Thaum kuaj qhov hardness ntawm carbon steel puag ncig tuav nrog qis hardness, peb yuav tsum xaiv ib tug hardness tester tsim nyog los xyuas kom meej tias qhov kev ntsuam xyuas yog qhov tseeb thiab zoo. Peb tuaj yeem txiav txim siab siv HRB nplai ntawm Rockwell hardness tester.
HRB scale ntawm Rockwell hardness tester siv lub pob steel indenter nrog ib txoj kab uas hla ntawm 1.588mm thiab ib qho kev sib tw xeem quab yuam ntawm 100KG. Kev ntsuas ntau ntawm HRB nplai yog teem rau ntawm 20-100HRB, uas yog tsim rau hardness kuaj ntawm feem ntau carbon steel puag ncig bar cov ntaub ntawv nrog qis hardness.
1.Yog tias cov pa roj carbon steel puag ncig tau quenched thiab muaj qhov nyuaj siab txog HRC40 - HRC65, koj yuav tsum xaiv Rockwell hardness tester. Rockwell hardness tester yog ib qho yooj yim thiab ceev rau kev khiav lag luam, thiab tuaj yeem ncaj qha nyeem cov nqi hardness, uas yog tsim rau kev ntsuas cov ntaub ntawv hardness siab.
2.Rau qee cov pa roj carbon steel puag ncig uas tau kho nrog carburizing, nitriding, thiab lwm yam., lub hardness saum npoo yog siab thiab cov tub ntxhais hardness tsawg. Thaum nws yog ib qho tsim nyog los ntsuas qhov nyuaj ntawm qhov chaw, lub Vickers hardness tester lossis microhardness tester tuaj yeem xaiv. Lub indentation ntawm Vickers hardness test yog square, thiab tus nqi hardness yog xam los ntawm kev ntsuas lub diagonal ntev. Kev ntsuas qhov tseeb yog qhov siab thiab tuaj yeem cuam tshuam qhov kev hloov ntawm hardness ntawm cov khoom nto.
3.Ntxiv rau HRB nplai ntawm Rockwell hardness tester, Brinell hardness tester kuj tseem siv tau los ntsuas cov khoom siv qis-hardness carbon steel puag ncig bar. Thaum kuaj carbon steel puag ncig tuav, nws cov indenter yuav tawm ntawm thaj chaw loj ntawm indentation ntawm cov khoom siv, uas tuaj yeem ua tau ntau dua thiab ua tiav muaj kev cuam tshuam qhov nruab nrab hardness ntawm cov khoom. Thaum lub sijhawm ua haujlwm ntawm hardness tester, Brinell hardness tester tsis nrawm thiab yooj yim li Rockwell hardness tester. Brinell hardness tester yog HBW nplai, thiab cov indenters sib txawv sib phim lub zog ntsuas. Rau cov pa roj carbon steel puag ncig cov tuav uas feem ntau tsis tshua muaj zog, xws li cov hauv lub xeev annealed, qhov hardness feem ntau yog nyob ib ncig ntawm HB100 - HB200, thiab Brinell hardness tester tuaj yeem xaiv.
4.For carbon steel puag ncig tuav nrog txoj kab uas hla loj thiab cov duab tsis tu ncua, ntau yam hardness testers feem ntau siv tau. Txawm li cas los xij, yog tias txoj kab uas hla ntawm lub voj voog me me, xws li tsawg dua 10mm, Brinell hardness tester tuaj yeem cuam tshuam qhov ntsuas qhov tseeb vim qhov loj me me. Lub sijhawm no, Rockwell hardness tester lossis Vickers hardness tester tuaj yeem xaiv. Lawv qhov loj me me me thiab tuaj yeem ntsuas qhov nyuaj ntawm cov qauv me me.
5.Rau irregularly zoo li carbon steel puag ncig tuav uas nyuaj rau tso rau ntawm lub workbench ntawm ib tug pa hardness tester rau kev ntsuas, portable hardness tester, xws li ib tug Leeb hardness tester, yuav xaiv tau. Nws siv cov cuab yeej cuam tshuam los xa cov kev cuam tshuam lub cev mus rau qhov chaw ntawm cov khoom raug ntsuas, thiab suav cov nqi hardness raws li qhov ceev ntawm qhov cuam tshuam lub cev rov qab. Nws yog ib qho yooj yim rau kev khiav lag luam thiab tuaj yeem ua qhov ntsuas ntawm qhov chaw ntawm cov khoom sib txawv thiab qhov ntau thiab tsawg.
