45#kuoma kwesimbi mushure mekudzima nekupisa

Kuomarara kwe45# simbi yakadzimwa uye yakadzikama zvikamu mushure mekudzima inofanira kusvika HRC56 ~ 59, uye mukana weiyo mikuru yepakati-chikamu yakaderera, asi haigone kuve yakaderera pane HRC48.

Kudzimwa uye kushatirwa 45 # simbi 45 # simbi isimbi yepakati-kabhoni structural simbi ine yakanaka inotonhora uye inopisa kushanda, yakanaka michina zvinhu, yakaderera mutengo uye yakafara masosi, saka inoshandiswa zvakanyanya. Utera hwayo hukuru ndehwekuti ine yakaderera kuomarara, mikuru yemuchinjikwa-chikamu uye yakakwira zvinodiwa zveworkpieces zvisina kukodzera kushandiswa.

Kudzima tembiricha ye45# simbi ndeye A3+(30~50) ℃. Mukushanda chaiko, muganho wepamusoro unowanzo kutorwa. Iyo yakanyanya kudzima tembiricha inogona kukurumidzira kupisa kweiyo workpiece, kuderedza oxidation yepasi, uye kugadzirisa kushanda zvakanaka. Kuti uite homogenize iyo austenite yebasa rekushanda, nguva yakakwana yekubata inodiwa. Kana iyo chaiyo yakawanda yevira yakaiswa yakakura, nguva yekubata inoda kuwedzerwa zvakakodzera. Zvikasadaro, panogona kuve nekusakwana kuomarara nekuda kwekudziya kusina kuenzana. Nekudaro, kana nguva yekubata yakarebesa, coarse zviyo uye yakakomba oxidative decarburization ichaitika zvakare.

Kudzima nekudzikamisa: Kudzima uye kudzikisira kurapa kwakapetwa kupisa kwekudzima uye kupisa kwekushisa kwakanyanya, uye chinangwa chayo ndechekuita kuti workpiece ive yakanaka yakazara michina michina. Simbi yakadzimwa uye yakapfava ine zvikamu zviviri: kabhoni yakadzimwa uye simbi inodziya uye alloy inodzimwa uye simbi yakapfava. Zvisinei nekuti iri kabhoni simbi kana alloy simbi, kabhoni yayo yemukati inodzorwa zvakanyanya. Kana iyo kabhoni yemukati yakanyanyisa, simba reiyo workpiece mushure mekudzima uye kupisa kwakakwira, asi kuoma hakuna kukwana. Kana iyo kabhoni yemukati yakadzikira, kuomarara kuchawedzera uye simba rinenge risina kukwana.
