Iron and steel enterprises can take advantage of the existing regional location of steel mills, and the source of raw materials is fully guaranteed; The steel mill has advanced and strict scientific management experience, and has experienced technical team and staff team, which provides the guarantee of organization, technology and production management for the implementation of the project and market development; Steel plant power supply, water supply source reliable, convenient transportation, good cooperation conditions, construction conditions are very superior. To sum up, the construction of steel slag micro-powder projects in iron and steel enterprises can not only turn waste into treasure, improve the added value of steel making, create considerable economic benefits for iron and steel enterprises, but also protect the environment, in line with the policy direction of steel and cement industry structural adjustment. The development of steel enterprises layout steel slag powder project is a good thing to benefit the country and the people, has a broad future and is of great significance, and will play a positive role in promoting the construction of "waste free city" and promoting the sustainable development of the steel industry.
