High-frequency cua sov txheej txheem rau stainless hlau chav ua noj riam quenched los ntawm high-frequency quenching khoom
High-frequency tshav kub kho txheej txheem rau stainless hlau chav ua noj riam quenched los ntawm cov khoom siv ntau zaus
Cov khoom ntawm stainless hlau chav ua noj riam yog 3Cr13 los yog 4Cr13, thiab sab nraud dimension yog 180mmX80mmX2.5mm. Tom qab sib tsoo ntxhib mus rau 0.8-0.9mm, txiav ntug yog raug rau induction quenching cua sov kho nyob rau hauv ib tug high-frequency quenching rauv. Tom qab quenching, nws ua tau raws li cov cai hauv qab no: hardness 50-56HRC, hardened cheeb tsam ≥25mm, uniform hardness faib, thiab deformation ≤2mm.
1) Kev ntsuas hluav taws xob ntawm lub cuab yeej. Lub input voltage yog 380V, lub anode voltage yog 7.5kV, lub anode tam sim no yog 2.5A, lub tank voltage yog 5kV, daim phiaj tam sim no yog 0.6A, thiab zaus yog 250kHz.
2) quenching cua sov txheej txheem. High-frequency quenching rauv yog siv rau quenching. Ib tug tshwj xeeb inductor yuav tsum tau tsim. Cov riam hauv chav ua noj yuav tsum muab tso rau hauv qhov chaw tsim nyog hauv inductor. Lub induction cua sov ceev yog feem ntau 200-400 ℃ / s. Austenitization tiav nyob rau hauv ib qho instant, thiab tsis tas yuav tsum tau khaws cia kub. . Lub quenching cua sov yog 1050-1100 ℃, thiab cov coolant yog roj. Kub ntawm 200-220 ℃.
Nyob rau hauv qhov ntau ntawm 180mm X25mm nyob rau hauv lub hardened cheeb tsam, lub hardness tom qab quenching thiab tempering yog tag nrho> 50HRC, thiab cov hardness kuj zoo ib yam. Txhua qhov ntsuas tuaj yeem ua tau raws li qhov yuav tsum tau ua.
