Ibyiciro bya bauxite
Bauxite, izwi kandi nka bauxite cyangwa bauxite, igizwe ahanini na oxyde ya aluminium kandi irimo umwanda. Bauxite ifite ibice bigoye cyane kandi ni ijambo rusange kubutare butandukanye bwa hydrous alumina ubutare bufite inkomoko zitandukanye.
Ukurikije ikoreshwa rya bauxite, igabanyijemo icyiciro cya metallurgjiya, icyiciro cya shimi, icyiciro cya retratori, urwego rwo gusya, urwego rwa sima, nibindi. Bauxite clinker ifite ibipimo bikwiye bya AL2O3 / Fe2O3 na AL2O3 / SiO2 ikoreshwa mugushonga alumina.
1. Ubushyuhe bwo hejuru cyane, ubushyuhe bukomeye bwumuriro, kandi nta gucika. Umucanga wa aluminium mullite nigicuruzwa gishingiye kuri aluminium-silicon. Nyuma yo kubara, guhinduka kwayo hamwe no guhindagurika kwubushyuhe bwumuriro birarenze kure cyane byumusenyi wa quartz ufite imiterere ya kristu igizwe na silikoni imwe ya kirisiti. Ntabwo byoroshye guhindurwa nicyuma cyamazi kugirango kibe gishonga gike, gishobora gutsinda umucanga wa Quartz gifite coeffisiyeti nini yo kwagura ubushyuhe hamwe numusaruro muke mugihe cya kondegene, bikavamo ibitagenda neza nko guta neza neza no kumusenyi.
2. Gutandukanya ibice bitandukanye, guhumeka neza. Umusenyi wubatswe nubutaka bwuruganda rwa Raymond hanyuma ukavangwa ukurikije igipimo cyihariye cyagabanijwe mugihe cyo kubyara kugirango umwuka wogusiga irangi. Byongeye kandi, ibicuruzwa bitunganyirizwa mu ruganda rwumupira, ibice byumucanga utunganywa ninganda za Raymond bigenzurwa neza, kandi igipimo cya clinker ya bauxite nubumenyi.
3. Ipitingi ifite fusion nyinshi, imbaraga nyinshi hamwe na demoulding byoroshye. Imyenda itandukanye yo kwifashisha ikoresha ibicuruzwa bya aluminium-silikoni, ibicuruzwa byabuze ifuro ya bauxite ifu nziza, ukurikije ibipimo bitandukanye biva imbere. Gukomatanya kuva kumeza kugeza kubisubizo bivamo urwego rwo hejuru rwo kwishyira hamwe hagati yimyenda; mugihe kongera imbaraga za coating hamwe no kurwanya isuri kugirango wirinde ibibazo nko gusenyuka, biroroshye kandi kumanuka. Kandi bauxite mullite nibikoresho bidafite aho bibogamiye, kandi clinker ya bauxite irashobora gukoreshwa nka acide na alkali binders.
