A connecting frame 1802 is installed between the two lifting frames 1801.

[0051] An air inlet graphite ring 7 and an oil inlet graphite ring 6 are installed inside the outer membrane to effectively prevent aluminum liquid from directly contacting the crystallizer and damaging the crystallizer.

[0052] The oil inlet graphite ring 6 is connected to lubricating oil, and the air inlet graphite ring 7 is connected to inert gas. The combined use can form an oil film on the inner surface to prevent aluminum water from condensing on the crystallizer and improve the smoothness of the outer surface of the aluminum rod.

[0053] The hot top 3 is fixed on the outer mold 8 through the upper clamping ring 4 and the lower clamping ring 5. The molten aluminum flows directly from the top surface of the through hole 301 of the hot top 3 and crystallizes on the columnar mold formed by the ingot starter body 2 and the graphite ring ( Figure 5 is the initial position of the starter head body 2), and as the aluminum liquid continues to increase, the starter head body 2 slowly descends to form a cylindrical aluminum rod.

[0054] A water ring mold 10 is installed inside the lower part of the outer mold 8. The cooling water outside the crystallizer enters the inner side of the crystallizer through the water inlet hole 9, and forms a water curtain below the crystallization position of the aluminum rod through the water ring mold 10 to further cool the aluminum rod.

[0055] The ingot starter body 2 is used to carry the aluminum rod, and there are four guide heads on the outer circumference for precise mold closing of the equipment.

[0056] In actual use:

[0057] The bottom of the ingot starter lifting platform 18 of the present invention is equipped with an oil cylinder for driving it to rise or fall. When the ingot starter body 2 needs to work with the crystallization head 1, the oil cylinder drives the entire ingot starter lifting platform 18 to rise, so that each ingot starter body 2 extends into the crystallization head 1.

[0058] The initial positions of the single crystallization head 1 and the ingot starter head body 2 during operation are shown in FIG. Figure 5 , molten aluminum is fed in from the through hole 301 of the hot top 3, and the molten aluminum enters the molding area between the crystallization head 1 and the ingot head body 2 from the through hole 301. The molten aluminum slowly solidifies to form an aluminum shell. Under the action of the external oil cylinder, the ingot head body 2 is controlled to move slowly and gradually downward, that is, the oil cylinder is driven to work, and the entire ingot head lifting platform 18 is controlled to descend, thereby forming a cylindrical aluminum rod. In this molding process, the oil inlet graphite ring 6 is cooled by oil, the air inlet graphite ring 7 is cooled by air, and the water inlet hole 9 is passed with cooling water, and cooling is performed synchronously, with good cooling effect and good molding effect. When the aluminum rod is molded to the required height, stop feeding molten aluminum and take away the aluminum rod. The same method as above can be used to carry out the next cycle.
