Ibisobanuro bya sima yo hasi Ibisobanuro
Amabuye ya sima make ni ubwoko bumwe bwo kuvunika hamwe nubushyuhe bwo hejuru bwa serivisi irenga 1550 ℃, ikoresha sima ya aluminiyumu nkumuhuza, aho CaO iri munsi ya 2,5%. Amashanyarazi make ya sima yamashanyarazi agizwe ahanini agizwe ninganda zangiritse, ifu yamazi namazi. Ugereranije na gakondo ya retractory castable, sima nkeya yamashanyarazi ifite urukurikirane rwimikorere myiza nka sima nkeya, porotike nkeya, ubwinshi bwamajwi hamwe nubukonje bukabije bwo gukiza-imbaraga. Kandi nanone sima nkeya yubucucike buri hejuru kurenza izindi zangirika.
Ibyiza bya sima yo hasi
- Amazi make.
- Kwanga cyane,
- Imbaraga nyinshi.
- Igipimo gito cyo guhindura umurongo.
- Ubushyuhe bwo hejuru.
- Ubukonje buke nubucucike bwinshi.
- Ubushyuhe bwo hejuru hamwe no kurwanya slag.
Uburyo bwo gukora bwa sima yo hasi
Isima yo hasi ya cement isubirwamo ikozwe mu ifu ya ultrafine, sima ya alumine hamwe nibindi bivangwa. Byongeye kandi, ingano yibi bintu byose irashobora guhindura imikorere yayo. Kubijyanye n’amazi yacyo, ukurikije ubwishingizi bworoshye bwo kuvanga ibikoresho, kongeramo amazi make birashobora kugabanya ububobere no kongera imbaraga. Amashanyarazi make ya sima yamashanyarazi afite ibyiza byamazi make, ubucucike bwinshi nimbaraga nyinshi, niyo mpanvu ibyo bikoresho bivunika bikoreshwa cyane mumirima myinshi hamwe n’itanura ritandukanye n’itanura.
Ibyiza bya sima yo hasi
Ubushyuhe Bwinshi Ubushyuhe n'imbaraga hamwe na Anti - Kurwanya ruswa.
Ubucucike buke nubucucike bwinshi. Mugihe cyubwubatsi, 1/3 ~ 1/2 gusa cyamazi yamazi gakondo azongerwamo.
Kongera Imbaraga hamwe no Kuzamura Ubushyuhe bwo Kuvura Ubushyuhe Nyuma yo Gutera Mubishusho: Hamwe noguhindura neza ingano yubunini, birashobora kuvangwa mukwiyitirira ubwikorezi no kuvoma ibintu bisuka.

Ikoreshwa rya sima nkeya
Isima nkeya ya sima ikoreshwa cyane mu nganda nyinshi nk'inganda zikora metallurgjiya, inganda za peteroli, uruganda rw'amashanyarazi, inganda zubaka n'izindi nganda. Kandi na sima yo hasi ya sima irashobora gukoreshwa kumatanura no guteka ahantu hatandukanye ukurikije ibice bitandukanye. Kurugero, ibumba hamwe na alumina ndende ya sima yamashanyarazi irashobora gukoreshwa byombi kumurongo witanura ryubushyuhe, itanura ryokongejwe hamwe nandi matanura yo kuvura ubushyuhe.
Uruganda ruto rwa sima rushobora kuva mu ruganda rwa RS
Uruganda rwa RS ni uruganda rukora sima rwumwuga rutanga isoko rwashinzwe mu ntangiriro ya 90 yikinyejana cya makumyabiri. Uruganda rwa RS rugizwe ninzobere muri sima nkeya mumyaka irenga 20. niba ufite ibyo ukeneye bya sima ikarishye, cyangwa ufite ibibazo bimwe na bimwe bya sima ntoya yangiritse kubyerekeranye numubiri nubumara, nyamuneka twandikire kubuntu. n'amafaranga y'uruganda rukora inganda nkumwuga wo hasi wa sima wabigize umwuga wo gukora china, ufite ibyiza byo guhatanira gutya:
- Igiciro cyo Kurushanwa: Kora ibicuruzwa birushanwe kumasoko yawe,
- Ubunararibonye Bwinshi: Irinde gucamo no kugoreka amatafari,
- Ibishushanyo bitandukanye: Bika amafaranga yububiko kuri wewe,
- Igenzura rikomeye: Kuzuza ubuziranenge bwabakiriya,
- Ibigega binini: Kwemeza gutanga vuba,
- Gupakira umwuga: Irinde kwangirika no kurinda ibicuruzwa mu bwikorezi.
