Gariiradda birta duuban ee kulul
Cabbirka saxanka birta ah waa inuu buuxiyaa shuruudaha miiska "Xajmiga iyo Tilmaamaha Taarikada Birta ah ee kulul (laga soo xigtay GB / T709-1988)".
Baaxadda xariijinta birta waa inay buuxisaa shuruudaha miiska "Cabbirka iyo Tilmaamaha Xarigga Birta ee Hot Rolled Strip (laga soo xigtay GB / T709-1988)".
Ballaca saxanka birta wuxuu kaloo noqon karaa cabbir kasta oo ah 50mm ama dhowr 10mm ah.
Dhererka saxanka birta ah waa cabbir kasta oo ah 100mm ama dhowr 50mm, laakiin dhererka ugu yar ee saxanka birta ee ballaciisu ka yar yahay ama la mid yahay 4mm waa inuusan ka yarayn 1.2m, iyo dhererka ugu yar ee saxan bir ah. dhumucdiisuna tahay 4mm waa inuusan ka yarayn 2m.
Marka loo eego shuruudaha, dhumucda saxan bir ah oo ka yar 30mm, dhexda dhumucda waxay noqon kartaa 0.5mm.
Marka loo eego baahida, ka dib gorgortan dhex mara alaab-qeybiyaha iyo iibsadaha, taarikada birta ah iyo xajmiyada cabbirro kale ayaa la keeni karaa.
Dhumucda guud:0.8, 1.0, 1.2, 1.5, 1.8, 2.0, 2.35, 2.45, 2.50, 2.70, 2.75, 2.8, 2.9, 2.95, 3.0, 3.25, 3.3, 3.5, 3, 9, 9 4.25 , 4.5, 4.7, 4.75, 5, 5.5, 5.75, 6, 6.75, 7, 7.5, 7.75, 8, 8.75, 9, 9.5, 9.75, 10, 10.5, 11, 11.5, 12
Wareegga joogtada ah ee kulul waxaa loo qaybin karaa birta qaab dhismeedka kaarboon ee caadiga ah, birta daawaha hoose, iyo birta daawaha iyadoo loo eegayo alaabteeda iyo waxqabadkeeda.Marka loo eego adeegsigooda kala duwan, waxaa loo qaybin karaa: birta samaynaysa qabow, birta qaab dhismeedka, birta qaab dhismeedka baabuurta, birta qaab dhismeedka daxalka u adkaysta, birta qaab dhismeedka farsamada, silsilad gaas alxan leh iyo birta weelka cadaadiska, birta dhuumaha, iwm.
Cutubka saxan-kulul-kulul ee galvanized galvanized kulul wuxuu qaataa habka Sendzimir annealing oo la wanaajiyey, iyo alaabta ceeriin waa gariiradaha la dubay oo kulul.Habka wax-soo-saarku waa sida soo socota:
Gariiradda kulul ee duuban → furfurida → jarista madaxa iyo dabada → alxanka → looper albaabka → wax laga beddelay Sendzimir foornada jiifka toosan → galvanizing kulul → qaboojin ka dib → cabirka dhumucda lakabka zinc → toosinta iyo toosinta → Duubista → Culayska iyo baakaynta → Kaydinta alaabta oo dhammaatay.
