I. Internal Porosity nyob rau hauv Castings: Hidden Quality Hazards

Raws li lub hauv paus khoom siv rau machined qhov chaw, qhov zoo ntawm castings ncaj qha txiav txim siab qhov yooj yim ntawm machining tom ntej thiab kev ua tau zoo ntawm cov khoom tiav. Txawm li cas los xij, thaum lub sij hawm casting txheej txheem, vim muaj tej yam xws li cov roj tso tawm thaum lub sij hawm hlau solidification, tsim pwm tsis zoo, los yog kev tswj tsis txaus ntawm cov txheej txheem pouring, me me pores feem ntau tsim nyob rau hauv lub casting. Cov pores no, txawm tias me me, ua zoo li lurking "lub sijhawm foob pob," tsim kom muaj kev phom sij rau cov txheej txheem machining tom ntej.

II. Txiav Fluid Infiltration: Ib qho Catalyst rau Exacerbating Teeb meem

Thaum lub sij hawm machining, txiav kua ua lub luag haujlwm tseem ceeb hauv kev ua kom txias, lubrication, thiab tu. Txawm li cas los xij, thaum porosity muaj nyob rau hauv lub casting, txiav cov kua yuav nkag mus rau hauv ib feem los ntawm cov me me raws. Raws li cov kua txiav accumulates, nws cov tshuaj lom neeg cov khoom yuav hnov ​​​​mob nrog cov khoom siv casting, accelerating corrosion. Ntau qhov tseeb, kev txiav cov kua dej tuaj yeem ua rau muaj kev ntxhov siab tsis sib xws hauv cov casting, ua rau cov kab nrib pleb thaum siv los yog siv, cuam tshuam rau cov khoom tsim kev ncaj ncees thiab lub neej ntev.

III. Crack Tsim: Ib qho kev tshwm sim tsis pom kev ntawm kev sib cuam tshuam

Thaum txiav cov kua dej infiltration tshwm sim vim qhov porosity nyob rau hauv lub casting, tawg tsim yuav luag inevitable. Cov kab nrib pleb no tsis tsuas yog ua rau tsis muaj zog ntawm cov load-cov kabmob muaj peev xwm ntawm lub tshuab ua haujlwm tab sis kuj tuaj yeem dhau los ua qhov pib ntawm kev ntxhov siab, txuas ntxiv mus txog thaum qhov tsis ua tiav. Rau siab -precision, siab- load mechanical equipment, xws li ib tug zoo teeb meem yog undoubtedly tuag, cuam tshuam cov cuab yeej ua tau zoo tshaj plaws thiab ua rau muaj kev nyab xeeb xwm txheej phem tshaj.

IV. Kev Tiv Thaiv Cov Tswv Yim: Kev Tswj Xyuas Kom Zoo los ntawm qhov chaw mus rau txheej txheem

1. Optimize Casting Txheej Txheem: Txo cov porosity sab hauv hauv castings los ntawm kev txhim kho pwm tsim, kho cov dej tsis haum, thiab siv lub tshuab nqus tsev los yog siab casting.

2. Kev Tswj Xyuas Zoo: Ua kom muaj zog ua ntej- kev tshuaj xyuas cov khoom xa tuaj, siv X-ray flaw detection thiab ultrasonic kuaj tam sim los txheeb xyuas thiab tsis lees txais cov castings nrog qhov tsis zoo porosity loj.

3. Kev txiav txim siab xaiv cov kua dej txiav: Xaiv cov kua txiav nrog cov khoom zoo sib xws raws li cov khoom siv casting thiab cov txheej txheem machining kom txo tau qhov kev pheej hmoo ntawm corrosion los ntawm cov tshuaj tiv thaiv.

4. Txhim Kho Cov Txheej Txheem Saib Xyuas: Ua tib zoo saib xyuas kev siv cov kua dej txiav thaum lub tshuab ua haujlwm, hloov pauv thiab lim nws kom tsis tu ncua thiab tiv thaiv impurities los ntawm exacerbating corrosion ntawm castings.

5. Tom qab-Kev kho kom zoo: Ua kom muaj kev kho cua sov los yog kev kho saum npoo ntawm cov khoom siv, xws li kev txhaj tshuaj, carburizing, thiab quenching, txhawm rau txhim kho lawv cov kab nrib pleb thiab corrosion kuj.
