Iav yog ib qho khoom siv sib kis tau zoo. Nws lub luag haujlwm tseem ceeb yog hloov qhov ceev thiab torque thaum xa lub zog thiab lub zog. Vim tias cov iav yuav tsum tiv taus cov khoom hnyav thiab kev sib txhuam, lawv yuav tsum muaj qhov nyuaj thiab lub zog txaus kom ntseeg tau tias lawv ua haujlwm li qub.
Kev ua haujlwm ntawm cov iav quenching thiab tempering
Iav quenching thiab tempering yog los txhim kho lub hardness thiab lub zog ntawm lub iav, yog li ua tiav cov haujlwm hauv qab no:
1. Nce hardness
Los ntawm cov iav tempering, lub hardness ntawm lub iav tuaj yeem nce ntxiv, thiab nws qhov hardness ntawm lub ntsej muag thiab qhov tob hardness tuaj yeem txhim kho, yog li txo qhov hnav thiab qaug zog puas ntawm cov hniav nto thiab ua kom muaj kev pab cuam lub neej ntawm cov iav.
2. Ua kom muaj zog
Lub zog ntawm lub iav hais txog nws lub peev xwm los tiv thaiv kev khoov thiab qaug zog loads. Iav tempering tuaj yeem txhim kho lub zog thiab qaug zog ntawm lub iav, tso cai rau nws tiv taus ntau dua.
3. Txhim kho hnav tsis kam thiab corrosion kuj
Lub iav tempered nto muaj kev hnav thiab corrosion ntau dua, uas tuaj yeem tiv thaiv lub iav nto los ntawm kev hnav, corroded thiab oxidized, yog li txuas nws lub neej kev pab cuam.
Qhov tsim nyog
Vim tias cov iav yuav tsum tiv taus cov khoom loj thiab kev sib txhuam, lawv qhov chaw tau yooj yim puas los ntawm kev hnav thiab qaug zog. Tempering tuaj yeem txhim kho qhov hnav tsis kam, hardness thiab lub zog ntawm lub zog, yog li ua kom lub neej ua haujlwm ntawm lub zog. Nyob rau tib lub sijhawm, lub iav txias kuj tuaj yeem txhim kho qhov tseeb thiab ruaj khov ntawm cov iav, tsis txhob muaj suab nrov thiab kev vibration teeb meem tshwm sim los ntawm kev sib txhuam thiab hnav, thiab ua kom lub zog ua haujlwm zoo. Yog li ntawd, iav quenching thiab tempering plays lub luag haujlwm tseem ceeb hauv kev tsim cov tshuab thiab yog ib qho ntawm cov kev sib txuas tseem ceeb los xyuas kom meej qhov kev ua haujlwm ntawm cov cuab yeej siv tshuab.
iav tempering txoj kev
Tam sim no, cov txheej txheem tseem ceeb rau iav quenching thiab tempering muaj xws li nplaim taws quenching, dov quenching, carburizing quenching, ib-txoj kev rotation quenching, thiab lwm yam. cov khoom siv tshwj xeeb iav thiab cov xwm txheej siv.
Hauv kev xaus
Raws li cov ntsiab lus tseem ceeb ntawm kev sib kis, cov iav yuav tsum muaj qhov hardness txaus, lub zog, hnav tsis kam thiab corrosion kuj los xyuas kom meej lawv cov kev ua haujlwm ib txwm muaj. quenching thiab tempering yog ib txoj hauv kev zoo los txhim kho lub hardness, lub zog thiab hnav tsis kam ntawm cov iav, uas yog qhov tseem ceeb rau kev ntseeg tau thiab kev nyab xeeb ntawm cov cuab yeej siv tshuab. Yog li ntawd, nyob rau hauv machinery manufacturing, iav txias yog ib qho tseem ceeb ib feem.
