Cov yam ntxwv thiab kev siv ntawm Rockwell hardness tester

Kev ntsuam xyuas ntawm Rockwell hardness tester yog ib qho ntawm peb feem ntau siv txoj kev kuaj hardness.

Cov yam ntxwv tshwj xeeb yog raws li hauv qab no:

1) Rockwell hardness tester yog yooj yim rau kev khiav lag luam tshaj Brinell thiab Vickers hardness tester, tuaj yeem nyeem ncaj qha, nqa kev ua haujlwm siab.

2) Muab piv nrog Brinell hardness test, qhov indentation yog me dua ib qho ntawm Brinell hardness tester, yog li nws tsis muaj kev puas tsuaj rau saum npoo ntawm lub workpiece, uas yog tsim nyog rau kev tshawb nrhiav cov khoom tiav ntawm cov cuab yeej txiav, pwm, ntsuas cov cuab yeej, cov cuab yeej, thiab lwm yam.

3) Vim yog lub zog kuaj ua ntej ntawm Rockwell hardness tester, qhov cuam tshuam me ntsis ntawm qhov tsis sib xws ntawm tus nqi hardness tsawg dua li ntawm Brinell thiab Vickers, thiab nws yog qhov tsim nyog rau kev tsim khoom loj ntawm kev siv tshuab thiab metallurgical thermal processing thiab semi-tiav lossis tiav cov khoom soj ntsuam.

4) Nws muaj cov khoom me me ntawm Rockwell hardness tester nyob rau hauv qhov kev ntsuam xyuas, tuaj yeem siv los ntsuas qhov nyuaj ntawm qhov tob tob hardening txheej lossis txheej txheej txheej.
