Ko te rerekētanga i waenga i te hurihuri wera me te hurihuri matao ko te pāmahana o te tukanga hurihuri. Ko te tikanga o te "matao" ko te pāmahana noa, ko te tikanga o te "wera" ko te pāmahana teitei. Mai i te tirohanga a te mahi whakarewa, ko te rohe i waenga i te hurihuri matao me te hurihuri wera me wehewehe mā te pāmahana whakahou. Arā, ko te hurihuri i raro iho i te pāmahana whakahou he hurihuri matao, ā, ko te hurihuri i runga ake i te pāmahana whakahou he hurihuri wera. Ko te pāmahana whakahou o te maitai he 450-600 ℃.
Koinei te tirohanga whānui o ngā whakautu ki ngā pātai mō [Te Rerekētanga i waenga i te hurihuri wera me te hurihuri makariri]:
Ko te rerekētanga i waenga i te hurihuri makariri me te hurihuri wera ko te pāmahana o te tukanga hurihuri. Ko te tikanga o te "Matao" ko te pāmahana noa, ko te tikanga o te "wera" ko te pāmahana teitei. Mai i te tirohanga a te mahi whakarewa, ko te rohe i waenga i te hurihuri makariri me te hurihuri wera me wehewehe mā te pāmahana whakahou. Arā, ko te hurihuri i raro i te pāmahana whakahou he hurihuri makariri, ā, ko te hurihuri i runga ake i te pāmahana whakahou he hurihuri wera. Ko te pāmahana whakahou o te maitai he 450-600 ℃.
Ko te hurihuri wera me te hurihuri matao he tukanga hanga pereti rino, he kōtaha rānei, he pānga nui ki te hanganga me ngā āhuatanga o te rino. Ko te hurihuri o te rino he hurihuri wera te nuinga, ā, ko te hurihuri matao ka whakamahia anake hei hanga rino wāhanga iti me te pereti angiangi. He uaua ki te whakarerekē me te tukatuka i ngā poro, i ngā pire rānei i te pāmahana rūma. I te nuinga o te wā, ka whakamahanahia ki te 1100-1250 ℃ hei hurihuri. Ka kiia tēnei tukanga hurihuri he hurihuri wera. Ko te pāmahana mutunga o te hurihuri wera he 800-900 ℃ te nuinga, kātahi ka whakamataohia i te hau, nō reira ko te āhua hurihuri wera he rite ki te maimoatanga whakataurite. Ko te nuinga o te rino ka hurihia mā te hurihuri wera. Ko te hurihuri matao e pā ana ki te tikanga hurihuri o te whakaputa i te rino me te whakarerekē i te āhua o te rino me te pēhanga o ngā roera i te pāmahana rūma. Ahakoa ka whakamahanahia hoki te pereti rino e te tukanga tukatuka, ka kiia tonu he hurihuri matao.

Whakauruhia te whakamahinga whānui o te ngongo tapawhā hanga-matao
I roto i ngā whare ahumahi me ngā whare ā-iwi o Haina, kua maha ngā tau e whakamahia ana te raima whakapakari.
Huringa roa me te parahanga nui. I ngā tau tata nei, me te angitu o te hurihanga weraH-hikungā hua o Ma Steel me Lai Steel
E ai ki te whakaurunga o te mākete, kua whānui haere te whakamahinga o te hanganga maitai i roto i te umanga hanga. He maha ngā whare whakamātautau hanganga maitai, ngā whare tauira me ngā whare rongonui kua whakaurua mai tetahi i muri i tetahi. Kua tīmata hoki ngā paerewa me ngā whakaritenga mō te hoahoa me te hanganga ki te uru ki te wāhanga o te whakapai haere. Kua tino angitu te umanga hanganga maitai o Haina i ngā tau tata nei.
Heoi, i tēnei wā, ko ngā hanganga rino hanga whare o Haina e whakamahia ana mō te rino āhua-H hurihuri wera me ngā hanganga rino whakarewa rerekē. Kua eke te kaha o te rino āhua-H hurihuri wera i Haina ki te 3 miriona tana, ā, ko te putanga o te rino āhua-H māmā hurihuri me ngā hanganga rino rerekē he rau mano tana. Ko te putanga o ngā paipa whakarewa i Haina neke atu i te 7 miriona tana ia tau, ko te putanga ongā paipa tapawhā me ngā paipa tapawhā-hanga-mataoā, ko ngā hanganga rino matao-hanga maha mō te hanga hanganga rino he iti iho i te 5% o te putanga katoa o te rino matao-hanga. Kei te tīmatanga te whakamahinga o te rino matao-hanga i roto i ngā hanganga rino ahumahi me ngā hanganga ā-iwi i Haina. Kua tīmata noa te paipa whakarewa hanganga tapawhā me te tapawhā-hanga matao-hanga ki te whakakapi i te rino āhua-H hurihuri-wera hei pou hanganga rino. Kāore i te nui te whakamahinga o ētahi atu rino matao-hanga i roto i te umanga hanga.

