Kev cai Stainless hlau noj hmo phaj, cov cuab yeej hauv chav ua noj, sib sib zog nqus kos Stamping qhov chaw

I. Kev ua kom zoo tshaj plaws ntawm cov khoom vaj khoom tsev
Nqus quenching, los ntawm cua sov thiab txias ceev hauv ib qho chaw oxygen -dawb ib puag ncig, txo oxidation nto thiab decarburization ntawm lub workpiece, kom ntseeg tau lub hardness ntawm lub puab thiab toughness ntawm cov pwm. Cryogenic kev kho mob, los ntawm kev ua kom txias qeeb ntawm qhov kub thiab txias, hloov cov residual austenite hauv cov hlau mus rau hauv martensite, txhim kho cov khoom hardness thiab hnav tsis kam. Kev sib xyaw ua ke ntawm ob txheej txheem no optimizes tag nrho txhua yam khoom ntawm cov khoom pwm, ua kom muaj kev ruaj ntseg nyob rau hauv siab loads thiab siab zaus ntawm kev siv, thiab ncua kev pab cuam lub neej.

II. Txhim kho Surface Quality thiab Dimensional Stability

Nqus quenching tiv thaiv oxidation discoloration thiab quenching cov kab nrib pleb thaum lub sij hawm quenching txheej txheem, tuav lub smoothness ntawm daim tawv nqaij thiab qhov tseeb ntawm cov pwm. Cryogenic kev kho mob ntxiv tshem tawm cov kev ntxhov siab sab hauv, txo qhov kev pheej hmoo ntawm microcracks thiab deformation, kom ntseeg tau tias qhov zoo ntawm cov pwm nyob rau hauv thermomechanical kev nyuaj siab. Qhov kev tiv thaiv dual no txo ​​cov pwm txij nkawm ntau zaus thiab kev tsim khoom poob qis, txhim kho cov kab ntau lawm ruaj khov thiab kev lag luam zoo.

III. Optimization ntawm Internal Microstructure

Nqus quenching thiab cryogenic kho txhim kho cov microstructure sab hauv ntawm cov pwm. Nqus quenching xyuas kom zoo thiab cov hlau zoo li qub, txhim kho lub zog thiab toughness. Cryogenic kev kho mob txhawb kev ua tiav austenite hloov pauv, txo cov kev ntxhov siab seem, thiab tiv thaiv cov kab nrib pleb lossis pob txha hauv pwm vim muaj kev ntxhov siab sab hauv. Optimization ntawm sab hauv microstructure ua tiav cov kev ntxhov siab tsim nyog thiab kev tso tawm lub zog tsis sib xws, yog li txuas ntxiv tag nrho cov kev pabcuam lub neej ntawm pwm.
