Ƙarfafa ƙora process debugging precautions

(1) Daidaita ikon zuwa mafi ƙanƙanta kafin cire kuskure.

(2) A lokacin debugging, kayan aikin yakamata suyi zafi a ƙarƙashin yanayin sanyaya kuma lokacin dumama bai yi tsayi ba.

(3) The heating temperature of induction quenching is 50-100°C higher than the heating temperature in the material furnace.

(4) Workpieces that need to be tempered in a furnace: 1) Workpieces with complex economical shapes of alloy steel should be tempered in time for 2-3 hours. 2) Carbon steel and workpieces with simple shapes should be tempered in time within 4 hours.

(5) Residual temperature should be left after the quenched workpiece leaves the cooling condition: 1) The shape is complex and the alloy steel should have a residual temperature of about 200 °C. 2) Small pieces have a residual temperature of 120°C. 3) Large pieces have a residual temperature of 150°C.
