Ke lintlha life tse amang ho hanyetsa ha litene tsa refractory?

Litene tse refractory li ‘nile tsa sebelisoa haholo mererong e mengata. Litene tse refractory li boetse li behiloe ka sebōping sa sekoti. Litene tsa refractory ha lia lokela ho finyella feela litlhoko tsa ho hanyetsa mollo le ho hanyetsa mocheso o phahameng, empa hape li finyella litlhoko tsa ho apara ho hanyetsa.

Ho hanyetsa ho roala ha litene tsa 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 mekhahlelo e mengata, 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. Sebopeho, sebopeho, mocheso, joalo-joalo oa setene sa refractory se tla ama ho hanyetsa ha sona, ho etsa hore setene sa refractory se be se setle haholo ho hanyetsa ho apara!

Ho hanyetsa ho roala ha litene tsa refractory ho boetse ho amana le mocheso. Ka mohlala, mocheso oa mocheso o ka tlase ho 900 ° C, ka kakaretso ho nkoa hore litene tse refractory li na le tekanyo e itseng ea ho hanyetsa ho apara (e kang ka tlase ho 900 ° C). Ho ka nkoa hore ha mocheso o ntse o eketseha, ho hanyetsa ho apara ho fokotseha ha modulus ea elastic ea litene tsa refractory e ntse e eketseha. Ha mocheso o ntse o eketseha mme o fihla boleng bo phahameng ba modulus ea elastic, ho hanyetsa ho apara hoa eketseha ka ho fokotseha ha modulus ea elastic. Mohlala, khanyetso ea abrasion ea litene tsa letsopa ho 1200 ~ 1350 ℃ e betere ho feta mocheso oa kamore. Ha mocheso o ntse o phahama ka holimo ho 1400 ° C, viscosity ea mokelikeli sehlahisoa sa refractory e theoha haholo ‘me ho hanyetsa ho apara ho fokotseha. Tse ling, tse kang litene tse refractory, li tla eketseha ha mocheso o ntse o phahama.

Ka litaba tse ka holimo, na u tseba haholoanyane ka litene tse refractory?
