Dab tsi yog qhov nruab nrab zaus hardening khoom rau hauv kab log?
Dab tsi yog qhov nruab nrab zaus quenching cov cuab yeej rau cov log tsheb? Ua ntej tshaj plaws, cia peb nkag siab tias lub log tsheb yog dab tsi. Lub log taug kev yog kev faib tawm ntawm forgings. Nws yog tsuas yog siv nyob rau hauv gantry cranes-chaw nres nkoj machinery-bridge cranes-mining machinery, thiab lwm yam. Nws yog ib qho yooj yim heev puas qhov chaw yuav tsum tau quenched los txhim kho lub toughness, tej yam kuj thiab tawg tsis kam ntawm lub log lawv tus kheej.
Intermediate zaus hardening khoom rau tsav tsheb log yog ib qho induction hardening khoom tshwj xeeb uas tsim los rau hardening lub log tsav. Cov khoom tseem ceeb yog cov khoom siv hluav taws xob nruab nrab, lub tshuab ua kom tawv tawv thiab lub tshuab ua kom txias. Qhov nruab nrab zaus electromagnetic induction cua sov txoj cai yog siv los ua kom tawv tawv ntawm lub log tsav. Txhawm rau kom ntseeg tau tias lub log tsis sib xws, cov txheej txheem quenching yuav tsum ua kom tiav nrog kev pab ntawm cov cuab yeej. Lub luag haujlwm ntawm cov cuab yeej yog ua kom cov log ua axial tig ntawm ib qho kev sib hloov ceev. Kev sib hloov tuaj yeem hloov kho raws li qhov loj thiab qhov xav tau ntawm lub log.
Kev xav tau ntawm cov khoom siv nruab nrab zaus hardening rau kev tsav tsheb:
1. Lub hom phiaj: Kev sib hloov quenching ntawm lub puab zawj ntawm lub log.
2. Khoom siv: casting.
3. Qhov tob ntawm quenching txheej: 2-7mm.
4. Quenching txoj kab uas hla: lub puab zawj ntawm lub log.
5. Quenching hardness: 45-56HRC.
6. quenching txoj kev: scanning quenching.
7. Txoj kev ua kom txias: kaw ob lub voj voog (lossis siv lub pas dej qhib thiab lub twj tso kua mis kom ntws dej).
