Ngingalinganisa Kanjani Ukuqina Kwendawo?
Ungakwazi ukubala ukungezwani kwendawo ngokulinganisa iziqongo zendawo ezimaphakathi nezigodi kuleyo ndawo. Isilinganiso sivame ukubonakala ngokuthi 'Ra,' okusho ukuthi 'Isilinganiso Sokuqina.' Nakuba i-Ra iyipharamitha yokulinganisa ewusizo kakhulu. Kuyasiza futhi ukunquma ukuthobela komkhiqizo noma ingxenye namazinga emboni ahlukahlukene.
Ukwenza lokhu kwenzeka ngokuqhathanisa namashadi angaphezulu.
Yini Ehlukanisa I-Ra ne-Rz Eshadini Lokugaqa Okungaphezulu?
U-Ra isilinganiso sobude obumaphakathi obuphakathi kweziqongo nezigodi. Iphinde ilinganise ukuchezuka emugqeni omaphakathi endaweni ngaphakathi kobude besampula.
Ngakolunye uhlangothi, i-Rz isiza ukukala ibanga eliqondile phakathi kwesiqongo esiphezulu nesiphansi kakhulu. Ikwenza lokhu phakathi kwamasampula obude obuhlanu bese ilinganisa amabanga akaliwe.
Yiziphi Izinto Ezithinta I-Surface Finish?
Kunezici eziningana ezithinta ukuphela kwendawo. Okukhulu kakhulu kulezi zici inqubo yokukhiqiza. Izinqubo zomshini ezifana nokujika, ukugaya, nokugaya kuzoncika ezintweni eziningi. Ngakho-ke, izici ezithinta ukuphela kwendawo zihlanganisa
okulandelayo:
Okuphakelayo kanye nesivinini
Isimo sethuluzi lomshini
Amapharamitha wendlela yamathuluzi
Sika ububanzi (i-stepover)
Ukuchezuka kwethuluzi
Sika ukujula
Ukudlidliza
Ukupholisa
Inqubo ye-Precision Tubes
Ubuchwepheshe bokucubungula nokwenza amapayipi anemba ensimbi engenasici asebenza kahle ahlukile kumapayipi endabuko angenamthungo. Izikhala zamapayipi endabuko angenamthungo ngokuvamile zikhiqizwa ukubhobozwa okushisayo okuyi-roll-rolling cross-rolling, futhi inqubo yokwenza amapayipi ngokuvamile ithatha inqubo yokwenza umdwebo. Amashubhu ensimbi engagqwali anemba ngokujwayelekile asetshenziswa kumathuluzi anembayo noma kumishini yezokwelapha. Akukhona nje kuphela ukuthi amanani aphakeme kakhulu, kodwa futhi ngokuvamile asetshenziswa kumishini eyinhloko namathuluzi. Ngakho-ke, izidingo zezinto ezibonakalayo, ukunemba kanye nokuqedwa kwangaphezulu kwamashubhu ensimbi engagqwali ngokunemba ziphezulu kakhulu.
Izikhala zeshubhu zezinto ezisebenza kanzima ukwenza izinto ezisebenza kanzima zivame ukukhiqizwa ngokukhipha okushisayo, futhi ukwakheka kwamashubhu ngokuvamile kucutshungulwa ngokugoqeka okubandayo. Lezi zinqubo zibonakala ngokunemba okuphezulu, ukuguquguquka okukhulu kwepulasitiki, kanye nezakhiwo ezinhle zesakhiwo samapayipi, ngakho-ke zisetshenziswa.
Imvamisa amapayipi ensimbi engagqwali anembile angu-301, insimbi engagqwali engu-304, insimbi engagqwali engu-316, insimbi engu-316L, insimbi engagqwali engu-310S. Ngokuvamile, kukhiqizwa izinto ezingaphezu kwe-NI8, okungukuthi, izinto ezingaphezulu kuka-304, futhi amashubhu anembile ensimbi engenasici anezinto eziphansi awakhiqizwa.
Kuwumkhuba ukubiza i-201 kanye ne-202 insimbi engagqwali, ngoba inozibuthe futhi iheha omazibuthe. I-301 nayo ayiyona i-magnetic, kodwa inguzibuthe ngemva kokusebenza okubandayo futhi iheha omazibuthe. Ama-304, 316 awawona amazibuthe, awakhangi kazibuthe, futhi awanamatheli kumazibuthe. Isizathu esiyinhloko sokuthi kukazibuthe noma cha ukuthi impahla yensimbi engagqwali iqukethe i-chromium, i-nickel nezinye izakhi ngezilinganiso ezahlukene kanye nezakhiwo ze-metallographic. Ukuhlanganisa lezi zici ezingenhla, futhi kuyindlela engenzeka yokusebenzisa odonsa ukuze bahlulele ikhwalithi yensimbi engagqwali, kodwa le ndlela ayiyona yesayensi, ngoba ekukhiqizeni insimbi engagqwali, kunomdwebo obandayo, umdwebo oshisayo, futhi kangcono ngemva- ukwelashwa, ngakho-ke i-magnetism incane noma ayikho. Uma kungalungile, i-magnetism izoba mkhulu, engakwazi ukukhombisa ubumsulwa bensimbi engagqwali. Abasebenzisi bangaphinda bahlulele ngokupakishwa nokubukeka kwamashubhu ensimbi engagqwali anembayo: ubuhwaqane, ukujiya okufanayo, nokuthi akhona yini amabala ngaphezulu.
Izinqubo ezilandelayo zokugingqa nokudweba zokucubungula amapayipi nazo zibaluleke kakhulu. Isibonelo, ukukhishwa kwamafutha kanye nama-oxide angaphezulu ku-extrusion akulungile, okuzophazamisa kakhulu ukunemba nekhwalithi yangaphezulu yamapayipi anemba ensimbi engagqwali.
