marble ikirahuri cyumupira igikinisho kirahure umupira wimbere mubukorikori bwubukorikori mini bukonje
Ibikoresho fatizo byumupira wikirahure ahanini ni imyanda yikirahure nibikoresho fatizo. Gukora ibirahuri, mbere ya byose, ubwoko bwose bwamabuye y'agaciro agomba guhonyorwa, akongerwamo ifu, hanyuma akurikije ibice byikirahure, bikozwe mubikoresho bivanze, hanyuma akakaraba hamwe nikirahure cyimyanda mumatara yikirahure kugirango ashonge, akore ibirahuri. Ikirahuri cyamazi gitembera mu kigega cyo kugaburira kandi kigomba gushonga neza no gusobanurwa. Igikorwa cyo gusobanura nicyiciro cyubushyuhe bwo hejuru murwego rwo gushonga ibirahure (1400-1500 ℃), ishingiro ryibikorwa byo gusobanura ni ukuzamura ubushyuhe no kugabanya ubukonje no guhuza ibikorwa bisobanutse, kuruhande rumwe kugabanya ububobere buoyancy resistance, kuruhande rumwe kugirango yagure ububobere, gukuramo ibibyimba, no guca inkomoko yibishobora kuvugururwa. Nyuma yo gusobanurwa, amazi yikirahure amaherezo asohoka hanze kugirango akore ububiko. Ubushyuhe bwububiko, ikirahuri cyamata muri rusange 1150 ~ 1170 ℃, ikirahuri gisanzwe kibonerana ni 1200 ~ 1220 ℃. Ububiko bukozwe muri pellet inshuro 200 kumunota. Urusoro rw'umupira runyura muri chute, umugabuzi wumupira, hanyuma akimurwa nisahani yo gukwirakwiza umupira, akazunguruka muri feri zitandukanye, hanyuma akagwa mumupira ugizwe na groove igizwe nizingo eshatu zifite icyerekezo kimwe cyo kuzunguruka. Urusoro rw'umupira ruzunguruka kuri roller kandi hejuru yubushyuhe bwo hejuru burakora, buhoro buhoro bikora umupira wikirahure cyoroshye kandi kizengurutse.
