[0021] The cross section of the second angle iron guard is in the shape of a 90-degree arc, which can increase the structural strength of the edges and corners of the prefabricated body and reduce the destructive force on the anode carbon block when the edges and corners of the prefabricated body collide with the anode carbon block;
