Good price and quality Graphite Cathode block from China manufacturer A good price and quality Graphite Cathode block from China manufacturer made from high-quality anthracite, coke, graphite, etc. Good price and quality Graphite Cathode block from China manufacturer are used as cathodes for aluminum electrolytic cells.

The types of good price and quality Graphite Cathode block in China are basically divided into three categories: ordinary cathode carbon blocks, semi graphite carbon blocks, and graphite carbon blocks based on the quality requirements of the product, the selected raw materials, and the process conditions used. The common good price and quality Graphite Cathode block from China manufacturer uses anthracite calcined at 1250-1350 ℃ as the main raw material. Semi-graphite carbon blocks are divided into two types according to different production processes.

One type of good price and quality Graphite Cathode block from China manufacturer is to use high-quality high-temperature electric calcined anthracite or to use a large number of graphite fragments or even all graphite fragments as aggregates. After molding, the green product only undergoes roasting (the roasting temperature does not exceed 1200 ℃) and no longer enters the graphitization furnace for heat treatment. This type of carbon block is called semi graphite carbon block.

The other type of good price and quality Graphite Cathode block from China manufacturer uses more easily graphitized coke as the aggregate, and the raw product is roasted before entering a graphitization furnace for heat treatment at a temperature of 1800 to 2000 ℃. This type of carbon block is called semi graphitized carbon block. The former has higher strength and hardness, while the latter has better electrical conductivity and integrity. Graphite carbon block, using easily graphitized coke as raw material, should have a graphitization treatment temperature of around 2500 ℃.

The difference between semi graphite carbon blocks and graphite carbon blocks lies in the degree of ordered lattice arrangement of products, i.e., the degree of graphitization. The degree of graphitization can be expressed by the resistivity of the product. The lattice of graphite carbon blocks is basically completely in an orderly state, with a resistivity of less than 15 μ Ω? m; The degree of graphitization of semi graphite carbon blocks is low or only partially graphitized, with a resistivity of 15 to 45 μ Ω? m。 The highest heat treatment temperature for semi graphite carbon blocks is about 2000 ℃, and the graphitization temperature for graphite carbon blocks is 2500~2800 ℃. Ordinary cathode carbon block with a resistivity of 50-60m.

Graphite cathode carbon block is a conductive material used for the cathode of aluminum electrolytic cells, representing the development direction of the electrolytic aluminum industry. With the technological progress and development of the electrolytic aluminum industry, the electrolytic cell is developing towards a large capacity of over 300KVA, with higher requirements for cathode materials. The main advantages of graphite cathode carbon block are to strengthen the current, improve the current efficiency, achieve the purpose of increasing production and energy conservation, and make the electrolytic cell operate stably. The larger the cell type, the more obvious the effect of operating stability, and the more obvious the improvement of current efficiency. The unit production capacity of aluminum electrolytic cells using graphitized cathode is increased by 10-15%, and the power saving per ton of aluminum is more than 600KWH. Graphite cathode aluminum electrolyzer is one of the materials prioritized for promotion and development in the electrolytic aluminum industry by the country due to its obvious energy-saving, consumption reduction, and emission reduction effects.
