Qhov zoo ntawm High Strength thiab Hardness
Tom qab siab -kub forging, sab hauv siv lead ua qauv ntawm forgings tau zoo, yog li ua rau tag nrho cov neeg kho tshuab lub zog. Qhov kev txhim kho no tau cuam tshuam tsis yog hauv lub zog tensile nkaus xwb tab sis kuj nyob rau hauv lub zog compressive, lub zog tawm los, thiab lwm yam. Nyob rau tib lub sijhawm, forged workpieces kuj tau txais cov txiaj ntsig hardness siab dua, txhais tau tias lawv muaj peev xwm tiv taus rau sab nraud los yog hnav. Cov yam ntxwv no muab kev ruaj ntseg zoo rau kev siv forgings hauv siab -load ua haujlwm ib puag ncig.
Zoo heev hnav tsis kam
Piv nrog rau lwm yam castings los yog steel cov ntaub ntawv ntawm tib yam specifications, forgings ho txo nto roughness thiab tsawg pores. Qhov no yog vim hais tias cov txheej txheem forging tso cai rau cov hlau cov qauv fibrous mus txuas ntxiv txuas ntxiv thiab sib cuam tshuam, tsim kom muaj lub network ntom ntom ntawm cov ntaub so ntswg. Qhov kev hloov kho microstructural tsis tsuas yog txhim kho tag nrho cov rigidity ntawm lub workpiece tab sis kuj pab txhim kho nws cov hnav tsis kam ntawm qhov chaw sib cuag. Yog li ntawd, nyob rau hauv ntau daim ntawv thov uas yuav tsum tau hnav tsis kam, forgings yog ib qho ntawm cov khoom nyiam.
Zoo heev Plasticity thiab Toughness
Ntxiv nrog rau ob yam tseem ceeb uas tau hais los saum no, forgings kuj muaj cov yas siab thiab zoo heev toughness. Qhov no tso cai rau lawv kom yooj yim zoo li cov khoom siv complex, ua tau raws li ntau hom kev tsim qauv. Txawm tias tom qab muaj qhov kub thiab txias hloov los yog raug rau sab nraud quab yuam, forgings tuaj yeem tswj kev ncaj ncees thiab tsis tshua muaj kev tawg lossis deformation.
