Klasifikasi miturut Bentuk Cross-bagean
Telung jinis ing AS / NZS 1163 bisa dikategorikake miturut wangun bagean silang, yaiku:
Bagian Hollow Circular (CHS)
Bagian hollow persegi panjang (RHS)
Bagian Hollow Square (SHS)
Fokus artikel iki kanggo ngringkes syarat kanggo tabung baja karo bagean kothong bunder.
Klasifikasi Kelas Menengah AS/NZS 1163
Telung gelar ing AS / NZS 1163 adhedhasar kekuatan ngasilake minimal (MPA) saka produk rampung:
C250, C350 lan C450.
Cocog karo kelas tes impact suhu rendah 0 ℃ sing bisa ditemokake pipa baja:
C250L0, C350L0 lan C450L0.
Standar kasebut uga nyatakake yen cara sing bener kanggo nyebut kelas pipa baja yaiku:
AS/NZS 1163-C250 or AS/NZS 1163-C250L0
Bahan Baku
hot-rolled coil utawa Cold-rolled coil
Koil gulungan kadhemen yaiku gulungan gulungan panas sing wis ngalami pengurangan gulung kadhemen luwih saka 15%.Koil kasebut kudu duwe siklus anil subkritis sing nggawe rekristalisasi struktur lan mbentuk butir ferit anyar.Properti sing diasilake padha karo gulungan sing digulung panas.
Baja berbutir halus ditemtokake minangka bahan baku kanggo gulungan baja.Baja sing duwe ukuran butir austenitik nomer 6 utawa luwih alus nalika diuji miturut AS 1733.
Baja iki diprodhuksi dening metode Basic Oxygen Method (BOS) utawa Electric Arc Furnace (EAF) lan bisa dimurnikake kanthi Vacuum Arc Remelting (VAR), Electroslag Remelting (ESR), utawa kanthi proses nggawe baja sekunder kayata Vacuum Degassing utawa Injeksi Kalsium. .
Proses Manufaktur
Produk bagean kothong rampung bakal diprodhuksi dening proses kadhemen-mbentuk lan nggunakakelas tahan listrik (RW)Techniques kanggo nggabungake pinggiran Strip.
Jahitan las kudu longitudinal lan kudu ngilangi gangguan njaba.
Ora bakal ana perawatan panas sakabèhé ing prodhuk rampung.
AS/NZS 1163 Komposisi Kimia
AS/NZS 1163 ing tes komposisi kimia dipérang dadi rong kasus:
siji kasus yaiku bahan baku kanggo tes komposisi kimia,
liyane punika pengawasan pipe baja rampung.
Analisis Casting Baja
Analisis cast saka baja kudu digawe saka saben panas kanggo nemtokake proporsi saka unsur kasebut.
Ing kasus sing ora bisa ditindakake kanggo njupuk conto saka baja cair, analisis ing conto tes sing dijupuk miturut AS / NZS 1050.1 utawa ISO 14284 bisa dilaporake minangka analisis cast.
Analisis cast saka baja kudu tundhuk karo watesan kanggo kelas cocok diwenehi ingTabel 2.
Analisis Kimia saka Produk Rampung
