Ukuhlukaniswa kwensimbi ye-alloy
Okubizwa ngokuthiipayipi lensimbi ye-alloyukwengeza ezinye izakhi ze-alloy ngokusekelwe kunsimbi yekhabhoni, njenge-Si, Mn, W, V, Ti, Cr, Ni, Mo, njll., okungathuthukisa amandla, ukuqina, ukuqina, ukushibilika, njll. kokusebenza kwensimbi. Insimbi ye-alloy ingahlukaniswa ngokwezinto ze-alloy, futhi ekukhiqizweni nasekuphileni kwezimboni, insimbi ye-alloy izosetshenziswa ezimbonini ezithile, futhi kuvamile futhi ukuhlukanisa ngokwenhloso.
Ukuhlukaniswa ngokwezinto ezihlanganisiwe
Insimbi ye-alloy ephansi: inani eliphelele le-alloy lingaphansi kuka-5%;
Insimbi ye-alloy ephakathi nendawo: inani eliphelele le-alloy lingu-5 ~ 10%;
Insimbi ye-alloy ephezulu: inani eliphelele le-alloy lingaphezu kuka-10%.
Ukuhlukaniswa ngenhloso
Insimbi yokwakheka kwe-alloy: insimbi yokwakheka kwe-alloy ephansi (eyaziwa nangokuthi insimbi ejwayelekile ye-alloy ephansi); insimbi ye-alloy carburizing, insimbi ecinyiwe nethambile ye-alloy, insimbi yentwasahlobo ye-alloy; insimbi ephethe ibhola
Insimbi yamathuluzi e-alloy: insimbi yamathuluzi okusika i-alloy (kufaka phakathi insimbi yamathuluzi okusika i-alloy ephansi, insimbi yesivinini esikhulu); insimbi ye-alloy die (kufaka phakathi insimbi ye-die ebandayo, insimbi ye-die eshisayo); insimbi yamathuluzi okulinganisa
Insimbi yokusebenza ekhethekile: insimbi engagqwali, insimbi engagqwali, insimbi engagqwali, njll.
Inombolo yensimbi ye-alloy
Insimbi yesakhiwo enamandla aphezulu engxubevange ephansi
Igama lomkhiqizo walo lihlelwe ngokulandelana ngezingxenye ezintathu: uhlamvu lwe-pinyin lwesiShayina (Q) olumelela iphuzu lokukhiqiza, inani lomkhawulo wokukhiqiza, kanye nophawu lwebanga lekhwalithi (A, B, C, D, E). Isibonelo, i-Q390A isho insimbi yesakhiwo enamandla aphezulu ene-alloy ephansi enamandla okukhiqiza σs=390N/mm2 kanye nebanga lekhwalithi A.
Insimbi yesakhiwo se-alloy
Igama lomkhiqizo walo liqukethe izingxenye ezintathu: "izinombolo ezimbili, izimpawu zezakhi eziyishumi + izinombolo". Izinombolo ezimbili zokuqala zimele izikhathi eziyi-10,000 zengxenye yesisindo sekhabhoni esimaphakathi ensimbini, uphawu lwesakhi lubonisa izinto ezihlanganisayo eziqukethwe ensimbini, kanti izinombolo ezingemuva kophawu lwesakhi zibonisa izikhathi eziyi-100 zengxenye yesisindo esimaphakathi sesakhi. Lapho ingxenye yesisindo esimaphakathi yezinto ezihlanganisayo ingaphansi kuka-1.5%, ngokuvamile izakhi kuphela eziboniswayo kodwa hhayi inani lezinombolo; lapho ingxenye yesisindo esimaphakathi ingu-≥1.5%, ≥2.5%, ≥3.5%, ..., 2 no-3 ziphawulwa ngokufanele ngemuva kwezinto ezihlanganisayo, 4, . . . Isibonelo, i-40Cr inengxenye yesisindo sekhabhoni esimaphakathi i-Wc=0.4%, kanye nengxenye yesisindo se-chromium esimaphakathi i-WCr<1.5%. Uma kuyinsimbi yekhwalithi ephezulu, engeza u-"A" ekupheleni kwebanga. Isibonelo, insimbi engu-38CrMoAlA ingeyensimbi yesakhiwo ye-alloy esezingeni eliphezulu.
Insimbi ethwala ama-rolling
Faka u-"G" (uhlamvu lokuqala lwe-pinyin yesiShayina yegama elithi "roll") phambi kwegama lomkhiqizo, futhi inombolo engemuva kwayo ikhombisa izikhathi eziyinkulungwane zengxenye yobunzima be-chromium, futhi ingxenye yobunzima be-carbon ayimakiwe. Isibonelo, insimbi ye-GCr15 iyinsimbi ethwala ama-rolling enengxenye yobunzima obumaphakathi be-chromium WCr=1.5%. Uma insimbi ethwala i-chromium iqukethe izinto ezihlanganisayo ngaphandle kwe-chromium, indlela yokuveza lezi zinto ifana neyensimbi yesakhiwo se-alloy ejwayelekile. Izinsimbi ezithwala ama-rolling zonke ziyizinsimbi zekhwalithi ephezulu, kodwa u-"A" akenezelwa ngemva kwebanga.
Insimbi yamathuluzi e-alloy
Umehluko phakathi kwendlela yokubhala izinombolo yalolu hlobo lwensimbi kanye nensimbi yesakhiwo se-alloy ukuthi uma i-Wc <1%, inombolo eyodwa isetshenziswa ukukhombisa ingxenye yesisindo sekhabhoni ephindwe kayinkulungwane; lapho ingxenye yesisindo sekhabhoni ingu-≥1%, ayimakiwe. Isibonelo, insimbi ye-Cr12MoV inengxenye yesisindo sekhabhoni ephakathi kuka-Wc = 1.45% ~ 1.70%, ngakho ayimakiwe; ingxenye yesisindo esiphakathi kuka-Cr ingu-12%, kanti izingxenye zesisindo zika-Mo no-V zombili zingaphansi kuka-1.5%. Esinye isibonelo insimbi engu-9SiCr, i-Wc yayo ephakathi kuka-0.9%, kanti i-WCr evamile ingu-<1.5%. Kodwa-ke, insimbi yamathuluzi esivinini esiphezulu ihlukile, futhi ingxenye yayo yesisindo sekhabhoni ephakathi ayimakiwe kungakhathaliseki ukuthi ingakanani. Ngenxa yokuthi insimbi yamathuluzi e-alloy kanye nensimbi yamathuluzi esivinini esiphezulu kuyinsimbi yekhwalithi ephezulu, asikho isidingo sokumaka "A" ngemuva kwebanga layo.
Insimbi engagqwali kanye nensimbi engashisi
Inombolo ephambi kwalolu hlobo lwesigaba sensimbi ikhombisa izikhathi eziyinkulungwane zengxenye yesisindo sekhabhoni. Isibonelo, insimbi engu-3Crl3 isho ukuthi ingxenye yesisindo esimaphakathi i-Wc = 0.3%, kanye nengxenye yesisindo esimaphakathi i-WCr = 13%. Lapho ingxenye yesisindo sekhabhoni i-Wc ≤ 0.03% kanye ne-Wc ≤ 0.08%, iboniswa ngo-"00" kanye no-"0" phambi komkhiqizo, njengensimbi engu-00Cr17Ni14Mo2,0Cr19Ni9, njll.
