  Experimental study of rotating dry slag granulation unit: …

  2016825 · This paper focuses on an experimental study of dry slag granulation process using an analogue for BF slag (a mixture of rosin and paraffin wax). This analogue can be used to experimentally study dry slag granulation at a relatively low temperature of 130 °C compared to BF slag at 1500 °C. Different ranges of operating conditions in terms …

  Heat Exchange in the Granulation Chamber of an Installation for Slag ...

  2019122 · Their yield is equal to 0.3–0.6 tons per 1 ton of cast iron. Liquid slags are released from the blast furnace at a temperature of 1400–1500 °C and contains significant amounts of sensible heat: 1600–1800 MJ in 1 ton of slag, which is equivalent to 55–61 kg of standard fuel [ 1, 2 ]. At present, a part of liquid blast-furnace slag is ...

  CFD modelling of dry slag granulation using a novel …

  2016125 · CSIRO is developing a novel DSG process based on a spinning disc technology [1-4]. This process utilises centrifugal force to break up a molten slag stream into droplets, which are quenched by cold air and solidified into glassy granules for cement manufacture. The process is also able to recover the sensible slag heat as hot air.

  A new technological approach to the granulation of slag …

  2021113 · 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 …

  201133 · granulation process must be assessed. The likelihood of SREs, (Sudden Release of Energy) must be understood and appreciated, as such a SRE can have devastating effects in a poorly designed granulation plant. This phenomenon refers to a sudden explosion-like expansion that can sometimes occur spontaneously between hot …

  INBA slag granulation system: Environmental process control

  TL;DR: In this paper, a new technology for hydro-vacuum granulation of slag melts (HVG) has been developed, where the main advantage of the proposed HVG process is the provision of forced high-speed vortex convection of water, with the effect of vertical suction, crushing, and degassing of the three-phase (water-slag granules-water vapor) …
