How are graphite plates manufactured?

Graphite plates possess excellent properties such as good conductivity, high temperature resistance, acid and alkali corrosion resistance, and ease of processing, making them widely used in metallurgical, chemical, and electrochemical industries. Graphite plates include high-purity graphite plates, graphite anode plates, and graphite bipolar plates.

So, how are graphite plates manufactured?
Graphite plates are made from high-quality petroleum coke with low ash content as the main raw material, using pitch as a binder. After molding, they undergo baking, impregnation, graphitization, and precision machining. Ultra-high conductivity graphite plates have a very high thermal conductivity and good heat transfer performance, which is more effective in strengthening furnace bottom cooling, reducing furnace bottom temperature, and slowing down furnace bottom erosion. They are suitable for the bottom and belly of blast furnaces. In terms of shape, the thermal field can be square or circular, with circular thermal fields accounting for a higher proportion in vacuum furnaces. To facilitate installation and removal from the furnace chamber, all thermal fields are constructed in a modular form.
Graphite plates usually refer to impregnated graphite carbon plates and graphite carbon bricks made from high-quality graphite carbon materials. Through impregnation with a highly acid-resistant impregnating agent, they become impermeable materials. They are refined through high-pressure molding, vacuum impregnation, and high-temperature heat treatment processes, possessing extraordinary acid and temperature resistance, making them ideal lining materials for equipment such as phosphoric acid reaction tanks and phosphoric acid storage tanks in the chemical industry.
