Mu gihe ibiciro bya zahabu mpuzamahanga bikomeje kuzamuka cyane, bikurikirwa n’ibiciro bya feza, abashoramari bo ku isi yose bashishikajwe n’amabuye y’agaciro arabagirana. Ariko, inyuma y’uyu munsi mukuru, ibikoresho by’inganda bisa nkaho bitazwi neza—imashini ikoresha icyuma gica ibintu mu buryo bw’ubusa—birimo kugaragara inyuma y’ibishushanyo, bikaba ingenzi mu kugena isoko, ndetse bikagera aho bigoye cyane kubibona.

1. Imashini ikoresha vacuum ingot casting ni iki?Ikora ibirenze icyuma gusa; ikora n'icyizere.

Mu magambo make, imashini ikoresha imashini icukura ikoresheje imashini icukura ikoresheje imashini ni igikoresho cyo mu rwego rwo hejuru gisuka icyuma gishongeshejwe mu mashini (cyangwa "ingots") zifite imiterere n'uburemere runaka munsi y'ikirere gifite imashini nyinshi cyangwa umwuka udafite umwuka.

Ushobora kwibaza uti: Gucana Ingot bisa n'ibyoroshye, none kuki bisaba akajagari n'ubuhanga bwinshi, bikorerwa mu buryo budafite ishingiro?

Ibi bireba ishingiro ry'ikibazo. Ku byuma by'agaciro nka zahabu na feza, ndetse n'ibyuma byihariye bifite isuku nyinshi, gucukura mu mwobo ufunguye bisanzwe bitera imbogamizi ebyiri zikomeye:

1. Oxidation n'imyanda:Umwuka uhura n'icyuma gishongeshejwe, kikarema ibishingwe hanyuma kikazana imyanda, bigagabanya ubuziranenge bw'ingot bigatera inenge z'imbere nko kuzura no gufungana kw'ibishingwe.

2. Kutamera kimwe mu bigize:Ibintu bimwe na bimwe bivangavanze bihita byoroshye gutakara mu kirere, bigatuma habaho utubumbe dufite imiterere idahuye n'imiterere n'imikorere idakwiye.

Imashini ikoresha icyuma gicana ibintu mu buryo bw'umwuka (vacuum ingot casting machine) ni yo mwanzi ukomeye w'ibi bibazo. Mu gukora "umwuka mwiza" hafi ya wose, bituma:

Ubuziranenge bukabije: Oxidation irakurwaho, bigatuma habaho uduce twinshi, dusa, kandi tudafite inenge.

Ibara ryiza: Imiterere ya shimi ya buri ngano yemejwe ko ihuye n'amahame agenga imiterere.

Isura nziza: Ubuso bw'indorerwamo bumeze nk'ubudodo n'ibimenyetso bisobanutse neza ni ibihangano by'ubuhanzi.

Bityo, ibicuruzwa bikorwa n'imashini ikora ibikoresho byo gukata ibintu mu buryo bwa vacuum ingot si ibikomoka ku zahabu na feza gusa; bitera icyizere ku isoko, bikwirakwiza amafaranga menshi, ndetse n'ibyemezo by'imari byemewe ku isi yose. Ni "ikimenyetso cy'ubuziranenge" bw'isi y'amabuye y'agaciro.

2"Isiganwa ry'ubushobozi" munsi y'izamuka ry'igiciro cya zahabu: Kuki bigoye cyane kubona imashini?

Iyo ibiciro bya zahabu na feza bikomeje kuzamuka, isoko rizatera urukurikirane rw'ibibazo:

1. Ubusabe bw'ishoramari buriyongera:Abashoramari b’ibigo n’abantu ku giti cyabo baguze zahabu na feza, kandi utubati twa zahabu na feza turakennye. Inganda zikora ibikoresho byo gukata za Ingot ziremereye cyane kandi zigomba kongera ubushobozi bwo gukora.

2. Ibisabwa ku rwego rw'igihugu:Banki nkuru nyinshi zikomeje kongera ububiko bwa zahabu. Izi ububiko bwa zahabu nazo zigomba gushyirwa mu bikoresho bya zahabu byujuje ibisabwa mpuzamahanga.

Incamake y'ibi byose bisabwa igaragaza isano imwe - gukata ingot. Ibikoresho by'ingenzi bishobora gukora ingot zigezweho kandi zishobora gutangwa ni imashini ikora imashini ikoresha amashanyarazi.

Rero, ikibazo cy'uko "bigoye kubona imashini" cyagaragaye mu buryo busanzwe:

(1) Inganda zigezweho, ubushobozi buke bwo gukora:Imashini zikoresha imashini zitunganya imashini zikoresha imashini zikoresha ikoranabuhanga rihambaye, zikoresha ikoranabuhanga rigezweho nko kubona imashini zikoresha ...

(2) Igihe kirekire cyo gutanga:Kuva ku gutumiza kugeza ku gutanga ibikoresho, kubishyiraho no kubishyiraho, uruziga rushobora gufata amezi menshi cyangwa arenga umwaka. Iyo isoko ribaye rikeneye cyane, ibyo bikoresho ntibishobora guhita bisubizwa.

(3) Ingaruka z' "Umuyoboro w'amazi":Ku nganda zitunganya imashini, uko zigira imashini zitunganya imashini zikoresha imashini zikoresha imashini zikora ...

Dushobora kuvuga ko ingano y'imashini zikora ibikoresho byo mu bwoko bwa vacuum ingot yabaye igipimo nyacyo kandi kigezweho cy'ubushyuhe bw'isoko ry'amabuye y'agaciro.

Umwanzuro: “Ingot Casters” ituje n'isoko ry'umuvuduko

Mu gihe imari shingiro ku isi yose yishimira cyangwa ihangayikishijwe n'ibiciro byose bya zahabu,imashini zikoresha icyuma gishyushya ingotZikora mu buryo butuje kandi buhamye mu ruganda. Ziracecetse, ariko kubera "ubuke" bwazo bwihariye, zigenzura neza umuhogo w'ibikoresho bifatika. Bitwibutsa ko munsi y'ingorane z'amasoko y'imari, hari imbaraga zikomeye z'inganda zishyigikira isi bucece. Ubutaha ubonye icyuma cya zahabu gishyushye, wenda tekereza ko urugendo rwacyo rwo guhanga rwari ruteye imbere cyane mu ikoranabuhanga kandi rukomeye kurusha uko twabitekereza, kandi ko "imashini icapa" yayiremye ubwayo yabaye ikimenyetso cyihariye cy'iki gihe.
