Aluminium tuag casting yog hais txog casting txhuas lossis aluminium alloy rhuab mus rau lub xeev ua kua rau hauv kab noj hniav los ntawm cov xuab zeb pwm lossis hlau pwm kom tau txais cov khoom txhuas los yogaluminium alloy qhov chawntawm ntau yam duab thiab ntau thiab tsawg. Cia peb tham txog cov txheej txheem polishing ntawm txhuas tuag castings thiab qhov ua rau thiab kev daws teeb meem ntawm cov pob dub ntawm polishing
Aluminium tuag casting txheej txheem polishing:
- Mechanical polishing: yog hais txog kev siv lub cev, xws li txiav, sib tsoo, thiab lwm yam, kom plastically deform lub aluminium nto kom cov convex qhov chaw sau cov concave qhov chaw, yog li txo thiab smoothing aluminium nto roughness thiab txhim kho cov khoom. aluminium nto roughness. Txawm li cas los xij, mechanical polishing ua rau kev puas tsuaj thiab kev puas tsuaj ntawm cov muaju ntawm cov hlau, uas ua rau cov txheej txheem plastically deformed, thiab cov microstructure hloov vim cov cua sov hauv zos.
- Electrolytic polishing: Electrolytic polishing yog siv tshuaj lom neeg cov tshuaj tiv thaiv rau hauv lub cell ntawm electrolytic nrog electrolytic polishing li yang thiab insoluble hlau li yin. Los ntawm cov tam sim no ncaj qha, cov anodic alumina dissolves, kom cov alumina nyob rau saum npoo ntawm aluminium plhaub ploj los ntawm txhuas plhaub thiab rov qab nws cov luster.
- Tshuaj polishing: Tshuaj polishing yog tshuaj etching nyob rau hauv tshwj xeeb tej yam kev mob. Nws yog los tswj cov kev xaiv dissolution ntawm txhuas nto, thiaj li hais tias lub microscopic tsa qhov chaw nyob rau hauv lub txhuas nto yog preferentially yaj, thiaj li mus cuag lub hom phiaj ntawm ib tug du thiab kaj nto.
Vim li cas thiaj muaj cov pob dub thaum txhuas tuag castings yog polished?
- Oxidation: Aluminium muaj lub siab nyiam oxidize. Thaum lub txhuas nto yog nyob rau hauv kev sib cuag nrog huab cua, ib tug oxide txheej yog yooj yim tsim. Cov txheej oxide no yuav tsis yooj yim tshem tawm thaum polishing, ua rau muaj qhov tsaus nti ntawm qhov chaw.
- Txheej Residue: Thaum lub sij hawm tsim cov txhuas tuag castings, txheej xws li xim los yog txheej tiv thaiv yuav raug siv los tiv thaiv nto ntawm casting. Cov txheej txheem no yuav tsis raug tshem tawm tag nrho thaum polishing, ua rau muaj qhov tsaus nti.
- Cov ntaub ntawv tsis sib xws: tej zaum yuav muaj cov khoom tsis sib xws los yog suav nrog hauv txhuas tuag castings. Cov inhomogeneities no yuav tshwm sim raws li qhov tsaus me ntsis lossis qhov chaw tsis sib xws thaum polishing.
- Rust los yog Contamination: Yog tias cov txhuas tuag casting muaj xeb los yog qhov chaw paug, xws li kev sib cuag nrog lwm cov hlau los yog raug rau cov tshuaj, cov txheej txheem polishing yuav tsis muaj peev xwm tshem tawm cov xeb los yog cov kab mob no, ua rau muaj qhov tsaus ntuj.
- Cov kev daws teeb meem rau cov teeb meem no yuav suav nrog kev siv cov txheej txheem polishing kom zoo thiab cov ntaub ntawv, tshem tawm cov khoom seem, siv cov khoom siv zoo dua thiab kev tswj cov txheej txheem tsim khoom, thiab ua kom lub ntsej muag zoo thiab pom tseeb thaum lub sij hawm casting fabrication.
Yuav ua li cas los daws qhov teeb meem ntawm cov pob dub thaum txhuas tuag castings yog polished?
Kev daws teeb meem ntawm cov pob dub thaum polishing txhuas tuag castings yuav xav tau kev xav txog ntau yam, thiab kev kho kom haum thiab kev sim. Qhov kev daws teeb meem kawg yuav tsum tau ua kom haum rau qhov xwm txheej tshwj xeeb, tshuaj xyuas, thiab ua kom zoo raws li qhov xwm txheej tiag tiag.
- Kev Npaj Nto: Kev npaj kom zoo yog qhov tseem ceeb ua ntej pib polishing. Xyuas kom meej tias qhov saum npoo ntawm aluminium tuag casting yog huv si thiab tshem tawm cov oxide txheej, txheej residue, cov kab mob, thiab lwm yam. Qhov tsis zoo ntawm qhov chaw tuaj yeem raug tshem tawm los ntawm kev ntxuav nrog cov tshuaj detergents los yog cov kuab tshuaj, los yog los ntawm kev siv tshuab xws li kev sib tsoo.
- Polishing txheej txheem xaiv: Nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov txheej txheem polishing tsim nyog thiab cov cuab yeej. Polishing yog ua los ntawm cov khoom siv abrasives thiab polishing, nrog rau kev ceev ceev, siab, thiab lubricants. Nyob ntawm qhov xwm txheej tshwj xeeb, cov txheej txheem polishing sib txawv tuaj yeem sim, xws li phau ntawv polishing, mechanical polishing, lossis tshuaj polishing, txhawm rau nrhiav txoj hauv kev zoo tshaj plaws.
- Tswj polishing lub sij hawm thiab kub: Ntau lub sij hawm polishing los yog siab polishing kub yuav ua rau overheating thiab oxidation ntawm txhuas nto, uas ua rau tsaus me ntsis. Tswj polishing lub sij hawm thiab kub los xyuas kom meej polishing tej yam kev mob.
- Txhim kho Cov Khoom Siv thiab Cov Txheej Txheem Tsim Khoom: Yog tias cov xim dub yog qhov tshwm sim tsis tu ncua, kev txhim kho cov khoom siv thiab cov txheej txheem tsim khoom yuav tsum tau txiav txim siab. Xaiv cov khoom siv aluminium purer kom txo tau qhov sib xyaw thiab tsis sib xws. Nyob rau tib lub sij hawm, casting thiab machining txheej txheem yog optimized los txo deg defects thiab paug.
