I-Zn Coating Insimbi Encane Emnyama Evulekele I-engeli Engalingani Insimbi
Izinkomba zezingxenye: ukwakheka kwamakhemikhali ensimbi ye-engeli kuwuchungechunge olujwayelekile lwensimbi egoqayo, izinkomba eziyinhloko zokuqinisekisa yi-C, Mn, P, S ezine.Kuye ngebanga, okuqukethwe kuyahlukahluka, ngebanga elilinganiselwe lika-C<0.22%, Mn: 0.30-0.65%, P<0.060%, S<0.060%.
1. Izindlela zokuhlola.
1) Indlela yokuhlola ye-Tensile.Izindlela ezijwayelekile zokuhlola ezisetshenziswa yi-GB/T228-87, JISZ2201, JISZ2241, ASTMA370, ГОСТ1497, BS18, DIN50145, njll.
2) Indlela yokuhlola yokugoba.Izindlela ezijwayelekile zokuhlola ezisetshenziswa yi-GB/T232-88, JISZ2204, JISZ2248, ASTME290, ГОСТ14019, DIN50111, njll.
2. izinkomba zokusebenza: izinto zokuhlola zokuhlola ukusebenza kwensimbi ye-engeli ikakhulukazi ukuhlolwa okuqinile nokuhlolwa kokugoba.Izinkomba zihlanganisa iphuzu lokuvunwa, amandla aqinile, ubude kanye nokugoba izinto ezifanelekayo.
I-Angle steel isetshenziswa kabanzi ezakhiweni ezahlukahlukene zokwakha kanye nezakhiwo zobunjiniyela, njengemishayo yendlu, amabhuloho, imibhoshongo yokuhambisa amandla, imishini yokuphakamisa nezokuthutha, imikhumbi, iziko lezimboni, imibhoshongo yokusabela, ama-container racks namashalofu okugcina impahla, njll.
Ihlukaniswe kakhulu izigaba ezimbili: i-engeli ezinhlangothini ezilinganayo kanye ne-engeli enezinhlangothi ezingalingani, lapho i-engeli enezinhlangothi ezingalingani ingase iphinde ihlukaniswe ibe ukushuba okulinganayo okunezinhlangothi ezingalingani kanye nobukhulu obungalingani.
Ukucaciswa kwensimbi ye-engeli enobude obuseceleni kanye nokujiya kohlangothi losayizi wokumelwa.Njengamanje, imininingwane yensimbi ye-engeli yasekhaya ye-2-20, inani lamasentimitha enani lobude obuseceleni, inani elifanayo lama-engeli ngokuvamile linama-2-7 ahlukene ohlangothini.Ama-engeli angenisiwe amakwe ngosayizi wangempela wezinhlangothi zombili kanye nogqinsi oluseceleni futhi abonisa izindinganiso ezifanele.Ngokuvamile, ubude obuseceleni obungu-12.5cm noma ngaphezulu buyi-engeli enkulu, phakathi kuka-12.5cm-5cm yi-engeli ephakathi, kanti ubude obuhlangothini obungu-5cm noma ngaphansi buyi-engeli encane.

Ukuhleleka kokungenisa nokuthekelisa kwensimbi ye-engeli ngokuvamile kusekelwe ekucacisweni okudingekayo ekusetshenzisweni, futhi inombolo yayo yensimbi iyinombolo ehambisanayo yensimbi ene-carbon knotted.Futhi insimbi ye-engeli ayinakho ukwakheka okukhethekile nochungechunge lokusebenza ngaphezu kwenombolo yokucaciswa.Ubude bokulethwa kwensimbi ye-engeli buhlukaniswe ngezinhlobo ezimbili zobude obunqunyiwe nobude obuphindwe kabili.Uhlu lokukhethwa kobude obunqunyiwe bensimbi yasekhaya yi-3-9m, 4-12m, 4-19m kanye no-6-19m kuye ngenombolo yokucaciswa.Uhlu lokukhetha ubude lwensimbi ye-engeli eyenziwe e-Japan yi-6-15m.
Ukuphakama kwesigaba sama-engeli angalingani kubalwa ububanzi bohlangothi olude lwama-engeli angalingani.Ibhekisela ensimbi ene-angular cross section nobude obungalingani nhlangothi zombili.Ingenye yama-engeli.Ubude bayo obuseceleni busuka ku-25mm×16mm kuya ku-200mm×l25mm, obugoqwa umshini wokugaya oshisayo.
Ukucaciswa okujwayelekile kwama-engeli angalingani yilezi: ∟50*32--∟200*125 Ukuqina ngu-4-18mm.
I-GB/T2101-2008 (izinhlinzeko ezijwayelekile zokwamukelwa, ukupakishwa, ukumaka kanye nesitifiketi sekhwalithi yezigaba zensimbi)
I-GB/T706-2008 (ishintsha i-GB/T9787-88 GB/T9788-88) (usayizi, umumo, isisindo kanye nokuchezuka okuvumelekile kwama-engeli alinganayo / angalingani agingqika ashisayo).
I-JISG3192-94 (Amamo, ubukhulu, izisindo kanye nokuchezuka okuvumelekile kwezigaba ezigoqelwe ngokushisayo).
I-DIN 17100-80 (izindinganiso zekhwalithi zensimbi evamile yesakhiwo).
I-ГОСТ535-88 (izimo zobuchwepheshe zezingxenye zekhabhoni ezijwayelekile).
Ngokusho kwamazinga ashiwo ngenhla, ama-angles azolethwa ngama-bundle, ama-bundles azoboshwa, futhi ubude bezintambo buzohambisana nemithethonqubo.Ama-engeli ngokuvamile alethwa ngamaphakheji angenalutho futhi adinga ukuvikelwa kumswakama wokuthutha nokugcinwa.
