Magnesia and carbon-based refractories are the predominant lining materials for modern steelmaking equipment. In a new process developed by Rutgers Chemicals AG, a hot melt coal-tar resin powder with a softening point well above 200 deg C, is produced from a conventional coal-tar pitch. Moreover, the harmful benzoapyrene is largely removed in this process so that Carbores only contains 3% of the original amount of benzoapyrene.
