Gịnị bụ quenching uru nke elu-ugboro quenching ngwá n’onwe ya
Gịnị bụ quenching uru nke akụrụngwa na-emenyụ ọkụ ugboro ugboro onwe ya
Ngwa nke ikpo ọkụ dị elu na-arụ ọrụ na ụlọ ọrụ ígwè ruo ogologo oge, jiri nwayọọ nwayọọ dochie ngwá ọrụ ọgwụgwọ okpomọkụ nke omenala, na mmepe nkà na ụzụ na-aga n’ihu na usoro ígwè iji melite arụmọrụ ọrụ nke workpiece. Ụdị ihe abụọ dị n’etiti etiti na-emenyụ ọkụ, bụ nke yiri nnukwu nkwụsị ọkụ, nwere uru nkà na ụzụ yiri nke ahụ, ma a na-ahọrọ ngwá ọrụ nkwụsịtụ dị iche iche dị ka ihe dị iche iche chọrọ na nkà na ụzụ. Taa, ka anyị leba anya na uru ndị na-emenyụ ọkụ dị n’ime ngwa ndị na-emenyụ ọkụ ugboro ugboro.
High-frequency quenching tumadi na-eji ụkpụrụ nke electromagnetic induction, na induced ugbu a eme nwere ike mepụta usoro kpo oku, okpomọkụ ọgwụgwọ na ndị ọzọ Filiks na workpiece. Mgbe ahụ, ọ nwere njirimara na uru nke ngwá ọrụ nkịtị na-enweghị. Isi uru pụtara ìhè bụ:
1. Elu nke workpiece adịghị mfe oxidized. N’ihi kpo oku, workpiece dị mfe na kọntaktị na oxygen, na elu na-oxidized, nke ga-emetụta kpo oku mmetụta nke workpiece. Kama nke ahụ, usoro nkwụsị nke dị elu ọ bụghị nanị na ọ bụghị nanị na-eme ka oxidation dị ukwuu, ma ọkụ ọkụ na-agba ọsọ nke workpiece na-adịkwa ngwa ngwa, nke na-eme ka ọrụ ahụ dịkwuo mma, na workpiece n’onwe ya adịghị enwekarị nkwarụ.
2. Ụkpụrụ nke elu oyi akwa siri ike nke elu-frequency quenching workpiece bụ n’ime 1-1.5mm, nke na-abụghị otu ihe ahụ dị ka etiti ugboro quenching. Omimi nke oyi akwa siri ike nke nkwụsị nke etiti etiti nwere ike iru n’ime 1-5mm, ya mere, a na-eji nkwụsịtụ oge na-eme ka ọ bụrụ ihe na-eme ka ọkpụkpụ dị elu na-enweghị ike izute usoro a chọrọ. N’ezie, ọ bụrụ na ọ bụ a workpiece na a miri ike oyi akwa, anyị na-eji ike-ugboro quenching usoro.
3. Usoro ikpo ọkụ nke ngwá ọrụ bụ ikpo ọkụ na-adịghị na kọntaktị, nke nwere ike ikpo ọkụ nke abụọ deformed workpiece ngwa ngwa.
4. The quenching usoro nke workpiece nwere ike na-akpaghị aka ịchịkwa, na ọ nwere ike na-onwem na a quenching igwe ngwá ọrụ nweta na-aga n’ihu quenching, segmented quenching na ụdi scanning. Usoro a bụ nnọọ adabara ụfọdụ workpieces na siri ike chọrọ.
5. Usoro ọgwụgwọ okpomọkụ na-arụ ọrụ nke ngwá ọrụ nkwụsịtụ ugboro ugboro dị nnọọ mfe na ọnụ ala.
