Zvigadzirwa zvedu
Alloyed galvanized steel sheet
Rudzi urwu rwechigadzirwa runogadzirwa zvakare uchishandisa inopisa dip nzira, asi kana yabuda mutangi, inokurumidza kupiswa kusvika pa500 ℃ kugadzira firimu rakatetepa rezinc nesimbi.Iri pepa rakabatidzwa rine kunaka kwekubatisa kusimba uye kusimba.
Galvanized yekugadzira mutsara uchishandisa yakanyanya kukwirisa United States simbi yekugadzira simbi, iyo huru yakatarwa yechigadzirwa ndeye 0.15-1.5mm * 800 ~ 1250mm.Mutsetse wekugadzira wakashongedzerwa nemwaranzi yekuenderera mberi annealing vira;kudziyisa chubhu mhando horizontal jet frequency induction heat ceramic zinc poto;mana mhango mhepo banga;light machine;muchina wekutwasanura uye zvimwe midziyo yepamusoro, Isu takapayona nehunyanzvi hwepatent: tsvina yekushandisa kupisa mudziyo, inozochengetedza simba rakawanda uye kuchengetedza zvakatipoteredza.
Iyo zinc uye iron alloy layer inoumbwa mukuputira kwese nekupisa kurapwa kwesimbi tambo inopfuudza galvanizing yekugeza mvura.Iyo yekupfeka inotaridzika yakasviba grey isina metallic luster.Zviri nyore kuita hupfu panguva yekuumbwa kwechisimba.Inoshandiswa kune iyo yekuputira iyo inogona kuve yakapendwa pasina kumwe kurapwa kunze kwekunatswa kwese.
Iyo giredhi yeakaumbwa alloy simbi inomiririrwa nenhamba dzechiArab uye akajairwa kemikari element zviratidzo.Nhamba mbiri dzechiArab dzinoshandiswa kumiririra zvinoreva kabhoni yemukati (x/10000) nenzvimbo kumusoro kwegiredhi.The
zvemukati zvealloying zvinhu zvinomiririrwa sezvizvi: Kana avhareji yemukati iri pasi pe1.50%, nhamba yegiredhi inongoratidza chinhu uye kazhinji hairatidze zviri mukati;Kana avhareji yemukati iri 1.50%～2.49%, 2.50%～3.49%, 3.50%～4.49%, 4.50%～5.49%, 2, 3, 4 uye 5 inonyorwa ichitevera maalloying elements.Semuyenzaniso: Avhareji yemukati kabhoni, chromium, manganese uye silicon yezvimiro alloy simbi ndeye 0.30%, 0.95%, 0.85% uye 1.05%.Kana S uye P zvemukati zviri ≤0.035%, giredhi rinoratidza "30CrMnSi".High-grade quality structural alloy steel (S uye P zvinyorwa ≤0.025%) inoratidzwa nekuwedzera "A" kugiredhi.Somuenzaniso: "30CrMnSiA".Super-grade quality structural alloy steel (S≤0.015%, P≤0.025%) inoratidzwa nekuwedzera "E" kugiredhi.Somuenzaniso: "30CrM nSiE".Iyo giredhi yeakakosha alloy simbi ichawedzera chiratidzo chinoratidza chigadzirwa chinangwa muTafura 1 kumusoro wegiredhi (kana muswe).Semuenzaniso, giredhi re30CrMnSi simbi yeriveting screw inoratidzwa seML30CrMnSi.2. Iyo inomiririra nzira ye alloy spring steel giredhi yakafanana neiyo structural alloy simbi.Semuenzaniso: Avhareji yemukati kabhoni, silicon uye manganese i0.60%, 1.75% uye 0.75% yechirimo simbi uye giredhi inomiririrwa se "60Si2Mn".Kune yepamusoro-giredhi yemhando yechitubu simbi, chiratidzo "A" chinowedzerwa kugiredhi uye giredhi rinomiririrwa se "60Si2MnA".
