Maitiro ekuita metallographic ongororo mushure mekudzima mu induction yekupisa choto?
Maitiro ekuita metallographic ongororo mushure mekudzima mu induction yekupisa choto?
Metallographic kuongororwa kwe pearlite ductile iron zvikamu mushure induction kupisa chira kudzima kuchaitwa zvinoenderana neJB/T 9205-2008 “Induction heat furnace quenching metallographic examination of pearlite ductile iron parts”
1) Mushure mekunge pearlitic ductile iron castings yadzimwa mune yakakwirira- uye yepakati-frequency induction yekupisa mavira uye yakaderera-tembiricha kudziya (W200T), metallographic samples inotorwa pakati peiyo induction quenching zone kana panzvimbo inotsanangurwa nehunyanzvi. mamiriro.
2) Mushure mekugaya, sampuli ye metallographic inoiswa nedoro solution ine 2% kusvika 5% nitric acid nehuwandu kusvikira chidimbu chakaoma chakaoma chinoratidzwa.
3) Zvinoenderana neiyo microstructure classification mirairo inoratidzwa muTable 6.2 uye microstructure classification chati muJB/T 9205-2008, ita metallographic evaluation. Pakati pavo, giredhi 3 kusvika 6 vanokwanisa; kana paine zvakakosha zvinodiwa, zvichaitwa zvinoenderana neakakodzera magwaro ehunyanzvi.
Tafura 6-2 Tsanangudzo ye microstructure classification ye pearlite ductile iron castings mushure mekudzima mu induction yekupisa vira.
| Level/level | Hunhu hwesangano |
| 1 | Coarse martensite, hombe yakachengetwa austenite, ledeburite, spheroidal graphite |
| 2 | Coarse martensite, hombe yakachengetwa austenite, spheroidal graphite |
| 3 | Martensite, yakakura yakachengetwa austenite, spherical graphite |
| 4 | Martensite, shoma shoma yakachengetwa austenite, spheroidal graphite |
| 5 | Fine martensite, spherical graphite |
| 6 | Fine martensite, shoma shoma ye ferrite isina kunyungudika, spheroidal graphite |
| 7 | Fine martensite, shoma shoma yepearlite isina kunyungudika, isina kunyungudutswa ferrite, spherical graphite |
| 8 | Fine martensite, yakawanda isina kunyungudika pearlite, isina kunyungudutswa ferrite, spherical graphite |
