Prebaked anode homogenized raw material treatment method

Abstract

The invention discloses a prebaked anode homogenized raw material treatment method. The method comprises the following steps: A, grabbing and distributing petroleum coke raw materials; B, weighing the petroleum coke raw materials; C, screening the petroleum coke raw materials; D, judging the granularity: carrying out the steps E-F on the petroleum coke raw materials meeting the granularity; and carrying out the step H on the petroleum coke raw materials which do not meet the granularity; E, sulfur content detection: detecting the sulfur content of the petroleum coke raw materials in each containing cylinder, and sub-packaging the petroleum coke raw materials with different sulfur contents into different detection cylinders; F, trace element content detection: carrying out trace element content detection on the raw materials in the detection cylinders; G, removing volatile components of the petroleum coke raw materials in the detection cylinders; H, refining and crushing the petroleum coke raw materials; I, selecting optimal petroleum coke raw materials; and J, blending the raw materials. According to the invention, indexes of different petroleum coke raw materials can be classified, prebaked anodes with different quality indexes can be produced according to different indexes, and the proportioning balance of the raw materials is ensured.

Description

technical field [0001] The invention relates to the technical field of electrolysis, and more specifically relates to a method for processing prebaked anode homogenized raw materials. Background technique [0002] In the production of electrolytic aluminum, the prebaked anode as the "heart" of the aluminum electrolytic cell plays the role of introducing current into the electrolytic cell and participating in the anode reaction. Petroleum coke is the most important raw material for the production of prebaked anodes for electrolytic aluminum. 1 ton of electrolytic aluminum requires about 0.5 tons of prebaked anodes, and 1 ton of prebaked anode products requires 0.95 to 1.1 tons of petroleum coke raw materials. [0003] The quality and availability of petroleum coke are crucial to the electrolytic aluminum industry. With the rapid increase of carbon products in my country, a large amount of petroleum coke is needed as a raw material, resulting in a tight supply of high-quality ...

Problems solved by technology

[0004] At present, there are many types of petroleum coke on the market. Each petroleum coke contains different indicators. The quality of the prebaked anode products produced by different indicators of petroleum coke is different. Therefore, the quality of the prebaked anode products produced is uneven, resulting in inability to According to the need to produce the corresponding prebaked anode products
