Horizontal casting equipment for aluminium alloy flat ingot

[0015] Specific implementation plan

[0016] In this example, 12 crystallizers are arranged on the same mold table. The bottom of the mold table corresponds to each crystallizer with a starter head mounted on the starter seat, and the upper part of each mold is made of refractory and heat-insulating material, and The hot top 10 with a recessed splitter plate 8 has a flat cross-section of the mold, and the bottom of the hot top splitter tray is evenly provided with two split holes 11 corresponding to the longitudinal length of each flat mold. The split holes are upper and lower Large trumpet shape, this shape is more conducive to diversion.

[0017] The cooling water slit 12 on the flat crystallizer in this example is that the width of the longitudinal cooling water slit is greater than the width of the transverse cooling water slit, and its width ratio is 4/3:1. This is because the longitudinal sidewall of the slab is longer than the transverse sidewall. If the width of the horizontal cooling water gap is the same, the cooling rate of the longitudinal side wall of the slab will be lower than the cooling rate of the lateral side wall, which will affect the quality of the ingot. Therefore, providing more cooling water on the longitudinal outer wall can make the slab cross-sectional periphery The cooling rate at the place tends to be the same.

[0018] In this example, an annular graphite ring lining 9 is provided at the opening on the inner wall of the crystallizer, which can further improve the surface quality of the ingot.

[0019] According to the present invention, more than 3 shunt holes can be arranged at the bottom of the shunt plate corresponding to each crystallizer according to the shape of the cross-section of the crystallizer.
