Mefokolo le Mehato ea ho Loantša lintho tse kholo: Sebopeho sa microstructure le thepa e sa lekaneng

Li-forging tse kholo, ka lebaka la boholo ba bona bo boholo, mekhoa e mengata, potoloho e telele, ho se ts'oane ha ts'ebetso, 'me lintho tse ngata tse sa tsitsang, hangata li etsa hore ho se ke ha e-ba le ho tšoana ho tebileng ho microstructure, e le hore ba se ke ba feta tlhahlobo ea thepa ea mechine, tlhahlobo ea metallographic le bao e seng ba- ho lemoha mefokolo e senyang.

Ka lebaka la ho arohana ha lik'hemik'hale tsa lik'hemik'hale, ho bokella ho kenyelletsoa le mefokolo e sa tšoaneng ea pore ka ingot;
Ha ho futhumatsa, mocheso o fetoha butle-butle, kabo ha e lekane, khatello ea ka hare e kholo, sekoli se ngata;
Mocheso o phahameng le nako e telele ea ho qhekella, khatello ea maikutlo ea sebakeng seo le deformation ea sebaka seo, boemo ba phallo ea polasetiki, tekanyo ea compaction, kabo ea deformation e fapane haholo;
Nakong ea ho pholile, mokhoa oa ho jala o lieha, phetoho ea lisele e rarahane 'me khatello e eketsehileng e kholo.
Lintlha tsohle tse ka holimo li ka lebisa ho inhomogeneity e tebileng ea ts'ebetso ea lisele le boleng bo sa tšoaneleheng.
Mehato ea ho ntlafatsa ho tšoana hamekgatlo e meholo:
1. Amohela theknoloji e tsoetseng pele ea ho qhibilihisa ho ntlafatsa boleng ba metallurgic ea ingot ea tšepe;
2. Adopt control forging, laola thekenoloji ea ho pholisa, ho ntlafatsa ts'ebetso ea thekenoloji, le ho ntlafatsa boemo ba tekheniki le moruo oa tlhahiso e kholo ea forging.
