High hardness refractory Brown Fused Alumina
Tlhaloso ea Sehlahisoa
Brown fused alumina bauxite e le lisebelisoa tse tala, mashala, tšepe, mocheso o phahameng ka holimo ho likhato tse 2000 ka ho qhibiliha ha arc, polasetiki e silang ea leloala, karohano ea makenete ho tšepe, skrine e arotsoe ka mefuta e fapaneng ea boholo ba likaroloana, sebopeho se teteaneng, boima bo phahameng, karoloana e entsoeng. globular, ho kopanya ho phahameng ho loketse ho etsa ceramic, resin abrasive le ho sila, polishing, sandblasting, casting, joalo-joalo, le eona e ka etsoa. e sebelisetsoang ho etsa li-refractories tse tsoetseng pele.
Brown corundum mesebetsi ea eona ea mantlha:
1.Ka lebaka la matla a eona a phahameng le lisebelisoa tse ling, e sebelisetsoa ho akhela nozzle ea tšepe e thellang, ho qhibilihisa litšepe tse sa tloaelehang, li-alloys tse khethehileng, li-ceramics, lerako la sebōpi (lebota le phala); Lintho tsa 'mele le tsa lik'hemik'hale, spark plug, mocheso - oxidation e hanyetsanang - ho roala ho hanyetsanang.
2.Ka lebaka la litšoaneleho tsa boima, thobalano e ntle, matla a phahameng, tsamaisong ea lik'hemik'hale, e sebelisoang e le mefuta e sa tšoaneng ea lijana le liphaephe, likarolo tsa pompo ea lik'hemik'hale; Etsa likarolo tsa mochini, mefuta eohle ea hlobo, joalo ka hlobo ea terata, pentšele molomo oa hlobo oa pentšele, joalo-joalo; Etsa lisebelisoa, li-abrasives tsa hlobo, lisebelisoa tse thibelang likulo, manonyeletso a batho, lesale la ho tiisa joalo-joalo.
3.Lisebelisoa tsa ho kenya lisebelisoa tsa Corundum, tse kang litene tse khanyang tsa corundum, bolo ea corundum hollow le lihlahisoa tsa fiber, tse sebelisoang ka mefuta e sa tšoaneng ea lerako la sebōpi le holimo, ka bobeli ho boloka mocheso. Lehlabathe la boholo ba karolo ea Emery le entsoe ka emery block ea maiketsetso, ho sebelisoa rolara, ho sila bolo, barmark le lisebelisoa tse ling, boholo ba likaroloana ka F8-F325. Haholo-holo e sebelisetsoang ho bentša, ho sila, ho sila indasteri, joalo-joalo, e ka boela ea hlatsuoa ho ea ka litlhoko tsa bareki, pickling le ts'ebetso e 'ngoe, ho finyella litlhoko tse fapaneng tsa bareki.
Tlaase k'habone sootho corundum ka mor'a sebōpi le tshebetso e khethehileng ea reprocessing, fokotsa dikahare tsa masala carbon corundum sootho, e le hore sehlahiswa e sebelisoa e sa pulverized, eseng ho phatloha, toughness ke abrasives indasteri, refractory indasteri thepa e tala. Haholo-holo e sebelisoa bakeng sa li-abrades tsa ceramic, li-abrades, li-abrades tsa manyolo, mabanta, li-abrades tse koahetsoeng, joalo-joalo, ho ea ka likarolo tse setseng tsa carbon li arotsoe ka: calcined sootho corundum C ≤0.05%, corundum e tlaase ea carbon C ≤0.10%, corundum e tloaelehileng e sootho C. ≤0.15%.
