Mu nganda zikora ubushyuhe bwinshi, imikorere y'ibikoresho birwanya ubushyuhe igena mu buryo butaziguye imikorere myiza y'umusaruro, umutekano, n'igenzura ry'ikiguzi.Ikoreshwa rya sima nkeya (LCC)Yagaragaye nk'igisubizo gihindura ibintu byose, kirangwa n'umubare muke wa calcium oxide (≤3%) n'inyongera nke ya sima (3%-8%), ibyo bikaba bitanga ubushobozi bwo kugabanya imbaraga ugereranije n'ibikoresho bisanzwe byo guteka. Irwanya ubushyuhe cyane, irwanya isuri, ndetse n'ubushyuhe bwinshi bituma iba ingenzi cyane mu nganda zitandukanye ku isi.
Inganda zikora ibyuma ni zo ziyungukiramo cyane sima nke, aho ikora neza mu duce dushyuha cyane. Ikoreshwa cyane mu bikoresho byo gutunganya ubushyuhe, ibikoresho byo gushyushya, n'ibikoresho byo kuzunguruka, ndetse n'ibikoresho by'amashanyarazi bitwikira ibyuma n'ibikoresho byo kuzunguruka. Ku bijyanye no gukora ibyuma, LCC itanga uburinzi bwizewe ku bikoresho byo kuzunguruka, ibikoresho byo kuzunguruka, n'ibikoresho byo kuzunguruka, irwanya ingese zituruka ku byuma bishongeshejwe n'ibyuma mu gihe ikomeza kuba nziza ku bushyuhe bugera kuri 1800°C. Mu byuma bidakoresha feri, ni byiza cyane ku bikoresho byo gufata aluminiyumu, ibikoresho byo koza imyenda, n'ibikoresho byo kuzunguruka, bitewe n'inyongera zigabanya kwinjira mu byuma bishongeshejwe.
Inganda za sima zishingira cyane ku gipimo gito cya sima kugira ngo zongere uburambe bw'ibikoresho by'ingenzi bishyuha. Ikunze gukoreshwa ku gikoresho cy'inyuma cya kilneye, igipfukisho cya wicket, n'inyuma ikonjesha y'amatanura ya sima, aho yihanganira ubushyuhe bukabije n'ibikoresho byo kwangirika, bigatuma igihe cyo gukoresha ibikoresho kirushaho kuba gito. Ubushyuhe bwayo buke n'ubucucike bwayo bwinshi birinda gutakaza ubushyuhe, bikongera ubushobozi bw'ingufu kandi bikagabanya igihe cyo kuyitunganya - ibintu by'ingenzi ku bakora sima bashaka kugabanya ikiguzi.
Uretse ikoranabuhanga ry’ibyuma na sima, sima nto ikoreshwa mu gutwika amashanyarazi ifite uruhare runini mu nganda zitunganya peteroli, ingufu, n’imyanda. Mu nganda zitunganya peteroli, ishyira ingufu mu byuma bigabanya ubushyuhe n’imiyoboro ikoresha ubushyuhe bwinshi, ikarwanya isuri n’ubushyuhe bwinshi. Mu gutanga amashanyarazi, ikoreshwa mu byumba bitwika amaboiler, imiyoboro, n’ibikoresho bitandukanya inkubi y’umuyaga, ikarinda ubushyuhe bwinshi n’ingufu z’imyanda. Ikora neza kandi mu byuma bitwika imyanda, aho irwanya ingese zituruka ku myuka y’imyanda ihumanya n’uduce tw’ivu.
Uburyo bworoshye bwo gukora ibintu bya castable ya sima nke burushaho kwiyongera bitewe n'uburyo bworoshye bwo kubaka. Iboneka nk'uburyo bwo guhindagurika cyangwa bwo kwikorera, ishobora gucukurwa, gusigwa, cyangwa gupomperwa aho iherereye, igahinduka mu buryo bugoye no mu bice bigoye kugerwaho nta kwangiza imikorere yayo. Ingufu zayo z'ubushyuhe bwinshi ziyongera iyo ubushyuhe buvuguruye, ikarenga intege nke z'ibikoresho bisanzwe bya castable bitakaza imbaraga kuri 800-1200℃.
Byaba ku mashyiga y’inganda akenewe cyane, ibyuma bishongeshejwe, cyangwa imiyoboro ikoresha ubushyuhe bwinshi, ikoreshwa mu gutwika sima nke itanga umusaruro uhoraho kandi urambye. Guhuza kwayo no kuramba, gukoresha ibintu byinshi, no gukoresha neza ingufu bituma iba igisubizo cyiza cyo kugabanya ubushyuhe ku nganda zigezweho zikoresha ubushyuhe bwinshi. Hitamo LCC kugira ngo ugabanye ikiguzi cyo kubungabunga, wongere umutekano mu mikorere, kandi ugere ku ntego zirambye zo gukora.
