Example Embodiment

[0022] figure 1 , figure 2 The prebaked anodes shown are prior art products.

[0023] like image 3 The vibration machine forming mold shown is except that the structure of the forming mold box is improved, and it is a known technical equipment, including Figure 4 Double-sided hydraulic die clamp shown.

[0024] The forming mold box 6 is provided with bayonet sockets 10 on the inner walls of opposite sides respectively, wherein the bayonet sockets on one side pass through the side walls, such as image 3 shown on the right. One end of the slotted template 8 is higher than the other end (30mm), and the high end corresponds to the right side of the forming mold box.

[0025] The following is the specific operation process:

[0026] (1) The forming mold box 6 of the vibration machine is lifted, leaves the vibration table 9 of the vibration machine, and hovers above the vibration table of the vibration machine;

[0027] (2) On the vibrating table 9 of the vibration machin...

Abstract

The present invention is process of producing prebaked anode block with grooves in bottom or side through die pressing under vibrating condition. The production process includes mainly a vertical paste distributing step capable of maintaining the flowability of the paste and a secondary cooling step to meet the requirement of demolding on the paste curing state. The production process has easy demolding, low power consumption and high production efficiency.

Description

technical field [0001] The invention relates to a carbon material anode groove forming process, in particular to a mold method groove forming process at the bottom or side of a prebaked anode carbon block for aluminum electrolysis. Background technique [0002] The electrolytic aluminum industry both at home and abroad needs to use prebaked anode carbon block as the anode of the electrolytic cell. At present, the bottom of the anode carbon block widely used is flat, so there is a slow heating rate and a large gas film resistance at the bottom of the anode, which increases power consumption. After using the anode carbon block with grooves on the bottom or side, a prebaked anode carbon block with fast heating speed and small gas film resistance at the bottom of the anode can be obtained, thereby reducing power consumption and carbon block consumption. [0003] For anode carbon blocks with grooves on the bottom or sides, the grooves are generally 1 to 3 channels vertically or ...
