Controller is installed, the controller is electrically connected with the rotary drive motor and lifting driving motor in the PLC control room
It connects, to control the rotation angle of rotating mechanism and the lifting position of elevating mechanism.
5. a kind of utilize a kind of work of the plunging spheroidization molten iron of the device of plunging spheroidization molten iron according to claim 2
Process, characterized by the following steps:
The elevating mechanism drives the leaching cage of the leaching bar assembly to be quickly pressed into the ladle of a nodularization station, and molten iron is from described
It soaks cage bottom portion to enter, contacts and react with the nodulizer in the accommodating space for being placed in the leaching cage, carry out spheroidising；
After the completion of spheroidising, the elevating mechanism drives the ladle soaked bar assembly and lift off the nodularization station；
The rotating mechanism driving leaching bar assembly and elevating mechanism turn to next nodularization station；
The elevating mechanism drives the leaching cage of the leaching bar assembly to be quickly pressed into the ladle of next nodularization station and completes nodularization
Processing, the elevating mechanism drive the ladle soaked bar assembly and lift off the nodularization station, the rotating mechanism driving
Leaching bar assembly and elevating mechanism turn to next nodularization station；
So circulation repeatedly, realizes the spheroidising of multiple nodularization stations.
6. a kind of process of plunging spheroidization molten iron according to claim 5, it is characterised in that: the nodularization station
It is set as 1 ~ 8.
7. a kind of process of plunging spheroidization molten iron according to claim 5, it is characterised in that: the nodulizer is
Magnesium ingot, magnesium slag or magnesium alloy.
8. a kind of process of plunging spheroidization molten iron according to claim 7, it is characterised in that: the magnesium ingot, magnesium
The magnesium content of slag or magnesium alloy is 90 ~ 99%.
9. a kind of process of plunging spheroidization molten iron according to claim 5, it is characterised in that: the elevating mechanism
The press-in speed for driving the leaching cage of the leaching bar assembly to be quickly pressed into the ladle of a nodularization station is 0.4 ~ 2.0m/s.
10. a kind of process of plunging spheroidization molten iron according to claim 5, it is characterised in that: the ladle
Molten iron level reserve molten iron splash space.
