Ihe na-emetụta njide oge nke workpiece na ihe ọkụ ọkụ eletrik

1. okpomọkụ okpomọkụ

N’okpuru ọnọdụ nkịtị, a na-ejikarị data eme ihe maka ịgbakọ n’ime ọkụ ọkụ eletrik. Dịka ọmụmaatụ, a na-agbakọ ígwè carbon na 1min/1mm, ebe alloy steel bụ 1.3 ruo 1.8 ugboro nke carbon ígwè. Ihe kpatara ya bụ na alloy ígwè nwere nnukwu ọdịnaya nke ihe ndị na-emepụta ihe. Ma na elu okpomọkụ (1000 ℃), ma ọ bụrụ na irè ọkpụrụkpụ bụ nnukwu, ala ịgba nke a ọnụọgụ na-eji, na elu ịgba nke irè ọkpụrụkpụ bụ obere.

2. Ọdịiche dị na akara nchara

Maka carbon ígwè na obere alloy ígwè, oge a chọrọ maka mgbasa nke carbides na homogenization nke austenite dị nnọọ mkpụmkpụ, ya mere, dị ka ọnọdụ ahụ, “efu” okpomọkụ nchekwa quenching nwere ike iji, nke nwere ike ebelata usoro okirikiri ma belata Quenching cracks. Maka nchara dị elu, ikpo ọkụ ọkụ na oge ijide oge kwesịrị ịgbatị nke ọma iji hụ na mgbasa na austenitization nke carbides. Enwere ike ime atụmatụ na 0.5 ruo 0.8min kwa milimita maka oge njide. Mgbe oke elu nke ikpo ọkụ dị 0.5min, okpomọkụ nkwụsị na-adabere na Were 0.8min na njedebe dị ala.
