Qhov zoo ntawm qhov kev sib tsoo tawm steel pob

Kev ua haujlwm tseem ceeb ntawm kev sib tsom tawm pob zeb yog npuaj, uas tuaj yeem ua cov khoom sib tsoo khoom, tsuas yog siv hauv mines, fais fab nroj tsuag thiab lwm cov teb. Raws li tus neeg siv, thaum nriav cov khoom no, koj yuav tsum xav txog nws cov cim zoo. Piv txwv, qhov zoo ntawm qhov qes-chromium pob ntawm lub pob zeb sib tsoo steel pob yog 0.5% mus 2.5% ntawm cov chromium cov ntsiab lus, thiab cov ntsiab lus ntawm cov roj yog 1.80% thiab 3.20%, uas yog hu ua qes-chromium pob. Kev mob siab (HRC) yog ≥45 lossis tshaj saud, thiab qhov txiaj ntsim zoo li yog ak. ≥1.5J / cm2.

Yuav kom ntseeg tau tias qhov kev sib txuas ntawm cov pob zeb sib tsoo, nyob rau hauv tus txheej txheem ntawm ntau lawm, kev kub siab yuav tsum tau kho kom tshem tawm txoj kev ntxhov siab. Piv txwv, lub pob zeb ntawm lub pob zeb yog maub liab los qhia tias cov khoom tau raug rau qhov kub thiab txias, xws li hlau pob. Ntawm qhov chaw tseem yog xim hlau, qhia tias cov khoom yog tsis tempered ntawm kev sov siab.

Nyob hauv kev sib tsoo tawm pob zeb, qhov yuav tsum ua kom zoo rau lub nruab nrab chrome pob yog qhov nyuaj qhov muag yuav tsum yog siab tshaj 47, thiab cov ntsiab lus ntawm chromium yog 3.0% rau 7.0%, cov ntsiab lus ntawm carbon yog nruab nrab ntawm 1.80% thiab 3.20%, thiab feem nqi yog ak ≥ 2.0. J / cm2. Rau cov khoom kub-chromium, chromium ntsiab lus yuav tsum yog ≥10.0%, cov ntsiab lus carbon yog nruab nrab ntawm 1.80% thiab 3.20%, cov hardness (HRC) yog ≥58 los yog ntau dua, thiab qhov feem cuam tshuam yog ak≥3.0J / cm2 .
