Quenching txheej txheem cov ntsiab lus ntawm iav carburizing qhov chaw

quenching txheej txheem cov ntsiab lus ntawm iav carburizing qhov chaw yog raws li nram no:

1. Kev Npaj Nto: Cov khoom raug ntxuav kom huv si thiab degreased kom tshem tawm cov impurities thiab cov kab mob uas tuaj yeem cuam tshuam rau cov txheej txheem carburizing.

2. Carburizing: Cov khoom tom qab ntawd muab tso rau hauv qhov cub carburizing thiab ua kom sov rau qhov kub ntawm 850 degree txog 950 degree nyob rau hauv ib qho chaw ntawm hydrocarbon gas. Cov txheej txheem no diffuses carbon rau hauv qhov chaw ntawm qhov chaw thiab tsim cov txheej txheem carbon nplua nuj.

3. Quenching: Thaum cov khoom tau raug carburized, lawv tau txias sai heev uas siv cov quenching nruab nrab xws li dej, roj lossis polymer. Qhov kev xaiv ntawm quenching nruab nrab nyob ntawm qhov xav tau hardness thiab mechanical zog ntawm qhov chaw.

4. Tempering: Cov khoom yog ces tempered ntawm qhov kub ntawm 150 degree mus rau 600 degree kom txo cov hardness thiab brittleness tsim thaum lub sij hawm quenching txheej txheem, thaum tuav lub zog tsim nyog.

5. Txhaj Peening: Kev txhaj tshuaj peening feem ntau ua tom qab tempering los txhim kho cov khoom siv kho tshuab ntawm qhov chaw. Cov txheej txheem no suav nrog kev foob pob ntawm qhov chaw nrog cov hlau me me los tsim cov kev ntxhov siab uas txhim kho lub neej qaug zog thiab tiv thaiv kev tawg.

Los ntawm kev ua tib zoo tswj cov txheej txheem carburizing thiab quenching, iav carburizing qhov chaw tuaj yeem muab qhov tsim nyog hardness thiab hnav tsis kam tiv taus qhov xav tau ntawm cov ntawv thov hnyav.
