A review on graphite surface modification methods towards low carbon-containing refractories
摘要
The rapid development of iron and steel metallurgy technology has promoted the continuous innovation and iteration of carbon-containing refractories for clean steel smelting. To meet the high-quality requirements for clean steel production and full exploit the performance advantages of carbon-containing refractories in dynamic smelting environment, it is necessary to explore the role of graphite and modified graphite in carbon-containing refractories. Based on this, graphite surface modification methods, including surfactants, surface oxidation, and surface coating, and their applications in carbon-containing refractories are reviewed. The advantages and disadvantages of each method are analyzed for practical use. Furthermore, combined with the existing problems, the application prospect of improved graphite in carbon-containing refractories is discussed.
