Dhuumaha Alxan la'aanta ah ee Spiral
Tan iyo 1930-meeyadii, iyada oo horumarinta degdega ah ee tayada sare leh wax soo saarka duubista joogtada ah iyo horumarinta alxanka iyo tignoolajiyada kormeerka, tayada alxanka ayaa si joogto ah loo wanaajiyey, iyo noocyada kala duwan ee tuubooyinka birta welded ayaa sii kordhayay.Tollida tuubada birta ah.Tuubooyinka birta welded waxay u kala qaybsan yihiin tollayn toosan oo tubooyinka alxanka leh iyo tuubooyinka alxanka ee wareegsan iyadoo loo eegayo qaabka alxanka.Kala-soocidda habka wax-soo-saarka: habka kala-soocidda-tuubo alxanka leh, caabbinta tuubooyinka alxanka, (soo noqnoqda sare, soo noqnoqoshada hooseeya) tuubooyinka alxanka gaaska, tuubada welded foornada.
Tuubooyinka alxanka leh dhexroorka yar waxaa lagu alxamaa tol toosan, halka dhexroorka waaweyn ee tuubooyinka alxanka ah inta badan yihiin alxanka.Marka loo eego qaabka dhamaadka birta birta ah, waxay u qaybsan tahay tuubo welded wareegsan iyo qaab gaar ah (square, leydi, iwm.) tuubo welded;marka loo eego agabka iyo isticmaalka kala duwan, waxa loo kala qaybiyaa dareeraha macdanta Gaadhida tuubooyinka birta alxanka leh, tuubooyinka birta welded ee galvanized ee gudbinta dareeraha cadaadiska hooseeya, tuubooyinka birta alxanka leh ee korontada ku shaqeeya ee rullalusha suunka, iwm. Marka loo eego miiska cabbirka ee heerka qaran ee hadda jira , ku kala sooc dhexroorka dibadda * dhumucda derbiga yar ilaa weyn.
Qalabka sida caadiga ah loo isticmaalo tuubooyinka alxanka waa: Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 18Cr
Meelaha banaan ee loo isticmaalo tubooyinka birta alxanka ah waa biraha birta ah ama birta fidsan, kuwaas oo u kala qaybsan tuubooyinka foornada alxanka ah, tuubooyinka alxanka ee korontada ku shaqeeya iyo tuubooyinka alxanka ee tooska ah iyadoo ay ugu wacan tahay habka alxanka ee kala duwan.Sababtoo ah foomamka alxanka ee kala duwan, waxaa loo qaybin karaa laba nooc: tuubbo toosan oo alxan leh iyo tuubo alxan leh.Sababtoo ah qaabkeeda dhamaadka, waxay u qaybsan tahay tuubo welded wareega ah iyo qaab gaar ah (square, flat, etc.) tuubooyinka alxanka.Tuubooyinka alxanka leh ayaa loo qaybiyaa noocyada soo socda iyadoo ay ugu wacan tahay agabkooda iyo isticmaalkooda kala duwan:
GB/T3091-2008 (tubooyinka birta alxanka leh ee gaadiidka dareeraha cadaadiska hooseeya): Inta badan waxaa loo isticmaalaa in lagu qaado biyaha, gaaska, hawada, saliidda, biyaha kululaynta ama uumiga iyo guud ahaan dareeraha cadaadiska hoose iyo ujeedooyin kale.Waxyaabaha ay ka kooban tahay waa: Q235A birta darajada.
GB/T14291-2006 (Tuubka birta alxanka leh ee Gaadiidka Dheecaannada Macdanta): Inta badan waxaa loo isticmaalaa tolida toosan ee tubooyinka birta ee alxanka cadaadiska hawada miinada, dareeraha, iyo gaaska dheecaanka usheeda dhexe.Waxyaalaha uu matalo waa Q235A, birta darajada B.
GB/T12770-2002 (Tubabka birta welded ee birta ah ee qaab dhismeedka farsamada): Inta badan waxaa loo isticmaalaa mishiinada, baabuurta, baaskiilada, alaabta guriga, qurxinta hoteelada iyo makhaayadaha iyo qaybaha kale ee farsamada iyo qaybaha dhismaha.Qalabka ay ku matalo waa 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, iwm.
GB/T12771-1991 (Tubabka birta welded ee birta ah ee gaadiidka dareeraha): Inta badan waxaa loo isticmaalaa in lagu qaado warbaahinta daxalka hooseeyo.Agabka matale waa 0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2, iwm.
Intaa waxaa dheer, tuubooyinka birta alxanka ah ee qurxinta (GB/T 18705-2002), tuubooyinka birta alxanka leh ee qurxinta naqshadaha (JG/T 3030-1995), iyo tuubooyinka birta alxanka leh ee beddelayaasha kulaylka (YB4103-2000).
Dhuumaha dhaadheer ee alxanka leh ayaa leh habka wax soo saarka fudud, waxtarka wax soo saarka sare, kharash yar iyo horumar degdeg ah.Awoodda tuubooyinka alxanka leh ee wareegsan ayaa guud ahaan ka sarreeya kuwa tolmada toosan ee tuubooyinka alxanka leh.Meel bannaan oo cidhiidhi ah ayaa loo isticmaali karaa in lagu soo saaro tubooyinka alxanka leh ee leh dhexroorka tuubooyinka, iyo billeed leh ballac la mid ah ayaa sidoo kale loo isticmaali karaa in lagu soo saaro tubooyinka alxanka leh ee dhexroorka tuubooyinka kala duwan.Laakiin marka la barbar dhigo tuubada tolitaanka tooska ah ee isla dhererka, dhererka alxanka ayaa kordhay 30-100%, xawaaraha wax soo saarkuna wuu hooseeyaa.
Dhexroor weyn ama tuubooyinka alxanka weyn ayaa guud ahaan si toos ah looga sameeyaa meelaha bannaan ee birta ah, halka tuubooyinka yaryar ee alxanka leh iyo tuubooyinka alxanka ah ee dhuuban ay u baahan yihiin oo kaliya in si toos ah loogu lingaxo birta.Ka dib dhalaalid fudud ka dib, sawiriddu waa fiican tahay.
Kaabista: Tuubbada alxanka leh waxa lagu alxamaa bir xariijimo ah, sidaa awgeed uma sarrayso sida dhuumaha aan xidhnayn.
Habka dhuumaha alxanka
