Qhov nyuaj ntawm cov yeeb nkab hlau yog hais txog lub peev xwm ntawm cov khoom siv los tiv taus kev hloov pauv hauv qab lub zog sab nraud. Qhov nyuaj yog ib qho ntawm cov cim qhia tseem ceeb ntawm kev ua tau zoo ntawm cov khoom siv.
Hauv kev tsim thiab siv cov kav hlau, kev txiav txim siab ntawm lawv qhov nyuaj yog qhov tseem ceeb heev. Qhov nyuaj ntawm cov kav hlau tuaj yeem ntsuas los ntawm ntau yam kev sim nyuaj xws li Rockwell, Brinell, thiab Vickers tsim los ntawm Laizhou Laihua Testing Instrument Factory, uas tuaj yeem hloov kho raws li qhov xav tau. Cov txheej txheem ntsuas tseem ceeb suav nrog cov hauv qab no:
1. Txoj kev kuaj mob Rockwell hardness
Kev ntsuas Rockwell hardness yog txoj kev siv dav tshaj plaws tam sim no, ntawm cov HRC yog qhov thib ob tom qab Brinell hardness HB hauv tus qauv yeeb nkab hlau. Nws ntsuas qhov tob ntawm qhov indentation thiab tuaj yeem siv los ntsuas cov khoom siv hlau los ntawm mos heev mus rau tawv heev. Nws yooj yim dua li txoj kev ntsuas Brinell.
2. Txoj kev kuaj Brinell hardness
Txoj kev kuaj xyuas Brinell hardness kuj siv dav hauv kev lag luam. Nws siv dav hauv cov qauv yeeb nkab hlau seamless. Qhov nyuaj ntawm cov khoom siv feem ntau qhia los ntawm txoj kab uas hla ntawm qhov indentation. Nws yooj yim to taub thiab yooj yim siv, tab sis nws tsis siv tau rau cov yeeb nkab hlau nyuaj dua lossis nyias dua.
3. Txoj kev kuaj xyuas qhov nyuaj ntawm Vickers
Qhov kev xeem Vickers hardness kuj siv dav. Nws muaj cov txiaj ntsig tseem ceeb ntawm Brinell thiab Rockwell kev xeem, tab sis kov yeej lawv cov kev tsis zoo yooj yim. Nws yog qhov tsim nyog rau kev xeem hardness ntawm ntau yam khoom siv, tab sis tsis haum rau cov qauv nrog cov kab me me. Nws tsis yooj yim li txoj kev xeem Rockwell thiab tsis tshua siv hauv cov qauv yeeb nkab hlau.
