What is Forged Metal: Mekhoa le Litšobotsi

Likarolo-tse Felletseng

 

Likarolo tsa tšepe tse entsoeng ka ho forging li kena tšebetsong e ikhethang ea tlhahiso. Tshebetso ena e bopa tšepe ka matla a hatellang a sebakeng seo 'me e etsa likarolo tse nang le botšepehi bo ikhethang ba sebopeho. Tšepe e holofala ka mekhoa ea ho otlanya, ho hatella kapa ho thetheha ka mocheso o itseng.

 

Traditional vs. Mekhoa ea Sejoale-joale ea ho Forging

Ka tloaelo litei tsa litšepe li ne li sebelisa lifensetere tsa mashala kapa tsa mashala tse nang le lisebelisoa tse bonolo tse kang lihamore le li-anvil. Forging ea sejoale-joale e fetohile haholo, 'me hona joale e sebelisa theknoloji e tsoetseng pele joalo ka libopi tsa motlakase le lisebelisoa tsa khase tse fanang ka taolo e betere ea mocheso. Mekhoa ea kajeno e boetse e kenyelletsa mechine e hatisang ka metsi, lihamore tsa moea, le mananeo a k'homphieutha a thusang ho etsa boqapi ho netefatsa tlhahiso e nepahetseng.

The forging process e etsahala maemong ana a mocheso:

• Ho qhekella ho chesang: Ho etsoa pakeng tsa 950-1250 ° C, e lumellang sebopeho se setle ka litlhoko tse fokolang tsa matla.
• Ho qhekella ka mofuthu: Ho etsoa ka 750-950 ° C, ho fana ka tekanyo pakeng tsa sebopeho le ho nepahala
• Cold forging: E ​​etsoa ka mocheso oa kamore ho fihlela ho 150 ° C, e fana ka phello e phahameng ea bokaholimo.

Liphetho tsa tlhahlobo ea fatše

Liteko tsa masimo li bontša ka ho hlaka hore na likarolo tsena li sebetsa ka tsela e fapaneng joang. Likarolo tsa maiketsetso li nka nako e telele ho 15-30% ho feta litšepe tse betliloeng litekong tsa ho tšoarella. Metallurgy ea phofo e hatetse pele haholo ka tsoelo-pele ea theknoloji. Mocheso o phahameng oa sintering o ntlafatsa matla a ho tsitsa, matla a ho khathala, le matla a matla.

Liphuputso tsena tsa liketsahalo li totobatsa phapang ea bohlokoa:
