40Cr, 40 chromium Rockwell hardness xeem txoj kev

Tom qab quenching thiab tempering, chromium muaj cov khoom siv zoo heev thiab hardenability zoo, uas ua rau nws feem ntau siv rau hauv kev tsim cov khoom siv muaj zog siab, bearings, iav, thiab camshafts. Cov khoom siv kho tshuab thiab kev kuaj hardness yog qhov tsim nyog heev rau quenched thiab tempered 40Cr.

Feem ntau, kev kuaj xyuas qhov nyuaj ntawm 40Cr siv txoj kev kuaj xyuas Rockwell hardness thiab txoj kev kuaj xyuas Brinell hardness rau kev kuaj xyuas. Vim tias Rockwell hardness tester siv tau sai thiab yooj yim, cov neeg siv khoom feem ntau nyiam nws. Rau cov khoom me me lossis cov khoom uas xav tau kev ntsuas siab dua, Vickers hardness tester kuj tseem siv tau.

Feem ntau, qhov Rockwell hardness ntawm 40Cr tom qab quenching thiab tempering feem ntau yuav tsum nyob nruab nrab ntawm HRC32-36, yog li nws muaj zog dua thiab tsis kam qaug zog.

Cov hauv qab no yog ntau cov Rockwell hardness testers uas siv ntau rau kev siv:

1. Lub tshuab ntsuas qhov hnyav ntxiv hluav taws xob digital Rockwell hardness tester: qhov tseeb, txhim khu kev qha, ruaj khov, thiab ua haujlwm tau zoo; lub vijtsam digital tuaj yeem nyeem ncaj qha Rockwell hardness tus nqi, cov qauv kho tshuab tau zoo, thiab lwm yam Rockwell nplai tuaj yeem phim tau. Nws siv cov thev naus laus zis hluav taws xob thauj khoom thiab tshem tawm tsis siv neeg kom tshem tawm cov yuam kev ntawm tib neeg. Lub kaw lus spindle siv cov qauv spindle tsis muaj kev sib txhuam los txhim kho qhov tseeb ntawm lub zog xeem thawj zaug.

2. Kov npo digital zaub Rockwell hardness tester: yim nti kov npo ua haujlwm, yooj yim thiab yooj yim rau kev khiav lag luam interface; hluav taws xob loading xeem zog, qis tsis ua haujlwm, kev xeem raug dua, tuaj yeem khaws cia 500 pawg ntawm cov ntaub ntawv, tua hluav taws xob yam tsis poob cov ntaub ntawv, ua raws li ISO, ASTM E18 thiab lwm yam qauv.

3. Lub tshuab ntsuas Rockwell hardness tag nrho: lub zog ntsuas hluav taws xob siv los txhim kho qhov tseeb ntawm lub zog, ib-nias kom ua tiav tag nrho cov txheej txheem ntsuas hardness, yooj yim thiab ua haujlwm tau zoo; lub platform xeem loj heev, tsim nyog dua rau kev kuaj xyuas qhov nyuaj ntawm cov haujlwm loj; nruab nrog lub joystick kom tsav lub cev muaj zog servo sai sai los kho qhov chaw xeem; cov ntaub ntawv tuaj yeem xa mus rau lub khoos phis tawj ntawm RS232, Bluetooth lossis USB.
