1.Casting steel pob: tsawg chromium steel, nruab nrab chromium steel, siab chromium steel thiab super chromium steel (CR12% -28%).
2. Cov pob hlau steel: cov roj av tsis tshua muaj roj av, nruab nrab cov roj av hlau, cov hlau mangorgese siab chromium molybdenum alloy steel pob:
Tam sim no qhov twg ntawm cov pob zeb yog qhov zoo tshaj plaws? Tam sim no Wb Kev Ntsuam Xyuas:
1.Hog chromium cov khoom siv hluav taws xob zoo tshaj 10%, cov pa roj carromium ntawm lub teb chaws lub siab (HRC) yuav tsum yog high
2.low chromium cov khoom siv hlau nplaum steel: nrog 0.5% ~ 2.5%, cov khoom siv roj carbon monoxide qis (HRC ≥ 1.59 / cm Lub hom phiaj) ntawm cov pob zeb steel yog xim tsaus nti kom pom tias cov khoom kub kub yog cov xim hlau saum npoo yog cov xim hlau ua kom pom cov khoom uas tsis muaj qhov tempering.
3.Qhov chaw hlau pob khoom zoo: nrog 0.1% ~ 0.5% (ib co forged steel pob khoom muaj peev xwm ua kom muaj peev xwm quenching steel tawv yog feem ntau tsuas yog 30 degrees. Nyob rau hauv ib txwm muaj xwm txheej, forged steel pob los ntawm dej quenching kev kho mob, forged steel pob tawg lawm.
4.Comparison ntawm hnav tsis kam: Super Chromium Hlau> Cov Chromium Steel> Nruab Chromium Steel Pob> Cov Chromium Pob Hlau> Forged Steel Pob.
Cov ntsiab ntawm hnav-resistant steel pob:
Chromium cov ntsiab lus yog 1% - 3% thiab lub hardness HRC ≥ 45. Tus txheej txheem ntawm cov roj-resistant steel pob yog hu ua chromium alloy cam khwb cia pob. Cov khoom siv chromium tsawg yuav los txais yuav cov ntu nruab nrab ntau zaus cov tshuab hluav taws xob ntau dua, cov pwm hlau lossis xuab zeb casting hom. Nws cov kev ua tau zoo yog tsim nyog rau qee cov mettallurgical mines, slag thiab lwm yam kev lag luam, uas yog cov kev sib tsoo uas tsis tshua muaj kev sib tsoo.
Hnav cov hlau tiv thaiv lub pob hluav taws xob yog 4% rau 6% thiab hardness hrc ≥ 47. Tus qauv no yog siab dua li cov chromium steel tau hais txog lub zog thiab hnav tsis kam thiab. Chromium cov ntsiab lus yog 7% - 10% thiab lub hardness HRC ≥ 48 yog chromium alloy cam khwb cia khoom, uas muaj lwm yam kev ua tau zoo tshaj li ntau alloy steel pob siab.
Hnav-resistant steel pob cov ntaub ntawv chromium ≥ 10% thiab lub hardness hrc ≥ 58. Tus nqi zoo nkauj thiab tus nqi zoo hauv kev ua lag luam tam sim no. Nws daim ntawv thov ntau yog dav thiab siv hauv Metallurgy, Caas, Flue Khoom Siv Desulfurization, Cov Khoom Sib Nqus, Tshuaj Lom Zem, Tshuaj Lom Zem Dej; Pob yog li ntawd, superfine hmoov, swb tshauv, calcium carbonate thiab quartz-xuab zeb kev lag luam. Nws cov haujlwm yog qhov tseem ceeb tshwj xeeb hauv kev lag luam cement, uas tuaj yeem ua rau kev tsim khoom thiab txo kev siv zog.
