[0027] The outer surfaces of the poke rod 141, the poke plate 142 and the poke cone 143 are all provided with an anti-sticking coating, and the anti-sticking coating can prevent the poke rod 141, the poke plate 142 and the poke cone 143 from adhering to a large amount of casting solution when they are extended into the casting solution.

During the rotation of the heat preservation box 1, the centrifugal force can assist the solution to be evenly distributed in the casting mold 2, so that the gas can be better discharged from the solution; Step 6: During the vibration, lifting and rotation of the rotating platform 7, the third hydraulic cylinder 136 can be started to make the poke rod 141 drive the poke plate 142 and the poke cone 143 to move downward and extend into the casting pipe 3.
