Submerged arc furnaces (SAFs) e fetola matla a motlakase ho arc mocheso le mocheso o hanyetsang ka li-electrode, ore e futhumatsang ka kotloloho kapa lisebelisoa tse tala tsa tšepe ho fihlela mocheso o phahameng-oa ho qhibiliha. Sengoliloeng sena se qhekella likarolo tsa bona tsa meralo, menahano ea phetolo ea matla, le lits'ebetso tse tloaelehileng tsa indasteri.
Likaroloana tsa Sebopeho sa Motheo
Sebopeho sa mantlha sa SAF se etsa qeto ea bokhoni ba eona ba ho fetola matla le botsitso, bo nang le likarolo tse tharo tse sebetsang:
- Sistimi ea Electrode: Ka tloaelo e sebelisa li-electrode tsa graphite ho tsamaisa hajoale ka phaposing ea sebōpi le ho hlahisa arc ea motlakase.
- Sebopeho sa Sebōpi: E na le lesela le refractory le khetla ea tšepe; e tlameha ho mamella mocheso o fetang likhato tse 1600 .
- Cooling System: E sireletsa likaroloana tsa bohlokoa-joalo ka li-electrode holders le khetla ea sebopi{1}}ka metsi{2}}li-circuits tse pholisang.
- Moqapi oa Moqapi: Karo-karolelano ea botenya ba lesela ho bophara ba electrode e ama ka ho toba ho tšoana ha tšimo ea mocheso.
Mokhoa oa ho Fetola Matla
Ketane ea phetisetso ea matla, ho tloha phepelong ea motlakase ho isa ho ho qhibiliha, e kenyelletsa mekhahlelo e meraro:
- Li-transformer li fetola -motlakase oa marang-rang a phahameng hore e be motlakase o tlase-oa matla, o phahameng{2}motlakase oa hajoale o loketseng arc botsitso.
- Litsamaiso tsa taolo li fetola maemo a li-electrode ho boloka bolelele bo nepahetseng ba arc lipakeng tsa li-electrode le lisebelisoa tse tala.
- Mocheso oa ho hanyetsa o hlahisoa ha hona joale ho feta tefiso ea sebōpi; sena se kopana le mocheso oa arc ho etsa mohloli oa mocheso o kopantsoeng.
- Li-Parameters tsa Bohlokoa: Matla a motlakase a bobeli le a electrode a lekanya mocheso oa letamo le qhibilihisitsoeng.
Likopo tse Tloaelehileng tsa Indasteri
Litšobotsi tsa eona tsa ho futhumatsa motlakase ka kotloloho li etsa hore e be bohlokoa haholo mefuteng e 'meli ea maemo:
- Metal Smelting: Karabelo ea phokotso ea litšepe tse refractory joalo ka li-ferroalloys le li-alloys tsa silicomanganese.
- Mineral Processing: Ho sebetsa ha lik'hemik'hale-tse phahameng tsa mocheso joalo ka ho senyeha ha lejoe la phosphate kapa ho qhibiliha ha titanium slag.
- Ha ho bapisoa le libono tsa motlakase tsa arc (EAFs), li-SAF li loketse hamolemo bakeng sa ho sebetsana le lisebelisoa tse tala tse phofshoana le mekhoa ea ho sebetsana e hlokang ho boloka mocheso nako e telele.
Litsamaiso tse ka sehloohong tse thusang
Ts'ebetso e tsoelang pele, e tsitsitseng e itšetlehile ka ho hokahanya likarolo tse tharo tse thusang:
- Electrode Regulator: Ka matla o lefella tšebeliso ea electrode ho boloka botsitso ba arc.
- Temperature Monitoring System: E kenyelletsa li-infrared pyrometers le{0}}likhamera tsa sebopi ho beha leihlo boemo ba letamo la ho qhibiliha.
- Setsi sa ho Tlosa Lerōle: E sebetsa-mocheso o phahameng oa khase e hlahisoang nakong ea ho qhibiliha.
- Tlhokomeliso ea Tšireletso: Litekanyo tsa botenya ba lebota la sebōpi li bohlokoa ho thibela likotsi tsa ho phatloha ha sebōpi.
O&M Consumables System
Likarolo tse tharo tsa lisebelisoa li hloka taolo ea bohlokoa nakong ea tlhahiso ea letsatsi le letsatsi:
- Lisebelisuoa tsa ho lokisa lesela la sebopi: Magnesia- kapa lik'habone{1}tse sebelisoang ho lokisa mabota a sebōpi.
- Lisebelisoa tsa Slag conditioning: E sebelisetsoa ho fetola metsi a slag le ho sireletsa lesela la sebōpi.
- Electrode peste: Lintho tse sebetsang tse hlokang ho tlatsoa nako le nako bakeng sa ho tsoela pele-li-electrode tsa ho baka.
- Mokhoa o matla haholoanyane: Theha lekhalo la khokahano lipakeng tsa mocheso oa sintering oa electrode peste le mojaro oa hajoale.
