Ho bopa ente ea tšepe⎮Metallurgy ea phofo⎮Mabapi le rona

• Ho etsa phofo ke mohato oa bobeli oa metallurgy ea phofo. Ke mokhoa oo phofo e hlephileng e entsoeng ka eona ka li-billet tse nang le sebōpeho se itseng, boholo, boima le matla.

• Phofo ka mokhoa oa ho theha ho fumana sebopeho se fanoeng le matla a 'mele oa phofo, o bitsoang compact.

Ho na le mekhoa e mengata ea ho etsa phofo, ntle le mokhoa o tloaelehileng oa ho bopa, tse ling li khetholloa e le mekhoa e khethehileng ea ho etsa. Ho etsa lefu ke mokhoa oa mantlha ka ho fetisisa.

ho hloka ho etsa mochine oa khatiso - pulp casting - loose sintering

Mekhoa e latelang e sebelisoa ho bopa lisebelisoa: khatello, die, hot, isostatic, rolling, centrifugal, extrusion, le ho phatloha.

• Mekhoa e khethehileng ea ho theha;

• ho bōptjoa ho tloaelehileng;

• pheko ea phofo;

•thiori ea khatello

Powder pretreatment e kenyelletsa ho annealing, screening, ho kopanya, granulating, le ho kenya mafura har'a lintho tse ling.

Tloaelehileng phofo shoa ho etsa

Ho etsa phofo ke mokhoa o sebelisoang ka ho fetisisa oa ho etsa phofo. E bua ka mokhoa oa ho kenya phofo e kopantsoeng ka mokhoa o ts'oanang ka har'a hlobo e koetsoeng ka tekanyo e itseng mocheso oa kamore, ebe o e hatella ka billet ka khatello e itseng ea yuniti ka mochine oa khatiso.

Mokhoa ona oa ho theha hangata o na le mehato e latelang: phofo ea boima, phofo ea ho tlatsa, ho hatella, ho tšoara khatello le ho hlobola.

Molao-motheo oa ho bopa

(1) Sebelisa hlobo ho fa phofo sebopeho se lakatsehang.

(2) Fana ka 'mele ka boholo ba oona bo nepahetseng.

(3) Hlalosa porosity e hlokahalang ea billet le mofuta oa porosity.

(4) Fana ka 'mele ka tekanyo e nepahetseng ea matla le boima bakeng sa ho tšoara.

Mokhoa oa ho hatella

Ho hatella ka tsela e sa lekanyetsoang: "concave" e shoa 'me punch e ka tlaase ha e sisinyehe,' me sekontiri se ka holimo se hatelloa ke unidirectional.

Tse peli pelessing: "concave die" e tsitsitse, 'me sekontiri se ka holimo le se tlaase se hatelloa ka nako e le' ngoe ka likhatello tse lekanang le tse fapaneng.

Ho hatella ho phaphametseng: setebele se tlase se tsitsitse, concave die e tšehetsoa ke liliba, li-cylinders, li-cylinders, joalo-joalo, 'me e ka phaphamala ka mor'a ho hatelloa.

Mokhoa oa ho hatella

Mokhoa oa ho hatella o ka aroloa ka mekhahlelo e mene:

(1) Likaroloana tsa phofo lia sisinyeha, masoba aa fokotseha, ’me likaroloana lia penyane;

(2) Phofo e hatelloa ka thata, 'me likaroloana tse nyenyane li kenngoa ka har'a lekhalo pakeng tsa likaroloana tse kholo,' me likaroloana li qala ho senyeha;

(3) Karolo ea concave le convex ea bokaholimo ba karoloana ea phofo e hatelloa ebe e kenngoa ka har'a boemo bo tiileng ba ho ikopanya;

(4) Mosebetsi o thata oa likaroloana tsa phofo ho isa boemong bo lekanyelitsoeng, ho eketsa khatello, likaroloana tsa phofo li senyeha 'me kristale e hloekisoa.

Kamano pakeng tsa boima ba tšepe phofo le khatello ea khatello

Phello ea bohloeki ba phofo

Ka lebaka la mokhoa o fapaneng oa ho etsa phofo, ho hloeka ha phofo ha ho tšoane, 'me phofo e na le palo e itseng ea litšila. Litšila ka phofo li atisa ho ba ka sebōpeho sa li-oxide tsa tšepe.

The metal oxide powder hangata e thata ebile e brittle, 'me haholo-holo e ajoa holim'a phofo ea tšepe, e leng ho eketsang ho hanyetsa ho hatella le ho senya ts'ebetso e hatellang.

The manufacturability ea phofo ho etsa likarolo sebopeho

1. Ho etsa hore ho be bonolo ho etsa hlobo le ho kopanya, leka ho khetha moralo o otlolohileng, o nang le symmetrical o qobang ho fapana ho feteletseng ha karolo le li-grooving tse moqotetsane, libaka tse chitja, joalo-joalo.

2. Qoba mabota a masesaane a lehae ho nolofatsa ho kopana ha phofo le ho thibela mapetsong.

3. Qoba li-grooves le masoba maboteng a mahlakoreng ho thusa ho kopanya kapa ho fokotsa li-blocks tse setseng.

4. Qoba ho eketsa sebaka sa cross-sectional hammoho le tataiso e hatellang ho tsamaisa compaction. Likhutlo li lokela ho pota-pota mateanong a lebota ka leng ho thusa ho tiisa le ho qoba khatello ea maikutlo.

Karolo ea Powder

Mofuta oa pele oa likarolo: ho hatella unidirectional, lerako le tšesaane, sebopeho se ikhethileng, karolo ea tafole (botenya ba lebota hangata bo fihla ho 6.35mm)

Mofuta oa bobeli oa karolo: karolo ea tafole, bophahamo leha e le bofe le sebōpeho, e tlameha ho ba likarolo tse hatellang tse peli.

Karolo ea Boraro: Karolo ea litafole tse peli, tsa bolelele bofe kapa bofe le sebopeho, tse tlamehang ho hatelloa ka mahlakoreng ka bobeli

Mofuta oa bone oa likarolo: litafole tse ngata, bolelele le sebopeho sefe kapa sefe, li tlameha ho sebelisa likarolo tse hatellang tsa litempe tse fapaneng.
