Kiyi yekugadzira upfu hwe VIGA Vacuum atomization
Nheyo yekugadzira michina yekugadzira upfu hwe vacuum atomization:
Kugadzira atomization yemuchina wevacuum kunoshanda nekunyungudutsa simbi nesimbi dzakasanganiswa pasi pemamiriro ekudzivirira kana gasi. Simbi yakanyungudutswa inoyerera ichidzika nepaburi rinonyungudutswa nemhepo inopinza uye nemuromo unotungamira, uye inogadziriswa uye inopwanywa kuita madonhwe akawanda akanaka nemhepo inoyerera nemhepo ine simba kuburikidza nemuromo. Madonhwe aya akanaka anooma kuita zvidimbu zvedenderedzwa uye zvepasi pedenderedzwa panguva yekubhururuka, izvo zvinozoongororwa uye zvinoparadzaniswa kuti zvigadzire hupfu hwesimbi hwezvikamu zvakasiyana-siyana.
Tekinoroji yehupfu hwesimbi ndiyo nzira inoshandiswa zvakanyanya pakugadzira zvinhu mumaindasitiri akasiyana-siyana.
Ma alloys anogadzirwa achishandisa poda metallurgy ane mashandisirwo akasiyana-siyana, akadai se welding and brazing alloys eindasitiri yemagetsi, nickel, cobalt, uye iron-containing high-temperature alloys yendege, hydrogen storage alloys uye magnetic alloys, uye active alloys, dzakadai se titanium, dzinoshandiswa mukugadzira sputtering target.
Matanho ekugadzira hupfu hwesimbi anosanganisira kunyungudutsa, kuita atomu, uye kusimbisa simbi dzinoshanda uye alloys. Nzira dzekugadzira hupfu hwesimbi, dzakadai sekuderedza oxide uye kuita atomization yemvura, dzinodziviswa nematanho emhando yepamusoro yehupfu, akadai se particle geometry, particle morphology, uye chemical purity.
Kugadzira hupfu husina simba, pamwe chete nekunyungudutsa kwevacuum, inzira inotungamira yekugadzira hupfu hwemhando yepamusoro hunosangana nezvinodiwa zvemhando yepamusoro.
Mashandisirwo eupfu hwesimbi:
Ma superalloys akagadzirwa ne nickel ekugadzira zvinhu zvemuchadenga nemagetsi;
Zvinhu zvekugadzirisa nekushongedza;
Mapfekero asingapfeki;
Upfu hweMIM hwezvikamu;
Kugadzira zvinhu zvemagetsi nenzira yekushambadzira;
MCRALY inorwisa oxidation coatings.
Zvimiro:
1. Madonhwe acho anooma nekukurumidza panguva yekudzika, zvichikunda kupatsanurwa uye zvichikonzera chimiro chimwe chete.
2. Nzira yekunyungudutsa inogona kugadziriswa. Nzira dzinosanganisira: kunyungudutsa kwepakati nepakati nechinhu chinonyungudutsa, kunyungudutsa kwepakati nepakati pasina chinhu chinonyungudutsa, kunyungudutsa nechinhu chinonyungudutsa chinodzivirira kupisa, uye kunyungudutsa kwearc.
3. Kupisa zvinhu zve alloy uchishandisa ceramic kana graphite crucibles zvinobudirira kunovandudza kuchena kwezvinhu kuburikidza nehunyanzvi hwekunatsa nekuchenesa.
4. Kushandiswa kwe supersonic tight coupling uye tekinoroji ye gas atomizing nozzle inogonesa kugadzira ma micro-powders akasiyana-siyana e alloy.
5. Kurongwa kwemadutu ane matanho maviri uye dhizaini yehurongwa hwekuunganidza zvinhu zvinovandudza goho rehupfu hwakatsetseka uye kunoderedza kana kubvisa kuburitswa kweguruva rakatsetseka.
Kuumbwa kweChigadziko Chekugadzira Upfu hweVacuum Atomization:
Dhizaini yakajairika yeVacuum Atomization Powder Making System (VIGA) inosanganisira vacuum induction melting (VIM) furnace, umo alloy inonyungudutswa, inonatswa, uye inobviswa gasi. Simbi yakanyungudutswa yakanatswa inodururwa mujet pipe system kuburikidza ne preheated tundish, uko kuyerera kwakanyungudutswa kunoparadzirwa ne high-pressure inert gas flow. Upfu hwesimbi hunobuda hunosimba mukati meatomizing tower, iri pasi pe atomizing nozzles. Musanganiswa weupfu-gasi unoendeswa kuburikidza nepombi yekuendesa kune cyclone separator, uko upfu hwakakora uye hwakatsetseka hunoparadzaniswa neatomizing gas. Upfu hwesimbi hunounganidzwa mumudziyo wakavharwa uri pasi pe cyclone separator.
Rudzi urwu runotangira padanho remurabhoritari (10-25 kg inokwana crucible capacity), giredhi repakati rekugadzira (25-200 kg inokwana crucible capacity) kusvika kumasystem makuru ekugadzira (200-500 kg inokwana crucible capacity).
Midziyo yakagadzirirwa iwe inowanikwa kana ukaikumbira.
