Igiciro Gihendutse Cyane Cyane Cya Aluminium Mullite Ishobora Gucukurwa
Kugira ngo ubashe kuguha ihumure no kwagura ikigo cyacu, dufite kandi abagenzuzi muri QC Workforce kandi tukwizeza serivisi nziza n'ibicuruzwa byacu kuriIbikoresho bidafite ishusho n'ibikoreshwa mu gukurura, Ibikoresho byatsindiye icyemezo cy’igihugu cy’ubuhanga kandi byakiriwe neza mu nganda zacu nkuru. Itsinda ryacu ry’abahanga mu by’ubwubatsi akenshi riba ryiteguye kugukorera inama no kugusubiza. Dushobora kandi kuguha ingero ku buntu kugira ngo duhuze n’ibyo wifuza. Hazakorwa ibishoboka byose kugira ngo tuguhe serivisi nziza n’ibisubizo. Niba koko ushishikajwe n’ikigo cyacu n’ibisubizo byacu, twandikire utwoherereza amabaruwa cyangwa uduhamagare ako kanya. Kugira ngo umenye ibisubizo byacu n’ikigo cyacu. Birenzeho, uzashobora kuza ku ruganda rwacu kugira ngo ubyirebere. Tuzahora twakira abashyitsi baturutse impande zose z’isi baza ku kigo cyacu. Tuzahora duha ikaze abashyitsi baturutse impande zose z’isi baza ku kigo cyacu. Tuzahuzwa no kubaka ikigo cyacu. Tuzavugana natwe ku bw’imikoranire. Twizera ko tuzasangira ubunararibonye bwiza mu bucuruzi n’abacuruzi bacu bose.
Ibikoresho byo gukanda birekuyeni ibintu bivanze mbere bigizwe n'ibice bito bito bito bito, ifu nziza, ibikoresho by'umwuga byo gufunga, n'ibindi bikoresho by'ubuhanga. Iyo hongewemo amazi cyangwa ibinyobwa byihariye, bishobora gukorwa byoroshye binyuze mu gusuka, gutigita, cyangwa guterura, kandi bishobora no gukorwamo ibice byihariye byateguwe kugira ngo bihuze n'inyubako zikomeye z'itanura. Iyo bimaze kuvugururwa, bikora imiterere y'urukuta rudafite umugozi irusha amatafari asanzwe akoreshwa mu gufunga no mu kubika ubushyuhe.
Byahoze bizwi nkabeto irwanya ubukanaKubera imiterere yayo, uburyo bwo kuyishyiraho, n'uburyo bwo kuyikora bisa na sima y'ubwubatsi, ibikoresho byacu bya refractory castable byavuguruwe hakoreshejwe formula zigezweho kugira ngo bitange umusaruro mwiza mu nganda zikomeye.
Gushyira mu byiciro ibicuruzwa
Dutanga ubwoko bwose bw'ibikoresho bidashobora guhindurwa kugira ngo bihuze n'ibikenewe mu nganda, bishyizwe mu byiciro hakurikijwe ibikoresho, uburyo bwo gukurura, n'imikorere:
1. Bikurikije Ibikoresho:Ibikoresho binini bya alumina, ibikoresho binini bya alumina-magnesia, ibikoresho binini bya alumina-silicon carbide-carbon, ibikoresho binini bya aside, ibikoresho binini bya alkali, ibikoresho binini byabugenewe byoroshye, nibindi.
2. Binyuze kuri Binder:Ibikoresho bya sima bifatanye na kalisiyumu na sima, ibikoresho bya sima bidafite calcium, ibikoresho bya fosfeti bifatanye, ibikoresho bya silica sol bifatanye na sima, nibindi (ibikoresho bya sima bidafite calcium na kalisiyumu bifite porosity nke kandi bifite imbaraga nyinshi za mekanike).
3. Binyuze mu mikorere:Ibikoresho byo mu bwoko bwa castable byigenga, ibikoresho byo mu bwoko bwa castable byuma vuba, ibikoresho byo mu bwoko bwa castable bidashira, ibikoresho byo mu bwoko bwa castable bidashyuha, ibikoresho byo mu bwoko bwa castable bikingira ubushyuhe, ibikoresho byo mu bwoko bwa castable bikingira ubushyuhe, nibindi.
Ibyiza by'ingenzi:
1. Ubudahangarwa budasanzwe ku bushyuhe bwinshi:Ishobora kwihanganira ubushyuhe bugera kuri 1600-1800°C, igakomeza imiterere yayo idasenyuka cyangwa ngo itakaze imitungo yayo ndetse no mu nganda zishyushye nko gushonga kw'ibyuma no gukora ibirahuri.
2. Kuramba cyane no kurwanya ingese:Irwanya kwangirika, isuri yashongeshejwe, ndetse n’ibitero bya shimi, bigabanya ikiguzi cyo gusimbuza no kubungabunga kenshi, kandi bikongera igihe cyo gukora cyane ku miyoboro yawe y’itanura.
3. Guhagarara neza mu gihe cy'ihindagurika ry'ubushyuhe:Ishobora kwihanganira ihindagurika ry’ubushyuhe ritunguranye idacitse cyangwa ngo igabanuke, bigatuma iba nziza ku bikoresho bifite akazi kenshi ko guhagarara, nk'amatanura azunguruka n'ibikombe by'icyuma.
4. Ubwubatsi bworoshye no guhindura ibintu uko bishakiye:Bikwiriye gukoreshwa mu gushushanya imiterere igoye n'imiterere y'ibipimo, bigahuza n'imiterere itandukanye y'itanura; tunatanga ibice byihariye byateguwe mbere y'uko bishyirwaho ndetse n'uburyo bwo guhindura formula bitewe n'imiterere y'akazi kawe (ubushyuhe, uburemere bw'ibikoresho, ubwoko bwa corruption).
5. Gukoresha neza ingufu no kuzikoresha neza:Ubushobozi bwiza bwo gukingira ubushyuhe bugabanya igihombo cy'ubushyuhe, bigabanya ikoreshwa ry'ingufu mu kubungabunga ubushyuhe; inzira yoroshye yo kubaka irushaho kunoza imikorere y'inyubako kandi igabanya ikiguzi cy'abakozi; hari uburyo bwo kongera gukoreshwa mu gutunganya ibintu mu buryo burambye.
6. Gukomera cyane (Ntabwo ari ngombwa):Kongeramo insinga z'icyuma kidashonga birushaho kunoza ubukomere bw'imashini ku bice bifite imbaraga nyinshi za mashini; kongeramo insinga zidafite umwimerere byongera ubukomere n'ubushyuhe bwo kwirinda ubushyuhe bw'ibikoresho bidashobora gushyuha.
