Ibikoresho byo mu bwoko bwa Refractory bya Sima Rotary Tan

Ibikoresho byo mu bwoko bwa Refractory bya Sima Rotary Tan

1. Ibikoresho by'icyuma bikonjeshwa n'imigozi bikoreshwa mu itanura rya sima
Ibikoresho bikonjeshwa n'ibyuma byinjiza imigozi y'icyuma idashyuha mu gikoresho, bityo ibyo bikoresho bikagira imbaraga nyinshi kandi birwanya ubushyuhe, bityo byongera imbaraga zo kwangirika no kumara igihe kirekire. Ibikoresho bikoreshwa cyane cyane mu bice bishyuha cyane nko mu ifuru, mu kanwa ko kugaburira, mu kabari kadashira n'icyuma gishyushya amashanyarazi.

2. Ibikoresho byo gutwika bitara sima bifite sima nkeya byo gukoresha mu itanura rya sima
Ibikoresho bito birwanya sima cyane cyane birimo ibinini bya alumina, mullite na corundum birwanya corundum. Uru ruhererekane rw'ibicuruzwa rufite imiterere yo gukomera cyane, kurwanya gukaraba, kudashira no gukora neza cyane. Muri icyo gihe, ibikoresho bishobora gukorwamo ibinini birwanya guturika vuba hakurikijwe igihe umukoresha akenera mu guteka.

3. Ibikoresho bikomeye birwanya alkali byo mu itanura rya sima
Ibikoresho binini birwanya alkali kandi birwanya isuri bitewe n’imyuka ya alkali n’ibisigazwa by’amazi, kandi bimara igihe kirekire. Ibi bikoresho bikoreshwa cyane cyane mu gutwikira inzugi z’itanura, mu matanura ashaje, mu buryo bwo gushyushya, mu buryo bwo gucunga, nibindi n’ibindi bikoresho by’inganda.

Uburyo bwo kubaka ibikoresho byo mu itanura rizunguruka bifite aluminiyumu nkeya bishobora gucukurwamo sima nyinshi
Kubaka ibikoresho byo gutwika bya aluminiyumu ifite sima nkeya cyane byo gushyira mu itanura rizunguruka bisaba kwitabwaho cyane cyane mu buryo butanu bukurikira:

1. Kugena aho ingingo zo kwaguka zihurira
Hashingiwe ku bunararibonye bwa mbere bwo gukoresha ibikoresho byo mu ifuru bifite aluminiyumu nyinshi kandi bifite sima nke, ibikoresho byo kwagura ni ikintu cy'ingenzi bigira ingaruka ku buzima bw'ibikoresho byo mu ifuru bifite sima izunguruka. Ibikoresho byo kwagura mu gihe cyo gusukura ibikoresho byo mu ifuru bizunguruka bigenwa ku buryo bukurikira:

(1) Impande zizunguruka: ibice bya metero 5, fibre ya aluminiyumu ya 20mm ifatanye hagati y’ibikoresho bya castable, kandi fibre ziratsindagirwa nyuma yo kwaguka kugira ngo zihagarike uburemere bwo kwaguka.

(2) Imirongo igororotse: Buri mirongo itatu y'icyuma gikoreshwa mu gushushanya ishyirwamo plywood ya 100mm yimbitse mu cyerekezo cy'imbere, hanyuma hagasigara igice ku mpera y'akazi, ku mirongo 6 yose hamwe.

(3) Mu gihe cyo gusuka, hakoreshwa imiyoboro 25 yo gusohora amazi kuri metero kare imwe kugira ngo harekurwe ingano runaka y'umuvuduko mu gihe cyo gukoresha umuriro mu itanura.

2. Kumenya ubushyuhe bw'inyubako
Ubushyuhe bukwiye bw'ibikoresho byo mu bwoko bwa aluminium ifite sima nkeya ni 10 ~ 30°C. Niba ubushyuhe bw'ikirere buri hasi, ingamba zikurikira zigomba gufatwa:

(1) Funga ibidukikije bikikije inyubako, ongeramo ibikoresho byo gushyushya, kandi wirinde ko ubukonje bukonje cyane.

(2) Koresha amazi ashyushye kuri 35-50°C (biterwa n'ingufu zo gusukura aho hantu) kugira ngo uvange ibikoresho.

