Apara khanyetso ea litene refractory

Litene tse refractory li sebelisoa haholo boenjiniere. Litene tse refractory li boetse li behoa ka sebōping. Litene tsa refractory ha lia lokela ho finyella litlhoko tsa ho hanyetsa mollo le ho hanyetsa mocheso o phahameng, empa hape li finyella litlhoko tsa ho apara ho hanyetsa.

Ho hanyetsa abrasion ea litene tse refractory ho amana le mocheso. Litene tse ling tsa refractory, joalo ka litene tse phahameng tsa alumina, hangata li nkuoa li le mocheso o phahameng, ‘me ka mocheso o itseng (joalo ka ka har’a marang-rang a ka tlase ho 700-900 ℃), khanyetso ea ho roala e tla ba tlase, ke hore, joalo ka mocheso oa phahama, litene tsa refractory Ho hanyetsa ho apara ho fokotseha ka ho eketseha ha modulus ea elasticity. Ha mocheso o eketseha ho ea ho modulus e phahameng ea elasticity, ho hanyetsa ho apara hoa eketseha ka ho fokotseha ha modulus ea elasticity. Mohlala, khanyetso ea abrasion ea litene tsa letsopa ho 1200 ~ 1350 ℃ e betere ho feta mocheso oa kamore. Ha thepa ea refractory e ka holimo ho 1400 ° C, ho hanyetsa ha eona ho tla fokotseha ho feta. Litene tse ling tse refractory, tse kang litene tsa chrome refractory, li eketsa ho hanyetsa ha mocheso o ntse o eketseha.

Ho hanyetsa abrasion ea litene tse refractory ho itšetlehile ka sebopeho le sebopeho sa litene tse refractory. Ha sebopeho sa litene tse refractory e le polycrystalline e teteaneng e entsoeng ka kristale e le ‘ngoe, ho hanyetsa ha eona ho itšetlehile haholo ka ho thatafala ha likristale tsa liminerale tsa thepa. Boima bo phahameng le khanyetso e phahameng ea ho apara. Ha likristale tsa diminerale li se li-isotropic, thepa e na le lijo-thollo tse ntle le ho hanyetsa ho apara ho phahameng. Ha thepa e entsoe ka lintho tse ngata, ho hanyetsa ha eona ho apara ho amana ka ho toba le bongata bo bongata kapa porosity ea thepa, hammoho le matla a ho kopanya pakeng tsa likarolo. Ka hona, khanyetso ea abrasion ea setene sa refractory e lekana le matla a eona a ho hatella mocheso oa kamore, ‘me litene tsa sintered refractory li na le khanyetso e ntle ea abrasion. Ho hlophisoa le ho roala ho hanyetsa ha setene sena ho tla ba molemo ho feta litene tse refractory!
