1.Casting steel pob: tsawg chromium hlau, nruab nrab chromium hlau, siab chromium hlau thiab super siab chromium hlau (Cr12% -28%).
2.Forging steel pob: qis carbon alloy steel, nruab nrab carbon alloy steel, siab manganese steel thiab tsawg lub ntiaj teb chromium molybdenum alloy steel pob:
Tam sim no hom steel pob twg yog qhov zoo tshaj plaws? Tam sim no cia peb tsom xam:
1.High chromium steel zoo Performance index: chromium cov ntsiab lus yog ntau tshaj 10%, cov ntsiab lus carbon nyob rau hauv 1.80% -3.20% yog hu ua high chromium steel, qhov yuav tsum tau ntawm lub teb chaws tus qauv ntawm siab chromium pob hardness (HRC) yuav tsum yog ≥ 58, AK ≥ 3.0J / cm siab tus nqi ntawm
2.Low chromium steel zoo Performance index: nrog 0.5% ~ 2.5%, cov ntsiab lus carbon nyob rau hauv 1.80% -3.20% yog hu ua low chromium steel, cov kev cai ntawm lub teb chaws tus qauv uas tsis muaj chromium steel hardness (HRC) yuav tsum ≥ 45, AK ≥ 1.5J / cm Qhov cuam tshuam tus nqi ntawm 2, Rolling Ball txhawm rau kom ntseeg tau tias qhov zoo ntawm chromium steel pob kub kub tempering lossis kev co kev laus kho (kom tshem tawm kev ntxhov siab, xws li lub hom phiaj) ntawm steel pob nto yog tsaus liab los qhia tias cov khoom tau raug kub kub tempering kho, xws li lub pob steel pob yog cov xim hlau qhia cov khoom tsis muaj tempering.
3.Forged steel pob zoo Performance index: nrog 0.1% ~ 0.5% (forged steel pob tsis muaj chromium), cov ntsiab lus carbon hauv qab 1% thiab steel pob nrog kub forging manufacturing, ib co forged steel pob nto hardness (HRC) ≥ 56 ( Txawm hais tias nws tuaj yeem ua tiav ntau tshaj li quenching txheej tsuas yog 15 hli los yog li ntawd), steel ball vim yog forged steel pob khoom harden peev xwm core hardness feem ntau tsuas yog 30 degrees. Raws li ib txwm muaj, forged steel pob los ntawm kev kho dej quenching, forged steel pob tawg tus nqi siab.
4.Kev sib piv ntawm kev hnav tsis kam: super siab chromium steel> siab chromium steel> nruab nrab chromium steel pob> tsawg chromium steel> forged steel pob.
Cov ntsiab lus ntawm hnav-resistant steel pob:
Chromium cov ntsiab lus yog 1% - 3% thiab hardness HRC ≥ 45. Cov qauv no ntawm cov hlau tsis muaj steel pob yog hu ua low chromium alloy cam khwb cia pob. Tsawg chromium npas txais yuav qhov nruab nrab zaus hluav taws xob rauv, hlau pwm lossis xuab zeb casting hom. Nws qhov kev ua tau zoo yog tsim rau qee qhov metallurgical mines, slag thiab lwm yam lag luam, uas tsis tshua muaj kev sib tsoo raug thiab siv tsawg.
Wear-resistant steel pob cov ntsiab lus chromium yog 4% mus rau 6% thiab hardness HRC ≥ 47. Cov qauv no yog hu ua cov khoom siv ntau yam hlau, uas yog siab dua cov chromium hlau uas tsis tshua muaj kev xa mus rau lub zog thiab hnav tsis kam thiab. Chromium cov ntsiab lus yog 7% - 10% thiab hardness HRC ≥ 48 yog chromium alloy cam khwb cia khoom, uas nws cov kev ua tau zoo thiab lwm yam yog siab tshaj ntau yam hlau alloy steel pob.
Hnav-resistant steel pob cov ntsiab lus chromium ≥ 10% - 14% thiab hardness HRC ≥ 58. High chromium alloy cam khwb cia khoom yog ib hom hnav-resistant steel pob nrog siab siv tus nqi thiab kev ua haujlwm zoo hauv kev ua lag luam tam sim no. Nws daim ntawv thov ntau yog dav thiab yog siv nyob rau hauv metallurgy, xis mas, thermal zog, flue gas desulfurization, sib nqus cov ntaub ntawv, tshuaj, thee dej slurry twj tso kua mis; pob yog li ntawd, superfine hmoov, slag, ya tshauv, calcium carbonate thiab quartz-xuab zeb kev lag luam. Nws txoj haujlwm tseem ceeb tshwj xeeb tshaj yog nyob rau hauv kev lag luam cement, uas tuaj yeem nce ntau lawm thiab txo kev siv hluav taws xob.
