Kev txhais ntawm riam ntaub ntawv .: ib tapered ntaub ntawv nrog daim duab peb sab hla ntu qhia tias ntawm a riam hniav.
Ib sab ntawm no, cov ntaub ntawv Steel puas zoo rau riam?
Qhov sib tov no tuaj yeem ua rau ib qho riam zoo hniav. Txawm li cas los xij, qee qhov cov ntaub ntawv tsuas yog cov ntaub ntawv hardened me ntsis hlau , thiab hauv qab cov hniav tawv yog mos un-hardenable hlau . Hom zoo cov ntaub ntawv , zoo li Nicholson Cov ntaub ntawv , yuav nyuaj hlau tag nrho txoj kev los ntawm.
Dab tsi yog qhov txawv ntawm cov ntaub ntawv ntoo thiab cov ntaub ntawv hlau? Cov rau txiav ntoo hu ua ntoo -, txee- lossis tus qauv tsim cov ntaub ntawv . Mill cov ntaub ntawv tuaj yeem siv los ua kom zoo ntoo (lawv ua tau zoo tshaj plaws ntawm hardwood); txawm li cas los xij, cov ntaub ntawv ntoo yuav tsis siv rau hlau . Cov ntaub ntawv duab plaub hauv cross section hu ua tiaj cov ntaub ntawv . Cov no yog siv los tsim thiab du tiaj tus.
Tib neeg kuj nug, koj puas yuav tsum tau kho cov ntaub ntawv riam?
Yog lawm muaj ua kub kho . Txawm li cas los xij, qee cov neeg yuav anneal lawv kom lawv softer yog li lawv ua tau ua hauj lwm lawv yooj yim dua. Ib zaug lawv' ua ve profiled cov ntaub ntawv tawm, lawv mam li yuav muaj mus "reharden" nws, uas txhais tau tias lawv yuav xav tau rau HT nws dua.
