VIM-HC Vacuum Induction Electromagnetic Levitation Melting

Intangiriro y'icyitegererezo

Ikwiriye gushonga no gutwika ibikoresho bikora nka titaniyumu, zirconium, superconductors, ibikoresho byo kubika hydrogen, alloys za shape memory, alloys intermetallic n'ibikoresho bishyuha cyane.

Ibirango by'ibicuruzwa

Porogaramu:

• Imitwe y'ikipe ya Golf ikozwe muri titaniyumu;

• Valve z'imodoka za titanium-aluminium, amapine ya turbocharger ashyushye cyane;

• Ibice by'inyubako na moteri by'inganda z'indege (titanium castings);

• Implants zo kwa muganga;

• Gukora ifu y'icyuma ikora;

• Pompe castings na valves zikozwe muri zirconium, zikoreshwa mu nganda z'imiti n'ubucukuzi bwo mu mazi, n'ibindi.

Ihame ryo gushonga kw'ingufu:

Ifuru ishongesha ikoresheje amashanyarazi ya VIM-HC ishyira icyuma gishongeshwa mu murima w’amashanyarazi uhindagurika cyane cyangwa uhindagurika hagati ukozwe na coil y’induction mu gihe cy’umwuka ushyushye. Icyuma gikonjeshwa n’amazi gikora nk' "ikinyabutabire" cy’umurima wa rukuruzi, cyibanda ku ngufu z’umurima wa rukuruzi mu bunini bw’icyuma gishongeshwa. Ibi birema imigezi ikomeye hafi y’ubuso bw’umuriro, birekura ubushyuhe bwa Joule kugira ngo bushongeshe umuriro kandi icyarimwe bigakora umurima wa Lorentz ushongesha (cyangwa semi-levates) kandi ugakurura umwuka ushyushye.

Bitewe n'ingufu za rukuruzi, gushonga gutandukana n'urukuta rw'imbere rw'icyuma gishongesha. Ibi bihindura imikorere y'ubushyuhe hagati y'icyuma gishongesha n'urukuta rushongesha kuva ku gukwirakwiza imirasire kugeza ku mirasire, bigabanya cyane igipimo cyo gutakaza ubushyuhe. Ibi bituma gushonga kugera ku bushyuhe bwinshi cyane (1500℃–2500℃), bigatuma biba byiza gushonga ibyuma bifite aho bishongesha cyangwa ibyuma byabyo.

Ibyiza bya tekiniki:

1. Gushonga
Guhindura no gushyiramo imvange;

Gukuraho imyuka no kuyitunganya;

gushonga mu buryo bworoshye (gushonga mu buryo bwo guhagarika ibyuma);

Gusubiramo ibintu;

Gutunganya ubushyuhe, gutunganya ahantu hashongeshejwe, no gutunganya ibintu by'icyuma hakoreshejwe uburyo bwa distillation;

2. Gutera icyuma
Guhindura imiterere y'amabara mu cyerekezo;

Gukura kwa kristu imwe;

Gutanga ibyuma neza;

3. Ikorwa ryihariye rigenzurwa
Gucukura mu buryo buhoraho hakoreshejwe imashini (imigozi, amasahani, imiyoboro);

Gucana imigozi y'icyuma gikozwe mu cyuma (vacuum strip casting);

Gukora ifu y'ifu ikoresha amashanyarazi;

Ishyirwa mu byiciro ry'ibicuruzwa:

* Guhagarika umuriro w'itanura mu gihe cyo gushongesha birinda ubwandu hagati y'umuriro n'urukuta rw'icyuma, bigatuma biba byiza kubona ibikoresho by'icyuma n'ibitari ibyuma bifite isuku nyinshi cyangwa bishobora gukora cyane.

* Gukangura amashanyarazi mu gushonga bitanga ubwumvikane bwiza bw'ubushyuhe n'imiti.

* Kugenzura ubushyuhe n'ingufu bishongeshejwe hakoreshejwe umuyoboro uri hagati cyangwa hejuru uva kuri induction coil bitanga ubushobozi bwo kugenzura neza.

* Ubushyuhe bwinshi bwo gushongesha, burenga 2500℃, bushobora gushongesha ibyuma nka Cr, Zr, V, Hf, Nb, Mo, na Ta.

* Gushyushya hakoreshejwe uburyo bwa induction ni uburyo bwo gushyushya butagira aho buhuriye n’ibintu, hirindwa ingaruka n’ihindagurika ry’ikirere riterwa n’uburyo bwa plasma cyangwa uburyo bwa electron bushyushya icyuma gishongeshejwe n’icyuma gishongeshejwe.

* Imikorere yuzuye, harimo gushongesha, gusuka hasi, gusuka mu buryo bwo kuzunguruka, no gushyushya, kandi ishobora gushyirwamo ibikoresho byo gushyushya bihoraho, ibikoresho byo gukurura billet bihoraho, n'ibikoresho byo gusuka mu buryo bwo hagati (ni ngombwa).
