Detailed Description
As shown in figure 1, in the wire feeding inoculation process, when a casting furnace is used for casting, an inoculation line 10 is added into a molten iron outlet 9 of the casting furnace, and the weight of the inoculation line 10 added is 0.1-0.3% of the weight of molten iron to be cast in a casting furnace 11. Different inoculation line adding proportions are set for different products by accurately controlling the amount of the inoculation line, so that the casting requirements of different products can be met.
The time length of the inoculation line added by the wire feeding device is 1 to 4 seconds more than the casting time. The wire feeding inoculation process further comprises the step of driving the heat-resistant guide pipe to rotate through the deflection driving device of the wire feeding device after the inoculation wire is added, so that the lower end of the heat-resistant guide pipe swings upwards, and the tail end of the inoculation wire is far away from the molten iron outlet.
In the rotating process of the heat-resistant guide pipe, namely the upward swinging process of the lower end of the heat-resistant guide pipe, the movable heat-resistant sleeve of the wire feeding device moves downwards and is sleeved outside the tail end of the inoculation wire extending out of the heat-resistant guide pipe, so that the inoculation wire is prevented from entering molten iron when the operation is not carried out.
When the casting furnace is used for casting, the inoculation line is added, the weight of the inoculation line is 0.17% of the weight of molten iron to be cast in the casting furnace, and the casting method is suitable for casting of the flywheel, the oil pan and the belt pulley. The weight of the inoculation line added can also be 0.1%, 0.15%, 0.21% or 0.3% of the weight of molten iron to be cast in the casting furnace, so that the method is suitable for casting of other different products.
And when the inoculation line is added, the depth of the molten iron to be cast in the casting furnace is more than half of the depth of the casting furnace.
When the inoculation line is added, the depth of molten iron to be cast in the casting furnace is two thirds of the depth of the casting furnace.

The inoculation line can be added completely by enabling the lower end of the heat-resistant guide pipe to deflect upwards, so that the inoculation line is prevented from contacting molten iron. The accuracy of the addition of the inoculation line is ensured.
As shown in fig. 2 and 3, the lower pot head of heat-resisting pipe has heat-resisting sleeve 5 of activity, fixed mounting has on the heat-resisting sleeve 5 of activity along guide arm 6 that heat-resisting pipe 3's axis direction extends, fixed mounting has driving gear 7 on the pivot 4, rotate on the frame and install first driven gear 8 and second driven gear 12, first driven gear 8 with driving gear 7 intermeshing, second driven gear with first driven gear meshing, fixed mounting has swinging arms 13 on the terminal surface of second driven gear 12, rotate on the guide arm 6 install with swinging arms 13 complex runner 16.
When the rotation shaft is deflected counterclockwise in this embodiment, as shown in fig. 3, the heat-resistant guide duct is deflected counterclockwise along with the rotation shaft, the height of the lower end of the heat-resistant guide duct is increased, thereby being far away from the molten iron outlet of the casting furnace, the driving gear rotates along with the rotating shaft anticlockwise, the first driven gear 8 rotates clockwise, the second driven gear 12 rotates anticlockwise, so that the oscillating rod swings anticlockwise, acts on the rotating wheel 16 in the swinging process, pushes the guide rod to move through the rotating wheel, thereby driving the movable heat-resistant sleeve 5 to protrude from the end of the heat-resistant pipe, which, when the heat-resistant pipe 3 is deflected anticlockwise, causes the height of the lower end of the heat-resistant pipe 3 to increase, in the process, the movable heat-resistant sleeve 5 moves downwards and is sleeved outside the inoculation line 10 extending out of the heat-resistant conduit, so that the inoculation line is prevented from entering molten iron when the operation is not carried out.
