Building Materials - Solid Waste Recycling (Rock wool/Mineral wool Furnace):
Steel slag is the waste slag produced in the steel making process of iron and steel enterprises, steel slag generally contains 7% to 10% scrap steel, after magnetic separation processing, about 90% of the scrap steel can be recovered. In addition to some scrap steel, the main mineral composition of steel slag is dicalcium silicate, calcium ferrite and RO equal, similar to the chemical composition of cement clinker, can be used as building materials. In addition to the main steel slag produced by converter steelmaking, there are also steel slag types such as hot metal desulphurization slag and refined steel slag, which can become valuable resources if fully utilized.
Examples:
In the field of building materials - steel slag, is the waste slag material generated in the process of steel making in iron and steel enterprises.
The basic principle and route of the material:
Key technology:
1. Optimized magnetic separation process of steel slag.
2. New high-efficiency broadband magnetic separator.
3. Separate classification and magnetic separation of hot metal desulphurization slag, 100% recovery of powdery materials.
4.Waste heat energy recovery technology of hot metal desulphurization slag, using waste heat for heating,
5, LF furnace refining slag pressing technology
6. Development and utilization technology of powdery iron-containing materials in metallurgical slag
