X60 Kab yeeb nkab, Mechanical Properties Of
X60 Kab Yeeb Nkab, Kev kho cua sov saum npoo yog muab faib ua ob pawg, ib qho yog kev kho cua sov, ib qho yog deg quenching thiab tempering tshav kub kho, txoj kev sim hardness yog raws li nram no:
[1] Kev kho cua sov ntawm X60 pipeline
-- Kev kho cua sov yog ua rau saum npoo ntawm X60 pipeline tube infiltrate ib los yog ntau yam tshuaj atoms, thiaj li hloov cov tshuaj muaj pes tsawg leeg, qauv thiab cov khoom ntawm X60 pipeline tube nto.Tom qab quenching thiab tsis kub tempering, nto ntawm X60 pipeline yeeb nkab muaj siab hardness, hnav tsis kam thiab tiv taus qaug zog, thiab cov tub ntxhais ntawm X60 pipeline yeeb nkab muaj zog thiab toughness.
- Lub ntsiab kev tsis sib xws ntawm kev kho cua sov tshuaj X60 pipeline yog qhov tob ntawm txheej hardened thiab deg hardness.Qhov tob ntawm hardened txheej yuav tsum tau kuaj los ntawm vickers hardness tester.Ntsuas qhov kev ncua deb ntawm X60 yeeb nkab nto mus rau qhov chaw uas hardness poob mus rau 50HRC.Qhov no yog qhov ua tau zoo ntawm kev kho cua sov ntawm X60 pipeline tube nto hardness kuaj thiab nto hardening tshav kub kho qhov hardness ntawm X60 pipeline raj kuaj xyuas, tuaj yeem siv vickers hardness tester, nto rockwell hardness tester lossis rockwell hardness tester los kuaj, tsuas yog thickness ntawm nitriding tuab nyias, feem ntau tsis ntau tshaj 0.7 hli, ces siv tsis tau cov rockwell hardness tester, Microhardness tester yuav siv tau.
[2] X60 pipeline nto quenching thiab tempering kub kho
--Nto quenching thiab tempering tshav kub kho feem ntau yog ua los ntawm induction cua sov los yog nplaim hluav taws kub.Lub ntsiab technical parameters yog deg hardness, lub zos hardness thiab zoo hardening txheej tob.Vickers hardness tester tuaj yeem siv rau kev sim hardness, rockwell lossis nto Rockwell hardness tester.Kev xaiv ntawm kev xeem quab yuam ( nplai) muaj feem xyuam rau qhov tob ntawm cov txheej txheem hardening zoo thiab qhov tawv tawv ntawm X60 pipeline.Muaj peb hom hardness meters koom nrog.
Vickers hardness tester yog ib qho tseem ceeb los ntsuas qhov tawv tawv ntawm cov khoom siv hluav taws xob kho X60 kav dej.Nws tuaj yeem siv 0.5 ~ 100kg xeem quab yuam los kuaj cov txheej txheej tawv tawv li nyias li 0.05 hli.Nws qhov tseeb yog qhov siab tshaj plaws, thiab nws tuaj yeem paub qhov txawv me ntsis ntawm qhov tawv tawv ntawm cov khoom siv hluav taws xob kho X60 kav dej.Tsis tas li ntawd, qhov tob ntawm cov txheej txheem hardening zoo kuj ntsuas los ntawm vickers hardness tester, yog li nws yog ib qho tsim nyog yuav tsum tau nruab Vickers hardness tester rau cov units uas nqa tawm kev kho cua sov los yog siv ntau qhov chaw kho cua sov ua haujlwm.
-- Surface Rockwell hardness tester kuj yog qhov tsim nyog rau kev ntsuam xyuas qhov nyuaj ntawm qhov chaw hardened X60 pipeline yeeb nkab.Muaj peb teev rau saum npoo Rockwell hardness tester xaiv los ntawm.Muaj peev xwm kuaj tau ntau yam ntawm cov tawv tawv X60 kab nrog kev ua haujlwm zoo hardening qhov tob tshaj 0.1 hli.Txawm hais tias qhov tseeb ntawm qhov chaw Rockwell hardness tester tsis yog siab npaum li vickers hardness tester, nws tuaj yeem ua tau raws li qhov yuav tsum tau ua raws li txoj hauv kev rau kev tswj kom zoo thiab kev soj ntsuam xyuas hauv cov nroj tsuag kho cua sov.Ntxiv mus, nws kuj muaj cov yam ntxwv ntawm kev ua haujlwm yooj yim, siv yooj yim, tsis tshua muaj nqi, ntsuas nrawm, thiab tuaj yeem nyeem ncaj qha cov nqi hardness, thiab lwm yam Surface Rockwell hardness tester tuaj yeem siv rau batch ntawm kev kho cua sov saum npoo X60 pipeline yeeb nkab sai thiab tsis- kev kuaj puas tsuaj.Qhov no yog qhov tseem ceeb heev rau X60 pipeline processing thiab machinery manufacturing plant.
- Rockwell hardness tester kuj tseem siv tau thaum txheej txheej tawv tawv yog tuab.Thaum lub thickness ntawm hardened txheej ntawm kev kho cua sov yog 0.4 ~ 0.8 hli, HRA nplai yuav siv tau, thaum lub thickness ntawm hardened txheej yog ntau tshaj 0.8 hli, HRC scale yuav siv tau.
- Vickers, Rockwell thiab Surface Rockwell hardness qhov tseem ceeb tuaj yeem hloov tau yooj yim rau hauv tus qauv, kos duab lossis cov neeg siv yuav tsum muaj qhov tseem ceeb hardness.Cov lus hloov pauv tau raug muab rau hauv cov qauv thoob ntiaj teb ISO, Asmeskas tus qauv ASTM thiab Suav tus qauv GB / T.
[3] Kev kho cua sov hauv zos
- Yog hais tias lub zos hardness ntawm qhov chaw yuav tsum siab, lub zos quenching tshav kub kev kho mob yuav nqa tawm los ntawm induction cua sov thiab lwm yam kev.Xws li X60 pipeline kav feem ntau yuav tsum tau kos lub qhov chaw ntawm lub zos quenching tshav kub kev kho mob thiab lub zos hardness nqi ntawm daim duab.Kev ntsuas hardness ntawm X60 yeeb nkab yuav tsum tau ua nyob rau hauv qhov chaw xaiv.Cov cuab yeej ntsuas hardness tuaj yeem siv Rockwell hardness tester, kuaj HRC hardness tus nqi, xws li kev kho cua sov hardening txheej yog ntiav, siv tau nto Rockwell hardness tester, kuaj HRN hardness nqi.
