There is a splitter plate that can also function as a hot top, and it is characterized in that: the bottom of the splitter plate is provided with no less than two splitter holes corresponding to each crystallizer, and the device is used to produce aluminum alloy flat ingots, which can solve the problem of casting process.

Description
本发明属一种用于铸造铝合金扁铸锭的热顶铸造装置，也适用于铸造其它几何形状复杂的铸锭。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.
传统的直冷(DC)铸造工艺所用设备如图1所示，在装于模台上的结晶器(4)上部设有流盘(1)和分流漏斗(3)，结晶器下部设有装在引锭座上的引锭头，铸造前，把模台、引锭座安上铸造井，将引锭头升上来，使其伸入结晶器内形成完整的铸模，铸造时，金属铝液从分流漏斗流入结晶器，通冷却水冷却，引锭头以一定速度向铸造井下方移动，将结晶器内冷却成形的铝锭拉出，达到一定长度停止供铝液和冷却水，翻开模台吊出铸锭。这种工艺设备不足之处是不能很好地控制DC结晶器内金属液面的水平，液面过低会造成铸锭表面形成冷隔，严重时会产生漏铝，过高又会加重铸锭表面偏折瘤的深度，极易造成铸锭表面拉痕、拉裂。目前采用同水平热顶铸造工艺可以解决这类问题，热顶铸造工艺所用的铸造设备如图3所示：即在结晶器(4)上开口处设有用耐火绝热材料制成的的热顶(10)，热顶上设有凹下的分流盘(8)，分流盘底部对应每个结晶器内腔中心部位设有一个分流孔(11)，有了热顶以后，结晶器内金属液面的水平就很容易控制，所以同水平热顶铸造工艺生产的铸锭内部质量好，整个铸锭组织均匀，机械性能好，铸锭表面光滑，而且由于热顶铸造取消了漏斗，从而一方面可铸造规格更为细小的铸锭，另一方面简化了工艺，提高了生产效率。但该工艺不能直接用于生产扁锭，因为扁锭的纵向长度大于横向宽度，在传统直冷铸造中，生产扁锭要在直冷结晶器里放一个能纵向均布液流的船形分流漏斗(3)，才能铸出没有裂纹的铸锭，而在同水平热顶铸造工艺装置里不能放置分流漏斗，所以目前的铝合金扁锭铸造还是只能采用传统的直冷工艺。The equipment used in the traditional direct cooling (DC) casting process is shown in Figure 1. A flow plate (1) and a splitter funnel (3) are arranged on the upper part of the crystallizer (4) mounted on the mold table, and a device is installed on the lower part of the crystallizer. The dummy head on the dummy seat, before casting, install the mold platform and the dummy seat on the casting well, lift the dummy head up, and make it extend into the crystallizer to form a complete casting mold. During casting, the metal aluminum liquid It flows into the crystallizer from the splitter funnel and is cooled by cooling water. The dummy head moves to the bottom of the casting well at a certain speed, and pulls out the aluminum ingot cooled and formed in the crystallizer, and stops supplying aluminum liquid and cooling water when it reaches a certain length, and opens the mold. The table lifts out the ingot. 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 can easily cause the surface of the ingot to be scratched and cracked. At present, the same level hot top casting process can solve this type of problem. The casting equipment used in the hot top casting process is as shown in Figure 3: that is, a hot top ( 10), there is a concave diverter plate (8) on the hot top, and a diverter hole (11) is provided at the bottom of the diverter plate corresponding to the center of each crystallizer cavity. After the hot top is installed, the metal liquid level in the crystallizer Therefore, the internal quality of the ingot produced by the same level hot top casting process is good, the whole ingot structure is uniform, the mechanical properties are good, and the surface of the ingot is smooth. Casting ingots with smaller specifications, on the other hand, simplifies the process and improves production efficiency. However, this process cannot be directly used to produce slabs, because the longitudinal length of slabs is greater than the transverse width. In traditional direct cooling casting, a boat-shaped split funnel that can distribute liquid flow longitudinally and evenly in the direct cooling crystallizer should be placed in the direct cooling crystallizer to produce slabs. (3) Only ingots without cracks can be cast, and the diverter funnel cannot be placed in the same level hot top casting process device, so the current aluminum alloy flat ingot casting can only use the traditional direct cooling process.
本发明旨在提供一种不设分流漏斗也能对金属铝液有均流作用、从而可生产出合格扁锭的铝合金扁铸锭同水平热顶铸造装置。The present invention aims to provide an aluminum alloy slab ingot same-level hot top casting device which can evenly flow metal aluminum liquid without setting a diverting funnel, so that qualified slabs can be produced.
