No process considered the heat recovery from molten slag during granulation processes. Large scale application of stabilised steel slag powder in construction is a good way for steel slag valorisation. The practical feasibility, applicable in large scale, low cost is very important for slag valorisation processes.
TPT Dry Granulation of Blast Furnace Slag for Heat Recovery. Dry Granulation of Blast Furnace Slag for Heat Recovery Blast furnace slag is known as a by-product from the production of hot metal at integrated steel and iron mills. Approximately 300 kg of this liquid slag with a temperature of about 1500°C is tapped together with each ton hot metal.

May 05, 2013· Concept of slag granulation. The process of slag granulation involves pouring the molten slag through a high pressure water spray in a granulation head, located in close proximity to the blast furnace. Granulation process is the controlled quenching of the slag in cold water which does not give time for crystalline growth to take place.
As a valuable byproduct of the iron-making process, blast furnace slag with temperature up to 1450–1650 ° C contains a tremendous amount of sensible heat. Dry granulation and waste heat recovery via a moving bed is an attractive alternative to the conventional water quenching method due to energy-savings and the reduction in water consumption.
