内容简介

About 70 % of all refractory products are used in the steel industry. When they are spent, they can be a valuable source of raw materials. Therefore it is necessary, to sort the waste and recycle it. The authors want to show, how this is done by Horn & Co. Group. The different areas of a steel mill are considered, what materials are used, how they are processed and which secondary raw materials are produced from. Using the example of some of their derivative products, the suitability of these regenerates is shown and their cost advantages will be outlined.
