Ko 45# simbi inoda kudzikamiswa?
Ko 45# simbi inoda kudzikamiswa?
Kudiwa kwekuwedzera kushatirwa kunotsanangurwa nemamiriro acho ezvinhu. Kana tembiricha yakasara ichikwanisa kudzorwa panguva yekudzima, hapana chikonzero chekuwedzera kudzika-tembiricha.
Chimiro uye zvimiro zve 45 # simbi mushure mekuvhara, normalizing, quenching uye tempering.
45# simbi inopinza: ferrite + pearlite;
45# simbi normalizing: ferrite + pearlite;
45# simbi inodzima: martensite;
45 # simbi inopisa: tempered martensite (yakaderera tembiricha tempering), tempered troostite (yepakati tembiricha tempering), tempered sorbite (yakanyanya tembiricha tempering).
Chimiro che45 # simbi mushure me normalizing ndeye ferrite + pearlite chimiro, chimiro mushure mekudzima martensite chimiro, uye iyo chimiro mushure mekudzima + 400 ℃ kushatirwa kudzikamisa troostite chimiro. Iyo inojairisa kuita kuomarara ishoma pane HB200, asi zvinhu zviri nyore kugadzirwa, inova ndiyo huru hurongwa hwekuita. Kudzima +400 ℃ kupisa kuoma kwakanaka kwazvo, pamusoro peHB300.
Kuomarara kwe45# simbi yakadzimwa uye yakapfava iri pakati peHRC20~HRC30;
Iyo yekudzima kuoma kwe45 # simbi iri pakati peHRC55 ~ 58, uye kukosha kunogona kusvika HRC62;
Zvinotora mazuva 15-20 kuti 45# simbi ishandiswe nekuti inoda kurapwa kwekuchembera kudzikamisa kushanda kwesimbi.
Hukukutu hwepamusoro-soro mukushandisa iHRC55 (high-frequency quenching HRC58).
45# simbi ndeyepamusoro-mhando kabhoni structural simbi ine yakaderera kuoma uye nyore kucheka kugadzira. Inowanzoshandiswa mu molds sema templates, matipi, magwara ekutungamira, nezvimwe, asi kupisa kurapwa kunodiwa.
