Description

Technical Field

[0001] This utility model relates to the technical field of cathode steel rod casting equipment, and specifically discloses a copper-embedded cathode steel rod casting equipment for aluminum electrolysis. Background Technology

[0002] Cathode steel rods play a crucial role in electrolytic production. Their quality and design directly affect the stability, efficiency, and cost of electrolytic production. Therefore, reducing voltage drop is an important way to reduce DC power consumption in aluminum molten metal. In the process of increasing the size of aluminum electrolytic cells, the electrode rod consists of two parts: the cathode rod that connects to the workpiece and the clamp that is fixed to the edge of the plating tank. The cathode rod is generally composed of a copper core and a steel rod. In order to ensure close contact between the copper core and the steel rod, a casting machine is often used to cast the copper core into the steel rod by high-temperature melting.

[0003] Chinese Patent No. CN222370306U discloses a casting machine for copper-embedded cathode steel rods used in aluminum electrolysis. The machine includes a frame and a casting box, with the casting box fixed to the upper part of the frame. A water bath cooling tank with an upward-facing opening is fixed to the bottom of the frame. A hollow cover is fixed inside the water bath cooling tank, and several mesh positioning sleeves are fixed to the upper part of the hollow cover. Elastic positioning components are provided around the inner walls of each mesh positioning sleeve. A top plate is provided at the lower end of each mesh positioning sleeve, and a lifting drive component is provided inside each hollow cover. A diversion pipe is provided below the casting box, and several casting pipes are connected to the lower end of the diversion pipe. This invention facilitates the simultaneous casting of copper cores into multiple steel rods, effectively ensuring casting efficiency. The water bath cooling method allows for rapid cooling and molding of the molten copper inside the steel rods, thus quickly casting cathode steel rods composed of copper cores and steel rods, effectively improving the efficiency of cathode steel rod casting.

[0004] In the process of using the above-mentioned device, after the casting of a set of steel bars is completed, the bars are removed and another set of steel bars to be cast is installed and then the casting is carried out again. This process is inefficient. In addition, the above-mentioned device uses spring clamps to fix the steel bars, which does not provide high clamping stability. Therefore, a copper-embedded cathode steel bar casting device for aluminum electrolysis is needed to solve the above problems. Utility Model Content
