China 27SiMn hydraulic simbi pombi mugadziri
27SiMn seamless simbi pombi, kureva 27 silicon manganese seamless simbi pombi, chimwe chezvinhu zvesimbi isina musono pombi, uye kabhoni iri pakati pe0.24-0.32%. SIMN yakanyorwa zvakasiyana nekuti zviri mukati mesilicon manganese muzvikamu zvishanu (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur s) inenge 1.10-1.40%. 27SiMn isina musono pombi yakanakira magetsi chirimwa, boiler chirimwa, indasitiri yemakemikari, mota uye zvikepe zvekushandisa, nezvimwe.
27SiMn, hydraulic strut pombi. Yakabatana kodhi yedhijitari: a10272
Standard: GB / t17396-2018
Iyi mhando yesimbi ine hupfumi huri nani pane 30Mn2 simbi, yakakwirira kuomarara, yakakosha kuomarara dhayamita ye8 ~ 22mm mumvura, yakanaka machinability, yepakati inotonhora deformation plasticity uye weldability; Pamusoro pezvo, kuoma kwesimbi hakudzike zvakanyanya panguva yekurapa kwekupisa, asi ine simba rakanyanya uye nekupfeka kusagadzikana, kunyanya kana mvura ichidzima; Nekudaro, simbi iyi inonzwira kune chena gwapa, hasha brittleness uye overheating senitivity panguva yekupisa kurapwa.
Rudzi urwu rwesimbi runonyanya kushandiswa mumamiriro ekudzima uye ane hasha kugadzira kupisa kutsika zvikamu zvinoda kuomarara kwepamusoro uye kusapfeka; Inogona zvakare kushandiswa pasi peyakajairwa kana inopisa yekutenderedza, senge tirakita track pini, nezvimwe.
Kushandiswa kwe27 SIMN isina musono pombi uye yakajairika simbi pombi

Mapaipi ese asina musono esimbi anozoyedzerwa ma mechanic properties. Nzira dzekuyedza dzemakanika zvivakwa dzinonyanya kukamurwa kuita mapoka maviri: tensile bvunzo uye kuomarara bvunzo.
Tensile bvunzo ndeyekugadzira isina musono simbi pombi kuita sampuli, dhonza sampuli kuti iputse pamushini wekutemesa wekuyedza, wobva wayera imwe kana akati wandei makina. Kazhinji, simba rekusimba chete, simba regoho, kureba mushure mekutsemuka uye kudzikiswa kwenzvimbo kunoyerwa.
Kuomarara bvunzo ndeyekudzvanya zvishoma nezvishoma indenter yakaoma mukati meiyo sampuli yepasi zvichienderana neyakatsanangurwa mamiriro, uyezve kuyedza kudzika kweiyo indentation kana saizi, kuti uone kuoma kwechinhu.
Yakanaka machinability, yepakati inotonhora deformation plasticity uye weldability; Pamusoro pezvo, kuoma kwesimbi hakudzike zvakanyanya panguva yekurapa kwekupisa, asi ine simba rakanyanya uye nekupfeka kusagadzikana, kunyanya kana mvura ichidzima; Nekudaro, simbi iyi inonzwira kune chena gwapa, hasha brittleness uye overheating senitivity panguva yekupisa kurapwa.
Chengetedzo yekutarisa kwekukwirira kwepamusoro kwepombi isina musono simbi
Chengetedzo yekutarisa kwekukwirira kwepamusoro kwepombi isina musono pombi inonyanya kusanganisira zvinotevera mapoinzi:
1. Kudzika uye chiyero chepamusoro decarburization.
2. Kureba uye kudzika kwekuremara kwepamusoro, shrinkage cavity, kuparadzaniswa kwepakati pekabhoni nesarufa.
3. Kugoverwa kweferrite uye pearlite mupombi yesimbi isina musono.
4. Zvimwe zviremara zvemicrostructure, pamwe nekukura kwezviyo, seamless pombi pamusoro pehukukutu uye kuiswa mukati.
