Inkqubo yonyango lobushushu obuphezulu kwiimela zekhitshi zentsimbi engenasici ezicinywa yi izixhobo ezikhawulezayo zokucima izixhobo

Izinto eziphathekayo zentsimbi ekhitshini imela yi-3Cr13 okanye i-4Cr13, kwaye i-dimension yangaphandle yi-180mmX80mmX2.5mm. Emva kokusila ngokukrakra ukuya kwi-0.8-0.9mm, umgca wokusika uxhomekeke kwi-induction yokucima unyango lobushushu kwisithando somlilo esiphezulu sokucima. Emva kokucima, ihlangabezana nezi mfuno zilandelayo: ubunzima be-50-56HRC, indawo enzima ≥25mm, ukusabalalisa ubunzima obufanayo, kunye ne-deformation ≤2mm.

1) Iiparamitha zombane zesixhobo. I-voltage yegalelo yi-380V, i-anode voltage yi-7.5kV, i-anode current yi-2.5A, i-tank voltage yi-5kV, i-grid yangoku yi-0.6A, kunye ne-frequency yi-250kHz.

2) Ukucima inkqubo yokufudumala. Iziko lokucima i-high-frequency quenching lisetyenziselwa ukucima. I-inductor ekhethekileyo kufuneka yenziwe. Ummese wekhitshi kufuneka ubekwe kwindawo efanelekileyo kwi-inductor. Isantya sokufudumeza induction ngokuqhelekileyo yi-200-400 ℃/s. I-Austenitization igqitywe ngephanyazo, kwaye akukho kugcinwa kobushushu obufunekayo. . Ukucima ubushushu bokufudumala yi-1050-1100 ℃, kwaye into epholileyo yioli. Ubushushu kwi-200-220 ℃.

Ngaphakathi koluhlu lwe-180mm X25mm kwindawo eqinile, ukuqina emva kokucima kunye nokufudumala konke> 50HRC, kwaye ubunzima bufana ngokufanayo. Zonke izalathisi zinokuhlangabezana neemfuno zobugcisa.
