Kuonekwa kwezvikanganiso zvesimbi yesimbi yeASTM-SA516Gr60Z35:
1. SA516Gr60 chiyero chepamusoro: American ASTM, ASME chiyero
2. SA516Gr60 ndeyemudziyo une simba rekupisa kwakaderera une ndiro yesimbi yekabhoni
3. Kuumbwa kwemakemikari eSA516Gr60
C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45.
4. Hunhu hweSA516Gr60 hwemakanika
Simba rekudhonza reSA516Gr60 re70,000 pounds/square inch, chinhu chikuru chiri mukati mayo C Mn Si ps control inosarudza mashandiro ayo. Zvimwe zvinhu zvishoma. Asme Standard Specification yemaplate esimbi yekabhoni emidziyo yekumanikidzwa kwepakati nepasi.
5. Mamiriro ekutumira eSA516Gr60
Plate yesimbi yeSA516Gr60 inowanzo kupihwa iri muchimiro chekutenderera, plate yesimbi inogonawo kugadziriswa kana kuderedzwa kwekushushikana, kana kuderedzwa pamwe nekuderedzwa kwekushushikana.
SA516Gr60 ukobvu >40mm ndiro yesimbi inofanira kugadziriswa kuti ive yakajairika.
Kunze kwekunge zvataurwa neimwe nzira neanoda demander, ukobvu hweplate yesimbi ≤1.5in, (40mm), kana paine zvinodiwa zvekusimba zvakachekwa, hunofanira kugadziriswa.
6. SA516Gr60 inoshandiswa kugadzira mudziyo wekunamira we coil une layer imwe chete, mudziyo wekunamira we coil une layer yakawanda, mudziyo wekunamira we multi-layer yakawanda uye mamwe marudzi maviri nematatu emakontena nemidziyo yekumanikidza ine tembiricha yakaderera. Inoshandiswa zvakanyanya mumafuta, indasitiri yemakemikari, chiteshi chemagetsi, boiler nemamwe mabasa, inoshandiswa mukugadzira ma reactors, heat exchangers, separators, matangi espherical, matangi emafuta negasi, matangi egasi ane liquefied, boiler drum, liquefied petroleum steam cylinders, mapombi emvura ane pressure yakakwira, turbine volute nezvimwe zvishandiso nezvimwe zvinhu.
7. Kana austenite ikatonhodzwa zvishoma nezvishoma (zvakaenzana nekutonhodzwa kwechoto, sezvakaratidzwa paMufananidzo 2 V1), zvigadzirwa zvekushandura zvinenge zviri pedyo nechimiro che equilibrium, kureva pearlite neferrite. Nekuwedzera kwehuwandu hwekutonhodza, ndiko kuti, kana V3>V2>V1, kutonhora kwe austenite kunowedzera zvishoma nezvishoma, uye huwandu hwe precipitated ferrite hunowedzera zvishoma nezvishoma, nepo huwandu hwe pearlite huchiwedzera zvishoma nezvishoma, uye chimiro chinova chakanaka. Panguva ino, huwandu hushoma hwe precipitated ferrite hunonyanya kupararira pamuganhu wezviyo.
8. Saka, chimiro che v1 iferrite+pearlite; Chimiro che v2 iferrite+sorbite; Chimiro chidiki che v3 iferrite+troostite.
9. Kana mwero wekutonhodza uri v4, huwandu hushoma hwe network ferrite ne troostite (dzimwe nguva huwandu hushoma hwe bainite hunogona kuonekwa) hunokonzereswa, uye austenite inonyanya kushandurwa kuita martensite ne troostite; Kana mwero wekutonhodza v5 ukadarika mwero wekutonhodza unokosha, simbi inoshandurwa zvachose kuita martensite.
10. Kushandurwa kwesimbi ine hunyanza hwakafanana nesimbi ine hunyanza hwakafanana, nemusiyano wekuti ferrite inotanga kudonha muchikamu chechipiri uye cementite inotanga kudonha muchikamu chechipiri.
