Uburemere bworoshye Silica Amatafari 1.0

Amatafari ya silika yoroheje akoresha silika yajanjaguwe neza nkibikoresho fatizo, kandi ubunini bwayo bukomeye ntibusanzwe burenze 1mm, naho ibice bitarenze 0.5mm ntibiri munsi ya 90%. Ibintu byaka umuriro byongewe kubibigize cyangwa uburyo bwo kubyara gaze bukoreshwa muburyo bubi, hanyuma bukarasa. Irashobora kandi gukorwa mubicuruzwa bidakorewe. Ikoreshwa cyane cyane mubice bitandukanye byitanura bisaba kwigizayo cyangwa kugabanya ibiro nta guhuza neza na gushonga, nta ngaruka za gaze zangirika, kandi nta mpinduka zubushyuhe zitunguranye. Ikoreshwa mubushyuhe bwinshi kandi ntishobora guhura nibikoresho bya alkaline. Ukurikije ibikoresho, ubushyuhe bwabwo bukoreshwa buri hagati ya 1200 na 1550 ℃.

Amatafari ya silika yoroheje ni ibikoresho bidasanzwe, bikoreshwa cyane cyane mubirahure ninganda zibyuma. Mubihe byinshi, amatafari ya silika yoroheje n'amatafari ya silika yuzuye akoreshwa nkibice byubatswe. Bikunze gukoreshwa mu nganda zikozwe mu kirahure, cyane cyane mu kubika itanura, bityo kugabanya ubushyuhe no kongera imikorere yo gushonga. Mu nganda zikora ibyuma, amatafari ya silika yoroheje akoreshwa muburemere bwurukuta rwamashyiga ashyushye hamwe na domes.

1. Amatafari ya silika yoroheje akoreshwa mu nganda zikirahure - kubika ubushyuhe bwamashyiga yububiko

Muburyo bwo gushonga ibirahure, ubushyuhe bwo hejuru bugerwaho mugice cyo hejuru cyo hejuru. Ukurikije ubwoko bw'ikirahure, ubushyuhe buri hafi 1600 ° C. Igice cyoroheje gisanzwe cyakozwe nkibice bibiri cyangwa byinshi.

Amatafari yoroheje ya silika ahura cyane nubushyuhe bwubushyuhe. Biteganijwe ko urwego rumwe rwububiko (imiterere nuburemere bworoshye) rufite ibintu bimwe cyangwa bisa byo kwaguka. Amatafari ya silika afite ubwinshi bwa 1250kg · m-3 cyangwa 1000kg · m-3 arashobora kuzuza ibisabwa murwego rwinshi. Igice gikurikira gikoresha amatafari ya silika afite ubwinshi bwa 800Kg · m-3 cyangwa 600kg · m-3.

Amatafari yoroheje ya silika arashobora guhunikwa kububiko bwitanura cyangwa kubumba ibumba ryumuriro wa silika. Nta mutwaro wa chimique mugihe cya serivisi yumuriro (imyaka myinshi). Amatafari ya silika yoroheje akoreshwa cyane cyane kubera ko imiti nubumara bigize urwego rukora bisa nubwa matafari ya silika yuzuye yakoreshejwe.

2. Amatafari ya silika yoroheje akoreshwa munganda zibyuma - itanura rishyushye

Amatanura ashyushye akoreshwa kenshi mumyuka ishyushye (bita blast furnace blast), ifitanye isano numuyaga usohora w'itanura. Ukurikije imiterere n’aho itanura rishyushye, ubushyuhe buri hagati ya 1000 na 1300 ° C, naho umwuka ushyushye uri hagati ya 2300 na 6500 m3 · min-1.

Ibi bisaba kubara ikigereranyo kiri hagati yitanura rishyushye (ingano yibice bitandukanye hamwe n’ahantu hakoreshwa) hamwe n’ikirahuri cy’ibirahure ku nzego zitandukanye n'imitwaro itandukanye, byibanda ku miterere ya thermomechanical. Kubice byoroheje, ubwinshi bwijwi bwakoreshejwe ni 1250kg · m-3 cyangwa 1050kg · m-3 (bitewe ahanini nimbaraga zabo zo hejuru)
