2022 setene se secha sa chrome corundum

Melemo ea lihlahisoa: porosity e tlase, letsoalo le phahameng, matla a phahameng, mocheso o motle oa ho roala mocheso, ho hanela serame se feteletseng le mocheso o feteletseng, ho hanyetsa slag hantle le ho tšoarella hantle.

Tlhaloso ea Sehlahisoa

Litene tsa Chromium corundum tse sa sebetseng li entsoe ka Al2O3 le Cr2O3 e le lisebelisoa tsa mantlha tse tala. Ha e bapisoa le litene tse hloekileng tsa corundum, e na le litšobotsi tse betere, joalo ka ho qhibiliha, ho nolofatsa mocheso o fokolang tlasa mojaro, matla a ho fetoha ha maemo, mocheso o phahameng, mocheso o phahameng oa bophahamo ba molumo oa khanyetso le ts’enyeho ea slag.

Litene tsa Chrome corundum ke litene tsa corundum tse hanyetsang tse nang le Cr2O3. Ha ho futhumetse haholo, Cr2O3 le Al2O3 li theha tharollo e tiileng e tsoelang pele. Ka hona, ts’ebetso e phahameng ea mocheso oa litene tsa chromium corundum e betere ho feta litene tse hloekileng tsa corundum. Litene tsa chromium corundum tse sebelisitsoeng seboping sa peterole ea indasteri ea petrochemical e lokela ho ba silicon e tlase, tšepe e tlase, alkali e tlase, bohloeki bo phahameng, empa hape e na le letsoalo le phahameng. Litene tsa Chrome corundum li sebelisoa haholo, ‘me litaba tsa Cr2O3 li boholo ba 9% ho isa 15%.

litene tsa chrome corundum le tsona li bitsoa litene tsa chromium corundum tse phahameng tse sa keneng. Ke sehlahisoa se phahameng se khothalletsoang ‘marakeng lilemong tsa morao tjena. E hlophisitsoe ho tloha alumina e hloekileng ea Al2O3 le chromium oxide Cr2O3 e le lisebelisoa tse ka sehloohong tse tala. Ha e bapisoa le litene tse hloekileng tsa corundum, e na le litšobotsi tse betere, tse kang ho chesa metsi, mocheso o nolofatsang mojaro, matla a Flexural, mocheso o phahameng, botsitso ba molumo o phahameng oa mocheso le khanyetso ea slag. Setene sa Chrome corundum ke mofuta oa thepa ea boemo bo holimo e hanyetsanang, ‘me bophelo ba eona ba ts’ebeletso bo ka fihla likhoeli tse 10 ho isa ho tse 18 kamora basebelisi ba bangata ba leloala.

Tloaelo e bonts’itse hore ts’ebeliso ea litene tsa chromium corundum tse phahameng tse sa keneng ka har’a seteishene sa ho chesa sebōpi se futhumatsang bakeng sa ho futhumatsa likalimo tse kholo, khohlano e phahameng sebakeng ka seng le tlhahiso e phahameng, eseng feela e ka eketsang nako ea ts’ebeletso. ho tlanya mocha le ho fokotsa nako ea ho tima sebōpi, ho eketsa tlhahiso, ho fokotsa litšenyehelo tsa ts’ebeliso le ts’ebeliso ea ts’ebetso, le phokotso ea palo ea ho futhumatsa le ho futhumatsa ka potlako ho bakoang ke ho koala sebōpi bakeng sa tlhokomelo, e le hore bophelo ba sebopi bo ntlafatsoe, mme melemo e totobetseng ea moruo e ka fumaneha.
