The phase transition tembiricha yepepa rendarirakubva α→α+ ε ingangoita 320 ℃, kureva, tembiricha yekudziya yakakwira kupfuura 320 ℃, chimiro chine chikamu chimwe-chikamu chimiro, kusvika chapisa kusvika 930 ℃ kana zvakadaro fluid chikamu chimiro, tichifunga nezvekushandiswa kwemidziyo, iyo dhigirii. ye oxidation ye workpiece mushure mekupisa uye iyo chaiyo yekugadzirisa ye workpiece mushure mekupisa kupisa uye zvimwe zvinhu.Iyo tembiricha yekudziya yakakwira zvakanyanya, iyo workpiece oxidation yakakomba.Iyo tembiricha yakanyanya kuderera, iyo workpiece simba uye elasticity yakakwira uye kuoma kuri pachena hakuna kukwana, haina kukodzera kuumba.
Nekuda kwehuwandu hukuru hwechoto, kuitira kuti iite dithermal uye kuwana rimwe simba uye kuomarara, kuitira kufambisa kunotevera kukotama kugadzirisa, imwe neimwe yevira workpiece kune tembiricha inoda kubata anenge 2h, ipapo inogona kunge isina chinhu inotonhora kurapwa, anogona zvakare kusiya workpiece mu tempering mbiya zvishoma nezvishoma kutonhora.Kazhinji, iyo yakagadziriswa workpiece inogona kuzivikanwa nenzira mbiri chete.Imwe ndeyekutarisa ruvara rweworkpiece, ndiko kuti, iyo yakagadziriswa workpiece kubva kune yepakutanga mhangura ruvara kune yebhuruu ruvara, nekuda kweoxidation uye pamusoro peiyo workpiece kugadzira 2 ~ 3μm gobvu oxide layer, nyore kudonha.
Chechipiri, workpiece inogona kugadziriswa zvakananga nekukotama kwemaoko kusarura.Kana uchikotama, kana uchinzwa kuti workpiece ine rimwe simba uye elasticity, asi zvakare inogona kukotama, ipapo annealing maitiro akanaka, akakodzera kugadzira kugadzirisa.Kusiyana neizvi, kusimba uye kusimba kweiyo workpiece mushure mekurapwa kwakakwira, uye hazvisi nyore kukotama neruoko, zvichiratidza kuti iyo annealing kurapwa mhedzisiro haina kunaka, uye inoda kuvharwa zvakare.
Kuti uwane chinangwa cheyunifomu tembiricha uye oxidation, tin bhuronzi sheet zvinhu workpiece kazhinji haina kukodzera kugadziriswa mubhokisi revira pasina kumhanyisa fan.Semuenzaniso, pasi pemamiriro ehuwandu hwevira, iyo workpiece inobatwa mubhokisi revira pasina kufambisa feni uye tsime revira nekukurudzira feni zvichiteerana.
Iyo tin bronze sheet workpiece inobatwa nebhokisi-mhando yevira ine kupenya kwakasiyana, kusimba kwepamusoro uye kusakwana kusimba, izvo zvakaoma kukotama uye kugadziriswa.Mushure mekurapwa kwechitubu chechoto cheiyo batch yebasa, kupenya kuri yunifomu, kusimba uye kusimba kwakakodzera, izvo zvinogoneka kune anotevera ekugadzirisa mabasa.
