Description
技术领域technical field
本实用新型涉及铝合金铸造升液管的技术领域，具体涉及一种用于铝合金低压铸造的钛酸铝升液管。The utility model relates to the technical field of an aluminum alloy casting liquid riser, in particular to an aluminum titanate liquid riser used for aluminum alloy low-pressure casting.
背景技术Background technique
目前铝合金低压铸造采用的升液管一般为铁质材料，在升液管使用过程中，高温下铁与熔融铝液发生反应，升液管容易发生溶蚀，并导致铝液增铁。为解决此类问题，现有实用新型专利CN202291362U升液管浸入铝液部分采用了碳化硅陶瓷管，实用新型专利CN204321159U升液管浸入铝液部分采用了石墨管，实用新型专利CN2675299Y升液管浸入铝液部分采用了石墨管，以上现有技术的共同特点是升液管由上管和下管两部分构成，上管为金属材料，下管为非金属材料，上管与下管之间采用螺纹连接。这种螺纹连接结构，在螺纹连接处存在缝隙，不利于升液管中铝液的平稳上升，而且由于毛细作用铝液容易进入缝隙并附着于升液管内壁，影响铝液在升液管中的流动，甚至容易导致升液管堵塞。即使现有技术在螺纹连接处采用了水玻璃密封，但效果并不理想。水玻璃与金属材料结合力不强，且膨胀系数差异较大，并不适于金属材料缝隙的密封，一般用于建筑材料的密封增强。由于水玻璃材料、上管金属材料与下管非金属材料的膨胀系数不一致，在升液管使用过程中，升液管需要不断地经受加热、冷却过程的循环考验，三种材料的膨胀收缩不一致容易在三种材料之间接触处产生应力。在螺纹连接处，水玻璃与上管或下管接触处容易沿接触面产生裂纹，影响升液管的正常使用。At present, the riser pipes used in aluminum alloy low-pressure casting are generally made of iron materials. During the use of the riser pipes, the iron reacts with the molten aluminum at high temperatures, and the riser pipes are prone to corrosion, which leads to the increase of iron in the aluminum liquid. In order to solve such problems, the existing utility model patent CN202291362U adopts a silicon carbide ceramic tube in the part of the rising liquid tube immersed in the aluminum liquid; the utility model patent CN204321159U adopts a graphite tube in the part of the rising liquid tube immersed in the aluminum liquid; The aluminum liquid part adopts graphite tube. The common feature of the above prior art is that the riser tube is composed of two parts, the upper tube and the lower tube. The upper tube is made of metal material, and the lower tube is made of non-metallic material. threaded connection. This threaded connection structure has a gap at the threaded connection, which is not conducive to the steady rise of the aluminum liquid in the riser, and due to capillary action, the aluminum liquid easily enters the gap and adheres to the inner wall of the riser, affecting the flow of the aluminum liquid in the riser The flow of the liquid may even easily lead to the clogging of the riser pipe. Even if the prior art has adopted water glass sealing at the threaded joint, the effect is not ideal. The combination of water glass and metal materials is not strong, and the expansion coefficient is quite different, so it is not suitable for sealing the gaps of metal materials, and is generally used for sealing enhancement of building materials. Due to the inconsistent expansion coefficients of the water glass material, the metal material of the upper tube, and the non-metallic material of the lower tube, during the use of the riser tube, the riser tube needs to be continuously tested by the heating and cooling process, and the expansion and contraction of the three materials are inconsistent. It is easy to generate stress at the contact between the three materials. At the threaded connection, the contact between the water glass and the upper or lower pipe is prone to cracks along the contact surface, which affects the normal use of the riser.
另外，非金属管的螺纹处由于螺纹齿宽度较小，承载能力较差，而且螺纹根部一般为尖角，在使用过程中螺纹被不断的加热、冷却，由于水玻璃材料、上管金属材料与下管非金属材料的膨胀系数不一致，螺纹根部容易产生热应力集中导致裂纹萌生，甚至造成螺纹破坏，使这种螺纹连接结构的升液管寿命受到影响。In addition, the threads of non-metallic pipes have poor load-carrying capacity due to the small thread tooth width, and the thread roots are generally sharp angles. During use, the threads are continuously heated and cooled. The expansion coefficient of the non-metallic material of the lower pipe is inconsistent, and the root of the thread is prone to thermal stress concentration, leading to crack initiation, and even thread damage, which affects the life of the riser pipe with this threaded connection structure.
以上现有技术由上管与下管通过螺纹连接制成的升液管在使用过程中，铝液升至上管（金属管）部分时，仍然要与铁质材料接触，容易与铁质材料反应导致铝液增铁。In the prior art above, the riser pipe made of the upper pipe and the lower pipe through threaded connection is in use. When the aluminum liquid rises to the upper pipe (metal pipe), it still needs to be in contact with the iron material, and it is easy to react with the iron material. Lead to the increase of iron in molten aluminum.
