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: tsawg carbon alloy steel, nruab nrab carbon alloy steel, siab manganese hlau thiab tsawg lub ntiaj teb chromium molybdenum alloy steel pob:
Tam sim no hom hlau pob twg zoo tshaj? Tam sim no cia peb tsom xam:
1. Cov ntsuas zoo ntawm cov hlau chromium siab: cov ntsiab lus chromium ntau dua 10%, cov ntsiab lus carbon hauv 1.80% -3.20% hu ua cov hlau chromium siab, cov kev cai ntawm tus qauv hauv tebchaws ntawm cov chromium pob hardness siab (HRC) yuav tsum yog ≥ 58, AK ≥ 3.0J / cm qhov cuam tshuam tus nqi ntawm
2. Cov ntsuas zoo ntawm cov hlau chromium qis: nrog 0.5% ~ 2.5%, cov ntsiab lus carbon hauv 1.80% -3.20% hu ua cov hlau chromium qis, cov kev cai ntawm lub teb chaws tus qauv qis chromium steel hardness (HRC) yuav tsum yog ≥ 45, AK ≥ 1.5J / cm qhov cuam tshuam ntawm 2, Rolling Ball kom ntseeg tau tias qhov zoo ntawm cov hlau chromium qis kub tempering lossis kev laus kev kho mob (txhawm rau tshem tawm kev ntxhov siab casting, xws li lub hom phiaj) ntawm cov hlau pob nto yog tsaus liab los qhia tias cov khoom tau ua qhov kub siab tempering kho, xws li cov hlau pob nto yog xim hlau qhia cov khoom tsis muaj tempering.
3. Cov ntsuas zoo ntawm cov pob hlau forged: nrog 0.1% ~ 0.5% (cov pob hlau forged tsis muaj chromium), cov pa roj carbon tsawg dua 1% thiab cov pob hlau nrog kev tsim khoom kub siab, qee qhov forged steel pob qhov nyuaj ntawm qhov chaw (HRC) ≥ 56 (txawm hais tias nws tuaj yeem ua tiav ntau dua li quenching txheej tsuas yog 15 hli lossis li ntawd), pob hlau vim yog cov khoom siv forged steel pob hardening muaj peev xwm core hardness feem ntau tsuas yog 30 degrees. Nyob rau hauv cov xwm txheej 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 hlau> siab chromium hlau> nruab nrab chromium hlau pob> qis chromium hlau> forged hlau pob.
Cov ntsiab lus ntawm cov hlau uas tsis yooj yim hnav:
Cov ntsiab lus chromium yog 1% - 3% thiab qhov nyuaj HRC ≥ 45. Tus qauv ntawm cov hlau uas tsis yooj yim hnav no hu ua cov pob chromium alloy cast ball qis. Cov pob chromium qis siv cov cua sov hluav taws xob nruab nrab zaus, pwm hlau lossis hom casting xuab zeb. Nws cov kev ua tau zoo yog qhov tsim nyog rau qee qhov chaw tsuas hlau, slag thiab lwm yam lag luam, uas muaj qhov tseeb sib tsoo tsawg thiab siv tsawg.
Cov pob hlau uas tsis hnav tau cov chromium yog 4% txog 6% thiab qhov nyuaj HRC ≥ 47. Tus qauv no hu ua cov pob hlau ntau yam, uas siab dua li cov hlau chromium qis uas hais txog lub zog thiab kev tiv thaiv kev hnav. Cov ntsiab lus Chromium yog 7% - 10% thiab qhov nyuaj HRC ≥ 48 yog cov pob hlau chromium alloy, uas nws cov kev ua tau zoo thiab lwm yam siab dua li cov pob hlau ntau yam siab.
Cov pob hlau uas tiv taus hnav muaj cov chromium ntau dua ≥ 10% - 14% thiab qhov nyuaj HRC ntau dua ≥ 58. Cov pob hlau uas muaj chromium ntau yog ib hom pob hlau uas tiv taus hnav uas muaj tus nqi siab thiab ua tau zoo hauv kev ua lag luam tam sim no. Nws siv tau dav hauv metallurgy, cement, thermal power, flue gas desulfurization, magnetic materials, chemical, thee dej slurry pump; yog li ntawd, pob, superfine hmoov, slag, fly ash, calcium carbonate thiab quartz-xuab zeb kev lag luam. Nws lub luag haujlwm tau hais meej tshwj xeeb hauv kev lag luam cement, uas tuaj yeem ua rau muaj kev tsim khoom ntau dua thiab txo kev siv hluav taws xob.
