Problems solved by technology

The disadvantage of this kind of process equipment is that it cannot control the level of the metal liquid level in the DC crystallizer well. If the liquid level is too low, it will cause a cold barrier on the surface of the ingot, and in serious cases, aluminum leakage will occur. The depth of the surface deflection is very easy to cause the surface of the ingot to be scratched and cracked
However, this process cannot be directly used to produce slabs, because the longitudinal length of slabs i

Example Embodiment

[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 horizo...

Abstract

The present invention includes a crystallizer mounted on the dummy head on the dummy seat, the upper portion of crystallizer is equipped with flow distribution plate which can possess hot top action. It is characterized by that the bottom portion of the described flow distribution plate is equipped with more than two fow-distributing holes correspondent to every crystallizer. The adoption of said invented equipment can produce aluminium alloy flat ingot, can solve the flow equalization problem in the course of casting process, the cast aluminium ingot does not produce crack, so that the same-level hot top casting process can be adopted in the production of aluminium alloy flat ingot.

Description

technical field [0001] The invention belongs to a hot-top casting device for casting aluminum alloy flat ingots, and is also suitable for casting other ingots with complex geometric shapes. Background technique [0002] The equipment used in the traditional direct cooling (DC) casting process such as figure 1 As shown, a flow plate 1 and a splitter funnel 3 are provided on the upper part of the crystallizer 4 installed on the mold table, and a dummy head mounted on the dummy seat is provided on the lower part of the crystallizer. Before casting, the mold table and the dummy seat are placed Install the casting well, lift the dummy head up, and make it extend into the crystallizer to form a complete casting mold. When casting, the metal aluminum liquid flows into the mold from the split funnel, and is cooled by cooling water. The dummy head is cast toward the mold at a certain speed Move down the well, pull out the cooled and formed aluminum ingot in the crystallizer, stop su...
