(1) face width of the one side aluminium alloy owing to spraying or topple over is necessarily less than the face width of cooling wheel disc, otherwise rises not
Effect to anticipation rapid solidification；On the other hand owing to, in cast cooling procedure, chill roll position and aluminium alloy are cast in
The position of cooling wheel disc is the most fixing, therefore when aluminium alloy is cast in chill roll, due to the impact of high temperature liquid stream, it is easy to
Make the position that in cooling wheel disc, aluminium alloy is poured into a mould produce abrasion, the cut of a circle circle occur, time serious, even produces hollow,
And cool down the position part that aluminium alloy in wheel disc do not pours into a mould and remain intact.It is uneven that this results in cooling wheel face quality, from
