1: Dab tsi yog qhov sib txawv tseem ceeb ntawm kub-forged thiab txias- tsim kev tsheb ciav hlau?
Kub-forged clips (1,100-1,200 degree) pom cov qauv zoo tshaj plaws thiab kev qaug zog. Txias-tsim clips (chav kub) muaj nruj dua qhov ntev, tab sis yuav tsum tau muaj kev ntxhov siab- nyem annealing. Forging tso cai rau cov geometry nyuaj dua thaum txias - ua kom haum siab - ntim ntau lawm. Cov ntaub ntawv tawm los lub zog sib txawv los ntawm 15-20% ntawm cov txheej txheem. Feem ntau cov ntawv siv hnyav hnyav qhia cov clips kub-forged rau cov kav ntev.
2: Yuav ua li cas traceability nyob rau hauv clip manufacturing?
Txhua batch tau txais ib lub cim kub ntawm laser - cim rau clips. Mill test qhia cov ntaub ntawv tshuaj muaj pes tsawg leeg thiab cov khoom siv tshuab. Forging parameters raug kaw nyob rau hauv cov txheej txheem txheej txheem cav. Daim ntawv pov thawj zoo ua raws EN 10204 3.1 cov qauv. Blockchain systems tam sim no pab kom tag nrho lub neej taug qab.
3: Dab tsi ua rau clip nto decarburization thaum kho cua sov?
Oxidation ntawm qhov kub thiab txias tshem tawm cov pa roj carbon ntawm cov khaubncaws sab nraud povtseg (0.1-0.3mm tob). Kev tswj cua sov tsis txaus yog thawj qhov ua rau. Decarburization txo qhov tawv tawv los ntawm 10-15 HRC cov ntsiab lus. Tswj nitrogen / hydrogen atmospheres tiv thaiv qhov teeb meem no. Eddy kev ntsuam xyuas tam sim no pom cov chaw cuam tshuam tsis yog kev puas tsuaj.
4: Yuav ua li cas microalloying ntsiab (V, Nb, Ti) txhim kho clip kev ua tau zoo?
Vanadium ua cov carbide uas ua kom cov nplej loj (ASTM 8-10). Niobium nce qhov kub ntawm recrystallization thaum kub ua haujlwm. Titanium kho nitrogen kom tiv thaiv kev laus. Kev sib xyaw ua ke ua kom muaj zog tawm los ntawm 20-30%. Qhov zoo tshaj plaws piv yog 0.05-0.15% rau txhua yam.
5: Dab tsi yog cov txiaj ntsig ntawm isothermal quenching rau clip steel?
Austempering at 280-350°C produces bainitic microstructure. Achieves hardness of 45-50 HRC with superior toughness. Reduces quenching distortion compared to martensitic treatment. Particularly effective for thick-section clips (>14 mm). Txheej txheem yuav tsum tau ntsev da dej kub tswj.
