Dab tsi yog Forging?

Kev ntaus nrigyog ib qho txheej txheem tsim khoom uas cuam tshuam nrog kev siv cov zog compressive hauv zos. Qhov no tuaj yeem ua tiav los ntawm kev rauj, nias, lossis dov - feem ntau nrog cov hlau nyob rau hauv lub xeev sov (tab sis khov kho). Forging txhim kho cov qauv noob sab hauv, txhim kho lub zog, thiab tshem tawm cov qhov tsis zoo xws li porosity lossis inclusions.

Kev forging tau hloov zuj zus mus rau ntau txoj kev nyob ntawm seb muaj dab tsi xws li kub, khoom siv siv, thiab kev teeb tsa pwm.

Kev faib tawm yooj yim ntawm Forging

Cov txheej txheem forging tuaj yeem faib ua pawg raws liob qho tseem ceeb:
