Kenyelletso ea Hardfacing le Lisebelisoa tsa eona tsa Carbide

Lilemong tse fetileng hardfacing e ile ea e-ba taba ea tsoelo-pele e matla e amanang le lisebelisoa tse hanyetsanang le ho apara. Hardfacing, eo hape e tsejoang e le "Hardsurfacing", ke ts'ebeliso ea litšepe tsa weld tse hahiloeng kapa tse sa senyeheng holim'a karolo e itseng ka ho tjheseletsa kapa ho kopanya ho hanela ho hoholeha, ho bola, mocheso o phahameng kapa ts'usumetso. Ke ho beha liphahlo tse teteaneng tsa thepa e thata, e sa senyeheng holim'a karolo e tsofetseng kapa e ncha e ka sebelisoang ho sebetsa. Ho fafatsa ka mocheso, ho fafatsa fuse le lits'ebetso tsa welding hangata li sebelisoa ho sebelisa lera le thata. Alloy e joalo e ka behoa ka holim'a metsi, moeling, kapa feela ntlha ea karolo e lokelang ho roala. Li-deposit tsa welding li ka sebetsa ka holim'a metsi le ho khutlisa likarolo tse eketsang bophelo ba bona ba ts'ebeletso. Welding ke theknoloji ea bohlokoa ho phethahatsa litlhoko tsena le ho sebelisa li-alloys tse thata. Likarolo tsa mantlha tse kang li-crushers li pepesehetse ho koaleha haholo 'me li hloka mehato e sebetsang hantle ea ts'ireletso ea holim'a metsi ho qoba linako tse theko e boima le ho fokotsa litšenyehelo bakeng sa likarolo tse ling tse turang. Ts'ebetso ena e amohetsoe ho pholletsa le liindasteri tse ngata tse kang Cement, Mining, Steel, Petro-chemical, Power, Sugar cane le Lijo.

Tungsten carbide ke e 'ngoe ea lisebelisoa tse thata ka ho fetisisa tse fumanehang bakeng sa tšebeliso ea indasteri. E ke ke ea qhibilihisoa ke lelakabe lefe kapa lefe le Tloaelehileng la mocheso o tlase. E boetse e na le brittle. Bakeng sa merero e thata, e sithabelitsoe mme e sebelisoa hammoho le tšepe e "tlamang". Likaroloana tsa tungsten carbide hangata li koaletsoe ka molamu oa tšepe oa tšepe.

ZZBETTER e na le lisebelisoa tse 'maloa tsa ho tjheseletsa tse thata tse kang tse latelang:

1.Likahare tsa Tungsten Carbide Wear:

2.Li-grits tsa Tungsten Carbide: Tungsten carbide grit e fana ka tšireletso e tšoarellang nako e telele libakeng tsa moaparo o phahameng oa abrasive. E sebelisetsoa ho sireletsa likarolo tse theko e boima tse kang li-bulldozer blades, meno a libakete, ho sila lehong, lihamore, meno a trencher, le mefuta e mengata ea lintho tse ling tse ka sebelisoang. Tungsten Carbide grit ke mokhoa o sebetsang oa ho sireletsa mochini le likarolo tsa mochini ka ho fana ka keketseho e kholo ea bophelo bo bolelele ba likarolo tseo. Sena se fokotsa nako ea ho theoha 'me se fokotsa litšenyehelo tse amehang ka likarolo tse sa sireletsoeng.

3.Lithupa tse kopantsoeng tse nang le Carbide Insets: Lithupa tsena tse nang le ts'ebetso e phahameng li sebelisa lisebelisoa tsa rona tsa carbide tse u fang likarolo tse bohale tse bohale le matla a hlokahalang libakeng tsa bohlokoa tsa sesebelisoa sa hau sa ho sila.

