Aluminium bus vertical casting technology method

The present invention relates to a technical method for vertical casting of aluminum bus. By adopting the technique of vertical casting the invention is characterzied in that the technological parameters in production are as follows: 1) aluminum content in aluminum liquid used in casting is more than 99.65 percent, content of impurity is less than 0.35 percent, and ratio of Fe to Si is limited between 1.2 to 1.5; 2) casting termperature is limited between 720 to 730 DEG C; 3) casting speed is controlled between 80 to 100mm per minute; 4) the distant between level of the aluminum liquid and the upper inner rim of crystallizer is 2.0cm. The present method can remarkably improve the passing rate of product. In practical production, the present method can control heat crack, curve and twist of the aluminum bus and can reduce the production cost of the aluminum bus.
