Kev Ntsuas Qhov Hardness Twg Zoo Tshaj Plaws Rau Cov Phaj Hnav: Brinell, Rockwell, lossis Vickers?

Hauv cov chaw ua haujlwm abrasive uas cov phaj hnav tau siv - xws licov qhov av khawb av, cov thoob hlau, lossis cov ntaub pua plag cement - qhov nyuaj tsis yog ib tus lej xwb.

Rau ib qhochromium carbide overlay hnav phajlos yog ib lub phaj bimetallic uas tiv taus kev hnav, nws yog ib qho kev ntsuas kev ua tau zoo tseem ceeb uas kwv yees qhov ruaj khov, xyuas kom meej tias kev tsim khoom zoo, thiab ua kom cov neeg siv khoom kawg ntseeg siab.

Tab sis ntawm cov kev ntsuam xyuas qhov nyuaj uas feem ntau siv - Brinell (HB), Rockwell (HRC), thiab Vickers (HV) - qhov twg zoo tshaj plaws rau cov ntaub ntawv sib xyaw niaj hnub uas tiv taus kev hnav?

Vim Li Cas Kev Ntsuas Qhov Nyuaj Tseem Ceeb Hauv Chromium Carbide Wear Plates

Kev hnav tsis kam = Hardness:

Hauv kev siv abrasive lossis kev cuam tshuam siab, qhov nyuaj ntawm qhov chaw ntawm chromium carbide hnav-resistant phaj ncaj qha cuam tshuam nws lub neej.

Kev Tswj Xyuas Kev Tsim Khoom: Kev kuaj xyuas qhov nyuaj tsis tu ncua ua kom ntseeg tau tias cov txheej txheem vuam overlay tsim cov txiaj ntsig zoo sib xws.

Kev Ntseeg Siab ntawm Cov Neeg Siv Khoom: Cov nqi tawv uas tau sau tseg pab cov engineers thiab cov pab pawg yuav khoom txheeb xyuas qhov ua tau zoo ntawm cov khoom siv ua ntej.

Cov qauv ntawm Bimetallic Wear Plate: Vim li cas kev sim thiaj li nyuaj

A bimetallic hnav phajfeem ntau muaj xws li:

Lub hauv paus hlau me me (rau kev vuam thiab kev txhawb nqa cov qauv)

Txheej txheej tawv tawv (feem ntau yog chromium carbide)

Cov qauv ob txheej no ua rau kev sim nyuaj:

Yog tias daim txheej nyias dhau, kev ntsuam xyuas yuav ntsuas cov hlau hauv paus yam tsis tau xav txog.

Yog tias qhov chaw tsis sib npaug lossis muaj cov slag, cov txiaj ntsig yuav txawv.

Cov Txheej Txheem Ntsuas Qhov Nyuaj: Qhov Zoo & Qhov Tsis Zoo

3.1 Brinell Hardness (HB)

Nws ua haujlwm li cas: Siv lub pob hlau/tungsten los ntxig rau saum npoo thaum muaj kev thauj khoom hnyav.

Siv cov ntaub ntawv: Zoo dua rau cov khoom siv mos xws li lub hauv paus phaj.

Kev Txwv: Ntxaib dhau rau cov txheej nyias nyias. Kev ntxig rau hauv qhov yuav ua rau cov nyeem ntawv los ntawm ob txheej sib xyaw.

Kev Txiav Txim: ✅ Zoo rau cov hlau puag / ❌ Tsis zoo rau cov khoom siv tawv

3.2 Rockwell Hardness (HRC)

Nws ua haujlwm li cas: Lub khob hlau lossis pob zeb diamond siv zog; qhov tob ntsuas tau hauv hluav taws xob.

Kev siv: Feem ntau siv rau hauv cov chaw ua haujlwm thaum lub sijhawm tsim khoom.

Kev Txwv: Qhov tuab ntawm cov overlay thiab qhov tsis sib xws ntawm cov qauv microstructure tuaj yeem ua rau cov txiaj ntsig tsis sib xws.

Kev Txiav Txim: ✅ Qhov tseeb nruab nrab / ⚠ Yuav tsum tau ua tib zoo calibration

3.3 Vickers Hardness (HV)

Nws ua haujlwm li cas: Lub pob zeb diamond pyramid indenter nias rau ntawm qhov chaw, thiab qhov indentation raug ntsuas los ntawm optically.

Siv cov ntaub ntawv: Zoo heev rau cov txheej nyias nyias thiab kev ntsuas qhov tseeb hauv chaw kuaj mob.

Kev Txwv: Yuav tsum tau teeb tsa kws tshaj lij, siv sijhawm ntau dua.

Kev Txiav Txim: ✅✅ Kev xaiv zoo tshaj plaws rauchromium carbide overlay hnav phaj

Lus Qhia Luv: Koj Yuav Tsum Siv Qhov Kev Xeem Twg?

Rau kev ntsuam xyuas cov phaj chromium carbide lossis cov txheej txheem bimetallic, Vickers muab cov txiaj ntsig tseeb tshaj plaws thiab tshwj xeeb tshaj yog thaum cov tuab ntawm cov txheej txheem qis dua 6 hli.

Cov Yam Uas Cuam Tshuam Rau Qhov Tseeb Ntawm Kev Ntsuas

Yuav kom tau txais cov ntawv nyeem qhov nyuaj thiab ruaj khov ntawm cov khoom siv chromium carbide hnav-resistant phaj, xav txog cov hauv qab no:

Thickness Overlay: Nyias dhau = kev cuam tshuam ntawm cov hlau puag

Qhov Xwm Txheej Ntawm Qhov Chaw: Cov hlaws dai vuam, cov slag, lossis cov cim sib tsoo yuav cuam tshuam rau kev nyeem ntawv

Thaj Chaw Dilution: Cov cheeb tsam sib xyaw ua ke ntawm cov khoom sib tshooj thiab lub hauv paus tuaj yeem ua rau qhov nyuaj ntawm thaj chaw
