Phapang lipakeng tsa lisebelisoa tsa refractory ramming le refractory castable

Phapano ke efe lipakeng tsa thepa ea ramming ea refractory le refractory castable? Pele ho tsohle, lihlahisoa tsena tse peli li khetholloa e le lisebelisoa tse sa tsitsang tse sa bopehang. Refractory ramming material ke mokhoa oa kaho o sebelisang ramming mme o thatafatsoa ke ho futhumatsa. Refractory castable ke mokhoa oa kaho oa ho tšela, o ka thatafatsang ntle le ho futhumatsa. Phapano ke efe lipakeng tsa thepa ea ramming ea refractory le refractory castable? Phapang e teng mokhoeng oa kaho le mokhoa oa ho thatafatsa. Ka kopo, sheba lintlha tse ka tlase.

Tlhaloso ea ramming le ho tšela

1. Thepa ea refractory ramming, e kopanyang lisebelisoa tsa ramming tse refractory setšeng, ka ho sebelisa pneumatic pick kapa ramming ea mochini, khatello ea moea ha e ka tlase ho 0.5MPa. Likarolo tse nang le thepa e fokolang kapa tse seng bohlokoa ho sebelisoa le tsona li ka koaheloa ka letsoho. E entsoe ka ho kopanya li-refractory aggregates, powders, binders, admixtures le metsi kapa lino tse ling tse nang le gradation e itseng. Ka hona, lesela la lisebelisoa tsa ramming le refractory le na le mongobo o fokolang, li-knots tse thata le ts’ebetso e ntle ho feta li-castable tse refractory le tse hanyetsanang tsa thepa e tšoanang. Mefokolo ea lisebelisoa tsa ramming tsa refractory ke lebelo le liehang la kaho le matla a phahameng a mosebetsi, ‘me ho na le tšekamelo ea ho nkeloa sebaka ke lisebelisoa tse omeletseng tse thothomelang le li-castable tsa boleng bo phahameng ba refractory.

2. Refractory castables. Refractory castables ka kakaretso e lahleloa, ea sisinyeha kapa ea tampuoa sebakeng sa ts’ebeliso, hape e ka etsoa li-preforms bakeng sa tšebeliso.

Kopo le lihlopha

Phapano ke efe lipakeng tsa lisebelisoa tsa refractory ramming le refractory castables? Li-castable tse refractory li na le metsi a mangata ‘me li sebelisoa haholo. Likarolo tse nang le lisebelisoa tsa ho raha tse sa tsitsang haholo kapa lisebelisoa tse sa reng letho li ka kopanngoa ka letsoho. Lisebelisoa tsa ramming tsa refractory li arotsoe ho latela lisebelisoa tse tala: alumina e phahameng, letsopa, magnesia, dolomite, zirconium le silicon carbide-carbon refractory ramming. Li-castable tsa refractory li arotsoe ho ea ka lisebelisoa tse tala: 1. Ho ea ka porosity, ho na le mefuta e ‘meli ea li-castable tse teteaneng tsa refractory le lisebelisoa tse thibelang mocheso oa mocheso tse nang le porosity e seng ka tlase ho 45%; 2. Ho ea ka binder, ho na le hydraulic bonding le lik’hemik’hale tsa lik’hemik’hale. , Condensation e kopane le refractory refractory castables.

Refractory castable ke refractory e se nang sebopeho e hlahisoang haholo le ho sebelisoa. E sebelisoa haholo ho aha mefuta eohle ea lithapo tsa sebōpi le meaho e meng. E sebelisoa haholo ho metallurgy, petroleum, lik’hemik’hale, lisebelisoa tsa mohaho, matla a motlakase, lisebelisoa tsa indasteri ea mechine le lisebelisoa tsa ho futhumatsa, le lihlahisoa tsa boleng bo phahameng li ka boela tsa sebelisoa bakeng sa libōpi tsa koetliso.

Refractory ramming material ke thepa e ngata e entsoeng ka silicon carbide, graphite, le anthracite ea motlakase ea calcined e le lisebelisoa tse tala, tse kopantsoeng le mefuta e fapaneng ea li-additives tsa phofo ea ultrafine, le samente e kopantsoeng kapa resin e kopantsoeng e le setlamo. E sebelisetsoa ho tlatsa lekhalo pakeng tsa lisebelisoa tsa ho futhumatsa sebōpi le masonry kapa filler bakeng sa lera la boemo ba masonry. Thepa e thibelang mollo e na le botsitso bo botle ba lik’hemik’hale, ho hanyetsa khoholeho, khanyetso ea abrasion, ho hanyetsa ho tsoa, ​​le ho hanyetsa mocheso. E sebelisoa haholo ho metallurgy, thepa ea mohaho, koetliso ea tšepe e se nang ferrous, indasteri ea lik’hemik’hale, mechine le mesebetsi e meng ea tlhahiso.
