Habka daaweynta kulaylka-sare ee loogu talagalay mindiyaha jikada ee birta ah ee ay demisay aaladaha bakhtiinta ee soo noqnoqda

Qalabka mindida birta ah ee birta ah waa 3Cr13 ama 4Cr13, cabbirka dibaddana waa 180mmX80mmX2.5mm. Ka dib markii la shiiday qallafsanaanta 0.8-0.9mm, cidhifka goynta ayaa lagu sakhiray daawaynta kulaylka deminta induction ee foorno demisay oo aad u sarreeya. Deminta ka dib, waxay buuxinaysaa shuruudaha soo socda: engegnaanta 50-56HRC, aagga engegan ≥25mm, qaybinta engegnaanta lebbiska, iyo qallooca ≤2mm.

1) Qalabka korantada ee qalabka. Qulqulluu 380V, 7.5kV, 2.5A, fi 5kV, 0.6A, fi 250k Hz;

2) Deminta habka kuleylka. Foornada deminta ee soo noqnoqota ee ugu sarreysa ayaa loo isticmaalaa deminta. Inductor gaar ah waa in la qaabeeyaa. Mindida jikada waa in la dhigaa meel ku haboon inductor-ka. Xawaaraha kulaylinta induction guud ahaan waa 200-400 ℃/s. Aqoonsiga waxa lagu dhammeeyaa isla markiiba, wax ilaalin kulayl ahna looma baahna. . Heerkulka kuleyliyaha deminta waa 1050-1100 ℃, qaboojiyahana waa saliid. Heerkulka heerkulka 200-220 ℃.

Inta u dhaxaysa 180mm X25mm ee aagga engegan, engegnaanta ka dib deminta iyo xanaaqa waa dhammaan> 50HRC, iyo engegnaanta waa labbis. Dhammaan tilmaamayaasha waxay buuxin karaan shuruudaha farsamada.
