Umutekano muke wubatswe kubaka ikirahure ubushyuhe bwuzuye ikirahure
Ikizamini cyo gushyushya ubushyuhe (HST)
Kwiyiturika-ibirahuri bituje
Ikirahureifite inenge yihariye yo "kwiyitirira" - ikirahure cyitondewe mugihe hatabayeho ibikorwa bitaziguye kandi byahise bivunika. Muburyo bwo gutunganya ubushyuhe, kubika, gutwara, kwishyiriraho, gukoresha, nibindi, kugabanya ikirahuri cyo guturika gishobora kubaho. Ibigezwehoikirahure kirerembatekiniki yo kubyaza umusaruro ntishobora gukuraho burundu kuba hari nikel sulfide (NiS), bityo rero kwishishanya-guturika byanze bikunze, ibyo bikaba ari ibintu biranga ikirahure. Kugeza ubu, nta rwego rw'igihugu icyo ari cyo cyose ku isi kigabanya kwiyahura kw'ibirahure bikaze. Ukurikije ubunararibonye bw’inganda z’ibirahure mu Bushinwa, igipimo cyo kwiyahura cy’ikirahuri gisanzwe gikaze ni 3 ~ 5 ‰. Mu rwego rwo kwirinda ko habaho guturika kwikirahure gikaze gikoreshwa mu mishinga ikomeye n’ahantu h’ingenzi, ikizamini cyo gushiramo ubushyuhe gishobora gukorwa mbere.
Ikizamini cya Heat soak kizwi kandi nko kuvura abahuje ibitsina, bakunze kwita "guturika" .Ibirahuri byabonetse byitwaibirahuri bishyushye. Gushyushya ibizamini ni ugushyushyaikirahurekugeza kuri 290 ℃ ± 10 ℃ muri "itanura rya homogenizing", hanyuma ukayifata mugihe runaka, kugirango nikel sulfide (NiS) mu kirahure cyarangiritse byihuse irangiza icyiciro cya kirisiti kugirango yihutishe inzira yo kwaguka, kuburyo byakoreshejwe mbere nyuma yikirahure kirashobora guturika hakiri kare mu ruganda "itanura rya homogenizing", Gutyo rero kugabanya ikoreshwa ryikirahure cyashushe nyuma yo kwishyiriraho-guturika, umutekano wongerewe. Nyuma yikizamini cyo gushyushya ubushyuhe, igipimo cyo kwiyitirira ikirahure kirashobora kugabanuka kugera kuri kimwe muri 10,000, ariko ikizamini cyo gushiramo ubushyuhe ntigishobora kwemeza ko ikirahure cyashushe rwose kitabaho cyo kwiyahura, ariko kigabanya gusa kubaho kwiyahura. , kandi mubyukuri ikemura ikibazo cyo kwiyahura yibasiye impande zose mumushinga. Kubwibyo, ikizamini cyo gushyushya ubushyuhe nuburyo bwiza cyane bwo gukemura ikibazo cyo kwiyahura mu bihe bya tekiniki bigezweho bizwi ku isi yose.
Ibyiza byubushyuhe shyira ikirahure gikonje
Igipimo cyo kwiyitirira hasi: ukurikije imibare, igipimo cyo kwiyahura cyikirahure gifite ubushyuhe hamwe nogupima ubushyuhe ukurikije gahunda birashobora kugabanuka kuva kuri 0.3% bikagera kuri 0.01%, biri munsi cyane yikigereranyo cyo kwiyahura cyikirahure gisanzwe.
Umutekano mwinshinagabanya amafaranga yo kubungabunga no gusana nyuma: kubera umuvuduko muke wo kwiyahura, gabanya impanuka yatewe no kwiyahura kwikirahure kirakaze, kandi ugabanye cyane ikiguzi cyikirahure cyikirahure cyo guturika kugirango urinde neza ikirahure.
