Siemens and Baosteel cooperate in slag
Their collaboration focuses on joint marketing and implementation of the Baosteel Slag Short Flow (BSSF) technology in steel mills worldwide, with the exception of China and Korea. The agreement Drum-granulation process is a new process for molten steel slag granulation. It is an improved version of the HK process, which was originally used for BF slag granulation [].A kind of heat resistant alloy steel was used as material of the drum, and the cooling ability for the drum was enhanced in order to fit the high temperature of Current Development of Slag Valorisation in China

Recent advances in artificial aggregate production
Granulation is a process of consolidating solid particles in the size range of 1–500 μm into aggregates with larger sizes ranging from 2 mm to 10 mm (Ennis and Litster, 1997). Presently, the commonly applied granulation methods in producing AAs can be divided into agitation granulation and compaction granulation. Hardening technologiesIn order to study the behavior of molten blast furnace slag ligament breakup into droplets by centrifugal granulation with a spinning cup, three-dimensional transient CFD model simulations were performed in the present work to study the process of the slag deformation into ligaments upon leaving the spinning cup, which eventually Minerals Free Full-Text CFD Numerical Simulation on the

Comprehensive utilisation of blast furnace slag Taylor
lator to granulate the slag, and the slag-water ratio (1:1). It is far lower than the slag-to-water ratio (5:1) of the high-pressure water granulation slag of the INBA method, and the process equipment is simple, the water consumption is small, the operating cost is low, the slag with iron content is less than 40%, and theBy 1901 the manufacture of “Eisenportlandzement” containing maximum 30% of ground granulated blast-furnace slag (ggbfs) became accepted and in 1907, the first “Hochofenzement” with up to 85% ggbfs content was produced (Moranville-Regourd 1998; Smolczyk 1978 ). Ever since, ggbfs has been successfully used in cementitious Ground Granulated Blast-Furnace Slag SpringerLink

Cooling and phase evolution of a molten blast furnace slag
Centrifugal-granulation-assisted thermal energy recovery (CAGTER) emerges as a leading technology to treat the industrial CaO-MgO-Al 2 O 3-SiO 2 melts such as blast furnace slag. However, large-scale implementation of CGATER is partly limited by the lack of a thorough understanding of the crystallization dynamics of the CMAS slag.It added that the grinding of granulated blast furnace slag was only being carried out domestically by cement companies. Imports of slag were 2Mt in 2022. This is a decline from a peak of 2.6Mt in 2018 but higher than the period 2000 2015. The price of slag, meanwhile, hit a high of US$53/t in 2022.Update on slag in the US, May 2023 Global Cement

Numerical Simulation of the Slag Granulation Process in Gas
In the heat recovery technology of molten slag granulation, gas quenching is one of the most promising and crucial technologies for high-quality resource utilization. This study performed numerical investigations on the slag granulation process through the realizable k-epsilon model and volume of fluid methodology and gained deep insight into Dry granulation is an attractive alternative to water quenching because of saving energy and reducing water consumption. In many dry granulation technologies, the high-temperature molten slag is atomized to slag particles, and the thermal energy from high-temperature slag particles is recovered by physical and chemical methods. In the Thermal energy recovery from high-temperature blast furnace slag

A new technological approach to the granulation of slag
The technological factors required to improve the operational properties of granulated metallurgical slags demanded in the building industry have been analyzed. In order to satisfy these factors, a new technology for hydro-vacuum granulation of slag melts (HVG) has been developed. It is shown that the main advantage of the proposed HVG The Centrifugal atomization process finds wide application in the production of sprays & droplets [] as well as polymer microspheres [], dry slag granulation [3, 4], metal powder production [5,6,7], etc.There is an increasing demand for powders and granules as a form of starting material for several industrial applications such as Modeling of Powder Production During Centrifugal Atomization

Forging a future in green steelmaking CSIRO
Forging a future in green steelmaking. Australian smart technology that harvests blast furnace waste and converts it into a new product to make cement, is being trialled for commercialisation in China where 60 per cent of the world’s iron waste is produced. The process, known as Dry Slag Granulation, also reduces water use and During the dry granulation for molten blast furnace slag, rotary cup is used to atomize the molten slag.In this study, the mechanism of ligament formation for molten slag granulation was investigated. The results indicated that the transition equations from direct drop formation to ligament formation and ligament formation to sheet formation, Experimental investigation on ligament formation for molten slag

Disposal of High-Temperature Slags: A Review of Integration
Coal gasification and pyrolysis. The integration of coal gasification and heat recovery from hot slags was first proposed by Liu in 2004,[10,11] which was composed of a slag granulation part using a RCA and a coal gasification part using a two-level fluidized bed.Since then, a series of experimental and theoretical analysis have been performed to Continuous improvement and decades of R&D activities created innovative solutions that aim at safety, quality, sustainability and customer benefit.

Dry slag granulation: producing valuable by-products from
Slag is a high volume by-product from the metal smelting process. Globally, hundreds of millions of tonnes of molten slags are produced each year. Close-up of molten steal showing spiral of glowing molten metal. Slag is commonly air-cooled in large pits and landfilled or used for road-based materials after crushing and screening.In addition, the rapid cooling process of slag granulation can vitrify the slag well, and the formation of the glass phase closely matches the properties required in Portland slag cement manufacturing process (Tripathy et al., 2020). Therefore, molten-slag granulation technology also has a positive significance for energy saving and emissionApplication of iron and steel slags in mitigating greenhouse
