Kune akawanda marudzi esimbi pamusika, uye ss400 imwe yacho.Saka, rudzii rwesimbi SS400?Ndeapi marudzi akajairika esimbi?Ngatitarisei ruzivo rwakakodzera pakarepo.
Nhanganyaya kune SS400 simbi ndiro
SS400 iJapan yakajairwa kabhoni structural simbi ndiro ine tensile simba re400MPa.Nekuda kweiyo ine mwero kabhoni yemukati uye yakanaka kuita kwese, simba, plasticity uye welding zvivakwa zvakanyatsoenderana, uye ine yakanyanya kushandiswa.SS400 simbi ndiro pachayo ine yakazara-yemhando yepamusoro zvivakwa senge kusimba kwepamusoro, kusimba kwepamusoro, kuramba kuneta, kupikisa kuramba, kupfeka kuramba, corrosion resistance, welding, uye nyore kugadzirisa.
SS400 inoshandisa choto chemagetsi kugadzira simbi.Inogadzirwa kubva kumarara simbi.Simbi yacho yakachena.Simbi ndiro ndiro yesimbi yakati sandara inodirwa nesimbi yakanyunguduka yotsikirirwa kana yatonhodzwa.Iyo yakati sandara uye ine rectangular, uye inogona kukungurutswa yakananga kana kutemwa kubva kune yakakura simbi mitsetse.Mahwendefa esimbi akapatsanurwa nekukora, mahwendefa esimbi matete <8 mm (yakanyanya kuonda i0.2 mm), mahwendefa esimbi ari pakati nepakati 8~60 mm, uye mahwendefa esimbi akawedzera 60~120 mm.
SS400 simbi ndiro giredhi chiratidzo
"S": inoratidza zuva nezuva ndiro yesimbi;
"S": inoratidza kuti ndiro yesimbi ndeye carbon structural steel;
"400": Inoratidza kusimba kwesimbi ndiro, muMPa.
SS400 simbi simbi yekumisikidza mwero: shandisa JIS G3101 chiyero.
SS400 simbi yekutakura ndiro mamiriro: Iyo ndiro yesimbi inounzwa mune inopisa-yakatenderedzwa mamiriro, uye mamiriro ekutumira anogona zvakare kutsanangurwa zvinoenderana nehunyanzvi zvinodiwa.
SS400 simbi ndiro ukobvu kutungamira kuita zvinodiwa: Z15, Z25, Z35.
SS400 simbi ndiro yekuona kukanganisa zvinodiwa: kutanga kuona, kuona kwechipiri, uye kuona kwechitatu.
SS400 simbi ndiro density: 7.85 / cubic mita.
SS400 simbi ndiro uremu gadziriso formula: ukobvu * upamhi * kureba * density.
Ndeupi musiyano uripo pakati peQ235 uye SS400 simbi mahwendefa?
1. SS400 yakaenzana neQ235 yenyika yangu (yakaenzana neQ235A).Zvisinei, pane misiyano muzviratidzo chaizvo.Q235 ine zvinodiwa zvemukati meC, Si, Mn, S, P nezvimwe zvinhu, asi SS400 inongoda S uye P kuti ive isingasviki 0.050.Iyo goho poindi yeQ235 yakakura kupfuura 235 MPa, nepo goho poindi yeSS400 iri 245MPa.
2. SS400 (steel for general structure) zvinoreva simbi yakajairika ine simba rekusimba rinopfuura 400MPa.Q235 zvinoreva yakajairwa kabhoni simbi ine goho rakakura kupfuura 235MPa.
3. Nhamba yepamusoro yeSS400 iJIS G3101.Nhamba yakajairwa yeQ235 ndeye GB/T700.
4. SS400 inzira yekumaka yesimbi yeJapan, inova iyo chaiyo yepamba Q235 simbi.Imhando yezvinhu zvesimbi.Q inomiririra kukosha kwechigadzirwa ichi, uye inotevera 235 inoreva kukosha kwechigadzirwa chechinhu ichi, icho chakapoteredza 235. Uye sezvo kuwanda kwezvinhu zvinowedzera, chibereko chayo chinoderera.Nekuda kweiyo ine mwero kabhoni yemukati uye yakanaka kuita kwese, simba, plasticity uye welding zvivakwa zvakanyatsoenderana, uye ine yakanyanya kushandiswa.
Chiyero chekushandisa cheSS400 simbi ndiro?
SS400 inowanzoshandiswa mu cranes, hydraulic presses, steam turbines, heavy industry machines and equipment, engineering michini nemidziyo, zvivako zvebhiriji, zvicherwa, maforklifts makuru, zvikamu zvemichina inorema, nezvimwewo SS400 mahwendefa esimbi anoshandiswawo zvakanyanya.
SS400 ine mwero kabhoni yemukati uye yakanaka kuita kwese, uye simba rayo, welding uye mapurasitiki zviri nyore, saka ine huwandu hwakanyanya hwekushandisa.Isimbi yakajairika muhupenyu hwedu uye inoshandiswa zvakanyanya mune mamwe matenga evagadziri 'mafuremu, Zvivako zvekuvaka senge simbi yemakona, kana pane mamwe midziyo yemotokari, inoshandiswawo pane mamwe mahigh-voltage transmission shongwe nemigwagwa mikuru, asi mashandisiro azvo haasi. inogumira kune izvi.Kazhinji, inoshandiswawo zvakanyanya mumashandisirwo apo zvido zvekushanda zvesimbi hazvisi zvakanyanya.
