Dry Slag Granulation Steelmaking slags are typically dumped to ground and used as low-value road aggregate. Hatch's dry slag granulation process uses air to directly granulate slag. The dry slag granulation advantages include improved safety, reduced noise and pollution and ability to access higher value-added slag markets.

Granulation of molten slag for heat recovery. Abstract: A large amount of various molten oxides, such as steelmaking slag and lava, is cooled without heat recovery. For example, the amount of slag as a byproduct of steelmaking, over 1723 K in temperature, reaches 30 million tones annually. Although the systems for efficient heat recovery from ...

Basic oxygen steelmaking (BOS) slag, a product of hot metal element (e.g., Si, Mn, Fe, P) oxidation and flux (e.g. lime, dolomite) dissolution, plays a critical role in the production of high-quality crude steel, although its behavior inside the BOS vessel (formation and reaction with metal droplets and gas) is still not clear and its recycling has always been challenging.

Although granulation does enhance the hydration characteristics of BOF slag, its hydraulic reactivity is far inferior to granulated blast furnace slag (GBFS) due to the presence of inert materials. As it does not affect the steelmaking process, granulation is the only slag engineering process that steel makers may adopt.

Granulated BOF slag by Wheel-granulation process (HK) HK process was first applied in Benxi Steel in 2004 for 3×120t and 3×150t BOF. ... Table : Standards for ironmaking and steelmaking slag valorisation. Current State of Ironmaking and Steelmaking Slags Valorisation in China

IRONMAKING AND STEELMAKING Slag Granulation Systems Efficient blast furnace slag granulation contributes to low-cost hot metal and turns a residue into a resource 10/115 A modern blast furnace can produce more than a million …

The process of slag granulation involves pouring the liquid slag through a high pressure water spray in a granulation head, located in close proximity to the BF. Granulation process is the controlled quenching of the slag in cold water which does not give time for crystalline growth to take place.

The process of the molten slag heat recovery consists of two parts, namely dry granulation and heat extraction (Figure 1). Two types of dry granulation techniques are …

Dry slag granulation is the key to molten slag heat recovery. In this paper, we will present our current status on BOF slag modification and dry granulation. Therefore, the paper will be …

of steelmaking slag (aggregate) and ground granulated blast-furnace slag (binder)2,3). Ferroform can be used as a substitute for concrete blocks and natural stones. To date, Ferroform has been used by JFE Steel as cover blocks and artificial stones instead of ripraps in vari-ous port repair works. In addition, a technical manual4)

However, a dry slag granulation system had not yet been deployed in the non-ferrous industry. Although it has demonstrated success in the steelmaking industry for decades, adoption of a dry granulation solution in non-ferrous industries has been challenged by the technical risks associated with process uncertainties and by the financial risks associated with …

Converter slag, also known as Basic Oxygen Furnace slag, is a by-product of steelmaking that is produced in large quantities worldwide. It currently has few applications, because the presence of free lime often prevents the use as aggregate, while the low reactivity makes it undesirable as a cement replacement.
