Tlhophiso ka Lintho tse Bohlokwa le Sebopeho
1. Lithapo tsa ho Wellisa tse Thehiloeng Tšepeng
Lithapo tsa ho tjheseletsa tse entsoeng ka tšepe ke thepa e sebelisoang haholo ea ho tjheseletsa, e arotsoeng ka mefuta e latelang:
Lithapo tse thata tsa tšepe ea Pearlitic: E sebelisoa haholo-holo ho lokisa likarolo tsa mosebetsi tse se nang khatello e tlase, joalo ka li-shaft le li-gear. Bothata ba overlay bo tloha ho 20 ho isa ho 40 HRC. E na le bokhoni bo botle ba ho sebetsa le ho tiea ho babatsehang.
Lithapo tse thata tsa tšepe ea Martensitic: Karolo e ka hodimo e bopa sebopeho sa martensitic kamora ho tima, ka thata ya 40 ho isa ho 60 HRC. E fana ka kganyetso e ntle ya ho tlola mme e loketse di-workpiece tlasa maemo a mahareng le a kgatello e phahameng, ho kenyeletswa le dikhetla tsa crusher roll le meno a bakete ya excavator.
Lithapo tse thata tsa tšepe e entsoeng ka chromium e phahameng: E entsoe ka tšepe e nang le motsoako o phahameng e nang le chromium e ka bang 15% ho isa ho 30%. Palo e kholo ea mekhahlelo e thata ea chromium carbide e oela ka har'a sekoahelo, e fanang ka boima ba 55 ho isa ho 65 HRC. Mofuta ona o na le khanyetso e ikhethang ea ho tsofala le khanyetso e itseng ea mafome, 'me ke terata e thata e sebelisoang haholo indastering ea merafo le ea tšepe.
2. Lithapo tsa ho Wellisa tse Thehiloeng ho Nikele
Ka nickel e le matrix le chromium, molybdenum, boron le likarolo tse ling tsa alloying tse ekelitsoeng, ho koahela lithapo tse thata tse thehiloeng ho nickel ho na le khanyetso e ntle ea ho bola le khanyetso ea mocheso o phahameng. Bothata ba eona hangata ke 30 ho isa ho 50 HRC, 'me ho tiea ho molemo ho feta ha li-overlay tsa tšepe tse entsoeng ka chromium e phahameng. E sebelisoa haholo bakeng sa ho tiisa likarolo tse hlokang khanyetso khahlanong le khanyetso le khanyetso ea mocheso o phahameng, joalo ka libaka tsa ho koala li-valve, lijana tsa lik'hemik'hale le mahare a turbine ea mouoane. Theko ea eona e phahame haholo ho feta ea lithapo tse thehiloeng ho tšepe.
3. Lithapo tsa ho Wellisa tse Thehiloeng ho Cobalt
Ha li sebelisa cobalt e le karolo ea bohlokoa ea motsoako, lithapo tsena li na le bothata bo phahameng ba ho chesa, ho hanyetsa mafome le ho hanyetsa mokhathala oa mocheso. Li ka sebetsa ka ho tsoelang pele ho 600℃ ho isa ho 800℃. Li sebelisoa haholo-holo bakeng sa maemo a holimo a mosebetsi a kang li-valve tsa mocheso o phahameng, li-dies tsa ho betla tse chesang le mahare a turbine. Ka lebaka la litšenyehelo tse phahameng, boholo ba ts'ebeliso ea tsona bo lekanyelitsoe.
4. Lithapo tsa ho Wellisa tsa Tungsten Carbide tse Tiileng
Likaroloana tsa carbide ea tungsten li sebetsa e le mekhahlelo e thata 'me li kopantsoe le matrix ea tšepe. Ho koahela ho fihla boima ba 60 ho isa ho 70 HRC, 'me khanyetso ea eona ea ho roala e makhetlo a 2 ho isa ho a 3 ho feta ho koahela tšepe e tloaelehileng ea chromium e nang le chromium e ngata. E sebelisoa haholo-holo bakeng sa likarolo tse nang le khanyetso e matla ea ho roala e tlase, joalo ka li-cutterhead tsa mochini oa thebe, li-dredge cutter le li-chute tsa mashala. Bothata ba eona bo boholo ke ho robeha ho hoholo le khanyetso e fokolang ea tšusumetso.
