Abstract

Process for the cooking of carbon products, such as electrodes used for the manufacture of aluminum, in which the products are heated up to a temperature between 900 and 1400º c, the heating regime being such that the surface of a product does not exceed 700ºC before its core has reached 450º c, characterized in that the temperature in the core of the product is first brought to a value between 120 and 170º c, and then this temperature is brought above 450ºC in less than 10 hours (Machine-translation by Google Translate, not legally binding)
