Steel slag is an inevitable derivative of steelmaking process, mainly composed of calcium, iron, silicon, magnesium and a small amount of oxides of aluminum, manganese and phosphorus. In recent years, SBM has taken various measures to make steel slag recycling equipment and achieved secondary recovery of some steel slag. With the large-scale production scale of SBM Iron and Steel, the annual production of steel slag has reached more than 1.3 million tons, but the comprehensive recovery rate of iron-containing raw materials is low, and it is necessary to follow up with supporting facilities. To this end, SBM started construction of a steel slag Vertical Roller Mill magnetic separation processing line on the basis of the original 30-ton furnace plant and supporting facilities of the steelmaking plant at the end of August last year.
The project adopts advanced, reliable and low-cost process technology. The production equipment is divided into six parts: screening, crushing, magnetic separation and vertical roller mill. Different types of magnetic separation equipment can be set according to the properties of steel slag with different particle sizes. The magnetic separation equipment has strong adaptability and high recovery rate of steel slag, and the annual processing capacity of steel slag is more than 1.4 million tons. The recovered slag powder and medium sieve block are mainly used for ironmaking sintering and steelmaking converter production, further reducing the production cost of pre-iron and steel post-process.
At present, the comprehensive utilization of steel slag at home and abroad has undergone major changes compared with the past. The guiding ideology of steel slag management has changed from a simple environmental perspective to comprehensive management and resource utilization. Steel slag can be used as iron-making flux, directly added to blast furnace or sinter, and recycled inside the steel plant. It can also be used as a cushion and structural layer of road subgrade. It is especially suitable as an aggregate paving layer for asphalt mixture. Road construction with steel slag has the advantages of high strength, good wear resistance and slip resistance, and low maintenance cost. Shanghai SBM research and development of environmentally-friendly large-scale steel slag vertical roller mill, specializing in steel slag processing, so that it can be used for sustainable use, tailor-made for the enterprise to create a good strategy.
