LeeB Hardness Tester
Tam sim no, tus Leeb Hardness Tester tau siv dav hauv qhov kev sim ua kom tawv nqaij ntawm castings. Lub Hardness Hardness Tester Saws txoj ntsiab cai ntawm Hardness Hardness Testing thiab siv Computerstures thiab hluav taws xob tester. Nws yog qhov yooj yim thiab yooj yim siv, kev nyeem ntawv yog ntau dua kev paub, thiab cov txiaj ntsig tau yooj yim tuaj yeem hloov tau yooj yim rau hauv Brinell hardness tseem ceeb, yog li nws yog dav tau txais tos.
Ntau lub voos xwm txheej yog qhov nruab nrab-rau-loj ua haujlwm, qee qhov hnyav peb tons, thiab tsis tuaj yeem kuaj ntawm lub rooj ntev zaum saum toj kawg nkaus. Cov kev ntsuas nyuaj ntawm cov chaw casumnum feem ntau yog siv cais tawm cov pas nrig lossis kuaj cov pob tw txuas rau castings. Txawm li cas los xij, tsis ntsuas bar tsis yog qhov kev ntsuas thaiv tuaj yeem hloov kho qhov ua haujlwm. Txawm hais tias nws yog tib qho hluav taws xob ntawm Molten hlau, cov txheej txheem casting thiab kev kho cua sov yog qhov zoo ib yam. Vim tias qhov sib txawv loj loj loj, tus nqi cua sov, tshwj xeeb yog tus nqi txias, yuav txawv. Nws yog qhov nyuaj kom ua rau ob tus muaj raws nraim tib lub hardness. Vim li no, ntau tus neeg siv khoom saib xyuas ntau ntxiv txog thiab ntseeg hauv lub hardness ntawm wardriece nws tus kheej. Qhov no yuav tsum muaj qhov ntsuas preable tawv tawv tiv thaiv kom sim lub hardness ntawm castings. Lub Heateb Hardness Tes ntxias daws cov teeb meem no, tab sis nws yog ib qho tsim nyog los them sai sai rau saum npoo ua haujlwm ntawm kev siv LeeB Hardness Tester. Lub Hardness Hardness Tester tau tseev kom muaj rau qhov chaw ntawm qhov chaw ua haujlwm.
Brinell Hardness Tester
Brinell hardness tester yuav tsum siv rau kev sim ua kom tawv ntawm cov khoom siv. Rau grey hlau castings nrog cov nplej coarse, qhov kev sim mob ntawm 3000kg quab yuam thiab 10mm pob yuav tsum tau siv ntau li ntau tau. Thaum lub teeb loj me me, rockwell hardness tester kuj tseem siv tau.
HLAU CASTINGS feem ntau muaj cov qauv tsis ncaj, thiab muaj ntau cov pa roj carbon, thiab lwm yam tsis zoo tshaj li cov hlau, thiab lub hardness dua li cov hlau, thiab lub zog ua kom sib txawv hauv cov chaw me me lossis cov ntsiab lus sib txawv. Tus neeg soj ntsuam ntawm Brinell Hardness Pester muaj qhov loj dua thiab muaj peev xwm ntsuas qhov nruab nrab ntawm cov khoom tawv nyob rau qee qhov ntau. Yog li no, Brinell Hardness Tester muaj qhov ntsuas qhov ntev dua thiab kev rho tawm me me ntawm kev ua kom muaj txiaj ntsig. Tus nqi ntsuas tawv tawv muaj nuj nqis yog tus sawv cev ntau dua ntawm qhov kev nyuaj ntawm lub workpiece. Yog li ntawd, Brinell Hardness Tester yog dav siv nyob rau hauv lub foundry kev lag luam.
Rockwell Hardness
Rockwell Hardness Cov tub sim siab tseem siv rau kev sim ua kom lub hardness ntawm cam khwb cia hlau. Rau kev ua haujlwm nrog thaj chaw zoo, yog tias tsis muaj qhov chaw txaus rau Brinell Hardness Test, Rockwell Hardness Xeem tseem tuaj yeem nqa tawm. Rau cov hlawsitic Mallable cam khwb cia hlau, chilled cam khwb cia hlau thiab hlau kis, hrc lossis hrc nplai yuav siv tau. Yog tias cov khoom siv tsis yog tusyees, ob peb kev nyeem ntawv yuav tsum ntsuas thiab tus nqi nruab nrab yuav tsum tau coj.
Ntug dej Hardness
Nyob rau hauv tus kheej cov xwm txheej, rau qee cov kab hlau nrog cov qauv loj, nws tsis raug tso cai txiav cov qauv, thiab nws tsis raug tso cam cam khwb cia kev sib tw rau kev sim tshuaj ntxiv rau kev sim hardness. Nyob rau lub sijhawm no, kev sim hardness yuav ntsib kev nyuaj. Rau qhov no, cov qauv sib koom ua ke yog los sim lub hardness nrog lub pob zeb ntawm ntug dej hardness ntawm qhov chaw du tom qab ua tiav. Piv txwv li, hauv cov yob txheem dav siv dav hauv kev lag luam metallurgical, nws tau muab cov khoom siv ntawm cov neeg ntsuas dej hardness yuav tsum tau siv los ntsuas lub hardness.
