1. He korero poto mo te paipa hanga

Ko te paipa korekore mo te hanganga (GB / T8162-2008) e whakamahia ana mo te hanganga whanui me te hanganga miihini o te paipa korekore.Ka wehewehea te ngongo maitai ki roto i nga momo whakamahinga rereke.

Kowiri tira putorino tuitui mo te hanganga (GB/T14975-2002) ko te wera-hurihia (extruded, whakawhānui) me te matao-unu (hurihia) paipa tui hanga o te kowiri tira whakamahia i roto i te matū, hinu, pueru, hauora, kai, mihini me etahi atu ahumahi, paipa atete-waikura me nga waahanga hanganga me nga waahanga.

GB/T8162-2008 (putorino tui mo te hanganga) te nuinga whakamahia mo te hanganga whānui me te hanganga miihini.Ko ona taonga tohu (waitohu): waro maitai 20, 45 maitai, Q235, koranu maitai Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo , 42CrMo me etahi atu.

Pupa maitai tuitui

No te mea o tona tukanga hanga he rerekē, kua wehea te reira ki wera hurihia (extruded) ngongo maitai tui me te matao unu (hurihia) ngongo maitai tui e rua kinds.Cold-unu (hurihia) putorino kua wehea ki putorino porohita me motuhake-ahua putorino rua. momo.

A.Tirohanga o te rere tukanga

Te okeoke wera (te ngongo maitai karehia) : pire ngongo porowhita → whakawera → perforation → toru-roll cross okeoke, te huri haere tonu, te tangohanga ranei → te tihorea ngongo → te rahinga (whakaiti ranei) → te whakamahana → te ngongo tuwhera → te whakatikatika → te whakamatautau pehanga wai (he hapa ranei kitea) → tohu → rokiroki.

Ko te tuhi matao (te huri) ngongo maitai kore: pire ngongo porowhita → whakawera → perforation → pane → annealing → pickling → hinu (te whakakikorua parahi) → te tuhi matao-maha (te hurihuri makariri) → ngongo parakore → te whakamahana wera → te whakatikatika → te whakamatautau pehanga wai (kitenga hapa) → tohu → rokiroki.
