14ommon problems of smelting molten iron in induction furnace

1.Burning loss of Si, Mn, Cr and other oxidizable elements in induction furnace

2 Induction furnace has no cupola oxidation atmosphere

3 Temperature of molten iron in induction furnace exceeds equilibrium temperature

4 After the castings were machined, cracks were found

5 The inoculation effect of gray cast iron is not good

6 The spheroidization degree of ductile iron fluctuates greatly

7 The number of graphite balls is less and the size of the balls is not uniform

8 Poor cutting performance of casting

9 Spectral analysis showed that the residual Mg content was more than 0.06%, but the casting was not blank

10 Ductile iron has low impact toughness

11 There is an unknown cause

12 Induction furnace smelting time is long, power consumption is high

13 There is a continual glitch in Induction furnace

14 The elephant foot
