Refractory bolo (mocheso oa polokelo ea mocheso)
Refractory bolo (mocheso oa polokelo ea mocheso)
1. High ea alumina bolo e na le litšobotsi tse tsa matla ho kena moea ho hanyetsa le ho hanyetsa slag. Bolo ea kristale e bonoang e ka nkeloa sebaka habonolo le ho hloekisoa, ‘me e ka sebelisoa hape.
2. Main tobileng tsa bolo refractory: Φ40mm Φ50mm Φ60mm Φ70mm
3. Lisebelisoa tsa lihlahisoa tsa bolo tse sa sebetseng li arotsoe ka: aluminium e phahameng, corundum le zirconium corundum.
4. Ho na le mefuta e mengata ea libolo tse haelloang, tse ka sebelisoang litsing tse fetohang le tse tlase tsa mocheso, liphetolelo, li-converter tsa hydrogenation, litanka tsa desulfurization, le libolo tse hanyetsang le lisebelisoa tsa ho sokoloha tse futhumatsang tse nkeloang sebaka ke sebopi sa mollo o chesang indastering ea tšepe le ea tšepe. .
5. Mocheso oa polokelo ea letsopa libolo tse hanyetsang li na le melemo ea matla a phahameng le ho itoanela ho apara; mocheso o moholo oa mocheso le mocheso oa mocheso, bokhoni bo phahameng ba ho boloka mocheso; li-porcelain tsa polokelo ea mocheso li na le botsitso bo botle ba mocheso mme ha ho bonolo ho li robeha ha mocheso o fetoha ka tšohanyetso. Bolo ea polokelo ea mocheso e loketse haholo bakeng sa polokelo ea mocheso oa polokelo ea mocheso oa lisebelisoa tsa karohano ea moea le phatloha ea sebōpi sa khase ea sebopi sa tšepe. Mocheso oa polokelo ea mocheso o eketsa ho futhumatsa ha khase le moea habeli, ‘me bolo ea polokelo ea mocheso ea letsopa e etsa hore mocheso o tukang o fihlelle tšepe e potlakileng ho futhumatsa billet. Litlhoko.
6. Libolo tse phahameng tsa alumina ceramic refractory, li-alumina tse phahameng, boleng bo phahameng, matla a phahameng a ho itšireletsa, ho itšireletsa hantle, lik’hemik’hale tse tsitsitseng, ho hanyetsa mocheso o phahameng, libolo tse phahameng tsa alumina ceramic li sebelisoa haholo, ‘me li ka sebelisoa e le li-filler tsa lik’hemik’hale. Libolo tse phahameng tsa alumina ceramic le tsona li ka sebelisoa e le litaba tsa ho sila. Libolo tse phahameng tsa alumina ceramic tse sebelisoang haholo li sebelisoa haholo lik’hemik’hale, mechini, elektroniki, ts’ireletso ea tikoloho le likarolo tse ling.
1. Boto e phahameng ea aluminium e sa sebetseng hangata e bua ka litaba tsa Al2O3. Ntlha e tsebahalang ke litaba tsa aluminium oxide ka lihlahisoa tse tala tsa bolo e hanyetsang. Lisebelisoa tsa aluminium li khetha boemo ba thepa e ‘ngoe e fapaneng. Ka hona, ke index ea mantlha ea ts’ebetso ea bolo e sa sebetseng. Li-aluminium tse phahameng tsa aluminium li ka aroloa ka mefuta e mene ho latela likarolo tsa aluminium: boemo ba pele ba aluminium e nang le lintlha tse 75; libolo tsa boemo ba bobeli tsa aluminium e phahameng, ZN-65 e nang le 65% ea aluminium; libolo tsa boemo ba boraro tse phahameng tsa aluminium, tse nang le likarolo tsa aluminium 55% The ZN-55.
2. Bongata ba bongata ke karo-karolelano ea boima bo ommeng ba bolo e hanyetsang ho ea ho palo ea eona kaofela, ‘me yuniti ke g / cm3. Boima ba bongata bo bonts’a ho ts’oana ha bolo e sa sebetseng. Ka kakaretso, bongata ba bongata ba libolo tse harelang bo amana haufi le porosity ea eona le sebopeho sa diminerale. Ka bolo e hanyetsang, ho eketseha ha bongata ba bongata, ho ntlafatsa boleng ba sehlahisoa. Matšoao a bophahamo ba mefuta e mene ea libolo tse sa sebetseng ke: sehlopha sa pele se phahameng sa alumina bolo ≥ 2.5; sehlopheng sa bobeli se phahameng ea alumina bolo ≥ 2.3; sehlopha sa boraro phahameng ea alumina bolo ≥ 2.1.
3. The porosity e bonahalang ke karolelano ea bophahamo ba modumo ea pores bulehileng ea bolo refractory ho palo yohle. Ka kakaretso, likhase tsa slag le tse kotsi ka sebonong li senya bolo e ts’oanang ka boeona ka masoba a bulehileng. Ka hona, ho hlokahala hore ponahalo e hlakileng ea bolo e hanyetsang e nyane kamoo ho ka khonehang. Ponahalo e hlakileng ea mefuta e mene ea libolo tse sa sebetseng ke: libolo tsa aluminium e phahameng ea boemo ba pele≤24%; libolo tsa boemo ba bobeli tse phahameng tsa aluminium≤26%; boemong ba boraro-phahameng ea alumina balls≤28%.
4. Boleng ba khatello ea khatello mochesong oa kamore bo na le tšusumetso e kholo tlhahisong, ts’ebelisong le ts’ebelisong ea bolo e sa sebetseng, ka hona ho hlokahala boleng bo phahameng ba ho hanela khatello. Yuniti e hlahisoa ho KN. Litekanyetso tsa khatello ea khatello ea mefuta e mene ea libolo tse sa sebeliseng mocheso oa kamore ke: bolo e khethehileng ea aluminium special 25; sehlopha sa pele se phahameng aluminium bolo ≥ 15; sehlopha sa bobeli se phahameng aluminium ball ≥ 10; sehlopha sa boraro phahameng aluminium bolo ≥ 8.
5. Mocheso o nolofatsang mojaro oa bolo e hanyetsang e bua ka mocheso oo o holofalang nakong ea ts’ebeliso. Mocheso o nolofatsang mojaro oa mefuta e mene ea libolo tse sa sebetseng ke: libolo tse phahameng tsa aluminium e phahameng -1530 ℃; libolo tsa aluminium e phahameng ea sehlopha sa pele ≥1480 ℃; libolo tsa sehlopheng sa bobeli tse phahameng tsa aluminium ≥1450 ℃; le libolo tsa aluminium e phahameng ea sehlopha sa boraro ≥1400 ℃.
6. Thermal shock botsitso ke bokhoni ba bolo refractory ho hanela liphetoho mocheso mocheso batang haholo le mocheso ka potlako. Ho lekanya lenane lena la ts’ebetso ea bolo e sa sebetseng, hangata e hlahisoa ka makhetlo a ‘maloa tlasa boemo ba ho phomola ha metsi a 1100.. The mogote makala botsitso ea mefuta e mene ea libolo refractory ke: khethehileng phahameng ea alumina bolo times makhetlo a 10; sehlopheng sa pele phahameng ea alumina bolo, sehlopheng sa bobeli phahameng ea alumina bolo, ‘me sehlopheng sa boraro se phahameng ea alumina bolo times makhetlo a 15.
Litsupa tse supileng, tsa ‘mele le tsa lik’hemik’hale:
