Cov nyhuv ntawm workpiece thiab cov cuab yeej siv ntawm cov cuab yeej hnav hauv kev ua si ntoo
- Cov nyhuv ntawm cov xwm ntawm workpiece raug txiav
Qhov ceev ceev yog ib qho ntawm cov khoom siv lub cev thiab cov neeg kho tshuab ntawm cov ntoo thiab muaj cov txiaj ntsig me me ntawm kev hnav cov cuab yeej. Rau cov khoom nws tus kheej kom raug txiav, cov khoom siv uas yuav tsum tau txiav txim siab muaj raws li nram no: Cov ntsiab lus ntoo ntoo, Silicon oxide lossis silication cov ntsiab lus, extract sib xyaw thiab cov ntsiab lus. Feem ntau, cov kev txiav ntawm cov ntoo qhuav yog qhov loj dua li tias cov ntoo nyoos, tab sis thaum txiav cov ntoo tsis-silicon, cov ntoo wood txiav cov cuab yeej loj dua. Ntawm qhov tod tes, thaum txiav cov cuab yeej ua los ntawm cov khoom siv steel hlau uas tsis tau siv cov khoom lag luam silicon Tus nqi ntawm cov dej tawm ntawm cov ntoo feem ntau tsawg dua 7, uas yog vim li cas cov khoom siv ua kom qhuav 4 xyoos, nws txoj kev nyiam ntau dua. Lwm cov khoom sib txawv uas tuaj yeem chelate nrog cov khoom siv twj tseem tuaj yeem nce cov cuab yeej hnav. Qhov kev hnav corrosion corrosion yog ua tau zoo dua hauv kev tsim kho corrosion nrog rau kev txiav, thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob yog nce, yog li cov hnav txo qis. Cov nplaum thiab cov fillers siv nyob rau hauv cov khoom ntoo, nrog rau cov khoom txawv teb chaws xws li cov xuab zeb me me sib xyaw ua ke sib xyaw thiab tsim khoom tuaj yeem ua rau lossis ua haujlwm dua
- Cov nyhuv ntawm cov cuab yeej
Nyob rau hauv ib txwm muaj xwm txheej, qhov ntau dua lub hardness ntawm cov khoom siv, piv nrog alloy tuam steel hlau yog me me, thiab cov cemented carbide yog me dua. Txawm li cas los xij, tseem muaj cov neeg uas tsis ua raws li txoj cai no, tsis yog tsim nyog carbide, tsis yog kev ua kom muaj zog, tus nqi ntawm kev hnav yuav tsum yog me me. Yog hais tias lub tungsten carbide txoj kab uas hla hauv cov ntxhib cov khoom siv tau nce, thiab cov nqi ntawm hnav thiab hle yog nce ntxiv. Cov kev sib raug zoo ntawm kev nyuaj thiab hnav tseem thim rov qab hauv cov cuab yeej hlau. Xws li cov cuab yeej twj uas muaj cov khoom loj ntawm carbide, nws tag nrho hardness yog qhov me me, tus nqi yuav kuj tseem me me. Yog li hardness thiab hnav tsis yog txoj kev sib raug zoo linear yooj yim.
Cov khoom siv lub cev uas cuam tshuam rau cov cuab yeej ntawm cov khoom siv hluav taws xob, qhov tseeb ntawm cov khoom siv hluav taws xob, cov cuab yeej siv hluav taws xob sib txawv, cov kab mob chromium tom qab cov cuab yeej sib txawv, cov cuab yeej tsuas yog hnav Nyob rau hauv sab xub ntiag rab riam, uas tuaj yeem qeeb qeeb ntawm txoj hlua ntawm rab riam ntug.
Muaj ntau ntau lwm yam uas cuam tshuam rau cov cuab yeej hnav, thiab peb cov noob tau mob siab muab cov kev daws teeb meem ntau dua.
