Amatafari arwanya ubushyuhe bwinshi yo mu itanura, amatanura

Zhelu, Uruganda rw'Amatafari ya Refractory mu Bushinwa. Amatafari ya Refractory ni ibikoresho bya refractory biva mu ibumba rya refractory cyangwa ibindi bikoresho fatizo bya refractory. Umuhondo werurutse cyangwa umukara. Bikoreshwa cyane cyane mu kubakaamatanura yo gushongesha, ishobora kwihanganira ubushyuhe bwinshi bwa1,580℃ -1,770℃.Byitwa kandi amatafari y'umuriro. Igikoresho gikonjesha gifite imiterere n'ingano runaka.

Dukurikije ibice bitandukanye by'amatafari arwanya ubushyuhe, ashobora kugabanywamo ibyiciro bitanu, ari byo: amatafari arwanya ubushyuhe ashingiye ku bwoko bwa silikoni na alumina, amatafari arwanya ubushyuhe ashingiye ku bwoko bwa alkaline, amatafari arwanya ubushyuhe ashingiye ku bwoko bwa karuboni, amatafari arwanya ubushyuhe ashingiye ku bwoko bwa zirconium, n'amatafari arwanya ubushyuhe akoresha ubushyuhe.

Itanura iryo ari ryo ryose ntiryubakwa n'ubwoko bumwe gusa bw'amatafari arwanya ubukana, rikenera uruvange rw'amatafari atandukanye arwanya ubukana.

(1) Amatafari ya silica yerekeza ku matafari arwanya aside arimo SiO2 irenga 93%, ari na yo moko y'ingenzi y'amatafari arwanya aside. Akoreshwa cyane cyane muamafuru ya coke y'amabuye, ariko nanone ku byuma binini n'ibindi bice bitwara imizigo by'amatanura ashyushye yaikirahure gitandukanye,ibumba, imashini zitunganya karuboni, naamatafari arwanya ubukanaIkoreshwa mu bikoresho bishyushyamunsi ya 600°Cnahamwe n'ihindagurika rikomeye ry'ubushyuhe.

(2)Amatafari y'ibumbaAmatafari y'ibumba agizwe ahanini na mullite (25% kugeza 50%), ikirahure (25% kugeza 60%), na cristobalite na quartz (kugeza 30%). Ubusanzwe, ibumba rikomeye rikoreshwa nk'ibikoresho fatizo, clinker irasukwa mbere hanyuma ikavangwa n'ibumba ryoroshye. Ikirahuri gito cy'amazi, sima, n'ibindi bikoresho bishobora kongerwamo kugira ngo hakorwe ibintu bitaratwikwa n'ibikoresho bitameze neza. Ni itafari rikunze gukoreshwa cyane muamatanura atwika, amashyiga ashyushye,amatanura ashyushya,boiler z'amashanyarazi,amatanura y'indimu,amatanura azunguruka,ibumba,n'amatanura akoresha amatafari arwanya ubushyuhe.
(3)Amatafari afite alumina nyinshi kandi adafite ingufu. Ibigize amabuye y'agaciro y'amatafari afite aluminiyumu nyinshi ni corundum, mullite, na phases z'ibirahuri. Ibikoresho fatizo ni aluminiyumu nyinshi na sillimanite naturel ore, kandi hari na corundum yavanze, aluminiyumu ya sintered, mullite y'ubukorikori, na clinker calcined hamwe na aluminiyumu n'ibumba mu bipimo bitandukanye. Bikorwa cyane hakoreshejwe uburyo bwo gusya. Ariko kandi ibicuruzwa birimo amatafari yavanze, amatafari yavanze, amatafari adatwitswe, n'amatafari yavanze adashushanyije. Amatafari yavanze ya aluminiyumu menshi akoreshwa cyane muriinganda z'ibyuma n'ibyuma, inganda z'ibyuma zidakoresha feri, n'izindi nganda.

(4)Amatafari arwanya Corundum, amatafari ya korundum yerekeza ku bwoko bw'amatafari adashobora gushonga afite AL2O3 ingana na 90% naho korundum ikaba igice cy'ingenzi, gishobora kugabanywamo ibice bibiri:amatafari ya corundum yakozwe mu buryo bwa sinterednaamatafari ya corundum avanze

(5)Amatafari yoroshye kandi akingira ubushyuhe akoresha alumina nyinshiNi itafari ririnda ubushyuhe rifite bauxite nk'ingano nyamukuru ya AL2O3 itari munsi ya 48%. Uburyo bwo gukora bukoresha uburyo bwa foam, kandi uburyo bwo kongeramo umuriro bushobora no gukoreshwa. Amatafari yoroheje arinda ubushyuhe ashobora gukoreshwa muyubaka ahantu hatagira ubushyuhe bwinshi n'ahantu hataba hari ibintu bishongeshejwe bikabije kandi bishyushye cyane.Iyo ihuye n'umuriro, ubushyuhe bw'ubuso bw'amatafari arwanya ubushyuhe menshi ya alumina ntibugomba kurenza dogere 1350. Amatafari arwanya ubushyuhe menshi ashoboragukora ku muriro mu buryo butaziguye kandi bifite imiterere yo kurwanya ubushyuhe bwinshi, imbaraga nyinshi, naingaruka nziza zo kuzigama ingufuBirakwiriye kuriigisenge cy'itanura rya pyrolysis, itanura rishyushye cyane, itanura rizunguruka rya keramike, itanura ry'amashanyarazi rya porcelain, naamatanura atandukanye yo kurwanya.

(6)Amatafari yoroheje akingira ubushyuhe mu ibumbani amatafari akingira ubushyuhe afite AL2O3 ingana na 30% kugeza 48% akozwe mu ibumba rirwanya ubushyuhe nk'ibikoresho by'ibanze. Uburyo bwo kuyikora bukoresha uburyo bwo gutwika hamwe n'uburyo bwo gufuro. Hakoreshejwe ibumba rirwanya ubushyuhe, amasaro areremba, n'ibumba rirwanya ubushyuhe nk'ibikoresho by'ibanze, hongerwamo umugozi n'umukungugu, binyuze mu kuvanga, gushushanya, kumisha, no gutwika, umusaruro ufite ubucucike buri hagati ya 0.3 na 1.5g/cm3 uraboneka.Umusaruro w'amatafari y'ibumba akingira ubushyuhe ugera kuri kimwe cya kabiri cy'umusaruro wose w'amatafari akingira ubushyuhe.

Imikoreshereze

Ikoreshwa cyane cyane mu itanura riturika, mu matanura ashyushye,amatanura ashyushya, amatanura y'icyuma, amatanura ya coke, amatanura ya karuboni, ifuru, sisitemu zo gutwika ifuru, amatanura ya sima, amatanura y'ibirahure, amatanura ya tunnel, amatanura azunguruka, n'amatanura y'imigozi n'andi matanura. Ibikoresho byo gutwikira amatanura n'ubushyuhe bikoreshwa cyane muriikoranabuhanga mu byuma, inganda z'ibinyabutabire, ibumba, guteka, karuboni, guterera, imashini, ingufu z'amashanyarazi, ibikoresho by'ubwubatsi, peteroli, n'izindi nganda.
