Ubwoko nibintu bifatika bya retratori zisanzwe

Igice cya corundum cyera

1 ref Kwanga ni iki?

Ibikoresho bivunagura muri rusange bivuga ibikoresho bidasanzwe bidafite ubutare hamwe n’umuriro urenga 1580 ℃.Harimo amabuye karemano nibicuruzwa bitandukanye bikozwe mubikorwa runaka ukurikije intego zimwe zisabwa.Ifite ubushyuhe bwo hejuru bwubukanishi hamwe nubunini bwiza butajegajega.Nibikoresho nkenerwa muburyo bwose bwibikoresho byo hejuru.Ifite uburyo butandukanye bwo gukoresha.

2 、 Ubwoko bwa retractories

1. Amashanyarazi acide mubisanzwe yerekeza kuri retro zifite SiO2 zirenga 93%.Ikintu nyamukuru kiranga ni uko ishobora kurwanya isuri ya acide ya acide ku bushyuhe bwinshi, ariko biroroshye kubyitwaramo na alkaline.Amatafari ya silika n'amatafari y'ibumba akunze gukoreshwa nka retratori ya aside.Amatafari ya Silica nigicuruzwa kirimo silike irenga 93% ya okiside ya silicon.Ibikoresho bibisi bikoreshwa birimo silika hamwe namatafari ya silika.Ifite imbaraga zo kurwanya isuri ya acide, umutwaro mwinshi woroshye ubushyuhe, kandi ntugabanuka cyangwa ngo waguke gato nyuma yo kubara inshuro nyinshi;Nyamara, biroroshye kurandurwa nigishishwa cya alkaline kandi gifite imbaraga zo kurwanya ubushyuhe bwumuriro.Amatafari ya Silica akoreshwa cyane cyane mu ziko rya kokiya, itanura ry ibirahure, itanura rya acide nibindi bikoresho byubushyuhe.Amatafari y'ibumba afata ibumba ryangiritse nkibikoresho nyamukuru kandi birimo 30% ~ 46% alumina.Nibisubirwamo acide nkeya hamwe nibyiza birwanya ubushyuhe bwumuriro hamwe no kwangirika kwangirika kwa acide.Irakoreshwa cyane.

2. Uruganda rwa alkaline rusanzwe ruvuga ibyangiritse hamwe na oxyde ya magnesium cyangwa oxyde ya magnesium na calcium oxyde nkibice byingenzi.Izi nganda zifite ubukana bwinshi kandi zirwanya imbaraga za alkaline.Kurugero, amatafari ya magnesia, amatafari ya chrome ya magneya, amatafari ya chrome magnesia, amatafari ya aluminiyumu ya magnesia, amatafari ya dolomite, amatafari ya forsterite, nibindi bikoreshwa cyane cyane mu itanura rikora ibyuma bya alkaline, itanura ridafite fer fer hamwe n’itanura rya sima.

3. Ibikoresho bya aluminium silikate bivuga inganda hamwe na SiO2-Al2O3 nkibice byingenzi.Ukurikije ibirimo Al2O3, barashobora kugabanywamo igice cya silice (Al2O3 15 ~ 30%), ibumba (Al2O3 30 ~ 48%) na alumina ndende (Al2O3 irenga 48%).

4. Gushonga no guta ibintu bivuga ibicuruzwa bivunagura bifite ishusho runaka nyuma yo gushonga icyiciro mubushyuhe bwinshi hakoreshejwe uburyo runaka.

5Bamwe bavuga kandi ko inganda za alumina ziri hejuru kuri iki cyiciro.

6. Inganda zidasanzwe ni ibikoresho bishya bidafite ingufu zidasanzwe byakozwe hifashishijwe ibumba gakondo nububiko rusange.

7. Amorphous retractory ni uruvange rugizwe ninganda zivunagura, ifu, binder cyangwa izindi mvange mugice runaka, zishobora gukoreshwa muburyo butaziguye cyangwa nyuma yo gutegura amazi meza.Kuvunika bidafite ishusho ni ubwoko bushya bwo kuvunika nta kubara, kandi kurwanya umuriro ntabwo biri munsi ya 1580 ℃.

3 、 Ni ubuhe buryo bukoreshwa kenshi?

Inganda zisanzwe zikoreshwa zirimo amatafari ya silika, amatafari ya silika igice, amatafari y ibumba, amatafari maremare ya alumina, amatafari ya magnesia, nibindi.

Ibikoresho bidasanzwe bikunze gukoreshwa birimo amatafari ya AZS, amatafari ya corundum, amatafari ya chromium ya magnesium, amatafari ya karubide ya silicon, silicon nitride ihujwe na silicon karbide amatafari, nitride, siliside, sulfide, boride, karbide nizindi nganda zidafite ingufu za okiside;Kalisiyumu, okiside ya chromium, alumina, oxyde ya magnesium, okiside ya beryllium nibindi bikoresho bivunika.

Ibikoresho bikoreshwa cyane mubushuhe hamwe nibikoresho bivunika harimo ibicuruzwa bya diatomite, ibicuruzwa bya asibesitosi, ikibaho cyumuriro, nibindi.

Ibikoresho bikoreshwa cyane bya amorphous birimo ibikoresho byo gusana itanura, ibikoresho byo gukongeza umuriro, ibikoresho birwanya umuriro, plastiki zidashobora kuzimya umuriro, ibyondo birinda umuriro, ibikoresho byo kurasa umuriro, ibisasu birinda umuriro, ibishishwa birinda umuriro, gutwika umuriro, umuriro woroshye -ibikoresho bidashobora kwihanganira, icyondo cyimbunda, ububiko bwa ceramic, nibindi

4 、 Ni ubuhe buryo bufatika bwo kuvunika?

Imiterere yumubiri yinganda zirimo imiterere, imiterere yubushyuhe, ibikoresho bya mashini, imitungo ya serivise nibikorwa.

Imiterere yimiterere yinganda zirimo ubukana, ubwinshi bwubwinshi, kwinjiza amazi, umwuka mwiza, gukwirakwiza ingano ya pore, nibindi.

Imiterere yubushyuhe bwa reta zirimo ubushyuhe bwumuriro, coefficente yo kwagura ubushyuhe, ubushyuhe bwihariye, ubushobozi bwubushyuhe, ubushyuhe bwumuriro, emissivite yumuriro, nibindi.

Ibikoresho byubukorikori birimo imbaraga zo kwikuramo imbaraga, imbaraga zingutu, imbaraga zidasanzwe, imbaraga za torsional, imbaraga zogosha, imbaraga zingaruka, kwambara kwangirika, kunyerera, imbaraga zububiko, modulus ya elastique, nibindi.

Imikorere ya serivise yinganda zirimo kurwanya umuriro, koroshya ubushyuhe bwumuriro, guhindura umurongo wongeye gushyuha, kurwanya ubushyuhe bwumuriro, kurwanya slag, kurwanya aside, kurwanya alkali, kurwanya hydration, kurwanya isuri, kurwanya isukari, kurwanya okiside, nibindi.

Imikorere yibikoresho byangiritse birimo guhuzagurika, gusinzira, gutemba, plastike, guhuriza hamwe, kwihangana, gukomera, gukomera, nibindi.
