Problems solved by technology

[0002] At present, the preparation of the existing anode carbon block for aluminum electrolysis is to use the mold to change the anode carbon block into a square-shaped platform, which has the following disadvantages: the anode installed on the electrolytic cell is located at the cutting point of the electrolytic cell. Insulation material is not easy to add, resulting in serious anodic oxidation; and the weight of the residual pole is large, and the gross consumption of the anode is high

Embodiment Construction

[0015] The specific embodiments of the present invention are given below with reference to the accompanying drawings, which are used to further describe the structure of the present invention, and the specific implementation of the present invention is not limited to the following examples.

[0016] The preparation method of the special-shaped prism anode carbon block mold cover for aluminum electrolysis in this embodiment refers to Figures 4, 5, and 6, and includes the following steps:

[0017] First, measure the dimensions of the corners of the original anode carbon block quadrangular platform-shaped forming mold cover 1. According to the measured size, use 45# steel to plan out the special-shaped additional iron 2, and weld and attach it to the two small sides 3 of the mold cover. Transform the 45-degree angle on the two small sides of the mold cover 1 into a 35-degree angle by using the method, and measure and calculate the slope angle of the mold cover to be consistent wit...

Abstract

This invention relates to a method for preparing mold cover for irregular prismoid anode carbon block used in aluminum electrolysis. The method comprises: (1) measuring the sizes of the sides and corners of a mold cover for original irregular prismoid anode carbon block, processing steel blocks to obtain irregular prismoid anode carbon blocks according to the sizes, welding to combine the additional iron blocks to the two small side surfaces of the mold cover, and changing the two small side corners from 45 deg. to 35 deg.; (2) measuring the sizes of the four small corners, processing steel blocks to obtain another additional iron blocks according to the sizes, and welding to combine the additional iron blocks to the four small corners to obtain the final product. The obtained mold cover has improved performance, and can be used for lowering aluminum anode consumption.

Description

1. Technical field [0001] The invention relates to a preparation method of a special-shaped prism anode carbon block mold cover for aluminum electrolysis, and belongs to the technical field of metallurgical electrolysis. 2. Background technology [0002] At present, the preparation of the existing anode carbon block for aluminum electrolysis is to use the mold to change the anode carbon block into a square-shaped platform, which has the following disadvantages: the anode installed on the electrolytic cell is located at the cutting point of the electrolytic cell. Insulation material is not easy to add, resulting in serious anodic oxidation; and the weight of the residual pole is large, and the gross consumption of the anode is high. 3. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies in the prior art above, to provide a solution to the oxidation problem of the anode carbon block used in the electrolytic cell at the feeding...
