Aug 23, 2016 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

Apr 04, 2019 Dry slag granulation process is essentially to atomize the liquid slag and then to cool the particles rapidly so as to produce a glassy slag. Atomization is done using a rotary cup air blast atomizer Fig 1. The particles cool as they travel through the air and are then cooled further in a fluidized bed. Both of these cooling processes provide ...

Recently Ecomaister Ltd in South Korea developed a Slag Atomizer Plant for the air granulation of slag which produces PS Ball Precious Slag Ball below 5 mm, the process produces large amounts of fumes from which potentially heat could be recovered, but it is not in operational practice Example Air granulation, Nippon-Kokan

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

Some Fundamental Aspects of Dry Slag Granulation

S or acid mist, which could be a significant issue around water granulation plants. The CSIROs Dry Slag Granulation DSG process is as a continuous -step prtwo ocess as shown in Figure 1. The molten slag is first atomized using a spinning disc and the fine droplets

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.

Design and Operation of Dry Slag Granulation Pilot Plant. CSIRO has been working on a dry granulation process, integrated with heat recovery, since 2002. It involves a rotary disc that atomizes ...

Products Ironmaking and steelmaking Slag Granulation

The slag granulation plant comprises three sections for granulation, dewatering and storage. 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.

Dry slag granulation is based on molten slag atomization using a variable speed rotating cup or dish see Fig. 1. The slag is fed from the slag runner via a vertical refractory lined pipe directly onto the center of the rotating cup. The rotation of the cup
