Tsib hom kev kho cua sov ib txwm muaj rau cov iav Forgings
Nov 07, 2024| Thaum twg cov iav zam txim tsim tawm, lawv feem ntau kho los ntawm kev kho cua sov, cua sov, cua txias. Lub ntsiab kev kho cua sov txoj kev kho cua sov yog tsib txoj hauv kev.
1. Nto Quenching ntawm cov iav Forgings: feem ntau siv rau cov hlau roj carbon thiab lwm yam steel, xws li cov hniav sib xyaw ua ke, cov hniav tawv tawv yog feem ntau {3}} hrc. Cov yam ntxwv tau muaj kev ua phem pitting kuj, siab anti-bonding muaj peev xwm thiab hnav tsis kam. Txij li cov hniav hniav tsis yog tawv, cov iav forging tseem muaj cov tawv muaj zog txaus kom tiv thaiv cov khoom loj me.
2. Carburizing thiab quenching ntawm cov iav forgings: feem ntau yog siv rau cov hlau tsis muaj zog thiab ua kom muaj zog ntawm cov hlau, thiab lwm yam. Cov khoom siv muaj zog thiab cov hniav hu rau lub zog ntawm lub iav forging yog siab, thiab cov coj tsis kam yog qhov zoo. Nws feem ntau siv nyob rau hauv cov iav kev sib kis tseem ceeb tuaj yeem cuam tshuam cov khoom siv. Tom qab carburizing thiab quenching, lub iav forgings muaj kev loj heev thiab yuav tsum muaj av.
3. Nitriding ntawm cov iav Forgings: Nitriding yog kev kho cov tshuaj tua cua sov. Tsis muaj lwm yam kev kho cua sov yuav tsum tau tom qab nitrival, thiab hniav tawv tawv muaj peev xwm mus txog {{1} hv. Txij li thaum lub zog tom qab nitriding muaj kev nyuaj siab, cov txheej txheem qis thiab muaj lub zog me me, lawv yog qhov tsim nyog rau lub zog sab hauv thiab lub zog uas tsis yooj yim los zom. Lawv feem ntau siv rau nitriving steel muaj alloy ntsiab xws li chromium, tooj thiab txhuas thiab xws li 38crmoala.
4. Tempering ntawm cov iav Femings: Feem ntau siv rau cov hlau roj carbon thiab lwm yam lossis siv cov roj ntsha tsis zoo, thiab lwm yam. Hniav Vim tias lub hardness tsis yog siab, tag nrho ntawm cov iav Finings tuaj yeem nqa tawm tom qab kev kho cua sov.
5. Kev ua li cas ntawm cov iav kev lom zem: Kev ua haujlwm ib txwm tuaj yeem tshem tawm sab hauv kev ntxhov siab hauv sab hauv, kho kom zoo, thiab txhim kho cov khoom siv txhua yam thiab txiav kev ua haujlwm. Iav Forgings nrog cov kev ua haujlwm muaj zog tsawg dua nrog cov pa roj carbon steel, thiab cov kab uas hla loj uas muaj cov hlau cam.
