(1) The theory of self shrinkage is used to improve the hole filling rate of Flywheel Casting.
(2) In the production of iron mold sand coated casting of Flywheel Casting, the reasonable layout of sprue in gating system is helpful to improve the distribution of temperature field. The shape, size and distribution of hot spot of flywheel casting are simulated and calculated by MAGMAsoft software, which can provide an intuitive and reliable basis for the process design of iron mold sand coated casting.
(3) In the process design of iron mold sand coated casting of Flywheel Casting, we should not only consider the reasonable distribution of temperature field, but also pay great attention to the rationality of molten iron flow field. In this way, it can be ensured that in the process of pouring and filling, in the process of rapid filling, the flow of molten iron will not produce eddy current as much as possible, and the filling will be fast and stable; The eddy current in the molten iron or molten iron in the casting system can be eliminated as soon as possible, so as to ensure that the molten iron in the casting system can be filled with molten iron calmly.
