Prebaked anode is an important product in the field of chemical production raw materials, mainly used in aluminum electrolysis industry. Its upstream and downstream related products mainly include petroleum coke, coal tar pitch, alumina and so on.

1. Upstream related products

(1) Petroleum coke: Petroleum coke is one of the main raw materials for pre-baked anodes, accounting for a large proportion of its cost. The quality of petroleum coke has an important influence on the performance of prebaked anodes, so the selection of high-quality petroleum coke is the key to the production of high quality prebaked anodes.

(2) Coal tar pitch: Coal tar pitch is the binder of prebaked anode, which has an important influence on the thermal shock resistance, oxidation resistance and electrical conductivity of anode. Different types of coal tar pitch have different effects on the performance of prebaked anodes, so it is necessary to select the appropriate coal tar pitch according to the production requirements.

2. Downstream related products

(1) Alumina: Prebaked anodes are mainly used in the aluminum electrolysis industry, and alumina is the main raw material for aluminum electrolysis. Therefore, the downstream associated products of the prebaked anode mainly include alumina. The quality and purity of alumina have an important influence on the efficiency and product quality of aluminum electrolysis, so it is necessary to use high quality pre-baked anodes to ensure the normal progress of aluminum electrolysis.

(2) Aluminum ingot: The product of aluminum electrolysis is aluminum liquid, which becomes aluminum ingot after cooling and solidification. Accordingly, downstream associated products of prebaked anodes also include aluminum ingots. The quality and purity of aluminum ingots are affected by the performance of pre-baked anodes, so it is necessary to use pre-baked anodes with stable performance to ensure the quality and purity of aluminum ingots.

In short, the upstream and downstream related products of pre-baked anodes involve many fields, such as petroleum, coal, alumina, aluminum electrolysis, etc. Understanding the properties and characteristics of these related products will help to better understand and apply prebaked anodes to improve the efficiency of chemical production and product quality.
