Izinkinga eziningana ezidinga ukunakwa i-high-frequency quenching yensimbi enensimbi?

1. Ukuqina kwe-annealing: ubulukhuni kanye nesakhiwo sezingxenye ezifakwe emanzini kufanele zihlolwe ngaphambi kokwelashwa kokushisa. I-GCr15: 179-207HB (88-94HRB), amanye angu-179-217HB (88-97HRB). Uma ubulukhuni bungafaneleki (buphezulu kakhulu, buphansi kakhulu noma obungalingani), izizathu kufanele zihlaziywe ngokucophelela, ezingase zithinte ukucima (njengobunzima obanele, i-decarburization, ukushisa ngokweqile, i-oval enkulu, njll.).

2. Ukucisha nokuqina kokuqina: lapho ukushuba kodonga kungengaphezu kuka-12mm, ngemva kokucisha, ≥63HRC, ngemva kokushisa, 60-65HRC; ingase ihlangabezane nezidingo ezikhethekile zobulukhuni zekhasimende, ezifana ne-61-64HRC, njll., kodwa ububanzi bokubekezelela ubulukhuni ngemva kokushisa Usayizi kufanele ube ngaphansi kuka-3HRC; ngesikhathi sokucisha okuvamile, ukubaluleka kokuqina kuncike kakhulu ekushiseni okushisayo.

3. Ukufana kokuqina: Izinga libeka ukuthi ukufana kokuqina kwengxenye efanayo ngokuvamile kungu-1HRC; lapho i-diameter yangaphandle inkulu kuno-200mm, ingu-2HRC uma ingekho ngaphezu kuka-400mm; uma inkulu kuno-400mm, ingu-3HRC.

Ukusebenza kokuqina okungafanelekile:

(1) Ukuqina okuphezulu: izinga lokushisa eliphezulu lokucisha noma isikhathi eside sokushisa, izinga lokupholisa elisheshayo, amandla aphezulu ekhabhoni (i-carburization).

(2) Ukuqina okuphansi: izinga lokushisa eliphansi lokucisha noma isikhathi esifushane sokushisisa, izinga lokupholisa elihamba kancane, amandla ekhabhoni ephansi (nge-decarburization), kanye nokususwa kwe-material decarburization.

(3) Ubulukhuni obungalingani: izinga lokushisa eliphansi lokucisha noma isikhathi esifushane sokushisisa, izinga lokupholisa elihamba kancane, ukususwa kwe-carburization yezinto ezibonakalayo, namathunzi okunamathela.
