Dab tsi yog cov khoom siv rau forging?

Forging yog cov txheej txheem tsim khoom siv dav siv los tsim cov hlau nyob rau hauv siab. Nws yog lub npe hu rau kev tsim cov khoom muaj zog, txhim khu kev qha, thiab cov khoom tsis zoo-tiv taus uas yog qhov tseem ceeb hauv kev ua haujlwm siab xws li tsheb, aerospace, roj thiab roj, kev tsim kho, thiab tshuab. Txawm li cas los xij, tsis yog tag nrho cov hlau yog tsim rau forging.

Covcov ntaub ntawv siv rau forgingyuav tsum muaj kev sib xyaw ua ke ntawm lub zog, ductility, thermal stability, thiab machinability kom tau raws li qhov xav tau ntawm cov txheej txheem thiab daim ntawv thov zaum kawg. Kab lus no tshawb txog cov khoom siv forging ntau tshaj plaws, lawv cov khoom tseem ceeb, thiab vim li cas lawv raug xaiv rau kev lag luam sib txawv thiab ib puag ncig.
