Nalco IronGUARD™ Technology and Services
The need to make better use of the waste generated at the hot mill has led us to develop the IronGUARD programme. It employs a unique and patented new polymer that prevents the oil from adhering to the mill scale. This will keep the oil content to less than 1%. This would allow you to recycle the mill scale back to the steelmaking process via the sinter plant or blast furnace. Or you can sell the high iron-bearing material to others that can use the clean scale in their process. In either case, you eliminate the costly disposal and transportation fees.
