Embodiment Construction
[0017] The implementation of the present invention will be further described in conjunction with the accompanying drawings:
[0018] Since the overall rare earth magnesium silicon ferrosilicon spheroidizer containing Mg10%, Si67%, RE1% has eliminated magnesium light during the smelting and pouring process of the nodulizer, and has reached a stable state, it is completely suitable for the spheroidization treatment temperature ≤ 1600 ℃ Therefore, it is of little significance to reduce the magnesium content; when the magnesium content needs to be reduced, the silicon content should be ensured to achieve a stable state where the nodulizer alloy liquid eliminates magnesium light during the smelting and pouring process.
[0019] The parts of the combined molten pool, except the outer frame 9 of the molten pool, the fastening bolts 10 and the fastening nuts 11, other components can be made of low carbon steel or heat-resistant cast iron.
[0020] Adjusting the spacing of the ribs 12 ...
