May 05, 2013· Concept of slag granulation. 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 take place.
Primetals Technologies has provided blast furnace engineering, project excellence and expertise to customers world-wide for over a century. Our technology base covers the entire blast furnace process route from hot blast and raw material handling, through the furnace and casthouse, to gas cleaning and hot metal / slag processing.
PDF | Molten slags of blast furnace is a second resources with great value of 1600~1 800 MJ sensible heat per ton. At present, water-quenching process plays a leading role in recovering waste heat ...
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 properties in the blast furnace slag.
Dry slag granulation is destined to replace conventional water granulation of molten slags in the not too distant future, creating a paradigm shift in the history of slag treatment. In this dry process, molten slag is atomised under centrifugal forces on a spinning disc and the slag droplets generated are quenched and solidified quickly using air.

The slag granulation process and free-surface film flow on the rotary disk (a) a typical static image from high speed video recording of the slag granulation by a rotary disk in CSIRO's dry slag granulation process, (b) schematic of the film thickness profile of molten slag on the rotary disk.
Zhou et al. [12] in the literature is however not available. The range of operating carried out an experimental analysis of the dry slag granulation conditions under which particle formation is ensured is also not process using blast furnace slag and reported the effect of slag known.
The wet granulation process operates with a high water to slag ratio of about 8:1. The advantage of the wet process is that it is accepting wide fluctuations in the mass flow and physical/chemical properties of the slag. However, the wet process faces also significant disadvantages:
that no slag, matte, or alloy responds in similar fashion to a granulation practice. This paper addresses three issues, namely: • Water-granulation of BOF steel slag, without processing it to render it environmentally safe, physically and chemically acceptable for use by the construction industry, and the process economical
granulation treatment, which can simplify the handling of the slag out of the EAF and keep under control the structural constitution of the slag thus making possible a recycling of EAF slag after only one treatment process, completely eliminating the risk of swelling and elements leaching to the environment.
The combined avoided GHG emissions for dry granulation over wet granulation were 87 kg CO 2 e/t slag, and 867 kg CO 2 e/t slag compared to air cooling of slag. Calculation of these process credits ...
Wet granulation of titania slag Description and operation of the wet granulation plant Wet granulation of titania slag was carried out at the research and development facilities of Exxaro in Pretoria. Ilmenite was smelted in the 1.5 MW DC furnace at this facility. The typical titania slag tap mass was approximately one ton.
To obtain a good slag reactivity or hydraulicity, the slag melt needs to be rapidly cooled or quenched below 800 °C in order to prevent the crystallization of merwinite and melilite. To cool and fragment the slag a granulation process can be applied in which molten slag is subjected to jet streams of water or air under pressure.
to easily penetrate the slag layer during addition as well as allow for a rapid melting and dissolution in the hot metal bath. The granulated product has a homogeneous composition identical to the metal fed into the granulator and without the variations in composition that is obtained when casting in sandpits. 4 GRANSHOT metal granulation process
In the Baosteel Slag Short Flow (BSSF) granulation process developed by Baosteel, the liquid slag is transferred to a granulation drum where it is treated with injected water with a dwell time between three and five minutes, which significantly reduces the amount of unreacted free lime.
Granulation is the process of collecting particles together by creating bonds between them. Bonds are formed by compression or by using a binding agent. If one were to make tablets from granulated sugar versus powdered sugar, for example, powdered sugar would be
them, slag granulation process by a centrifugal force, which is also called DCG process, has proved its advantages due to its simpleness, controllability, less energy consumption and more sensible heat recovery in the past years.5–9) In this Modeling on Dry Centrifugal Granulation Process of Molten Blast Furnace Slag
