Description

The development and evolution of carbon additive
In the initial stage of the steelmaking industry, the carbon addition material used was the waste from graphite electrodes, graphite blocks and other carbon products, which had more impurities, poor sources, expensive prices, and the produced steel had poor quality. Later, calcined petroleum coke was used as a carbon additive, which could ensure the output and the cost was relatively low, and it was widely adopted by some domestic steelmaking manufacturers. However, the products produced with this kind of carbon additive were still relatively ordinary civil steel.

With the development of science and technology, the quality requirements for steel in high-end fields such as high-grade cars, warships, aerospace and other high-precision and advanced fields are also getting higher and higher. In the early 1990s, a carbon enterprise in Xinzheng, Henan Province developed a new production method of carbon additive. That is, petroleum coke was loaded into a graphitization furnace. Under a high-temperature environment, the arrangement of carbon atoms presents a microscopic graphite morphology, and at the same time, the content of impurities in the carbon additive can be reduced, the carbon content of the carbon additive can be increased, and the content of sulfur, volatile matter, ash and other substances can be reduced. After practical application by many domestic and foreign steel enterprises, the steel produced with this kind of carbon additive as an additive can greatly improve the quality and performance of the steel and can meet the demand of special industries for high-quality steel and special steel. This is also the high-quality carbon additive recognized in the domestic and international markets.
