Yiziphi Izimfuneko Zemishini Ehlangabezana Nezidingo Zokukhiqiza UPhawu Lwensimbi Oluhlobene Ne-Aluminium Powder?

Isikhathi:27 Septhemba 2025

Ukukhiqiza uphondo lwe-aluminium lwezinga lemetallurgical kudinga imishini enekhono elithile elihlosiwe ukubhekana ne-akhawunti ye-aluminium futhi kuhlangabezane nezindinganiso quality. Nansi imishini eyisisekelo edingekayo ekukhiqizeni uphondo lwe-aluminium:

1. Izinsiza Zokwakha Amathoni

Ukusika kuyinqubo eyinhloko yokukhiqiza uphondo lwe-aluminium. Izindlela ezimbili ezivame ukusetshenziswayo yikhasi lokusika kanye nokusika kwe-centrifugal.

• Umshini Wokuhlukanisa Igazi:

  • Umkhiqizo Wengcindezi:Izinhlelo zegesi ezinamandla aphezulu, ngokujwayelekile i-nitrogen noma i-argon, eziyakwazi ukuphatha u-40–200 bar noma ngaphezulu.
  • Umphunga Wokunembile:Izinsimbi eziklanyelwe ngokukhethekile zokuphonsa u-aluminium oshisayo zibe yizithako ezincane.
  • Uhlelo Lokupholisa:Ukushisa ngokushesha ukuze kuqine. Izinhlelo ezicebile ngentokazi yamanzi noma umoya opholile ngokwamanzi kuvame ukufunwa.
  • Izinto Zokwakha:Izakhi eziphezulu ze-stainless steel noma ama-alloy anokw withstand umusi woshukela ukuze izingxenye ezithintwe yi-aluminium echichimayo.

• Imishini Yokuhlukanisa I-Atomization nge-Centrifugal:

  • Ijubane Lokujikeleza:I-disk ethakazelisayo esheshayo (20,000+ RPM) yokwenza i-aluminium ibe yizicucu ezincane.
  • Impahla YeDiski:Izinto eziqinile, ezimelana nokushisa ezifana ne-tungsten carbide noma insimbi engenasici.
  • Ukulawulwa Kweshisayo:Ukulawulwa kahle kokushisa kwe-aluminium ehlanganisiwe, ngokuvamile phakathi kuka-660–780°C.

2. Izitofu Zokuhlanza

Ukukhiqizwa kwempuphu ye-aluminium kuqala ngokushishela i-aluminium elRaw. Izidingo zamafurnace okushisa zihlanganisa:

• Ikhono:Usayizi ofanele ukukhipha inani elidingekayo lesigaba (ivamise ukuba ngezithasiselo ezinkulu).
• Uhlelo Lokushisa:Imishini yokushisa ye-elekthronikhi noma izinhlelo ezishiswa ngogesi ezakhiwe ukuhlukumeza i-aluminium.
• Ukulawulwa Kweshisayo:Ama-thermocouple noma amapyrometer ukuze kulungiswe kakhulu izinga lokushisa.
• Imathiriyali yeCrucible:Graphite, silicon carbide, noma i-ceramic engavumi ukungcoliswa.
• Izici Zokuphepha:Ukuvikela kokushisa kakhulu nokubamba ukugeleza.

3. Ukusiza nokuhlukaniswa kobukhulu be-particle

Ukuze kuhlangabezane nezindinganiso ze-metallurgical-grade, ama-aluminium powders kumele ahlukaniswe ngokunembile ngosayizi.

• Umshini Wokuhlola Ngomoya Oguquguqukayo:

  • Usayizi weMesh:Izihlungi ze-micron-grade (isb. 10–400 microns, kuye ngencazelo yeph powdered).
  • Ukusebenza Kokuhlunga:Ukushintshashintsha okwenziwa ngezinyathelo eziningi okunvayo ngokwezinga eliphezulu lokuthuthwa.
  • Ukwakhiwa:Izinto eziphikisa ukugqwala futhi ezingangeni emzimbeni ukuze ziphathe ama-particulu alimini acwengekayo.

• Umhlukanisi Womoya:

  • Ukucacisa Kokunciphisa:Kulungiswe ukuze kuqondiswe kahle usayizi wezinto (kuze kube nokunemba okukhulu kwezinsalela).
  • Uhlelo lwe-Airflow:Umoya ophathwayo ukuze uhlukanise uphondo olunomile kahle.

