Indlela yokuxazulula i-slag enamathelayo lapho usika ipuleti le-aluminium nge-laser

I-laser cutting aluminium slag (eyaziwa nangokuthi i-hanging slag, i-slag) iyinkinga evamile, ikakhulukazi ngenxa yokushisa okuphezulu kwe-aluminium, indawo yokuncibilika ephansi, i-oxidation elula kanye ne-melt state viscosity kanye nezinye izici. Ukuze kuxazululwe inkinga ngendlela ehlelekile, kubalulekile ukwenza ngcono igesi, amapharamitha, izinto zokwakha, imishini kanye nenqubo 5. Okulandelayo kunikeza isethi ephelele yezixazululo:

Ukhiye oyinhloko: ukukhethwa kwegesi okusizayo kanye nokwenza ngcono (lena yingxenye ebaluleke kakhulu)

1. I-nitrogen emsulwa kakhulu iyathandwa

• Isimiso: I-nitrogen njengegesi engasebenzi kahle ingavimbela ngempumelelo ukushibilika kwe-aluminium encibilikayo futhi inciphise ukwakheka kwe-aluminium oxide (Al₂O₃) sticky residue. Ngesikhathi esifanayo, i-nitrogen enomfutho ophezulu ingaphephula uketshezi lwe-aluminium oluncibilikisiwe luye phansi lusuka endaweni evulekile, kunokuba luqongeleleke eceleni.
• Imfuneko yobumsulwa: ≥ 99.99% (kunconywa 99.995% noma ngaphezulu). Ukuntuleka kobumsulwa kungenye yezimbangela eziyinhloko zokunamathela kwe-slag.
• Izidingo zokucindezela: ngokuya ngokulungiswa kobukhulu bepuleti, ngokuvamile ziphakeme (njengokusika ipuleti le-aluminium elingu-3mm libe ngu-1.5-2.0MPa). Ukucindezela okunganele akukushisi kahle ukuncibilika.

2. Umoya ocindezelwe osezingeni eliphezulu (indlela engabizi kakhulu)

• Izimo ezisebenzayo: izidingo zekhwalithi ephansi ebusweni aziphezulu, noma azikho ipuleti le-aluminium elincane (njenge-≤ 3mm) imishini eqinile.
• Izimo ezidingekayo:
• Kumelwe ifakwe imishini yokomisa efrijini esebenza kahle kakhulu kanye nezihlungi ezinembile ukuqinisekisa ukuthi umoya awunamanzi futhi awunawo uwoyela. Umswakama namafutha kuzokhulisa ukugaywa kwe-aluminium kanye nokunamathela kwe-slag.
• Ingcindezi kufanele iqine ngokwanele.

3. I-oksijini (inhloso ekhethekile)

• Isimiso: Sebenzisa ukusabela kwe-oxidation ukuze unikeze ukushisa okwengeziwe futhi wandise isivinini sokusika. Kodwa-ke, inani elikhulu le-slag ye-alumina eqinile neqinile lizokhiqizwa ngokungenakugwenywa, okuvame ukunganconywa ekusikeni okudinga ukunamathela kwe-slag, kodwa kuphela ngezikhathi ezidinga izidingo eziphansi kakhulu zobuso noma ukucutshungulwa okulandelayo.

ukusika nokwenza ngcono ipharamitha

Amapharamitha kufanele afaniswe negesi ukuze kulungiswe iphutha lesistimu.

1. Ibhalansi yamandla nesivinini:

• Amandla aphezulu kakhulu/isivinini sihamba kancane kakhulu: amandla amaningi abangela ukuncibilika ngokweqile kwe-aluminium, ichibi elincibilikisiwe liba likhulu, igesi kunzima ukuyiphephula, futhi kwakheka i-slag eyindilinga engezansi.
• Amandla aphansi kakhulu/ashesha kakhulu: amandla anele, izinto azinqunywanga noma iphansi lipholiswe ngokushesha kakhulu, ukuncibilika kuzoqina onqenqemeni ngaphambi kokuba kupheshulwe umoya.
• Indlela yokulungisa iphutha: ngokusekelwe kumapharamitha anconyiwe, ukuhlolwa kweleveli yesivinini kwenziwa ukuthola "indawo enhle" enqamula nje futhi ilenga i-slag encane kakhulu ".

2. Ukuphindaphinda kanye nomjikelezo womsebenzi:

• Ukunciphisa imvamisa nokulungisa umjikelezo womsebenzi ngezinye izikhathi kusiza ukulawula okufakwayo kokushisa nokunciphisa ukushisa okuphansi. Kumapuleti amancane, kungasetshenziswa imvamisa ephezulu.

