Aluminium-silicon alloy rolling system

The utility model discloses an aluminium-silicon alloy rolling system. Aluminium-silicon alloy consists of thick and big plate-shaped silicon crystal grains and an aluminum substrate. Complex plastic deformation happens in a hot rolling process during ingot casting. Because the silicon crystal grains play a role in cutting the aluminum substrate apart, a crack phenomenon happens to edges of a strip. Through further processing, a defect of cracks is generated on the strip, thereby limiting the development of the aluminium-silicon alloy. The system provided by the utility model comprises a rolling sub-system A (6) which consists of a heating furnace 1, a conveying belt 2, and a rolling mill 4. The heating furnace is connected with a roller 3 of the rolling mill 4 through the conveying belt 2. The system provided by the utility model is used for the rolling of the aluminium-silicon alloy.
