Wolfram carbide
Tungsten carbide ke motsoako o entsoeng ka 50% tungsten le 50% carbon. Ho na le mekhoa e 'maloa e sebelisoang ho etsa motsoako, o tloaelehileng haholo oa ho sebelisana ha metallic tungsten le carbon ka mocheso ho tloha ho 1400 ho ea ho 2000 ° C. likhato tsa Celsius.Litšepe tse lebelo le phahameng
High speed steel (HSS) ke motsoako o kopanyang tšepe (tšepe le carbon) le likarolo tse ling tse kang chromium, molybdenum, tungsten, vanadium kapa cobalt. Lintho tse ling ntle le tšepe li ka etsa 20% ea sebopeho sa HSS, empa kamehla li feta 7%.Ho kenyelletsa lintho tsena ho tšepe ha ho bope HSS ka bohona, empa thepa le eona e tlameha ho tšoaroa ka mocheso le ho halefa.
High speed steel (HSS) e khona ho khaola thepa ka potlako ho feta tšepe e phahameng ea carbon, kahoo lebitso "lebelo le phahameng". Sena se bakoa ke ho thatafala ho hoholo le ho hanyetsa ha abrasion ha ho bapisoa le carbon e phahameng le lisebelisoa tse ling tsa lisebelisoa.
Ke hobane'ng ha tšepe le carbide e lebelo le phahameng li sebelisoa bakeng sa li-blade tsa scraper?
Lehare la scraper le tlameha ho etsoa ka thepa e thata ho feta ntho eo e e senyang hore e sebetse. Likarolo tse ling tsa alloying le mekhoa ea tlhahiso, joalo ka kalafo ea mocheso eo tšepe ea lebelo le phahameng e kentsoeng ho eona, e fana ka boima bo hlokahalang bakeng sa ho hohla.
Li-carbide scrapers li thata ho feta HSS. Sena se lumella hore li sebelisoe mefuteng e mengata ea thepa.
Li-scraper blades tse sa nkeheng sebaka
Li-scraper blades tse sa khoneng ho nkeloa sebaka li batla li entsoe ka tšepe ea lebelo le phahameng, kaha litšenyehelo tsa ho etsa lehare lohle le shaft ho tsoa carbide li ne li tla ba holimo haholo.Le hoja li-blades tsa scraper tse sa nkeloeng sebaka li entsoe ka tšepe e phahameng ea lebelo, karolo e nyenyane feela qetellong ea scraper e phekoloa mocheso le ho halefa. Sebaka se tšoaroang mocheso le mocheso hangata se fapana ka 'mala ho tloha ho tse ling tsa shaft.
Ke lisebelisoa life tse ka sebelisoang li-scraper blades?
