Lub hardness ntawmKev cai crusher hnav qhov chawYog qhov tseem ceeb hauv kev tshuaj xyuas lawv cov khoom zoo, ua rau kev sim ua kom tawv ntawm cov hnav-resistant castings uas tseem ceeb. Raws li tus kws tshaj lij manganese steel casting qhov chaw tsum, peb yuav qhia ntau hom kev sim hardness feem ntau.
Brinell Hardness Ntsuas
Lub Brinell Hardness Tester cov cim cov khoom siv rau kev nyuaj siab los ntawm kev ntsuas cov qib uas cov indenter nkag rau covKev cai crusher hnav qhov chawQauv. Hom qauv no, tau npaj los ntawm Swedish engeyer johan Lub yim hli ntuj Brinell hauv xyoo 1900, yog ib qho ntawm cov txheej txheem kev sim ua kom zoo sib xws hauv cov chaw muaj cov chaw. Txawm hais tias qhov loj me me ntawm cov indentation yuav cuam tshuam cov qauv siv, tus nqi brinell tuaj yeem hloov ncaj qha hloov dua tshiab rau kev sim cov khoom Crusher hnav.
Rockwell Hardness Ntsuas
Pom zoo los ntawm high manganese steel casting qhov chaw muab khoom, lub pob zeb pob zeb hardness txiav txim siab hardness los ntawm kev ntsuas qhov tob ntawm qhov ntsuas hluav taws xob hauv cov khoom siv sib txawv. Hom no yog qhov tsim nyog tshwj xeeb rau kev kuaj ntawm lub xaib ntawmKev cai crusher hnav qhov chaw, raws li nws yog ib qho yooj yim rau kev khiav lag luam thiab cov khoom siv yog portable. Cov chaw nqis looj cov chaw ua haujlwm feem ntau siv HRC nplai kom ntsuas qhov kev ua tau nyuaj ntawm kev ua tau zoo ntawm manganese steel casings.
Vickers Hardness Test
Lub vickers kev sim siab, tsim los ntawm vickers Ltd., yog ib qho kev xaiv rau kev sim lub hardness ntawm cov khoom siv kev cai hauv cov chaw teeb tsa cov chaw. Hom qauv no haum rau txhua cov ntaub ntawv hlau, suav nrog ntau qib ntawm cov hlau siab steele steel casings. Raws li tus kws tshaj lij manganese steel casting qhov chaw tsum khoom, peb pom zoo kom siv HV hardness nplai kom ntsuas tau qhov ua tau zoo ntawmKev cai crusher hnav qhov chaw.
Los ntawm kev siv peb txoj kev sim hardness, crusher hnav qhov chaw muaj txiaj ntsig yuav nkag siab txog kev tswj hwm cov khoom zoo ntawmKev cai crusher hnav qhov chaw, kom ntseeg tau tias cov khoom lag luam raws cov qauv qauv zoo.