实现上述目的的技术方案是(结合实施例图5、6)：本发明包括结晶器(4)，结晶器下部对应设有装在引锭座上的引锭头，结晶器上方设有用耐火绝热材料制成、兼起热顶作用的分流盘(8)，分流盘底部设有与结晶器内腔相通的分流孔(11)，其特征在于：所述的分流盘(8)底部对应每个结晶器内腔设有不少于两个的分流孔(11)。The technical scheme for realizing the above-mentioned purpose is (in conjunction with embodiment Fig. 5,6): the present invention comprises crystallizer (4), and the crystallizer bottom is correspondingly provided with the dummy head that is contained on the dummy seat, and above the crystallizer is provided with refractory heat insulation A splitter plate (8) made of high-quality materials that also acts as a hot top, the bottom of the splitter plate is provided with a splitter hole (11) that communicates with the inner cavity of the crystallizer, and it is characterized in that: the bottom of the splitter plate (8) corresponds to each The inner cavity of the crystallizer is provided with not less than two distribution holes (11).
本发明在兼起热项作用的分流盘底部对应每个结晶器内腔设置两个或两个以上分流孔，改变了以往同水平热顶铸造工艺装置分流盘对应每个结晶器内腔只在中心部位设置一个中心分流孔的结构，这样可根据铸锭的几何形状均匀设置分流孔，达到平均分配金属液流的目的，本发明既利用了同水平热顶铸造工艺的优点，又解决了用该工艺生产铝合金扁铸锭的均流问题，采用本装置铸造铝合金扁锭时，结晶器内液穴不会很深，液穴形状好，铸出的扁锭既具有现有技术中同水平热顶铸造铸锭的所有优点，又不易出现裂纹，同时还可用于铸造其它几何形状复杂的铸锭。In the present invention, two or more diversion holes are arranged at the bottom of the diverter plate which also acts as a heat term, corresponding to each inner cavity of the crystallizer, which changes that the diverter plate corresponding to each inner cavity of the crystallizer in the same level hot top casting process device in the past only The central part is provided with a structure of a central split hole, so that the split holes can be evenly arranged according to the geometric shape of the ingot to achieve the purpose of evenly distributing the metal liquid flow. The problem of current equalization in the production of aluminum alloy flat ingots by this process, when using this device to cast aluminum alloy flat ingots, the liquid pockets in the crystallizer will not be very deep, the shape of the liquid pockets is good, and the cast flat ingots have the same characteristics as those in the prior art. All the advantages of horizontal hot top casting ingots, but less prone to cracks, and can also be used to cast other ingots with complex geometries.

实施例说明：Example Description:
本例将12支结晶器排列设在同一模台上，模台下方对应每一结晶器设有装在引锭座上的引锭头，每一结晶器上部设有用耐火绝热材料制成，并带有凹下的分流盘8的热顶10，结晶器的横截面为扁形，热顶分流盘底部在对应每个扁形结晶器纵向长度方向均匀设置两个分流孔11，分流孔为上小下大的喇叭形，这种形状更利于分流。In this example, 12 crystallizers are arranged on the same mold platform, and each crystallizer is provided with a dummy head installed on the dummy seat corresponding to each crystallizer under the mold platform. The hot top 10 with a concave splitter plate 8, the cross section of the crystallizer is flat, and the bottom of the hot top splitter plate is evenly provided with two split holes 11 corresponding to the longitudinal length of each flat crystallizer, and the split holes are upper and lower. Large trumpet shape, this shape is more conducive to diversion.
本例扁形结晶器上的冷却水缝12为纵向冷却水缝宽度大于横向冷却水缝宽度，其宽度比为4/3∶1，这是因为扁锭纵向侧壁长于横向侧壁，如果纵、横向冷却水缝宽度一样宽，扁锭纵向侧壁冷却速度就会小于横向侧壁的冷却速度，影响铸锭质量，所以在纵向外壁上提供更多的冷却水可使扁锭横截面周边上各处的冷却速度趋于一致。The cooling water slot 12 on the flat crystallizer of this example is that the longitudinal cooling water slot width is greater than the transverse cooling water slot width, and its width ratio is 4/3: 1. This is because the longitudinal side wall of the flat ingot is longer than the horizontal side wall. If the width of the transverse cooling water gap is the same, the cooling rate of the longitudinal side wall of the slab will be lower than that of the transverse 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-section peripheral The cooling rate tends to be the same.
本例在结晶器内壁上开口处设有环形石墨环衬里9，可进一步提高铸锭表面质量。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.
本发明也可根据结晶器横截面的形状在对应每个结晶器的分流盘底部设置3个以上的分流孔。In the present invention, according to the shape of the cross-section of the crystallizer, more than three distribution holes can be arranged at the bottom of the distribution plate corresponding to each crystallizer.
