In the granulation section, the liquid slag is ‘quenched’ by pouring onto it an excess water stream. The evaporated water will be condensed in a condensing tower located above the granulation tank. This proven granulation process ensures economic granulation and produces valuable and consistent properties in the blast furnace slag.

Abstract: The process of granulation in blast furnace slag (BFS) by gas q uench-ing can effectively recover the waste heat of BFS and improve the value-added nature of the BFS byproduct. With decreasing temperature, BFS crystallizes into melilite, anorthite, spinel, etc. Mineral crystallization, however, is not conducive

Effect of Water Granulation Conditions on Density and

formation is caused by a process in which steam is dissolved in the molten slag during water granulation, the steam reacts with the nitrogen in the slag, and this results in evolution of nitrogen gas and hydrogen gas. Reduction of the slag temperature is well-known as an effective technique for obtaining high density water granulated slag.5,7)

In this paper, the granulation mechanism of BFS and the amorphous phase formation mechanism of slag beads were studied by combining the physical properties of BFS and the granulation effect. The results showed that the viscosity of BFS decreased with the increase of basicity; the bigger the basicity, the higher the bead formation rate, the smaller the particle size and the more regular the slag shape.
