Ka whakamutua e te CEC o Zambia te tuku hiko ki Konkola Copper Mines
Ko te Copperbelt Energy Corp (CEC) o Zambia ka mutu te tuku hiko ki te waahanga a-rohe a Vedanta Konkola Copper Mines (KCM) mai i te Mane, i kii i muri i nga korero mo te toronga ki ta raatau kirimana tuku i pakaru i runga i nga nama nama ki a CEC.
I kii te Minita Pungao o Zambia a Mathew Nhkuwa ki a Reuters ka riro i a KCM tana mana tika mai i nga taputapu a te kawanatanga a Zesco, nana i hoko hiko ki a CEC mo te tuku atu ki a KCM.
I kii a Nkhuwa ko te kirimana tuku hiko nui i waenga i a Zesco me CEC, i pau i te Maehe 31, kaore e whakahoutia.
Ko te whakaaetanga tuku hiko i waenga i te CEC me te KCM i mutu ano i te Maehe 31, a, i whakaroahia na roto i te whakaaetanga kotahi tae noa ki te 31 o Mei, i kii a CEC i roto i tetahi korero i te Rātapu. He $132 miriona te nama a KCM ki te kamupene hiko, e kii ana a CEC.
"Kua pakaru nga whiriwhiringa mo tana toronga ake, ahakoa nga mahi pai a CEC i runga i te whakaaro pai ki te whai kirimana hou," ko ta te korero.
I kii tetahi korero korero a KCM, i muri i te paunga o tana kirimana me CEC, kua uru te kamupene ki tetahi atu kirimana me Zesco, i te Pipiri 1.
"Kei te tumanako matou he whakawhitinga korekore i roto i te tuku hiko mai i te CEC ki Zesco me te aukati, te aukati ranei ka waiho hei mahi sabotage," ko ta KCM.
I te ngana ki te whakaae ki te kirimana hou, i whai a CEC ki te whakatau i te $132 miriona taara nui a KCM me te whakapumautanga mai i a KCM mo te utu tika mo nga utu hiko a meake nei, e kii ana.
I kii a CEC kua whakamohio atu ki a KCM ka mutu tana tuku, me te kii ko tenei anake te whiringa i muri i nga korero kore.
"Kua tino tupato ki te whakarite ko te tukanga o te whakamutu i te tuku ka whakarite i te haumaru o nga kaimahi me nga taputapu me te pupuri i te pono o te maina," ko ta CEC.
Kei a Vedanta o Inia te 80% o KCM.
Ahakoa ka kawe a Zesco i te hiko ki KCM, ka haere tonu ma nga raina hiko CEC. I kii a Nkhuwa ka takahia e te CEC te ture mena kaore ia e whakaae ki te kawe i te mana.
"I tukuna e ahau he taputapu ture i te Paraire, e kii ana ko nga raina CEC he kaikawe noa. Na reira me kaha te CEC ki te kawe i te mana mai i Zesco ki te KCM he utu, "e kii ana a Nkhuwa.
Te Whiriwhiringa Rauemi Raina Pooro
He rereke nga mea pakaru, he rereke nga ahuatanga mahi me rereke nga raina rauemi kia pai. Ano hoki, ko te wahanga huri taratara me te wahanga huri miro pai e hiahia ana kia rereke nga raina rauemi.
H&G Machinery me te maha o nga kaihanga kuru o Haina. nga rauemi e whai ake nei hei whakarewa i to mira mira poroporo:
Konupora Steel
Ko te ihirangi konupora o te konupora teitei pereti mira mira mira te nuinga he 11-14%, me te ihirangi waro ko te tikanga 0.90-1.50%, te nuinga o nei kei runga ake 1.0%. I nga taumahatanga iti, ka eke te pakeke ki te HB300-400. I nga taumahatanga nui, ka eke te pakeke ki te HB500-800. I runga i te kawenga o te paanga, ka taea te hohonu o te paparanga whakapakeke ki te 10-20mm. Ka taea e te paparanga pakeke me te tino pakeke te aukati i te paanga me te whakaiti i te kakahu abrasive. Ko te rino konupora teitei he pai rawa atu te mahi aukati i te kakahu i raro i te ahua o te kaha o te awe o te awe, no reira ka whakamahia i roto i nga waahanga o te keri, nga mea hanga, te hiko waiariki, me etahi atu taputapu miihini. I raro i nga ahuatanga o te paanga iti, kaore e taea e te konupora teitei te whakamahi i nga ahuatanga o te rauemi na te mea kaore i te kitea te kaha o te whakapakeke mahi.

Chrome Alloy Steel
Ka wehea te rino koranu Chromium ki te rino chromium teitei (te ihirangi chromium 8-26% te ihirangi waro 2.0-3.6%), te rino whakarewa chromium reo (te ihirangi chromium 4-6%, te ihirangi waro 2.0-3.2%), te iti o te chromium E toru nga momo whakarewa rino (ko te chromium 1-3%, te waro 2.1-3.6%). Ko tana ahuatanga whakamiharo ko te microhardness o te M7C3 eutectic carbide ko HV1300-1800, ka tohatohahia i te ahua o te whatunga pakaru me te wehe i runga i te martensite (te hanganga tino uaua i roto i te matrix whakarewa) matrix, ka whakaiti i te painga o te pakaru i runga i te matrix. No reira, he kaha te kaha o te raima koranu-chromium teitei, he pakari te mira mira poroporo, he nui te aukati kakahu, a, ko ana mahi e tohu ana i te taumata teitei o nga taonga whakarewa o naianei.
