushikana, magweta nevanoongorora nezvekuchengetedza vakadaro.

Pane "mukana wakanyanya" Canada inovhara kutora, akadaro Jonathan Miller, mutevedzeri wemukuru uye mumwe mukuru kuOttawa-based Macdonald-Laurier Institute.

Makakatanwa akakonzerwa nekusungwa kweHuawei Technologies CFO, Meng Wanzhou, akawedzera mushure mekunge Beijing muna Chikumi yapomera vagari vaviri vakasungwa vekuCanada mhosva yevanofungidzirwa kuti vasori.

"Nemaonero iwayo ndinofunga zvichanetsa," akadaro Miller.

30CrNiMoRe Alloy Simbi Yekukanda Shredder Sando

Mutengi wedu weFinland akashandisa manganese simbi shredder sando kupwanya simbi inodzoreredza zvinhu. Nekudaro, iyo manganese sando inogona kungomhanya kutenderera maawa zana nemakumi mashanu. Nekuongorora nyundo yakashandiswa, kuoma kwenzvimbo yakashandiswa iHB186-222 chete. Zviyo zvishoma chete zvakawanikwa kuti zvitsvedze panzvimbo yekushandiswa, uye mazhinji acho aienderana nechimiro chematrix. Saka injinjini yedu inokurudzira 30CrNiMo alloy simbi inokanda idzo sando dzekuchenura.

30CrNiMo Chemical Kuumbwa

Nickel inovandudza kuoma uye kuoma kwesimbi yekugadzira. Kana nickel nechromium zvikashandiswa pamwechete, kuomarara kunenge kwakasimba, zvakanyanya kudarika kana zvinhu zviviri zvawedzerwa chete. Nekudaro, Cr Ni simbi inonzwa kune hasha brittleness, iyo inogona kukundwa nekuwedzera platinamu. Kuwedzera imwe chiyero chepasi isingawanzo mu alloy cast simbi inogona kunatsiridza chimiro chesimbi, kuchenesa muganho wezviyo, kunatsiridza iyo inclusions, kuitira kuti ivandudze kusimba kwekukanganisa uye kukanda zvimiro zvesimbi. Kuenzaniswa nedzimwe simbi, Cr Ni Pt re simbi imhando yemhando isingapfeki zvinhu zvine hurema hwakanyanya, kusimba kwepamusoro, uye kusimba kwepamusoro. Iyo chaiyo yemakemikari inoumbwa inoratidzwa muTafura 1.

Kugadzira Processing

Kunyungudutsa: iyo oxidation maitiro inoshandiswa mu5T EAF. Oxidation tembiricha ≥ 1550 decarburization huwandu ≥ 0.30%. Iyo decarburization mwero haisi pasi pe0.01% / min. Usati wabaya, 1.0kg/t aluminium inoiswa, uye alloy inowedzerwa pamwe nekuyerera kwesimbi. Kuumba: resin jecha repakati jecha, 8 zvidimbu pabhokisi. Kuita kwekuita kwesimbi iyi kwakafanana neyepakati kabhoni simbi. Kuti uvandudze density yekukanda yechikamu chinoshanda che shredder nyundo, riser inoiswa pamusoro.

Iyo yekupisa kurapwa maitiro ndeye 900-920 ℃ kudzima mvura, uye kupisa pa200 ℃.

Results

Mushure mekupedza chigadzirwa ichi, takatumira maviri seti kumutengi wedu. Zvichienderana nemhinduro yemutengi, iyi alloy simbi shredder sando span hupenyu hunogona kuita 2-2.5 nguva pane yakajairika manganese simbi sando.
