Yuav ua li cas xaiv cov testial harder rau kev sim tubular cov qauv

1) Muaj peev xwm rockwell hardness tester siv tau los sim lub hardness ntawm steel yeeb nkab phab ntsa?

Cov ntaub ntawv xeem yog Sa 213m T22 yeeb nkab nrog ib txoj kab uas hla ntawm 16 hli thiab ib phab ntsa tuab ntawm 1.65mm. Cov kev ntsuas ntsuas ntawm Rockwell Hardness Testness cov khoom ua haujlwm nrog lub ntsej muag ua haujlwm nrog lub rooj ua haujlwm sab nraud, siv lub pob zeb ua haujlwm sab nraud, siv lub pob zeb ua haujlwm sab nraud,

Tom qab kuaj, nws tuaj yeem pom tau tias cov yeeb nkab steel ntawm phab ntsa muaj qhov tshwm sim me ntsis, thiab qhov tshwm sim yog: tus nqi qis ntsuas ntawm Rockwell Hardness ua rau kev sim tsis raug.

Raws li GB / T 230.1-2018 «Rockwell Hardness Kuaj rau Metallic Cov Khoom Siv Tshooj 1: Lub Rockwell Hardness yog 80hrbw thiab qhov tsawg kawg nkaus ntawm cov quav me yog 1.5mm. Lub thickness ntawm cov qauv no.1 yog 1.65mm, cov tuab ntawm Decarburized Txheej yog 1.4 ~ 1.45mm, uas yog ze rau thickness ntawm cov qauv uas tau teev nyob rau hauv GB / T 230.1-2018.

Thaum lub sijhawm kuaj, vim yog lub chaw ua haujlwm tsis txaus siab, nws yuav pom tsis meej (tej zaum yuav pom tsis tau rau lub ntsej muag) deformation, yog li lub rockwell hardness ntsuas tus nqi yog theej tsawg.

2) Yuav ua li cas xaiv cov sab nraudUa las voosHardness Tester rau Kev Ntsuas Cov Kav Hlau:

Peb lub tuam txhab tau sim ua qhov nyuaj ntawm cov yeeb nkab steel thiab tau mus txog cov lus xaus hauv qab no:

Superficial rockwell hardness ntsuas los yog rockwell hardness ntsuas nyob rau saum npoo ntawm nyias-walled-walled steel yeeb nkab. Cov hluav taws xob hluav taws xob tsis txaus yuav ua rau muaj cov hnoos qeev thiab ua rau muaj kev ntsuas tsawg;

Yog tias muab cov pob cylindrical nyob hauv nruab nrab ntawm cov yeeb nkab hlau, vim tias qhov sib txawv ntawm cov yeeb nkab ntawm cov yeeb nkab steel, thiab yuav ua rau cov khoom lag luam sib txawv

Hloov ua lwm yam kev sim ua rau Rockwell Hardness Kuaj tom qab polling cov yeeb nkab steel, yuav tau txais ib qho hluav taws xob muaj tseeb.

2. Tom qab tshem cov roj oxide thiab decarburization nyob rau saum npoo ntawm cov yeeb nkab steel thiab tus nqi sib zog, tus nqi sib zog, tus nqi sib zog, tus nqi sib zog ua ke ntawm cov pob zeb tawv nqaij tawv
