Te rerekētanga i waenganui i te kiriata parera paraihe me te kiriata parera makariri

(1) ko te papa taraiwa makariri e kaha ai te whakakaha i te kaha o te whakapōkai, he iti noa te kaha o te whakapōkai, engari ka taea te whiwhi i te tau o te kaha o te whakapōkai pai ake, ka whakamahia mō te papa taraiwa makariri, te papa taraiwa, me ētahi atu wāhanga.

(2) ko te papa makariri ka whakamahi i te mata taraiwa makariri kāore he kiri tōtō, he kounga te kounga. Ko te papa taraiwa hau paripari ka whakamahi i te mata o te tāhuna hau paripari, ko te rahi o te papa he rerekētanga.

(3) ko te kaha o te papa taraiwa hau paripari me te rite o te mata he iti noa, he iti noa te utu, i te wā e taraiwa ana ko te papa taraiwa he pai ake te kaha, te kaha, engari he utu nui ake.

(4) ko te taraiwa e wehe ana i te papa taraiwa makariri me te papa taraiwa hau paripari, ko te tere whakaputanga anō te pūtake o te wehenga.

(5) Ko te rere taraweti: ko te rere taraweti e whakamahia ana i te whanaketanga o te kapi, kei te tere ake tana rere. Ko te papa taraweti: ko te rere taraweti he rite ki te rere taraweti.

(6) Ko te mata o te papa taraweti kaore he tata, ka rereke te mata, ko te mata o te papa rere taraweti kaore he tata, ko te mata he kākāriki, a muri i te tata, ka taea te whakawātea mai i te rereke o te mata, he aha tēnā i te papa taraweti.

papa rere tarawetiTe whakamārama i te papa taraweti

Ko te whānui o te papa taraweti he iti ake rānei i te 600mm, ko te tuku o te papa taraweti he 0.35-200mm, ko te tuku o te papa taraweti he 1.2-25mm.

Hot Rolled Strip Market Positioning and Development Direction

Ko te miro hiko taraiwa he tahi o ngā tikanga matua o ngā hua taraiwa, kua whakamahia whānuitia ki te ahumahi, ki te tuarāwhiti, ki te waka, ki te hanga hoki, i te wā anō hoki hei rāwaro mō te rīpene taraiwa makariri, te pīpī taraiwa hui, te taraiwa hāngai makariri me ētahi atu rawa hua, kei te nui ake te nui o te hua i te tau ki te hua taraiwa o Haina.

Ki ngā whenua e whanake ana te ahumahi, ko te papa taraiwa makariri me te miro taraiwa e noho ana i te 80% o te hua o te papa me te miro taraiwa, e noho ana i te 50% atu rānei o te hua taraiwa katoa, kei te tūārangi hoki ki te whakataetae o te ao.

Ki Haina, ko te miro taraiwa hiko tikanga, ko te 1.8mm te iti rawa o te tino, engari i te kātata anō, he iti noa ngā kaihanga e hua ana i te miro taraiwa hiko e iti ake i te 2.0mm te tino, me te miro taraiwa anō hoki, ko te tino o te hua he nui ake i te 2.5mm.

Nō reira, he nui te wāhi e tūwhera ai te iti ake i te 2mm te rawa kaiwhakamahi, me whakamahi i te parirau parirau.

Ripanga Whakawhiti Māmā

Parirau parirau paraima: ko te rere o te rino i raro i te āhuarangi rere ki te rere i te rere, e mōhiotia hoki ko te parirau parirau, e mōhiotia ana ko te parirau kaore i te whakaputua i te wera me te rere noa i te wā kauwhau. Ko te parirau parirau pea he wera ki te whakapā, engari kei te karanga tonu i te parirau parirau.

Ko te whanaketanga parirau parirau e āwhina i te tini o ngā papa rino me ngā parirau tikangia te tikanga, ko tāna hoki āhuatanga matua ko te iti noa te wera, ina whakaritea ki te whanaketanga wera, he āhua āhua āwhina ake ēnei:

(1) Ko ngā hua parirau parirau he tika te rahi me te ōrite te rahi, ā, ko te rerekētanga o te rahi o te parirau he iti noa i te 0.01-0.03mm, e ōrite ana ki te here o te tika o te tika.

(2) Ka taea ngā āhua anō te iti kāore i te taea e te hiko hotoke te whakaputa (ko te iti rawa ka taea te 0.001mm, te iti ake rānei).

(3) Kei te nui ake te kounga mata o ngā hua hiko makariri, kāore he kiriata pāpaku e kitea ana i te hiko hotoke, te hurihia ki roto i te parurenga rino rānei, ā ka taea te whakaputa i ngā āhua rereke o te mata kia rite ki ngā hiahia o te kaiwhakamahi (āhua kiriata, āhua pāpaku rānei), kia māmā ai i te mātātoko i te mahinga e whai muri ana.

(4) He āhua pai ngā āhuatanga me ngā āhuatanga tikanga o te hiko hiko makariri (pērā i te kaha ake, te poto ake te āpiti, te āhua pai te mahi tōpiko rānei).

(5) Ka taea te hiko i te tere tino pikinga, me te hiko tōtika tōtika hoki, me te nui ake te hahau.

Whakawhitinga hiko makariri

Ko te hiko hiko makariri e rua ngā āhua: pango, me te kiriata.

(1) pīpī parakare kākāriki: pīpī parakare maru whakaputua ki te pāmahana parakare, te tae mata i runga i te raru o te pāmahana teitei ki te hau kākāriki. Ko ngā āhuatanga tinana ka pāpaku, ka whakamahia katoa mō te pīpī parakare, kātā i muri i te whakapōki, te tohua, te whakapōpō i te nuinga o te mahi hohonu.

(2) pīpī parakare mārama: me te rerekētanga nui ake o te parakare kākāriki ko te mea ko te whakaputa kāore i te hau e whakawhāwhā ana, engari kua tiakihia ki te nītrogeni me ētahi atu kāiri hākona, te tae mata kia noho penei i te pīpī parakare maru, i runga i te kākāriki parakare ka whakamahia anō hoki mō te uhi uhi, me ētahi atu tini mōhio mata, mārama me te rite.

He aha te rerekētanga i waenganui i te pīpī parakare mārama me te pīpī parakare kākāriki: ko ngā āhuatanga hinahina he tāpiri, ko te pīpī parakare mārama he pīpī parakare kākāriki i runga i te parakare kākāriki anō hoki tētahi tahua mārama.

Whakamahinga: ko te mātāpuna parakiru he nuinga o te waihanga i ngā hua mutunga i mua i te pai ki te whai i ētahi mahi whakapai ake i te whenua, ka taea e te mātāpuna māriki te whakapumau tika ki ngā hua mutunga.

Tirohanga whānui o te whanaketanga o te huihuinga mātāpuna makariri

Ko te hanga hangarau mātāpuna makariri he tohu nui o te taumata whanaketanga o te umanga mātāpuna. Ko te para mātāpuna māmā mō te motukā, te waka tari, te umanga huinga, te kaihanga kai, te hanga, ngā taputapu hiko rānei, engari he hononga anō hoki ki te oranga ia rā, pērā i te huringa whare, te mākawe horoi, ngā tākunetia rānei e hiahiatia ai te para mātāpuna māmā. Nō reira, i ētahi whenua umanga whanaketia ana, ko te wāhi e noho ana te para mātāpuna māmā i te ōweenga o te mātāpuna ka piki ake ia tau, i roto i te para mātāpuna, mātāpuna māmā, ngā hua makariri e noho nui ana.
