Production Practice

To comprehensive utilize the large amount of solid wastes from the production process, Iron making plant gradually increases solid wastes proportion in blended material for sinter by a series of process improvement and equipment upgrading. These approaches optimize technology index of blended material and provide refined material for blast furnace. Thus it creates considerable economic and social benefits the environmental via economizing the resources and reducing the environmental burden.

Furnace Slag

With the gradual depletion of high-quality iron-ore resources, ironmaking blast furnaces have gradually shifted to using high-content Al2O3 iron ore. Under this condition, the addition of MgO in the slag is adopted to alleviate operation problems caused by the high content of Al2O3. However, the proper value of the MgO/Al2O3 ratio for blast-furnace slag systems (Al2O3 = 8–25%) is not systematically studied. In this paper, we discuss the proper MgO/Al2O3 ratio on the basis of blast-furnace slag systems under different Al2O3 contents. On the basis of thermodynamics and phase-diagram analysis, it could be concluded that: (1) the MgO/Al2O3 ratio is not limited when Al2O3 in slag is less than 14%, (2) the MgO/Al2O3 ratio is required to be in the range of 0.40–0.50 when Al2O3 in the slag is 15–17%, and (3) the MgO/Al2O3 ratio should be 0.45–0.55 when Al2O3 in the slag is larger than 18%. The proper MgO/Al2O3 ratio value has been established in various industries, and it has achieved significant economic and social benefits.

Furnace Slag

Sialite, made according to the theory of simulation to formation of rock, is a new aluminosilicate-based cementitious material. Production of sialite does not require calcination, which consists of a main body (90%-97%) and an auxiliary body. Main body is made up of solid wastes such as fly ash, gangue, blast furnace slag, steel slag, red mud, waste bricks, waste glass and any other types of slag produced as a by-product in burning processes. The auxiliary body is a diagentic substance made by natural minerals. Sialite products have been successfully put into practice, which have the characteristics of cleaning production and low consumption of natural resources. Therefore sialite technology would provide an efficient method for promoting the development of a sustainable economy.
