Icyuma cya S460N / Z35 gisanzwe, icyapa cy’iburayi gisanzwe gifite ingufu, S460N, S460NL, S460N-Z35 umwirondoro wibyuma: S460N, S460NL, S460N-Z35 ni ubushyuhe buzengurutswe bwo gusudira ibyuma byimbuto nziza muburyo busanzwe / busanzwe bwo kuzunguruka, icyiciro cya S460 bitarenze 200mm.
S275 kubijyanye no gushyira mu bikorwa ibyuma bitavanze byubaka: EN10025-3, nimero: 1.8901 Izina ryicyuma rigizwe nibice bikurikira: Inyuguti yikimenyetso S: ibyuma byubatswe bijyanye nuburebure bwa munsi ya 16mm agaciro kimbaraga: agaciro k'umusaruro muke Gutanga: N isobanura ko ingaruka ku bushyuhe butari munsi ya dogere -50 zigaragazwa ninyuguti nkuru L.
S460N, S460NL, S460N-Z35 Ibipimo, imiterere, uburemere no gutandukana byemewe.
Ingano, imiterere no gutandukana byemewe byicyuma bigomba kubahiriza ibivugwa muri EN10025-1 muri 2004.
S460N, S460NL, S460N-Z35 imiterere yo gutanga Ibyapa mubisanzwe bitangwa muburyo busanzwe cyangwa binyuze mukuzunguruka bisanzwe mubihe bimwe.
S460N, S460NL, S460N-Z35 Ibigize imiti ya S460N, S460NL, S460N-Z35 ibyuma bigize imiti (gusesengura gushonga) bigomba kubahiriza imbonerahamwe ikurikira (%).
S460N, S460NL, S460N-Z35 ibisabwa bigize imiti: Nb + Ti + V≤0.26;Cr + Mo≤0.38 S460N Gushonga Isesengura rya Carbone Ihwanye (CEV).
S460N, S460NL, S460N-Z35 Ibikoresho bya mashini Ibikoresho bya mashini hamwe nibikorwa bya S460N, S460NL, S460N-Z35 bigomba kuba byujuje ibisabwa mumeza akurikira: Imiterere ya S460N (ibereye guhinduranya).
S460N, S460NL, S460N-Z35 imbaraga zingaruka muburyo busanzwe.
Nyuma yo guhuza no gukora ibisanzwe, ibyuma bya karubone birashobora kubona imiterere iringaniye cyangwa yegeranye, kandi nyuma yo kuzimya, irashobora kubona imiterere idahwanye.Kubwibyo, mugihe wiga imiterere nyuma yo kuvura ubushyuhe, ntabwo igishushanyo cya feri ya karubone yicyuma gusa ahubwo nicyerekezo cyo guhinduranya isothermal (C curve) yicyuma kigomba koherezwa.
Igishushanyo cyicyuma cya karubone kirashobora kwerekana uburyo bwo gutondekanya ibintu bivanze no gukonjesha buhoro, imiterere yubushyuhe bwicyumba nubunini ugereranije nibyiciro, hamwe na C umurongo urashobora kwerekana imiterere yicyuma hamwe nibintu runaka mubihe bitandukanye byo gukonja.C umurongo ubereye ibihe byo gukonjesha;CCT umurongo (austenitike ikomeza gukonjesha umurongo) irakoreshwa mubihe bikonje bikonje.Ku rugero runaka, C umurongo urashobora kandi gukoreshwa mukugereranya impinduka za microstructure mugihe gikonje gikomeje.
Iyo austenite ikonje buhoro (bihwanye no gukonjesha itanura, nkuko bigaragara ku gishushanyo cya 2 V1), ibicuruzwa bihinduka byegereye imiterere iringaniye, aribyo pearlite na ferrite.Hamwe n'ubwiyongere bw'igipimo cyo gukonja, ni ukuvuga, iyo V3> V2> V1, gukonjesha kwa austenite bigenda byiyongera buhoro buhoro, kandi umubare wa ferrite yaguye ugenda ugabanuka, mu gihe ingano ya pearlite yiyongera buhoro buhoro, kandi imiterere ikaba nziza.Muri iki gihe, ferrite yimvura yagabanijwe ahanini ikwirakwizwa kumupaka wingano.
Kubwibyo, imiterere ya v1 ni ferrite + pearlite;Imiterere ya v2 ni ferrite + sorbite;Microstructure ya v3 ni ferrite + troostite.
Iyo igipimo cyo gukonjesha ari v4, umubare muto wa neti ferrite na troostite (rimwe na rimwe hashobora kuboneka umubare muto wa bainite) urashobora kugwa, kandi austenite ihinduka cyane muri martensite na troostite;Iyo igipimo cyo gukonja v5 kirenze igipimo gikomeye cyo gukonjesha, ibyuma bihinduka rwose muri martensite.
Guhindura ibyuma bya hypereutectoid bisa nibyuma bya hypoeutectoid, hamwe nibitandukaniro ferrite igwa mbere mubyanyuma naho simaite igwa mbere mubyambere.
