1. Kupisa tembiricha, kubata nguva uye kutonhora nzira: The phase shanduko tembiricha yendiro yendarira yeratakubva ku α→α+ε inenge 320 ℃, kureva kuti, tembiricha yekudziya yakakwira kupfuura 320 ℃, uye chimiro chayo ndechimwe-chikamu chimiro, kusvika chapisa kusvika 930 Iyo yemvura chikamu chimiro chinooneka chakatenderedza ℃.Tichifunga nezvemidziyo inoshandiswa, dhigirii ye oxidation yebasa mushure mekupisa, uye chaiyo yekugadzirisa mashandiro eiyo workpiece mushure mekupisa kupisa, mushure me-pa-site kuenzanisa uye kuongororwa, tembiricha yekudziya ye (350 ± 10) ℃ inonyanya kukodzera.Iyo tembiricha yekudziya yakakwira zvakanyanya, uye workpiece yakanyanyisa oxidized.
Kana kutonhora kwakanyanya kuderera, simba uye elasticity ye workpiece yakakwirira uye kuoma zviri pachena kuti hazvina kukwana, saka hazvina kukodzera kuumba.Nekuda kwekuwanda kwechoto kurodha (230kg / 35kW gomba choto), kuitira kuti iite kupisa uye kuwana imwe simba uye kuoma, kuitira kufambisa kunotevera kukotama kugadzirisa, maworkpiece muchoto chega chega anofanirwa kuchengetwa achidziya. kweanenge maawa maviri mushure mekusvika tembiricha.Inogona kunge yakatonhodzwa nemhepo, kana kuti workpiece inogona kusiiwa mubhodhoro rinopisa kuti itonhorere zvishoma nezvishoma.
2. Kuzivikanwa kwemhedzisiro yekurapa annealing: Nekuda kwemamiriro mashoma, nzira mbiri dzinogona kushandiswa kuona zviri nyore iyo yakarapwa workpiece.Imwe ndeyekucherechedza ruvara rwebasa rekushanda, ndiko kuti, iyo yakagadziriswa workpiece inoshanduka kubva kune yepakutanga yendarira ruvara kusvika kune yebhuruu-dema.Chechipiri ndechekuti iyo yakagadziriswa workpiece inogona kutongwa zvakananga nekuikotamisa neruoko.Kana uchikotama, kana workpiece inogona kukotamiswa iine rimwe simba uye elasticity, zvinoreva kuti annealing maitiro akanaka uye akakodzera kuumba.Pane zvinopesana, simba uye elasticity ye workpiece mushure mekurapwa kwakakwirira, uye hazvisi nyore kukotama nemaoko, zvichiratidza kuti annealing treatment effect haina kunaka, uye inoda kudzokororwa zvakare.
3. Zvishandiso nechoto chekurodha nzira: Kuti uwane chinangwa chekufanana kwekushisa uye anti-oxidation, tin bronze material workpieces kazhinji haakodzere kugadzirwa mumabhokisi evira pasina kumutsa mafeni.Semuenzaniso, pasi pemamiriro emuchoto mumwechete (simba rechoto 230kg / 35kW), iyo workpiece inobatwa mubhokisi revira pasina kufambisa feni uye gomba rinopisa moto rine feni inokurudzira, zvichiteerana.Pasi peiyo annealing process mamiriro ekudziya pa (350 ± 10) ℃, kubata kwe2h uyezve kutonhora kwemhepo, mhedzisiro yekurapa kuviri kwakasiyana.
Iyo workpieces inobatwa nebhokisi chevira ine kubwinya kwakasiyana, simba rakakwirira uye kusakwana kuoma, izvo zvakaoma kukotamiswa.Mushure mekugadzirisa batch imwechete yezvishandiso zvine gomba rinopisa moto, kubwinya kwakawedzera yunifomu, uye kusimba uye kuomarara kwakakodzera, izvo zvinogoneka kune anotevera ekugadzirisa mashandiro.Naizvozvo, kune mabhizinesi ane mamiriro mashoma, kurapwa kweannealing kunogona kugadziriswa nechoto chegomba, uye dhiri rinopisa rine huwandu hukuru rinogona kushandiswa pakuchaja.Iwo maworkpieces anofanirwa kuiswa zvakanaka kudzivirira deformation yeakadzika workpieces nekuda kwekumanikidza.
