Insimbi, okuhlanganisa izingxenye zensimbi, ihlolwa ikhwalithi ngezindlela ezihlukahlukene, okuhlanganisa ukuhlola okuqinile, ukuhlola ukukhathala okugobayo, ukuhlola ukuminyanisa/ukugoba nokuhlola ukumelana nokugqwala.Izinto zokwakha kanye nemikhiqizo ehlobene ingathuthukiswa futhi ikhiqizwe ngesikhathi sangempela ukuze ulandelele ukusebenza kwekhwalithi yomkhiqizo, okungagwema ukubuyisela ngenxa yekhwalithi nokumoshakala kwezinto ezingavuthiwe.
Kunezinhlobo eziningana ezivamile zensimbi.
Insimbi Yekhabhoni
I-Carbon steel, eyaziwa nangokuthi i-carbon steel, iyingxube ye-iron-carbon ene-carbon content (wc) engaphansi kuka-2%.Ngaphezu kwe-carbon, i-carbon steel ngokuvamile iqukethe inani elincane le-silicon, i-manganese, isulfure ne-phosphorus.
Insimbi ye-Carbon ingahlukaniswa ngezigaba ezintathu: insimbi ye-carbon structural, insimbi yensimbi ye-carbon kanye nensimbi yesakhiwo esisika mahhala.I-Carbon structural steel ingabuye ihlukaniswe ngezinhlobo ezimbili zensimbi yesakhiwo yokwakha kanye nokwakhiwa komshini.
Ngokusho kokuqukethwe kwekhabhoni kungahlukaniswa ngensimbi ephansi ye-carbon (wc ≤ 0.25%), i-carbon steel (wc 0.25% ~ 0.6%) kanye ne-high carbon steel (wc> 0.6%).Ngokusho kwe-phosphorus, okuqukethwe kwesibabule kungahlukaniswa ngensimbi evamile ye-carbon (equkethe i-phosphorus, isulfure ephakeme), i-carbon steel yekhwalithi ephezulu (equkethe i-phosphorus, isulfure ephansi) nensimbi yezinga eliphezulu (equkethe i-phosphorus, isulfure ephansi).
Ukuphakama kwekhabhoni ku-carbon steel ejwayelekile, kuyanda ubulukhuni namandla, kodwa ipulasitiki iyancishiswa.
Izinsimbi zesakhiwo sekhabhoni
Lolu hlobo lwensimbi ikakhulukazi ukuze kuqinisekiswe izakhiwo zemishini, ngakho-ke ibanga lalo libonisa izakhiwo zalo zemishini, ngezinombolo ze-Q +, lapho u-“Q” wephuzu lokukhiqiza elithi “Qu” uhlamvu lwe-Hanyu Pinyin yokuqala, inombolo ikhombisa inani lephoyinti lesivuno, isibonelo, i-Q275 ithe iphuzu lesivuno lika-275MPa.Uma ibanga limakwe ngezinhlamvu A, B, C, D, kusho ukuthi izinga lezinga lensimbi lihlukile, liqukethe inani le-S, P ukuze kuncishiswe inani lekhwalithi yensimbi ukuze kuthuthukiswe.Uma uhlamvu "F" luphawulwe ngemuva kwebanga, luyinsimbi ebilayo, ephawulwe ngokuthi "b" ngensimbi ehlala kancane, engaphawulwanga ukuthi "F" noma "b" ngensimbi ehlala phansi.Isibonelo, i-Q235-AF isho insimbi ebilayo yezinga elingu-A enephuzu lokukhiqiza elingu-235 MPa, futhi i-Q235-c isho insimbi ethule esezingeni elingu-c enephuzu lokukhiqiza elingu-235 MPa.
Izinsimbi zesakhiwo sekhabhoni zivame ukusetshenziswa ngaphandle kokwelashwa kokushisa kanye nesimo esihlinzekiwe ngokuqondile.Ngokuvamile izinsimbi ze-Q195, i-Q215 ne-Q235 zinengxenye ephansi ye-carbon mass, izakhiwo ezinhle zokushisela, ipulasitiki enhle nokuqina, zinamandla athile, futhi zivame ukugoqwa zibe amapuleti amancane, imigoqo, amapayipi ensimbi ashiselwe, njll., asetshenziswa kumabhuloho, izakhiwo kanye nezinye izakhiwo kanye nasekwakheni ama-rivets avamile, izikulufu, amantongomane nezinye izingxenye.Izinsimbi ze-Q255 ne-Q275 zinengxenye ye-carbon ephakeme kakhulu, amandla aphakeme, ipulasitiki engcono kanye nokuqina, zingashiselwa, futhi ngokuvamile zigoqeka Zivamise ukugoqwa zibe izingxenye, imigoqo namapuleti ezingxenye zesakhiwo kanye nokwenza izingxenye ezilula zemishini. njengezinduku zokuxhuma, amagiya, ama-coupling namaphini.