3. Indawo yokugxila:

• Zama ukunciphisa ukugxila kancane (ukungagxili kahle) ukuze amandla agxile kakhulu engxenyeni engezansi yepuleti, okusiza ekuqhumeni ukuncibilika kusuka phansi. Lena indlela ephumelelayo yokuthuthukisa i-slag elenga phansi. Kudingeka ilungiswe kahle ngokwesimo sangempela.

Isimo Semishini Nezinto Ezisetshenziswayo

1. Ukuhlolwa nokukhetha kwe-nozzle:

• Isimo: Qinisekisa ukuthi umlomo awugugi, awugugi futhi awugugi phakathi nendawo. Umlomo ogugile uzokwenza ukuthi ukuhamba komoya kuphazamiseke futhi ukushaywa kwe-slag kube buthaka.
• Ububanzi: ngokuvamile sebenzisa i-nozzle enkulu enobubanzi (njenge-φ2.0mm noma ngaphezulu) ene-nitrogen enomfutho ophezulu, ingakha ukumbozwa okuqinile nokubanzi kwesithiyo sokugeleza komoya.

2. Ikhwalithi yogongolo:

• Qinisekisa ukuthi ilensi yekhanda le-laser (isibuko esigxilile, isibuko esivikelayo) ihlanzekile futhi ayinayo ingcoliso, futhi uqinisekise ukuthi ukusatshalaliswa kwamandla okukhanya kuyafana futhi kugxilile.

Ukulungiselela izinto kanye nenqubo

1. Ubuso kanye nezinto zepuleti le-aluminium:

• Ukuhlanza: Susa uwoyela, uthuli kanye nengqimba ye-oxide ebusweni bepuleti le-aluminium ngaphambi kokusika. I-ejenti yokuhlanza ekhethekile ye-aluminium alloy ingasetshenziswa.
• Ibanga le-alloy: ukusebenza kwe-aluminium alloy okuhlukile kuhlukile. Ngokuvamile uchungechunge olu-5 (njenge-5052) kunochungechunge olu-6 (njenge-6061) lungcono ukusika, i-slag encane enamathelayo. I-Silicon, i-magnesium nezinye izakhi ze-alloy viscosity ephezulu zinkulu.
• Isendlalelo se-oxide: uma kunesikhumba se-oxide esijiyile ebusweni bepuleti, singapholishwa kancane noma sifakwe ukhilimu.

2. Ibanga lokusebenza:

• Qinisekisa ukuthi ibanga elisuka ku-nozzle liye epuletini lihlala linjalo futhi lifanelekile (ngokuvamile liyi-0.5-1.5mm). Ukuphakama kakhulu kuzonciphisa ingcindezi yegesi.

3. Ukubhoboza kanye nomthofu:

• Lungiselela amapharamitha okubhoboza ukuze uvimbele ukuchitheka ekuqongeleleni phezulu ngesikhathi sokubhoboza.
• Sebenzisa ama-lead angaphandle noma ama-lead e-arc ukuze ugweme ukunqwabelana kwama-slag ekuqaleni komklamo we-workpiece.

Ukwelashwa ngemva kokusikwa (isenzo sokulungisa)

Uma kusekhona ukulenga okuncane kwe-slag, izinyathelo ezilandelayo zingathathwa:

1. Ukususwa ngokoqobo:Sebenzisa i-scraper, ibhulashi lensimbi engagqwali noma iphedi yokukhuhla ukuze ususe ngesandla. Ukuze uthole i-slag eqinile yepuleti elisindayo, kungadingeka i-grinder encane ye-engela enesondo elikhethekile le-nylon.

2. ukuhlanza ngamakhemikhali:Ukusetshenziswa koketshezi olukhethekile lokuhlanza i-aluminium noma isixazululo se-alkaline esixutshwe amanzi, kungancibilikisa ingxenye ye-slag enamathelayo. Khumbula ukugwema ukusebenzisa ama-asidi aqinile nama-alkali, futhi ngemva kokwelashwa kumele kuhlanzwe kahle ngamanzi bese komiswa.

3. Ukuqhuma kwesihlabathi:Ezingxeni ze-batch noma ezidinga ubuso obufanayo obungacwebezeli, isihlabathi esincane (njengezinhlayiya zeglasi) singasetshenziswa ekuqhumiseni isihlabathi.

Ngophenyo oluhlelekile kanye nokwenza ngcono okungenhla, inkinga yokunamathela kwe-slag yepuleti le-aluminium lokusika nge-laser ingalawulwa ngempumelelo ukuze kufezwe ukusika kwekhwalithi ephezulu. Isihluthulelo ukuqonda ukuthi "ukuhlanza ngempumelelo igesi ehlanzekile kakhulu" kuyingqikithi, futhi zonke ezinye izilinganiso zihlanganiswa kulo mgogodla owodwa.
