Q355, P235GH, 210A1, T1, T11, T12 Round Bar Simbi

Round simbi inoshandiswa zvakanyanya mukuvaka, michina, aerospace, kugadzira mota uye mamwe minda.Mumunda wekuvaka, simbi yakatenderera inowanzoshandiswa kugadzira simbi yekuvaka, bhiriji, tunnel, nezvimwewo;mumunda wemakanika, simbi yakatenderedza inowanzoshandiswa kugadzira mabearings, magiya, couplings, nezvimwewo;mumunda wemuchadenga, simbi yakatenderedzwa inowanzoshandiswa kugadzira nzvimbo dzakasimba dzakasimba senge shaft injini yendege.

Carbon simbi inogona kupatsanurwa kuita yakaderera kabhoni simbi, yepakati kabhoni simbi zvinoenderana nemakemikari ayo (kureva, yepakati kabhoni simbi uye yakakwira kabhoni simbi).
(1), simbi yakaderera-kabhoni
Iyo inozivikanwawo sesimbi yakapfava, kabhoni yemukati kubva 0.10% kusvika 0.30% yakaderera kabhoni simbi iri nyore kubvuma zvakasiyana-siyana zvekugadzirisa senge forging, welding uye kucheka, inowanzoshandiswa mukugadzira maketani, rivets, mabhaudhi, shafts, nezvimwe.

(2), simbi yepakati kabhoni
Carbon steel ine 0.25% ~ 0.60% carbon content.Kune simbi yakadzikama, hafu yakadzikama simbi, simbi inopisa uye zvimwe zvigadzirwa.Pamusoro pekabhoni, inogona zvakare kuve nekashoma manganese (0.70% ~ 1.20%).Zvinoenderana nemhando yechigadzirwa, yakakamurwa kuita yakajairwa kabhoni chimiro simbi uye yepamusoro-mhando kabhoni chimiro simbi.Yakanaka kupisa kwemafuta uye kucheka kuita, kushomeka kwekuita welding.Simba uye kuoma kwakakwira kupfuura yakaderera kabhoni simbi, nepo plastiki uye kuoma kwakaderera pane yakaderera kabhoni simbi.Pasina kurapwa kwekupisa, shandisa zvakananga inopisa rolling zvinhu, inotonhora yekudhonza zvinhu, inogona zvakare kushandiswa mushure mekupisa kurapwa.Yakadzimurwa uye yakapfava yepakati kabhoni simbi ine yakanaka yakazara mechanicha zvivakwa.Hurema hwepamusoro hunogona kuwanikwa hunosvika HRC 55 (HB 538), uye σ b i600~1100MPa.Naizvozvo, mukushandiswa kwakasiyana-siyana kwepakati simba nhanho, kabhoni simbi yakave yakanyanya kushandiswa, mukuwedzera kune sezvivakwa zvekuvaka, asiwo nhamba huru inoshandiswa kugadzira akasiyana emakanika zvikamu.

(3) High carbon steel
Kazhinji inonzi simbi yemidziyo, iyo kabhoni yemukati inotangira pa0.60% kusvika 1.70%, inogona kuomeswa nekudzikamiswa.Sando nemarango zvinogadzirwa nesimbi ine 0.75% kabhoni yemukati;maturusi ekucheka akadai semadhiri, waya yekurovera uye reamers anogadzirwa kubva kusimbi ine 0.90% kusvika 1.00% kabhoni yemukati.
