Los ntawm HRC mus rau HV: Yuav Ua Li Cas Hloov thiab Txhais Cov Nqi Hardness hauv Chromium Carbide Overlay Plates

Thaum nws los txog rau kev ntsuam xyuas kev ua haujlwm ntawm ib qhochromium carbide overlay hnav phaj, qhov nyuaj yog ib qho ntawm cov cim qhia tseem ceeb tshaj plaws. Txawm li cas los xij, thoob plaws ntiaj teb kev lag luam, ntau txoj kev sim thiab cov chav ntsuas feem ntau ua rau muaj kev tsis meej pem ntawm cov neeg yuav khoom, cov engineers, thiab cov thawj coj project. Kev nkag siab txog qhov sib txawv ntawm HRC (Rockwell hardness) thiab HV (Vickers hardness), thiab yuav ua li cas txhais cov nqi no, tuaj yeem cuam tshuam rau koj cov khoom xaiv, kev sib tham txog tus nqi, thiab kev cia siab rau kev ua tau zoo.

Vim li cas cov neeg siv khoom thiaj li mob siab txog kev hloov pauv hardness?

Cov lag luam thiab thaj chaw sib txawv nyiam cov chav sib txawv ntawm qhov nyuaj. Piv txwv li:

Cov neeg yuav khoom hauv Asmeskas thiab European feem ntau thov cov nqi Rockwell C (HRC).

Cov koom haum Esxias thiab cov koom haum txuj ci yuav nyiam cov ntaub ntawv Vickers (HV), tshwj xeeb tshaj yog rau kev ntsuam xyuas me me.

Ua tus neeg muab khoom thoob ntiaj teb ntawm cov phaj hnav tawv, Wodon feem ntau tau txais cov lus nug zoo li:

"Yog tias qhovCCO hnav phajyog ntsuas ntawm 60 HRC, qhov Vickers hardness sib xws yog dab tsi?

Kev teb qhov no xav tau ntau tshaj li lub tshuab xam zauv xwb - nws yuav tsum nkag siab txog qhov sib txawv ntawm cov ntsiab cai sim thiab cov qauv khoom siv.

Nkag Siab Txog HRC thiab HV: Kev Piav Qhia Txog Cov Txheej Txheem Kuaj

1. Rockwell C Hardness (HRC)

Ntsuas qhov tob ntawm qhov indentation los ntawm lub pob zeb diamond cone nyob rau hauv lub load tseem ceeb.

Ceev thiab siv tau rau kev ntsuam xyuas qhov nyuaj ntawm macroscopic, tshwj xeeb tshaj yog rau cov khoom hlau.

Feem ntau hauv kev sim cov kab ntau lawm ntawm cov phaj hnav.

2. Vickers Hardness (HV)

Siv lub pob zeb diamond pyramidal indenter thaum muaj cov khoom me me.

Ntsuas qhov ntev ntawm qhov indentation los ntawm kev tsom xam optical.

Zoo tagnrho rau kev tshuaj xyuas cov cheeb tsam me me, tshwj xeeb tshaj yog cov txheej hardfacing lossis cov chromium carbide ib tus zuj zus.

Txawm hais tias ob qho tib si siv tau, lawv ua haujlwm sib txawv: HRC qhia txog qhov nyuaj ntawm qhov chaw dav dav, thaum HV tuaj yeem muab kev nkag siab txog microhardness thiab carbide zoo.

HRC rau HV: Cov Kev Hloov Pauv Ib Txwm Muaj rau Chromium Carbide Overlay Wear Plates

Nov yog daim ntawv hloov pauv yooj yim raws li cov ntaub ntawv sim los ntawm cov phaj sib xyaw ua ke:

⚠ Ceeb Toom: Cov nqi no yog kwv yees xwb. Kev hloov pauv ib-rau-ib ncaj qha tsis yog qhov tseeb vim muaj qhov sib txawv ntawm cov txheej txheem sim thiab cov qauv khoom txheej.

Vim li cas peb thiaj tsis tuaj yeem hloov HRC mus rau HV raws nraim?

Muaj ntau yam tseem ceeb:

Cov Txheej Txheem Ntsuas Sib Txawv

HRC siv kev ntsuas qhov tob; HV vam khom rau ntawm cov kab pheeb ces kaum optical.

Cov duab ntawm lub qhov (indenter), cov hom khoom thauj, thiab thaj chaw kuaj sib txawv.

Cov Qauv Khoom Siv Tseem Ceeb

A bimetallic hnav phajmuaj cov khoom siv chromium carbide nyuaj uas muab tso rau hauv cov hlau tsis muaj zog.

Qhov nyuaj tuaj yeem sib txawv ntawm qhov chaw, qhov chaw hauv qab, thiab cov khoom siv hauv paus.

Cov Kev Hloov Pauv ntawm Chaw Tsim Khoom

Cov khoom sib xyaw ua ke sib txawv, cov txheej txheem vuam, thiab kev kho cua sov cuam tshuam rau cov txiaj ntsig ntawm kev sim.

Txawm tias nyob hauv tib pawg ntawm chromium carbide hnav phaj, HV nyeem tau tuaj yeem ntau ntawm 600 txog 1800, nyob ntawm qhov chaw koj sim.

Qhov nyuaj yog ib qho tseem ceeb heev, tab sis nws tsuas yog ib qho ntawm cov teeb meem thaum xaiv cov phaj hnav chromium carbide overlay zoo. Kev nkag siab txog qhov sib txawv ntawm HRC thiab HV, thiab yuav ua li cas txhais lawv kom raug, ua kom ntseeg tau tias muaj kev cia siab ua tau zoo dua thiab kev txiav txim siab zoo dua ntawm daim ntawv thov.

Yog tias koj tsis paub meej tias qhov kev qhia txog qhov nyuaj twg haum rau koj qhov xwm txheej ua haujlwm, tham nrog peb pab neeg - peb tuaj yeem muab cov ntaub ntawv kuaj xyuas kom ntxaws thiab cov lus qhia raws li daim ntawv thov uas tsim rau koj cov teeb meem hnav.