4.Lithupa tse kopantsoeng tsa Nickel Carbide: Melamu ea motsoako oa nickel carbide e 'nile ea e-ba mokhoa o thata le oa ho lokisoa ha li-cutters tse tsitsitseng' me li sebelisoa e le tšireletso bakeng sa li-stabilizers le reamers indastering ea oli le khase. Li-pellets tse kholo tsa tungsten carbide li fana ka khanyetso ea abrasion ha li-pellets tse ntle li sireletsa matrix ho tloha ho senyeha le ho senyeha. Nickel matrix e fana ka khanyetso ea mocheso o phahameng oa mocheso, e sireletsang 'mele o monyenyane le ho lumella ho nchafatsoa ha sehahi le ho sebelisa hlooho hape.

5.Thapo ea ho Welding e Flexible: Thapo e bonolo ea welding e entsoe ka tungsten carbide ea cast, spherical cast tungsten carbide kapa motsoako oa tse peli joalo ka karolo e thata, phofshoana e ikemetseng ea nickel alloy bakeng sa mohato oa bonding, ho latela karolo e itseng ea tlamahano e tsoakiloeng, ho bopa ha extrusion, ho omisa, ebe e etsoa ka terata ea nickel.

6.Lithupa tsa Nickel Silver Tinning: Lithupa tsa tšepe tsa nickel ke lithupa tsa oxyacetylene tse sebelisoang ka kakaretso bakeng sa ho cheselletsa litšepe tse fapaneng tse nang le ferrous le tse se nang ferrous, joalo ka tšepe, tšepe e entsoeng ka tšepe, tšepe e bonolo, le lisebelisoa tse ling tsa nickel. Hangata li sebelisoa bakeng sa ho kopanya li-alloys tsa koporo, tsa boronse le tsa koporo hammoho le ho aha libaka tse tsofetseng.

7.Lahlela phofo ea Tungsten Carbide: Cast tungsten carbide powder, eo hangata e bitsoang W2C, ke thepa e thata ka ho fetisisa e sebelisoang mefuteng e fapaneng ea ts'ebeliso. Ka sebopeho sa eutectic, ntlha e phahameng ea ho qhibiliha le ho thatafala, e ka thusang ho sireletsa le ho apara thepa ea ho hanyetsa. Thepa e etsoaho tswa motswakong wa carbon, tungsten le tungsten carbide powder mme e mmala wa silifera/e tshehla ka sebopeho se thibane sa boloko.

8.Tungsten Carbide Pellet Welding melamu: Ha ho bapisoa le phofo ea cast tungsten carbide, li-pellets tsa tungsten carbide li na le tšusumetso e ntle le ho hanyetsa ho apara. E na le litšobotsi tsa ho tjheseletsa ha nako e le 'ngoe ntle le reflow soldering. Li-pellets li chitja; friction coefficient e nyane, e ka fokotsang ho roala ha casing le ho boloka chelete e ngata.

P: Na hardfacing ke ea bohlokoa? 

Hardfacing e ka finyelloa ho sebelisoa mekhoa e sa tšoaneng, ka lebenkeleng le tšimong, e leng se etsang hore e be le mekhoa e mengata haholo le e theko e tlaase. Ho feta moo, ho sebelisa ts'ebetso ena likarolong tse ncha ho ka eketsa bophelo ba tšebeletso ka 300%. Leha ho le joalo, haeba u na le likarolo tse apereng ka thata, u ka boloka ho fihla ho 75% ho bapisoa le litšenyehelo tse ling.

Ho phethela, hardfacing ke mokhoa o feto-fetohang ka ho fetisisa oa ho ntlafatsa bophelo ba karolo e tsofetseng; hardfacing ke mokhoa o khethiloeng ka ho fetisisa matsatsing ana bakeng sa ho fokotsa litšenyehelo tsa ho fetola; hardfacing e fokotsa nako ea ho theoha hobane likarolo li nka nako e telele 'me li-shutdown tse fokolang li hlokahala ho li nkela sebaka; hardfacing ka etsoa ka thepa efe kapa efe tšepe sebelisa mefuta e fapaneng ya dithulaganyo tjheseletsa.

Haeba u thahasella lihlahisoa tsa tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha tse ling, u ka IKOMELA LE RONA ka mohala kapa ka poso ka ho le letšehali, kapa RE ROMELETSE MAIL botlaaseng ba leqephe lena.
