Aluminum melt in lattice semi-continuous casting production process plays stirring action, can play homogeneous temperature field, at the uniform velocity distribution and it is not dirty
Contaminate the effect of aluminium alloy melt, still, this method due to alternating magnetic field skin effect, to the active force of aluminium alloy melt by outer
Inwardly gradually weaken, surface is most strong, and center portion is most weak, and stirring capacity is limited, cause during the ingot casting of big specification, ingot casting it is interior
The crystallization condition in portion hardly results in improvement；In the prior art there are also a kind of super large-scale aluminium alloy ingot casting preparation facilities and method,
Melt treatment device is inserted into inside heat top or crystallizer center insertion melt during hot top formula semi-continuous casting, it is right
Alloy melt applies electromagnetic field from inside and forces cooling, accelerates heat transfer and the mass transfer of super large-scale inside ingot melt, still,
Melt treatment device melt regions below are not by electromagnetic field effect, also, forced cooler setting is in the close knot in molten bath
Crystal zone forward position position, be easy to cause temperature relatively low, and preferentially forming core crystallizes to form mass defect on cooler, exists simultaneously and freezes
Danger.
