Casting technology of EPC for anode steel claw

The anode steel claw for electrolytic aluminum is also called electrolytic claw. There are parallel three claws, four claws, three-dimensional four claws, six claws, eight claws, double anode steel claws and other models. The anode steel claw on the site of hollingoler is four claws. The anode steel claw is an important conductive part of the aluminum spot solution industry. The anode steel claw, together with the aluminum guide rod and the anode carbon block, forms the anode guide rod group, which is used as the anode of the electrolytic cell to electrolyze aluminum.

According to the size of the sand box and the part size of the anode steel claw, the casting plan of one box and two pieces is selected. There are four claws of the anode steel claw upward and each claw has a riser for feeding. Combined with production, the advantages of this kind of casting plan are obvious feeding effect, and the steel claw is not easy to have casting defects such as shrinkage cavity and shrinkage porosity. However, the disadvantages of this kind of casting method are obvious. 1. It takes a lot of time and effort to bury the steel claw. After the steel claw is buried, it needs to scrape off the coating at the bottom of the claw and brush hot glue, and then place the riser. If the riser is placed in a deviated position, it is easy to cause deformation of the four claws, not in the same place In a straight line, it will cause waste products; 2. The post-processing is more complex, so it will take time and effort to cut off the risers and then put them on the milling machine; 3. The most important thing is that the production rate of this casting scheme is low, resulting in high casting cost, reducing the profits of the enterprise; 4. Considering the size of the sand box, the height of the sand box is not suitable for bottom pouring, the thickness of the bottom sand and the top sand is not enough, one is easy to damage the sand box, the other is easy to cause collapse Box out the waste. Therefore, the top pouring scheme is adopted.
