Preface for Thematic Section: Slag Granulation SpringerLink

May 31, 2019As a “wet” process, water granulation cannot recover high-grade waste heat from molten slags. The process consumes a large amount of water (about 1 ton of water per ton of slag is lost through evaporation) and may emit acid mist, H 2 S, and SO 2, causing serious air pollution. Furthermore, the wet granulated slag has to be dewatered at a

Hatch Ironmaking Technologies Dry Slag Granulation

Dry Slag Granulation. Water granulation is the most commonly used method to handle blast furnace slag and requires a granulation and a dewatering step to process the slag. In water granulation, the energy in the slag is lost from water evaporation and cooling and is difficult or impossible to recover.

Slag granulation using water sprays is now an established technology that not only simplifies blast furnace casting floor operations but also provides an economical route for producing of a valuable raw material for a host of industries. The slag granulation plant comprises three sections: for granulation, dewatering and storage.

Granulated Blast Furnace Slag an overview

Although the history of the use of blast furnace slag can be dated back to as early as 350 BC, it had been basically used as an aggregate material, until the hydraulicity of granulated blast furnace slag was found. Now, granulation is currently one of the dominant treatments of slag, including nonferrous slags, copper, and zinc, for instance.

Dry Slag Granulation: A Path to Improving the Safety and

Abstract. Slag dumping and water granulation are the most commonly used slag treatment methods in the metallurgical industries. In both processes, water is present (by desire for cooling and dispersion or as a result of rain accumulation) and thus equipment and operations are designed to minimize and mitigate the risk of steam explosions resulting from the inappropriate contact of slag with water.
