Description

Technical Field

[0001] This utility model relates to the field of graphite riser technology for electrofused bricks, and in particular to a graphite riser for electrofused bricks that is not easily contaminated. Background Technology

[0002] A non-contamination-resistant graphite riser for fused metal bricks is a key device meticulously developed and designed to address the numerous challenges faced in the production of fused metal bricks, particularly the cleaning difficulties associated with traditional graphite risers. In the fused metal brick production process, the riser plays a crucial role; its performance directly impacts product quality and production efficiency.

[0003] Currently, when casting graphite risers for electrofused bricks, molten metal is directly poured into the riser. Simply tilt the ladle containing the molten metal and let the molten metal flow into the riser by gravity. This method requires relatively low skill from the operators and is easy to learn.

[0004] While pouring molten metal directly into the riser is convenient and quick, the lack of precise flow rate and direction control during the pouring process means that if the ladle is tilted at too large an angle or the initial flow rate of the molten metal is too high, the molten metal will impact the inner wall of the riser with considerable force. This not only causes molten metal to splash, but the splashed molten metal also quickly adheres to the outer surface of the riser. Therefore, a non-contamination-prone electrofused brick graphite riser is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electrofused brick graphite riser that is not easily contaminated, aiming to improve the problem that the prior art cannot effectively prevent molten metal from splashing onto the outer surface of the riser.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of this utility model is provided: a graphite riser for electrofused bricks that is not easily contaminated, comprising a graphite riser body 1, a funnel connecting block 2 and a base sealing block 3. Ventilation and cooling components are provided inside both the funnel connecting block 2 and the base sealing block 3, and snap-fit ​​components are provided at both ends of the graphite riser body 1.

[0034] The snap-fit ​​mechanism includes multiple snap-fit ​​blocks 6, which are fixedly connected to the sides of the funnel connecting block 2 and the base sealing block 3. Two slots 9 are formed at both ends of the graphite riser body 1, and the multiple snap-fit ​​blocks 6 are slidably connected to the inner sides of these slots 9. The funnel connecting block 2 is located on the outer side of the end of the graphite riser body 1. The multiple snap-fit ​​blocks 6 on the sides of the funnel connecting block 2 and the base sealing block 3 can be slidably connected to the inner sides of the slots 9 formed at both ends of the graphite riser body 1. This snap-fit ​​mechanism ensures that the funnel connecting block 2 is securely installed on the outer side of the end of the graphite riser body 1. The installation of the funnel connecting block 2 ensures that molten metal poured into the riser body 1 must pass through the funnel connecting block 2 to enter the riser, effectively preventing molten metal from splashing outside the riser. The base sealing block 3 is installed at the bottom of the graphite riser body 1, and its sealing effect effectively prevents molten metal from flowing out from the bottom of the riser, thus preventing pollution and damage to the external environment. The graphite riser body 1 has a base sealing block 3 at its bottom. A semi-circular groove 7 is formed on the inner side of the bottom of the base sealing block 3, and a connecting block 8 is fixedly connected to the inner side of the semi-circular groove 7. The semi-circular groove 7 on the inner side of the bottom of the base sealing block 3 and the connecting block 8 fixed therein can be used to connect with the mold or other support structure to realize the positioning and fixation of the entire riser in the casting system.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The ventilation and cooling component includes two ventilation channels 5, which are respectively located inside the funnel connecting block 2 and the base sealing block 3. Multiple holes 4 are formed on the inner sides of both the funnel connecting block 2 and the base sealing block 3, and these holes 4 are connected to the two ventilation channels 5. Outside cold air can enter through the ventilation channels 5 inside the funnel connecting block 2 and the base sealing block 3. Since the ventilation channels 5 are connected to the multiple holes 4, the cold air flows out from these holes 4, exchanging heat with both ends of the graphite riser body 1, carrying away some heat, thereby reducing the temperature at both ends of the riser.

[0036] Reference Figure 4The graphite riser body 1 has a nano-ceramic coating 10 on its inner side. The nano-ceramic coating 10 has a smooth surface, making it difficult for molten metal and impurities to adhere to the inner wall of the riser. This allows for easy removal of residual molten metal and impurities after casting with simple wiping or rinsing, greatly reducing the difficulty and workload of cleaning. A steel plate layer 11 is provided inside the graphite riser body 1, positioned on the side of the nano-ceramic coating 10. The steel plate layer 11 provides additional structural strength to the graphite riser body 1, preventing deformation or cracking and ensuring the structural integrity and stability of the riser. An aluminothermic layer 12 is provided inside the graphite riser body 1, positioned on the side of the steel plate layer 11. When high-temperature molten metal is poured into the graphite riser body 1, the aluminothermic layer 12 reacts and releases a large amount of heat. This effectively reduces defects such as shrinkage cavities and porosity caused by the solidification and shrinkage of the molten metal inside the casting, improving the quality of the casting. A borax layer 13 is disposed on the inner side of the graphite riser body 1, and is disposed on the outer side of the thermite layer 12. The borax layer 13 can reduce the surface tension of the molten metal, thereby improving the fluidity of the molten metal. Borax can also help remove impurities such as oxides from the surface of the molten metal, making the molten metal purer and further improving the quality of the casting. Moreover, when cleaning the riser, borax helps the molten metal and impurities to detach from the inner wall of the riser, facilitating the cleaning process.

[0037] Working principle: First, multiple locking blocks 6 on the sides of the funnel connecting block 2 and the base sealing block 3 are slid into the corresponding slots 9 at both ends of the graphite riser body 1, completing the locking and installation of the graphite riser body 1 with the funnel connecting block 2 and the base sealing block 3. The installed funnel connecting block 2 guides the molten metal into the graphite riser body 1 when it is inverted in the riser, effectively preventing the molten metal from splashing onto the riser surface and becoming difficult to clean. The semi-circular groove 7 and connecting block 8 on the inner bottom of the base sealing block 3 can be used to connect the mold and other supporting structures, providing support and sealing to prevent molten metal leakage and environmental pollution.

[0038] The funnel connecting block 2 and the base sealing block 3 are equipped with ventilation channels 5, and multiple holes 4 on their inner sides are connected to the ventilation channels 5. During the production of electrofused bricks, cold air from the outside can enter through the ventilation channels 5 and flow out through the holes 4 to ventilate and cool both ends of the graphite riser body 1, preventing the riser from being damaged due to excessive temperature. At the same time, it helps to stabilize the temperature of the molten metal and ensure the stability of the production process.

[0039] The nano-ceramic coating 10 on the inner side of the graphite riser body 1 has excellent self-cleaning properties due to its smooth surface, effectively reducing the adhesion of molten metal and impurities, and facilitating cleaning. The steel plate layer 11 on the side of the nano-ceramic coating 10 enhances the structural strength of the graphite riser body 1, making it more resistant to the impact and thermal stress of molten metal and preventing riser deformation or cracking. The thermite layer 12 on the side of the steel plate layer 11 reacts and releases heat after the molten metal is poured into the riser, which can increase the temperature of the molten metal in the riser, ensuring sufficient feeding during the solidification process of the casting and reducing defects such as shrinkage cavities and porosity. The innermost borax layer 13 reduces the surface tension of the molten metal, improves the fluidity of the molten metal, and helps remove impurities such as oxides from the surface of the molten metal. During cleaning, borax helps the molten metal and impurities detach from the inner wall of the riser, facilitating cleaning.