I tēnei wā, kua hangaia e te Manatū Hanga ētahi whare whakamātautau hanganga maitai i roto i ngā whare ahumahi me ngā whare ā-iwi, pērā i
E rua ngā whare whakaaturanga hanganga rino a te Manatū Hanga i hangaia ki Tianjin i te tau 2002. I whakamahia ngā paipa rino i roto i tēnei kaupapa.
Pūnaha hanganga anga kurupae maitai maitai (SRC) pou raima, te whānuitanga o te kaupapa
8000m2, tekau mā tahi ngā papa o te tinana matua, he paipa porowhita te mea hanga o tētahi pou, ā, he paipa maitai tapawhā te mea hanga o tētahi atu pou.
350x350mm, ka rerekē te matotoru i runga i te papa, ko ngā papa 1~3 he 16mm, 4~
14mm mō te papa 6, 12mm mō te papa 7 ki te 9, 10mm mō te papa 10 ki te 11, ā, ringihia ana te paipa maitai ki roto.
Raima C40.
He mea hanga te kurupae ki te kurupae-I kua whakapirihia me te whakatakotoranga o te 350x200x10x18mm, ā, ko te pereti papa
He pereti hiato kua whakamātauhia i mua i te taumahatanga me te whakakaha rara porowhita kaha-teitei. I taua wā, kāore he kaihanga i Haina i hanga i ngā ngongo tapawhā me te diameter nui pēnei, nō reira i whakamahia ngā ngongo maitai tapawhā i roto i te kaupapa, arā, he pou BOX e whā kua whakapirihia ki te pereti.
Ko te kaupapa whare whakaaturanga hanganga rino a te Manatū Hanga o Tianjin Yuantai Derun Steel Pipe Manufacturing Group Co., Ltd. e ahu mai ana i ngā whakaaro e rua mai i te whakamahinga o te rino wāhanga matao (te nuinga he ngongo tapawhā) i roto i ngā whare hanganga rino:
Tuatahi, he nui te wāhi mākete mō ngā ngongo tapawhā hāngai matao nui, ā, he nui te maha o ngā papa e tika ana mō ngā whare noho hanganga maitai.
Me te 10~18 papa, he whakaritenga anō hoki mō aua hanganga waenga me te teitei mō ngā whakaritenga o ngā ngongo tapawhā hāngai-matao.
Tuarua, e toru ngā painga o ngā paipa maitai tapawhā ki ngā paipa maitai porowhita:
Tuatahi, he pai ake te kaha kawe me te mahi ru o ngā paipa tapawhā me te porowhita he rite te roa me te diameter o te taha.
Pai. E ai ki te whakamātautau i whakahaerehia e tētahi whare wānanga i Tianjin i runga i tētahi anga pou raima e toru ngā papa, e rua ngā whānui, he ngongo tapawhā, he ngongo porowhita hoki.
Ko te roa o te taha o te pou paipa he 150mm, ā, ko te whānui o te paipa porowhita he 150mm. E whakaatu ana ngā hua whakamātautau he ātete te mea tuatahi ki te pereti tuku kaha taha.
Ko te kaha kawenga me te kaha kawe mutunga he 80% teitei ake i te mea whakamutunga, ā, ko te taupū mahi rū whenua he tata ki te rua o te mea whakamutunga;
Tuarua, he pai ake te hanga paipa tapawhā. Me whakapai ake te pou raima o te whare noho hanganga maitai.
Mō te hanganga, ka hurihia te wāhanga porowhita ki te wāhanga tapawhā;
Tuatoru, he uaua ki te whakatau i te hononga i waenga i ngā pou raima porowhita me ngā kurupae. Hanganga maitai ā muri ake nei i Haina
I te mākete, ka whai wāhi nui ngā ngongo tapawhā me ngā ngongo tapawhā hanga-matao.
Ka taea e te whakamahana mata o ngā paipa maitai te whakapai ake i te rohe ngenge o te wāhanga mahi hua. Hei tauira, ko te hangarau tukatuka taketake o te haurua toki motuka i hangaia ki te maitai he whakamahana noa, ā, kua tata ki te 20 ngā wā kua roa ake tōna ora mahi mā te huri mai i te whakamahana mata ki te whakamahana. Hei tāpiri, ka whakaitihia e te whakamahana mata te aro o ngā wāhanga ki te korenga o te wāhi. Ko te kaupapa o te whakamahana mata he whakapai ake i ngā āhuatanga o ngā hua. He whānuitia te whakamahinga i roto i ngā momo mara, he hononga tata ki ngā āhuatanga o ngā mea e rua.
