High-frequency heat treatment process yestainless simbi mapanga ekicheni anodzimwa ne yepamusoro-frequency kudzima michina

Izvo zvinhu zvesimbi isina tsvina yekicheni banga ndeye 3Cr13 kana 4Cr13, uye yekunze dimension ndeye 180mmX80mmX2.5mm. Mushure mekugaya kwakashata kusvika ku 0.8-0.9mm, iyo yekucheka inoiswa pasi peiyo induction quenching kupisa kurapwa mune yakakwirira-frequency yekudzima muchoto. Mushure mekudzima, inosangana nezvinodiwa zvinotevera: kuoma 50-56HRC, nzvimbo yakaoma ≥25mm, yunifomu yakaoma kugovera, uye deformation ≤2mm.

1) Magetsi parameters yechigadzirwa. Mhepo inopinza ndeye 380V, anode voltage i7.5kV, anode current i2.5A, tank voltage 5kV, grid current 0.6A, uye frequency i250kHz.

2) Kudzima nzira yekudziya. High-frequency quenching furnace inoshandiswa pakudzima. Inductor yakakosha inofanira kugadzirwa. Iyo kicheni banga inofanira kuiswa munzvimbo yakakodzera muinductor. Iyo induction yekudziya yekumhanyisa inowanzo 200-400 ℃/s. Austenitization inopedzwa nekukasira, uye hapana kuchengetedza kupisa kunodiwa. . Kudzima tembiricha yekudziya ndeye 1050-1100 ℃, uye inotonhodza imafuta. Kupisa pa200-220 ℃.

Mukati meiyo 180mm X25mm munzvimbo yakaomeswa, kuomarara mushure mekudzima uye kupisa zvese> 50HRC, uye kuoma kwacho kwakafanana. Zviratidzo zvese zvinogona kusangana nezvinodiwa zvehunyanzvi.
