Kana iyo idler assy yatonhodzwa, mitswe michena inowanzoumbwa pamusoro uye zvikamu zvitete.
Chimiro chemuromo muchena chakaoma uye chakaoma, chine hurombo hwekugadzirisa uye nyore kupepeta.
Naizvozvo, annealing (kana normalizing) inofanira kushandiswa kubvisa chena muromo tishu.Iyo annealing process ndeiyi: kudziyisa kusvika 550-950 ℃ kwemaawa maviri-5, ipapo kutonhora kwechoto kusvika 500-550 ℃ uyezve kutonhora kwemhepo.Munguva yekushisa kwakanyanya kwekubata nguva, iyo yepamusoro-tembiricha simenti uye eutectic cementite yakaora kuita graphite uye A, uye yechipiri cementite uye eutectoid cementite zvakare yakaora panguva yaitevera yekutonhora, zvichikonzera graphitization process.Nekuda kwekuparara kwecementite, kuoma kunoderera, nekudaro kuvandudza machinability.
Normalizing ye ductile iron
Chinangwa che ductile iron normalizing ndechekuwana pearlite matrix chimiro, kunatsa zviyo uye chimiro chakafanana, kuitira kuti uvandudze ma mechanic zvimiro zveDandong simbi castings.Dzimwe nguva normalizing zvakare kugadzirira ductile simbi pamusoro quenching pamusoro chimiro, normalizing inokamurwa kukwirira tembiricha normalizing uye yakaderera tembiricha normalizing.Iyo tembiricha yepamusoro yekujairira tembiricha kazhinji haipfuure 950 ~ 980 ℃, uye tembiricha yakaderera normalizing tembiricha inowanzodziya kusvika kune yakazara kupeta tembiricha ye820 ~ 860 ℃.Mushure mekujaira, vanhu vana vanowanzo fanirwa kubata nazvo kuti vabvise kushushikana kwemukati kunogadzirwa panguva yekujairira.
kuoma kwepamusoro
Kuti uvandudze kuomarara kwepasi, kupfeka kuramba uye kuneta simba kwemamwe magidhi mavhiri magungano, kudzima kwepamusoro kunogona kushandiswa.Zvose grey cast iron uye ductile iron castings inogona kuomeswa.Kazhinji, yakakwira (yepakati) frequency induction yekudziya yepasi yekudzima uye yemagetsi yekubata kumeso kudzima inoshandiswa.
Iyo bhokisi-mhando chimiro idler goko rakaumbwa uye rakakandwa nealkali phenolic resin jecha kana yemvura girazi jecha maitiro.Mushure meiyo matrix normalizing uye njanji yepakati frequency induction kudzima kupisa kurapwa, kuoma kwepasi kunosvika HRC48-58, uye kuomarara kudzika kuri pamusoro pe4-6mm (HRC45).Iyo ine kusimba kwekumira yakakwira mhedzisiro uye kupfeka kuramba nekuda kwemamiriro ekushanda akaomarara.
