Txheej txheem cej luam ntawm Cov Hlau Txias Rolled

Cov kauj dov txias yog ua los ntawm cov kauj dov kub. Hauv cov txheej txheem dov txias, cov kauj dov kub raug dov qis dua qhov kub recrystallization, thiab cov hlau dov feem ntau raug dov ntawm chav tsev kub. Cov ntawv hlau nrog cov ntsiab lus silicon siab muaj qhov tsis tshua muaj brittleness thiab plasticity qis, thiab yuav tsum tau preheated rau 200 ° C ua ntej dov txias. Txij li thaum cov kauj dov txias tsis tau cua sov thaum lub sijhawm tsim khoom, tsis muaj qhov tsis zoo xws li pitting thiab hlau oxide uas feem ntau pom hauv kev dov kub, thiab qhov zoo ntawm qhov chaw thiab qhov tiav zoo.

Daim Ntawv Thov ntawm Cov Hlau Txias Rolled

Cov hlau dov txias muaj kev ua tau zoo, uas yog, los ntawm kev dov txias, cov hlau dov txias thiab cov hlau ntawv uas nyias dua thiab raug dua tuaj yeem tau txais, nrog kev ncaj siab, qhov chaw du siab, qhov chaw huv thiab ci ntawm cov hlau dov txias, thiab yooj yim txheej. Cov txheej txheem plated, ntau yam, siv dav, thiab cov yam ntxwv ntawm kev ua haujlwm siab thiab tsis laus, qhov taw tes qis, yog li cov hlau dov txias muaj ntau yam kev siv, feem ntau yog siv rau hauv tsheb, nruas hlau luam tawm, kev tsim kho, cov ntaub ntawv tsim kho, tsheb kauj vab, thiab lwm yam. Kev lag luam kuj yog qhov kev xaiv zoo tshaj plaws rau kev tsim cov hlau txheej organic.