3. Kuvanga
Menya ingano y'imvange icyarimwe ukurikije ubushobozi bw'imvange. Nyuma yo kumenya ingano y'imvange, shyiramo ibikoresho byo gusuka mu gikapu n'inyongera nto ziri mu gikapu mu mvange icyarimwe. Banza utangire imvange yumuke mu minota 2-3, hanyuma wongeremo 4/5 by'amazi yapimwe mbere, uvange iminota 2-3, hanyuma umenye 1/5 cy'amazi asigaye ukurikije ubukana bw'icyondo. Nyuma yo kuvanga neza, hakorwa igerageza ryo gusukura, hanyuma ingano y'amazi yongewemo igenwa hamwe n'imiterere y'imvange n'imvange. Nyuma yo kumenya ingano y'amazi yongewemo, igomba kugenzurwa cyane. Mu gihe ugenzura ko imvange ishobora kunyeganyezwa, hagomba kongerwamo amazi make ashoboka (ingano y'amazi yongewemo kuri iki gikoresho ni 5.5%-6.2%).

4. Ubwubatsi
Igihe cyo kubaka icyuma gikoreshwa mu gucukura gikozwe muri aluminiyumu nkeya ni iminota 30. Ibikoresho byakuwemo amazi cyangwa bifunze ntibishobora kuvangwa n'amazi kandi bigomba gutabwa. Koresha inkoni icukura kugira ngo uhuze neza kugira ngo uhuze neza. Inkoni icukura igomba kubikwa kugira ngo wirinde ko inkoni isigaye ikora iyo inkoni icukura idakora neza.
Kubaka ibikoresho bishobora gucukurwa bigomba gukorwa mu duce duto dukikije itanura rizunguruka. Mbere yo gusukura agace kose, ubuso bw'aho bwubakwa bugomba gusukurwa kandi nta mukungugu, ifu yo gusudira n'indi myanda bigomba gusigara. Muri icyo gihe, reba niba gusudira irangi ry'inkingi n'irangi rya asphalt biriho. Bitabaye ibyo, hagomba gufatwa ingamba zo kubikosora.
Mu kubaka umurongo, imiterere y'igice cyo gucukura igomba gusukwa ku mugaragaro kuva ku murizo w'itanura kugeza ku mutwe w'itanura uri hepfo y'igice cyo gucukura. Inkunga y'icyitegererezo igomba gukorwa hagati y'icyuma gifunga n'icyuma. Icyuma gifunga n'icyuma gifunga bifatanye neza n'ibiti. Uburebure bw'icyuma gifunga ni mm 220, ubugari ni mm 620, uburebure ni m 4-5, kandi inguni yo hagati ni 22.5°.
Kubaka igice cya kabiri cy’icyuma gishongeshwa bigomba gukorwa nyuma yuko igice gishongeshejwe kandi ifuro rigakurwaho. Ku ruhande rumwe, icyitegererezo gifite ishusho nk'iy'uruziga gikoreshwa mu gufunga igishongeshwa kuva ku mutwe w'itanura kugeza ku murizo w'itanura. Ibisigaye birasa.
Iyo ibikoresho byo gucukura binyeganyega, icyondo kivanze kigomba gushyirwa mu ibumba ry'ipine mu gihe kirimo gunyeganyega. Igihe cyo gunyeganyega kigomba kugenzurwa kugira ngo hatabaho uduheri tugaragara ku buso bw'umubiri w'icyuma gicukura. Igihe cyo gucukura kigomba kugenwa n'ubushyuhe bw'aho bubaka. Ni ngombwa kwemeza ko gucukura bikorwa nyuma yuko ibikoresho byo gucukura bishyizwe neza kandi bifite imbaraga runaka.

5. Guteka igitambaro cyo mu gitambaro
Ubwiza bw'urupapuro rwo guteka mu itanura rizunguruka bugira ingaruka ku buzima bw'urupapuro. Mu gihe cyo guteka mbere, bitewe n'uburambe buke n'uburyo bwiza, uburyo bwo gutera amavuta akomeye yo gutwika bwakoreshejwe mu gihe cyo guteka mu bushyuhe buke, ubushyuhe buri hagati n'ubushyuhe bwinshi. Ubushyuhe bwari bugoye kugenzura: iyo ubushyuhe bugomba kugenzurwa munsi ya 150°C, amavuta akomeye ntabwo byoroshye kuyatwika; iyo ubushyuhe buri hejuru ya 150°C, umuvuduko wo gushyushya uba wihuta cyane, kandi ubushyuhe mu itanura burangana cyane. Ubushyuhe bw'urupapuro aho amavuta akomeye atwikwa buri hejuru ya 350~500°C, mu gihe ubushyuhe bw'ibindi bice buba buri hasi. Muri ubu buryo, urupapuro rworoshye guturika (urupapuro rwometseho rwaturitse mu gihe cyo guteka), bigira ingaruka ku buzima bw'urupapuro.
