Kev faib tawm ntawm chromium steel pob:
1, siab chromium steel pob yog ib qho tseem ceeb sib tsoo lub cev nyob rau hauv lub pob zeb, hu ua sib tsoo steel pob. Cov pob hlau yog lub ntiaj teb crushing kev lag luam tam sim no thiab txawm tias yav tom ntej ntawm *** loj hnav cov khoom siv tiv thaiv kev noj qab haus huv, hauv 2010 tsuas yog kev lag luam hauv teb chaws ntxhia uas tau noj txog 2 lab tons ntawm ntau yam khoom ntawm steel pob. , thiab kev lag luam cement hauv 2010 yuav tsum tau siv cov ntaub ntawv ntawm 300 txhiab tons. High chromium steel npas yog tsim los ntawm nruab nrab zaus rauv smelting, hlau pwm los yog xuab zeb pwm casting, yog li cov khoom siv hluav taws xob hauv tsev feem ntau hu ua high chromium alloy casting pob. Cov pob hlau nrog cov ntsiab lus chromium Ntau dua lossis sib npaug li 10.0 feem pua thiab cov ntsiab lus carbon ntawm 1.80 feem pua -3.20 feem pua yog tag nrho cov pob chromium siab. Cov qauv hauv tebchaws xav kom siab chromium pob hardness (HRC) yuav tsum siab tshaj 58 degrees. Yog hais tias lub hardness ncav cuag lub siab chromium pob, kho cua sov thiab quenching kev kho mob yuav tsum tau saws. Tam sim no, domestic thiab txawv teb chaws siab chromium pob roj quenching, cua quenching, dej tov thiab lwm yam quenching txoj kev, xws li cov nrhiav hardness (HRC) yog tsawg tshaj li 54 degrees hauv qab no lub siab chromium pob hardness los yog tsis tau quenched kiag li. High chromium steel pellets yog dav siv nyob rau hauv metallurgical mines, cement tsev cov ntaub ntawv, thermal hwj chim tiam, flue gas desulfurization, aerated ua vaj tse, sib nqus cov ntaub ntawv, tshuaj kev lag luam, thee dej slurry, pellet, slag, ultrafine hmoov, ya tshauv, calcium carbonate, quartz xuab zeb thiab lwm yam kev lag luam
2. Qhov Performance index ntawm nruab nrab chromium pob:
Chromium cov ntsiab lus ntawm 3.0 feem pua ~ 7%. , lub teb chaws tus qauv yuav tsum tau ntawm chromium pob hardness (HRC) yuav tsum muaj ntau tshaj 47, los yog kom ntseeg tau cov steel pob chromium pob yuav tsum tau siv nyob rau hauv kub kub tempering kev kho mob (kom ua tiav lub hom phiaj ntawm kev tshem tawm cov kev ntxhov siab), xws li Raws li steel pob nto tsaus daj qhia tias cov khoom tau raug kho nrog kub tempering, xws li steel pob nto yog xim hlau xim qhia tias cov khoom tseem tsis kub tempering kho.
3. Qhov Performance index ntawm tsawg chromium pob:
Chromium cov ntsiab lus ntawm 0.5 feem pua ~ 2.5 feem pua, cov ntsiab lus carbon ntawm 1.80 feem pua thiab 3.20 feem pua hu ua low chromium pob, lub teb chaws tus qauv yuav tsum tsis tshua muaj chromium pob hardness (HRC) yuav tsum ntau tshaj 45, los yog cuam tshuam tus nqi ak acuity 1.5 J / ㎝ 2, los xyuas kom meej qhov zoo ntawm steel pob uas tsis muaj chromium pob kuj yuav tsum tau siv high kub tempering kev kho mob (kom ua tiav lub hom phiaj ntawm kev tshem tawm kev nyuaj siab), xws li steel pob nto tsaus daj qhia tias cov khoom muaj tau kho nrog kub tempering, xws li steel pob nto yog xim hlau qhia tias cov khoom tseem tsis kub tempering kho.
