Hardness Ntsuas Cov Qauv rau Zoo - HOM mult - lub hom phiaj rauv

Nws muaj peb lub ntsiab kev sim ua rau lub pit - hom furnaces: vickers, rockwell, thiab rockwell salfical. Nyob ntawm cov txheej txheem kev kho cua sov, cov qauv kev sim ua kom muaj zog rau kev kho cua sov thiab ntsuas cua sov kuj sib txawv.
Qhov tseem ceeb ntawm cov kab mob rau tshuaj thaum kub kub -}} nrhiav cov haujlwm ua haujlwm tob thiab tawv tawv. Lub hardened txheej tob tseem ntsuas tau siv vickers lub ntsuas kev ua haujlwm nyuaj. Qhov kev ua tau zoo ua tau yog ntsuas los ntawm cov workpiece nto rau qhov uas lub hardness dauv rau 50 hrc.
Tshuaj lom neeg kho cua sov cuam tshuam nrog cov atoms ntawm ib lossis ntau dua kev hloov pauv ntawm cov chaw ua haujlwm, qauv, thiab khoom. Tom qab quenching thiab tsawg {{- kub txias, hnav tsis kam, thiab hu rau kev qaug zog siab, thaum tus tub tseem ceeb.

Kuaj cov npoo tawv ntawm cov cua sov -}}} Cov neeg ua haujlwm zoo ib yam li kev sim lub hardness ntawm saum npoo- Cov workpieces. Ob qho tib si tuaj yeem sim siv Vickers Hardness Tester, lub Rockwell nto hardness tester, lossis pob zeb saum npoo av tawv tawv tester. Txawm li cas los xij, cov tuab tuab ntawm cov txheej nitrived yog qhov yooj yim nyias, feem ntau tsis muaj ntau dua 0.7mm, yog li ntawd lub rockwell nto sib yeem xov xwm tsis tuaj yeem siv.

Yog tias ib feem yuav tsum muaj kev nyuaj siab hauv zos, hauv zos quenching cua sov tuaj yeem ua tau siv cov hau kev xws li cov cua sov. Rau cov ntu no, qhov chaw nyob thiab lub zog hardness muaj nuj nqis ntawm lub zos quenching cua sov yuav tsum tau cim rau ntawm daim duab. Kev kuaj Hardness yuav tsum tau ua nyob rau hauv thaj chaw xaiv tseg. Lub pob zeb rockwell Hardness tuaj yeem siv los ntsuas HRC Hardness. Yog tias cov cua sov -} nrhiav cov txheej hardened yog ntiav, lub rockwell saum npoo hardness teser tuaj yeem siv los ntsuas kev ua haujlwm HRN hardness.

Nto Quenching thiab tempering cua sov kev kho mob nyob rau hauv lub qhov cub rauv feem ntau yog ua siv cov khoom cua sov lossis nplaim hluav taws xob. Qhov tseem ceeb technical yog nto hardness, hardness hauv zos, thiab ua tau zoo txheej qhov tob. Kev kuaj Hardness tuaj yeem ua tau siv Vickers Hardness Tester, ib lub rockwell nto hardness tester, lossis lub rockwell nto hardness teser. Kev xaiv ntawm kev sim quab yuam (nplai) muaj feem cuam tshuam nrog cov khoom siv tawv tawv ua haujlwm tob thiab workpiece nto hardness. Peb hom kev ntaus pob ntawm cov tawv tawv muaj kev koom tes nrog. Lub Vickers Hardness Tester yog ib qho cuab yeej tseem ceeb rau kev sim cov nplaim hluav taws xob ntawm tshav kub- kho workpieces. Nws tuaj yeem ua haujlwm nrog kev sim siab ntawm 0.5 txog 100 kg thiab tuaj yeem sim cov npoo hardened li nyias li 0.05 hli tuab. Nws qhov tseeb siab tau tso cai rau kev pom zoo rau qhov sib txawv me tshaj plaws hauv cov workpiece nto hardness. Tsis tas li ntawd, cov khoom siv tawv tawv tawv qhov tob yuav tsum tau txiav txim siab siv Vickers Tester Tester. Yog li ntawd, nws yog qhov tseem ceeb rau cov koomhaum uas ua kom sov kev kho lossis siv ntau ntawm cov cua sov {}}} kev kho workpieces kom muaj ib qho.

Cov khoom siv hluav taws xob ntawm lub pob zeb saum taub hau Muaj nyob rau hauv peb teev, nws tuaj yeem sim ntau yam - hate hardening workpieces nrog zoo ua haujlwm tob tshaj 0.1 mm. Txawm hais tias tsis yog qhov tseeb li Vickers Hardness Teser, lub pob zeb loj heev ua tau raws li kev tswj hwm zoo thiab kev tshuaj xyuas zoo hauv cov nroj tsuag cua sov. Tsis tas li ntawd, nws yog qhov yooj yim rau kev ua haujlwm, siv tau yooj yim, pheej yig, thiab muaj kev ntsuas nrawm nrawm thiab ncaj qha nyeem. Using a superficial Rockwell hardness tester allows for rapid, non-destructive, piece-by-piece testing of batches of surface-heat-treated workpieces. Qhov no yog qhov tseem ceeb rau kev siv hlau ua haujlwm thiab tshuab tsim khoom siv. Thaum tshav kub kub -} nrhiav cov txheej hardened rau saum npoo ntawm ib lub qhov cub hluav taws xob yog tuab, lub pob zeb hluav taws xob ua tau kuj tseem siv tau. Thaum lub hardened txheej thickness yog nruab nrab ntawm 0.4 thiab 0.8 mm, HRA nplai yuav siv tau; Thaum cov tawv tawv tawv tuab tshaj 0.8 hli, lub HRC nplai tuaj yeem siv tau.

Vickers, Rockwell, thiab rockwell skascial hardness tseem ceeb tuaj yeem hloov kho yooj yim los ntawm cov qauv, kos duab, lossis cov neeg siv. Kev hloov dua siab Ntxhuav tau muab nyob rau hauv International ISO, Asmeskas Astm, thiab Suav GB / T qauv.