Tlhophiso ka Tsamaiso ea Tlhahiso le Sebopeho
1. Lithapo tse tiileng tsa ho tjheseletsa tse thata
Lithapo tse tiileng tse tiileng, tse entsoeng ka ho qhibilihisa alloy le ho taka terata, li na le sebopeho se ts'oanang le se tsitsitseng, ts'ebetso e bonolo ea tlhahiso le litšenyehelo tse tlase. Li sebelisoa haholo bakeng sa ho tjheseletsa ka khase le ho tjheseletsa arc e ka tlas'a metsi.
2. Lithapo tsa ho Wellisa tsa Hardfacing tse nang le Flux-core
Mofuta ona oa terata o na le sheath e ka ntle ea tšepe e bobebe e tletseng phofo ea alloy, li-arc stabilizers, li-deoxidizer le likarolo tse ling. Tshebetso ea overlay e ka fetoloa ka mokhoa o feto-fetohang ka ho fetola foromo ea phofo. E na le bokhoni bo phahameng ba ho beha, arc ea welding e tsitsitseng le ponahalo e boreleli ea weld. Jwalo ka sehlahisoa se ntseng se hola ka potlako indastering ea hardfacing lilemong tsa morao tjena, karolo ea eona ea 'maraka e se e fetile butle-butle ea lithapo tse tiileng.
Tlhophiso ka Mokhoa oa ho Welding
Li arotsoe ka lithapo tse thata tse sirelelitsoeng ka khase, lithapo tse thata tse koahetsoeng ka metsing, lithapo tse thata tse sirelelitsoeng ka boithatelo le lithapo tse thata tse sirelelitsoeng ka khase tse tungsten. Har'a tsona, lithapo tse thata tse sirelelitsoeng ka boithatelo ha li hloke khase e sireletsang kantle, e leng se etsang hore li be ntle bakeng sa kaho ea kantle sebakeng seo 'me li sebelisoe haholo tokisong ea masimo a mesebetsi e meholo.
Melao-motheo ea Khetho bakeng sa Lithapo tsa ho Welding tsa Hardfacing
Khetho ea lithapo tsa ho tjheseletsa tse thata e tla nahaneloa ka botlalo lintlha tse tharo tsa bohlokoa: maemo a mosebetsi, tekanyetso ea litšenyehelo le litlhoko tsa kamora ts'ebetso.
Khetho e ipapisitse le mofuta oa ho roala le maemo a ts'ebeletso
Ho robeha ha khohlela ho sa kgatellong e tlase: Etella pele lithapo tsa tšepe tse nang le chromium e ngata kapa lithapo tsa tungsten carbide, tse kang LZ60 le D60.
Ho senyeha ha tšusumetso e mahareng le e phahameng: Khetha lithapo tsa tšepe tsa martensitic tse leka-lekaneng ho tiea le ho hanyetsa ho senyeha, joalo ka D50 le 414N.
Tšebeletso e senyang le e nang le mocheso o phahameng: Khetha lithapo tse thehiloeng ho nickel kapa cobalt, ho kenyeletsoa ERNiCrMo-4 le Stellite 6.
Tsosoloso ea litekanyo tsa li-shaft le li-gear: Sebelisa lithapo tsa tšepe tsa pearlitic-martensitic ho netefatsa hore mochini o sebetsa hantle.
Khetho e ipapisitse le tekanyetso ea litšenyehelo
Lithapo tse thehiloeng tšepeng hangata li theko ea 10~50 RMB ka kilograma, lithapo tse thehiloeng ho nickel ka 100~300 RMB ka kilograma, le lithapo tse thehiloeng ho cobalt tse fetang 500 RMB ka kilograma. Motheong oa ho fihlela litlhoko tsa ts'ebetso, lithapo tse thehiloeng tšepeng li khethoa ho fokotsa litšenyehelo.
Khetho e ipapisitse le litlhoko tsa kamora ts'ebetso
Haeba ho hlokahala ho sebetsa ka machining kamora ho tiisa, sebelisa lithapo tsa perela kapa tsa martensitic tse thatafetseng ka tlase ho 45 HRC. Haeba mosebetsi o ka kenngoa ts'ebetsong e tobileng ntle le ts'ebetso e 'ngoe, ho khothaletsoa lithapo tse thata haholo le tse hanyetsanang le ho tsofala haholo.
