A36 simbi ndirondeimwe yesimbi yakajairika, wakamboziva nezvayo here?
Zvino nditevere parwendo rwekutsvaga nezve A36 simbi!
ASTM-A36 simbi ndiro iAmerican standard carbon structural simbi inogadzirwa zvinoenderana neASTM zviyero.A36 kabhoni simbi coil makemikari kuumbwa uye michina zvivakwa zvinoenderana neAmerican ASTM zviyero.Kupisa kutenderedza kunoshandiswa seyakanyanya kuburitsa nyika, uye ukobvu hwekugadzira huri pakati pe2mm ne400mm.Izvo zvinodiwa zvehunyanzvi zvemahwendefa esimbi zvinogona kureva iyo A578 American yekuonekwa kwekukanganisa chiyero.Kune matatu matatu ekuona kukanganisa mazinga A, B, C uye A435 level yekuona kukanganisa.A36 inopisa yakakungurutswa simbi inoshanda yakagadzikana pakugadzirwa.A36 inopisa yakakungurutswa simbi ndiro ine yakanaka mechanical zvivakwa, welding performance uye corrosion resistance, uye inoshandiswa zvakanyanya mukuvaka, mabhiriji, kugadzira michina nemimwe minda.
ASTM-A36 imhando yekabhoni simbi ine makemikari anoumbwa anonyanya kuumbwa nekabhoni (C), silicon (Si), manganese (Mn), phosphorus (P), sarufa (S) nezvimwe zvinhu.Pakati pavo, kabhoni ndiyo chinhu chikuru, uye basa rayo nderekuwedzera simba uye kuoma kwesimbi.Silicon uye manganese zvinhu zvinosanganisa izvo zvinowedzera kuwedzera kusimba uye kuoma kwesimbi.Phosphorus nesarufa zvinhu zvisina kuchena.Kuvapo kwavo kunoderedza kuomarara uye kushorwa kwesimbi, saka zvirimo zvinoda kunyatsodzorwa panguva yekugadzira.
C: ≤0.25%
Si: ≤0.4%
Nhamba: ≤0.8-1.2%
P: ≤0.04%
S: ≤0.05%
Kuwedzera: ≤0.2%
ASTM-A36 ine yakanakisa mechaniki zvivakwa, zvinosanganisira kusimba kwepamusoro, kusimba kwepamusoro, kunaka kwepurasitiki uye kugadzirisa zvivakwa.Kusimba kwayo i160ksi (1150MPa), goho simba i145ksi (1050MPa), kureba i22% (2-inch gauge), uye kuderera kwechikamu i45%.Aya ma mechanic properties anopa ASTM-A36 yakakwira-kuremerwa simba uye seismic kuramba mune dzakasiyana siyana engineering maapplication.
Goho simba——≥360MPa
Kusimba kwesimba——400MPa-550MPa
Elongation mushure mekuzorora--≥20%
Iyo nzira yekugadzira yeA36 simbi ndiro inonyanya kusanganisira kuenderera mberi kukanda, kupisa kutenderera, kutonhora kukungurukira, annealing uye mamwe maitiro.Kutanga, zvigadzirwa zvakanyungudutswa musimbi mabheti pakupisa kwakanyanya, uye zvino zvinoramba zvichikandwa kuti uwane ingots dzesimbi.Zvadaro, ingot yesimbi inopisa yakakungurutswa uye inotonhora yakakungurutswa kuti iwane ndiro yesimbi ine zvinodiwa.Pakupedzisira, ndiro yesimbi inonyungudutswa kubvisa kushushikana kwemukati uye kuvandudza michina yemagetsi uye kugadzikana kwesimbi ndiro.Mukuwedzera, kuitira kuti uvandudze kunaka kwepamusoro uye kunyatsojeka kweplate yesimbi, maitiro akadai sekugadzirisa, kutwasanudza, uye kucheka kwakanyatsodiwa kunodiwawo.Inogona kubudisa A36 carbon steel coil, A36 checkered plate, A36 inopisa yakaputirwa ndiro yesimbi etc.
ASTM-A36 simbi mahwendefa anoshandiswa zvakanyanya munzvimbo dzakasiyana dzeinjiniya, sekuvaka, mabhiriji, kugadzira michina, nezvimwe.
Mundima yekuvaka, ASTM-A36 simbi mahwendefa anoshandiswa kugadzira akasiyana zvivakwa zvekuvaka, senge pekugara, zvivakwa zvehofisi, mashopu, nezvimwe.
Mumunda wemabhiriji, ASTM-A36 simbi mahwendefa anoshandiswa kugadzira zvimiro zvakakura zvemabhiriji, senge mabhiriji emigwagwa, mabhiriji enjanji, nezvimwe.
Mumunda wekugadzira michina, ASTM-A36 simbi mahwendefa anoshandiswa kugadzira akasiyana emakanika masisitimu zvikamu, senge zvekuchera, cranes, michina yekurima, nezvimwe.
Nekuvandudzwa kwehupfumi uye nekukasira kwemaguta, kudiwa kweA36 simbi mahwendefa mukuvaka, mabhiriji nemimwe minda kucharamba kuchiwedzera.Mune ramangwana, nekuenderera mberi kwekuvandudzwa kwekuziva kwezvakatipoteredza, tarisiro yemusika yeASTM-A36 mahwendefa esimbi ichave yakakura.Muminda yakadai semotokari dzemagetsi matsva uye kugadzirwa kwemagetsi emhepo, kudiwa kweASTM-A36 mahwendefa esimbi kucharamba kuchikura.Pamusoro pezvo, sezvo nyika iri kuramba ichiisa mari mukuvaka zvivakwa, kudiwa kweASTM-A36 mahwendefa esimbi mukuvaka, mabhiriji nemimwe minda kucharamba kuchikura.Naizvozvo, ASTM-A36 simbi ndiro ine yakafara musika tarisiro uye yakakwirira mari kukosha.
A36 simbi ndiro inonyanyo shandiswa kabhoni structural simbi ndiro ine yakanakisa mechanical zvivakwa, welding performance uye corrosion resistance.
Minda yayo yekushandisa inovhara kuvaka, mabhiriji, kugadzira michina uye mamwe minda.
Mune ramangwana, nekuenderera mberi nekuvandudzika kwekuziva kwezvakatipoteredza uye kuvandudzwa kwemotokari dzesimba idzva, simba remhepo uye mamwe minda, tarisiro yemusika yeASTM-A36 mahwendefa esimbi ichave yakakura.
Naizvozvo, kune vanoisa mari, ASTM-A36 ine yakakwira kukosha kwekudyara.
Panguva imwecheteyo, yeinjiniya madhizaini ekugadzira uye vagadziri, ASTM-A36 zvakare iri yemhando yepamusoro zvinhu inofanirwa kusarudzwa.
Ndinovimba kuti chinyorwa ichi chinobatsira kwauri.
Kana iwe uchida kuona imwe sainzi yakakurumbira, ndapota teerera kune ino webhusaiti.
