Lintlha tse tharo tsa mocheso o phahameng oa creep of lisebelisoa tse refractory

Litekong tsa lisebelisoa tsa refractory, mocheso o phahameng oa mocheso ke e ‘ngoe ea matšoao a bohlokoa bakeng sa ho lekola ts’ebetso le boleng ba thepa ea refractory. Kamano pakeng tsa deformation le nako ea thepa ea refractory tlas’a mocheso o phahameng o sa khaotseng le mojaro o itseng ke mocheso o phahameng oa mocheso oa thepa. Ha thepa e kenngoa tlas’a mojaro o itseng o ka tlaase ho matla a eona a ho qetela mocheso o phahameng, deformation ea polasetiki e tla etsahala ka mokhoa o ke keng oa qojoa, ‘me deformation ea eona e tla eketseha butle-butle ha nako e ntse e feta, esita le ho senya thepa. Mofuta ona oa ts’ebetso ea creep ha ho pelaelo hore o bohlokoa haholo bakeng sa tšebeliso ea lisebelisoa tsa refractory, hobane lintlha tse tharo tsa thepa ea refractory li nkoa ka nako e le ‘ngoe bakeng sa thepa ea ho hanyetsa mocheso o phahameng: matla, mocheso le nako.

Ka lebaka la mekhoa e fapaneng ea meroalo e sebelisoang ho thepa ea refractory, e ka aroloa ka sekhahla sa khatello e phahameng ea mocheso, sekhahla sa mocheso o phahameng oa mocheso, sekhahla sa mocheso o phahameng oa mocheso le sekhahla sa mocheso o phahameng oa mocheso. Har’a tsona, hangata ho sebelisoa khatello e phahameng ea mocheso (e bitsoang compression creep). Fetola).

Compressive creep of refractory refractory e hlalosoa e le: isothermal deformation ea lihlahisoa tse tlas’a khatello ea maikutlo ha nako e ntse e ea.

Hangata khatello ke 0.2MPa, ‘me sampole e hlokeha ho ba silindara e nang le lesoba le bohareng, le bophara ba 50mm ± 0.5mm, bolelele ba 50mm ± 0.5mm, le lesoba le bohareng le bophara ba 12 ho isa ho 13mm, coaxial le moqomo.
