High-frequency induction cua sov tshuab rau txaj rail quenching txheej txheem

High-frequency induction cua sov tshuab rau nto hardening txheej txheem ntawm workpiece

①Npe ntawm high-frequency induction cua sov nto hardening ua hauj lwm daim CA6140 kws dhos txaj rail high-frequency hardening inductor qauv, cov khoom siv yog HT300.

②High zaus induction cua sov nto quenching tshav kub kev kho mob tej yam kev mob, nruab nrab zaus quenching hluav taws xob tsis: thawj voltage, 520V; cov kab tam sim no, 150A; thawj kauj hloov, 12 tig; thib ob coil tig, 120kW; Lub zog muaj zog, 90%.

③High-frequency induction cua sov nto quenching cua sov txheej txheem specification: a. Qhov sib txawv ntawm qhov inductor thiab cov lus qhia rail nto yog 1.5-2mm. b. Tsiv ceev 4mm / min. quenching kub 900 ℃. d. Quenching dej nruab nrab. e. Txias txoj kev: nruam txau.

④Intermediate zaus induction cua sov nto quenching cua sov txheej txheem tsom xam a. Hardness Tom qab high-frequency quenching, hardness mus txog 45 ~ 55HRC. b. Qhov tob ntawm txheej hardened yog 2 hli. c. Microstructure Txheej hardened yog cryptocrystalline thiab zoo koob zoo li martensite. Graphite. Muaj ib qho me me ntawm phosphorus eutectic yam tsis muaj txheej txheem hloov pauv. d. Khoov deformation, kev nyuaj siab nyob rau hauv nruab nrab yog tsawg dua los yog sib npaug li 0.5 hli.
