Slag granulation using water sprays is now an established technology that not only simplifies blast furnace casting floor operations but also provides an economical route for producing of a valuable raw material for a host of industries. The slag granulation plant comprises three sections: for granulation, dewatering and storage.
15/2/2020#0183;#32;Water quenched slag is a byproduct in an ironmaking plant. Ground granulated blast furnace slag can be widely used in the cement and concrete industry because of its latent hydraulic property. At present, using ground blast furnace slag as a substitute for Portland cement can reduce the CO 2 emissions in the cement manufacturing process by 20%~40% [,, ]. However, with the water

Slag Granulation with Continuous Dewatering and Pollution Control. Slag Granulation with the INBA Dewatering System Molten slag is often considered as a waste material when it is cast into slag pits. INBA slag granulation and dewatering system is the proven route for converting molten slag into a value added product for the cement industry. The INBA system comprises two main components the
The plant for granulation of blast furnace slag is an addition made within the scope of the modernization project for the existing Blast Furnace, and is also part of the technological entity for production of crude iron. The technology of slag processing through granulation starts by effusion of slag from the Blast Furnace. The melted (liquid) slag at the temperature of 1300#176;C 1550#176;C is
Slag Supply The slag is fed to the granulator via a slag runner which is directly connected to the blast furnace tap hole. Based on the fact that the blast furnace slag tapping flow will exceed the granulator capacity, the slag flow is limited to a specific flow level applying refractory slag divider.
The main objective of the slag granulation plant is the processing of liquid BF slag into valuable raw materials for the cement and construction industries. The parameters affecting the quality of the granulated slag include (i) chemistry of the liquid slag, (ii) temperature of the liquid slag, (iii) glass content of the granulated slag, and (iv) average distribution of the granulated slag particles.
The slag granulation area links the hot slag runner of the blast furnace and the INBA dewatering system. This link is directly accomplished through the use of a granulation tank. The granulation tank creates a compact layout, which allows a reduced water circuit design with op timal heat transfer conditions in addition to better product quality.
Blast furnace slag is known as a byproduct from the production of hot metal at integrated steel and iron mills. Approximately 300 kg of this liquid slag with a temperature of about 1500#176;C is tapped together with each ton hot metal. This results in a worldwide annual production of

Paul Wurth has developed the INBA #174; slag granulation process, incorporating our proprietary dynamic INBA dewatering drum. With about 300 references, it is the most popular and effective means of processing blast furnace slag in the world today. The process is highly flexible; and the compact subplant can be applied to any furnace configuration.
17/5/2019#0183;#32;Slag granulation system produces granulated slag, which is mainly used as a raw material for cement and concrete aggregate, by quenching molten blast furnace slag with water. Paul Wurth Group (hereinafter PW) has more than 260 references worldwide for the supply of slag granulation systems and INBA dewatering drums. Based on PWs
Keywords: Blast Furnace, Dry Slag Granulation, Slag Sand, Heat Recovery, Cement, Carbon Footprint, CO 2 reduction, Energy Efficiency INTRODUCTION Each year, approx. 400 million tons of blast furnace slag is produced worldwide with a tapping temperature of around 1,500#176;C. Currently, the slag is granulated in wet granulation plants using large
development of this plant is now underway and is scheduled for installation at the site of an industrial partner in early 2016 where full slag flow will be fed directly to the plant from Blast Furnace slag runners. This paper will show the development path taken to date and the planned route to our goal in 2016 of being the first to industrialise the game changing process of dry Slag
