Umahluko phakathi kwefrikhwensi ephezulu kunye ne-medium frequency quenching in izixhobo zokucima rhoqo

(1) Ukucima i-high-frequency quenching inomaleko olukhuni ongekho nzulu (1.5 ~ 2mm), ukuqina okuphezulu, i-workpiece ayilula ukuba i-oxidize, inokuguqulwa okuncinci, umgangatho wokucima okulungileyo kunye nokusebenza kakuhle kwemveliso, kwaye ifanelekile kwiindawo ezisebenza phantsi kwengxabano. iimeko, ezifana iigiya ezincinane ngokubanzi, Shafts (izinto ezisetyenziswayo 45 # steel, 40Cr);

2 intsimbi, i-3Cr, i-5Mn45V kunye nentsimbi ye-ductile) .

Ngokwe-frequency yangoku, i-induction yokufudumeza indawo yokucima indawo inokwahlulwa ibe: ukucima i-frequency ephezulu 100-1000kHz. I-intermediate frequency quenching 1-10kHz. Amandla ombane acima i-50Hz.

1. Ubunzima bomgangatho ophezulu yi-2-3HRC ephezulu kunokucima okuqhelekileyo, kwaye ine-brittleness ephantsi, amandla okudinwa, kunye nokuqina kwempembelelo. Ngokuqhelekileyo, i-workpiece inokunyuswa ngama-20-30%.

2. I-deformation incinci, kwaye ubunzulu bomgca wokucima kulula ukulawula.

3. Intsimbi ephantsi yokuqina ephantsi ingasetyenziswa, ukusebenza kulula ukuyiqonda i-mechanization kunye ne-automation, imveliso iphezulu, iphezulu i-frequency yangoku, i-thinner layerable layer.

(5) Isixhobo sokucima amaza ombane aphezulu ngokuqhelekileyo siyi-1-2mm, ukucinywa kwamatyeli aphakathi ngokuqhelekileyo yi-3-5mm, kwaye ukucinywa kwamaza ombane kunokufikelela>=10-15mm.

(6) Ukufudumala kwe-high-frequency induction heat: i-frequency yangoku yi-100-500 kHz (kHz), kunye nobunzulu bokuqina obusebenzayo ngu-0.5-2 mm (mm). Isetyenziswa ikakhulu kumacandelo amancinci naphakathi afuna umaleko oqinileyo oqinileyo, onje ngeegiya ezincinci zeModular, iishafti ezincinci neziphakathi, njl.

(7) I-intermediate frequency induction heat: i-frequency yangoku yi-500 ukuya kwi-10000 Hz (Hz), kunye nobunzulu bokuqina obusebenzayo yi-2 ukuya kwi-10 mm (mm). Isetyenziswa ikakhulu kumacandelo afuna umaleko oqinileyo oqinileyo, onje ngeegiya ezinemodyuli ephakathi, iigiya zemodyuli ezinkulu, iishafu ezinobubanzi obukhulu, njl.