4. Izinsiza Zokuhlikihlelela Nokubhoboza

Ukuhlanzwa kosayizi bamaphetshana:

• Imishini yeBall noma Imishini yokucindezela:

  • Ukufaneleka Kwezinto:Izisekelo ezingaphenduli (isb. polyurethane noma ceramics) ukuze kugwenywe ukungcoliswa.
  • Ukugaya Okuphakathi:Insimbi engenashubhu, i-zirconia, noma ezinye izinto ezinokumelana okuphezulu.
  • Ukulawulwa kwejelo:Izinhlelo ezihamba ngokushintsha isivinini ukuze zisebenze ngempumelelo.

• Amathuluzi Okumayisha Ijeti:

  • Uhlelo Lomoya Ocolekileyo:Kudinga umoya ohlanzekile, owomile, ophakeme ngok压力 (osezingeni elingama-120 psi noma ngaphezulu).
  • Ukuphuma Kwenza:Ikhono lokugaya amagama abe usayizi ongaphansi kwe-micron.

5. Izinhlelo zokwelapha indawo nezinsiza zokufaka imicu

Uma kudingeka, amapoda e-aluminium angafakwa ungqimba lwezicelo ezithile.

• Ukuxuba nokumboza Imishini:
  • Ukuxuba Okufanayo:Amamixa aphezulu ukuqinisekisa ukusabalalisa okufanayo kwamakhemikhali noma izengezo.
  • Ukukwazi Ukumisa:Izinsiza zokomisa ezihlanganisiwe noma izilungiselelo zokhukhuleka zamaphowder anesithukuthuku sokwazisa.

6. Izinhlelo Zemvelo Nezokuphepha

Ukuphatha uthuli lwe-aluminium kudinga ukuvikeleka ngenxa yokuthi luphumelela ukuvutha nokuphosa.

• Izinhlelo Zokuhlanganisa Ubuqhawe:

  • Ukuhlanzwa komoya okuhamba phambili kanye nokuqoqwa kukashukela ukuvimbela ukuhlanganiswa kwepudi.
  • Izinhlelo zokuvikela ukuqhuma (ezihambisana ne-ATEX) zokusebenza ngokuphephile.

• Ukulawulwa KweNhliziyo Engashintshi

  • Izinhlelo zokugcina umoya ongekho nhlobo ezindaweni zokucubungula ukuze kuvinjelwe ukushintsha kwesimo sokungena kokushisa kanye nobungozi bomlilo (isb. ukuhlanza nge-nitrogen noma i-argon).

• Izinhlelo Zokunciphisa Umlilo:

  • Izindlela zokuphepha zomlilo ezithuthukisiwe ezifana nezinhlelo zokucima umlilo ze-CO2 noma zezinhlaka ezingazweli.

7. Imishini Yokulawulwa Kwesimo

Ukuqinisekisa ikhwalithi yompowder yekhwalithi ye-metallurgical kudinga amathuluzi okuhlaziywa.

• Umhlaziyi Osayizi WamaPhaketheI-sistimu yokuhlula i-laser noma yokuhlangana kokukhanya okunamandla ukuze kuthathwe futhi kuqinisekiswe ukusabalala kosayizi wezicucu.
• Izilinganisi Zokunisela:Ukuze kuqinisekiswe ukuthi kukhona umswakama omncane em粉.
• Izimoto zeSpectrometer:Izinhlelo ze-XRF, OES, noma i-ICP zok verifying ubunjalo bokwakheka kwemichilo.

8. Imishini Yokweseka

Izinhlelo ezengeziwe zokukhiqiza okunembile:

• Izinsiza zokuhambisa impahla.
• Izindawo zokugcina eziheha ukudlula ezivimbela ukuvala.
• Izinsiza zokuphakelayo ezizenzekelayo zokukhiqiza okuqhubekayo.

Ukuhambisana neziNqubomgomo

Imishini kumele ihlangabezane nezindinganiso ezifanele zokuphepha nemithetho yokuvikela imvelo, njengokufana:

• Izindinganiso ze-ISO zendlela ye-powder metallurgy.
• Ubufakazi bokuphepha kokuphahlazeka (ATEX, ukuhambelana ne-NFPA).
• Ukuqinisekiswa kwe-CE emakethe yaseYurophu.

Ngokwespecifici ezingaphezulu, imishini kufanele ikwazi ukukhiqiza uthuli lwe-aluminium oluphakeme, olufanele izicelo ze-metallurgical-grade ngenkathi iqinisekisa ukuphepha nokusebenza kahle.

Thintana Nathi

I-Shanghai Zenith Mineral Co., Ltd. iyinkampani ehamba phambili yokukhiqiza imishini yokuphuca nokugaya eChina.
