42CRMO Seamless Simbi Pipe
Chinangwa che42crmo seamless simbi pombi: Iyo yakakosha simbi giredhi yemabhiriji "42crmo", yakakosha simbi giredhi yemagidhi emotokari "42CRmo", uye yakakosha simbi giredhi yezvitsiga zvekumanikidza "42Crmo".Iyi mhando yesimbi inotsamira pakugadzirisa kabhoni (C) zvirimo kuti ivandudze ma mechanika esimbi.Nokudaro, maererano nehuwandu hwehuwandu hwekabhoni, rudzi urwu rwesimbi runogona kupatsanurwa kuva: Low carbon steel-iyo kabhoni yemukati kazhinji isingasviki 0.25%, yakadai se10, 20 simbi, nezvimwewo;yepakati kabhoni simbi-kabhoni yemukati kazhinji iri pakati pe0.25 ne0.60%, senge 35, 45 simbi, zvichingodaro;yakakwira kabhoni simbi-kabhoni yemukati kazhinji yakakura kupfuura 0.60%.Mhando iyi yesimbi haiwanzo shandiswa mukugadzira pombi dzesimbi.
Hapana kujeka kwehasha, kushanduka kudiki panguva yekudzima, kuneta kwakanyanya uye kuwanda kwemaitiro kuramba mushure mekudzima uye kudziya kurapwa, yakanaka kudzika-tembiricha kukanganisa kuoma, kukwira kwesimba uye simba risingaperi pakupisa kwakanyanya.Simbi kazhinji anoshandisa pamusoro quenching pashure quenching uye tempering sezvo kupisa kurapwa chirongwa.
42crmo chinhu chiri musimbi.Kare, zita resimbi.Iro zita nderekuti: Q345B, zvinhu zvakafanana ndeye Q345a, Q345c, Q345e, mhando yegiredhi chiratidzo ABCDE zvinoreva kuti tembiricha yekukanganisa haidiwe kuita +20 madhigirii 0 madhigirii -20 madhigirii 40 madhigirii ABCD inomiririra nhanho yemhando Q235 yemhando yepamusoro mapoinzi. Kune mazinga mana eA, B, C, D, kubva kuA kusvika kuD kuti mhando yacho kubva pasi kusvika kumusoro.
Zvinodiwa zvemhando dzakasiyana siyana ndezvizvi:
A——Ipa kemikari yeS, P, C, Mn, Si uye fu, fy, δ5 (δ10), maererano nezvinodiwa nemutengi, 1800 inotonhora bend test inogona kupihwa, asi hapana simba rekudzora simba, kabhoni. zvemukati uye manganese zvemukati hazvitariswe semamiriro ekutumira.
B——Ipa S, P, C, Mn, Si chemical composition uye fu, fy, δ5 (δ10), inotonhora yekupeta 180' bvunzo.Inopawo simba rekuita pa +200C, Ak≥27J
C-Kuwedzera kune zvakafanana zvinodiwa seKirasi B, inopawo simba rekuita Ak≥27J pa00C.
D----Kuwedzera kune zvinodiwa padanho B, inopawo simba rekuita Ak≥27J pa -200C.E----Kuwedzera kune zvinodiwa padanho B, inopawo simba rekuita Ak≥27J pa -400C.
Iko 42crmo seamless simbi mapaipi uye akajairwa simbi mapaipi anoshanda zvakateerana: Mapombi esimbi akakamurwa kuita inotonhora inodhonzwa uye inopisa yakakungurutswa.
