Mekhoa ea ho Etsa Likonopo tsa Carbide

Tungsten carbide ke e 'ngoe ea lisebelisoa tse sebelisoang lefatšeng ka bophara indastering. Konopo ea carbide e entsoe ka tungsten carbide, kahoo e na le thepa ea carbide e entsoeng ka samente. Sebopeho sa cylinder ea likonopo tsa tungsten carbide se etsa hore ho be bonolo ho kenya lisebelisoa tse ling ka ho kenya mocheso le ho hatella mohatsela. Hobane li-buttons tsa carbide li na le litšobotsi tsa ho thatafala, ho tiea le ho tšoarella, ho tloaelehile ho li bona maemong a fapaneng a kang ho cheka seliba, ho cheka majoe, ho sebetsa tseleng le ketsahalo ea merafo. Empa konopo ea carbide e etsoa joang? Sehloohong sena, re tla araba potso ena.

1. Tokisetso ea Lintho tse tala

Mekhoa e latelang e hloka lisebelisoa tsa phofo ea WC le phofo ea Cobalt. Phofo ea WC e entsoe ka ores ea tungsten, e rafshoang le ho lefisoa ho tsoa tlhahong. Ores ea Tungsten e tla ba le mefuta e fapaneng ea liphetoho tsa lik'hemik'hale, pele ka oksijene ho fetoha tungsten oxide ebe ka khabone ho fetoha phofo ea WC.

2. Ho Kopanya Phofo

Hona joale ke mohato oa pele oa kamoo lifeme li etsang meno a carbide. Lifeme li tla kenya li-binders tse ling (Cobalt powder kapa Nickel powder) ka phofo ea WC. Litlama li tšoana le "sekhomaretsi" bophelong ba rona ba letsatsi le letsatsi ho thusa ho kopanya tungsten carbide ka thata haholoanyane. Basebetsi ba tlameha ho lekola phofo e tsoakiloeng ho netefatsa hore e ka sebelisoa mehatong e latelang.

3. Ho Wet Milling

Nakong ea ts'ebetso ena, phofo e kopanyang e tla kenngoa ka har'a Mochini oa ho Tlisa Ball ebe o siloa ka mokelikeli o kang metsi le ethanol. Mokelikeli ona o ke ke oa itšoara ka lik'hemik'hale empa o thusa ho sila.

4. Spray Ho omisa

Mokhoa ona o lula o etsoa ka har'a omisitsoeng. Empa lifeme tse fapaneng li ka khetha mefuta e fapaneng ea mechini. Mefuta e 'meli e latelang ea mechine e tloaelehile. E 'ngoe ke Vacuum Dryer; e 'ngoe ke Spray Drying Tower. Ba na le melemo ea bona. Fafatsa mosebetsi oa ho omisa ka mocheso o phahameng le likhase tse sa sebetseng ho etsa mouoane oa metsi. E ka fetoha mouoane boholo ba metsi, e leng se etsang hantle ho mekhoa e 'meli e latelang ea Pressing and Sintering. Vacuum Drying ha e hloke mocheso o phahameng hakaalo empa e bitsa chelete e ngata haholo ho e hlokomela.

5. Ho hatella

Ho hatella phofo ka libopeho tse fapaneng tseo bareki ba li hlokang, basebetsi ba tla etsa hlobo pele. Li-buttons tsa Carbide li na le libopeho tse fapaneng e le hore u ka bona mefuta e fapaneng ea li-dies, tse nang le hlooho ea conical, hlooho ea bolo, hlooho ea parabolic, kapa hlooho ea khaba, e nang le li-chamfers tse le 'ngoe kapa tse peli, le tse nang le li-pinholes kapa tse se nang tsona. Ho na le litsela tse peli tsa ho bopa. Bakeng sa li-buttons tse nyane, basebetsi ba tla tobetsa ka mochini o ikemetseng; bakeng sa e kholoanyane, basebetsi ba tla hatella ka mochini oa hydraulic press.

6. Sintering

Basebetsi ba tla kenya malebela a petelitsoeng ka carbide holim'a poleiti ea graphite le ho Hot Isostatic Pressing (HIP) Sintered Furnace tlas'a mocheso o ka bang 1400˚ C. Thempereichara e tlameha ho phahamisoa ka lebelo le tlase e le hore konopo ea carbide e honyehe butle 'me e felile. konopo e na le tshebetso e betere. Ka mor'a ho sintering, e tla honyela 'me e be le hoo e batlang e le halofo ea molumo joaloka pele.

7. Tlhahlobo ea boleng

Licheke tsa boleng li bohlokoa haholo. Lisebelisoa tsa carbide li hlahlojoa pele bakeng sa thepa e kang boima, cobalt magnetic, le microstructure ho hlahloba masoba kapa mapetsong a manyenyane. Ho lokela hore ho sebelisoe micrometer ho lekola boholo ba eona, bophahamo le bophara ba eona pele e paka.
