Hatch Steelmaking Technologies | Dry Slag

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. Custom Robotics Solutions. Steelmakers are adopting newer, safer

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. This proven granulation process ensures economic granulation and produces valuable and consistent

CFD modelling of dry slag granulation using a novel

CSIRO's dry slag granulation process. The 2D CFD model can be used to give timely predictions that allow one to explore and select appropriate design and operating conditions for producing a slag film that will ultimately break up into droplets of desired size; and the 3D CFD model can then be applied to predict the size distribution of these droplets. The relatively efficient nature of the

Preface for Thematic Section: Slag Granulation |

31.05.2019· Water granulation of slag has some shortcomings when measured against increasingly stringent requirements for sustainable operations. As 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

Prediction on particle size characteristics of high

01.10.2020· The slag flow rate, which reflects the processing capacity of the DSG (dry slag granulation) device, and the rotational velocity, which is easily adjusted during actual production, are both critical influencing factors. In this study, the slag flow rate was set to 1.5–2.5 kg/min, and the disk rotating speed was 1200–2400 rpm. As clearly evidenced in

chile granulating slag dryer

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.

Some fundamental aspects of the dry slag

Dry slag granulation (DSG) has the potential to make a fundamental change in slag treatment and deliver a more sustainable alternative compared with the conventional water granulation process

Some Fundamental Aspects of Dry Slag Granulation Process

granulation process and the dynamics of slag droplet collision with solid surfaces will be covered. Published studies on the thermodynamics of sulphur in slags and kinetics of sulphur transfer between blast the furnace slags and oxidising gas mixtures have been reviewed to ascertain the effects of oxygen ial pressure on part sulphur solubility in slags as well as the rate of desulphurisation

Process for granulation of slag - Paul Wurth S.A.

22.02.1983· Process for granulation of slag . United States Patent 4374645 . Abstract: The granulation of molten material, blast furnace slag for example, is accomplished by wetting the slag with a stream of water and thereafter transporting the thus formed granules away from the point of granulation with the water stream. Water consumption is minimized and average grain size increased

Siemens and Baosteel lend a hand for slag

In Baosteel's BSSF granulation process, the liquid slag is moved to granulation drum for treatment with injected water having dwell time between 3-5 minutes that reduces the unreacted free lime amount. To avoid emissions of dust & hazardous substances, the hermetically sealed vessel and central vapor extraction system are used. This process

Dry Granulation of Blast Furnace Slag - Steel360

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 the rapid cooling necessary for the formation of
