Yuav ua li cas xaiv cov testner harder rau kev sim tubular mus kuaj?

1) Tuaj yeem Rockwell Hardness Tester tau siv los sim lub hardness ntawm cov steel yeeb nkab phab ntsa?

Cov ntaub ntawv xeem yog Sah-213m T22 yeeb nkab nrog cov taub txheej loj ntawm 16 hli thiab ib phab ntsa tuab ntawm 1.65mm. Cov kev ntsuas kev ntsuas tau ntawm lub pob zeb ua pob zeb yog li hauv qab no: Tom qab tshem tawm cov qauv siv xim rau ntawm lub pob zeb.) Tom qab kuaj, nws tuaj yeem pom tau tias lub phab ntsa yeeb nkab muaj qhov tsis tshua muaj kev ntsuas muaj nqis yog qis dhau, ua rau qhov kev ntsuas tsis raug.

Raws li GB / T 23018 «Metallic cov ntaub ntawv Rockwell Hardness Tes Ntsuas Ntu 1: Lub Rockwell Hardness yog 80hrbw thiab cov qauv tuab npaum li cas yog 1.5mm. Lub thickness ntawm qauv No. 1 yog 1.65mm, cov tuab ntawm Decarburized Txheej yog 1.4 ~ 1.45mm, uas yog ze li ntawm cov qauv uas tau teev nyob hauv GB / T 230.1-2018. Thaum lub sijhawm ntsuas, vim tias tsis muaj kev txhawb nqa nyob rau hauv qhov chaw ntawm cov qauv, nws yuav tsis pom los ntawm lub qhov muag liab), yog li tiag tiag rockwell hardness nqi tsawg.

2) Yuav ua li cas xaiv Sight Hardness Tester rau Hlau Kav:

Tom qab ntau qhov kev ntsuam xyuas ntawm lub npoo hardness ntawm cov kav hlau steel, peb lub tuam txhab tau tuaj rau cov lus xaus hauv qab no:

1. Thaum ua lub ntsej muag sib luag hauv rockwell hardness ntsuas lossis rockwell hardness ntsuas nyob rau saum npoo ntawm lub raj txheej hlau nyias nyias yuav ua rau muaj cov hnoos qeev thiab ua rau cov tshuaj ntsuam tsawg;

2. Yog tias kev txhawb nqa cylindrical yog ntxiv rau hauv nruab nrab ntawm cov yeeb nkab nyias-walled yuav ua rau muaj kev sib tw ntawm cov yeeb nkab ntawm cov hlau sab nraud thiab cov yeeb nkab sib txuas thiab cov yeeb nkab cylindrical.

3. Txoj kev hloov pauv cov kev ntsuas ntsuas kom tawv rau pob zeb hardness tom qab inlaying thiab polishing cov yeeb nkab txheem cov qauv yog qhov tseeb.

4. Tom qab tshem tawm cov nplai Oxide thiab Decarburnization txheej ntawm saum npoo hlau thiab tshuab raj ntawm rockwell hardness, uas yog qhov tseeb.
