Description

Application
Carbon Additive Graphitizing carburizer: petroleum coke is a by-product of refining crude oil. Residuum and petroleum asphalt obtained by constant pressure distillation or vacuum distillation of crude oil can be used as raw materials for manufacturing petroleum coke, and then raw petroleum coke can be obtained after coking. The production of raw petroleum coke is less than 5% of the crude oil used. Raw petroleum coke has a high content of impurities, so it can not be used as a carburizer directly, but must be calcined first. Petroleum coke is calcined to remove sulfur, moisture and volatile matter. Calcining crude petroleum coke at 1200-1350 ºC can make it a basically pure carbon. However, the content of sulfur and nitrogen can not meet the production requirements of high quality cast iron products. Therefore, it is necessary to obtain lower sulfur and nitrogen content under higher temperature. It also makes the arrangement of carbon atoms show the micro morphology of graphite. More conducive to the improvement of cast iron quality. And this high temperature treatment process is called graphitization.
