Dry slag granulation with heat recovery. Primetals Technologies, voestalpine Stl, the FEhS – Building Materials Institute and the University of Leoben joined forces in an RD program to develop a new drygranulation technology using air to cool molten slag and recover the lost heat energy.
The invention relates to the granulation of molten slag directly from metallurgical furnaces. Known installation granulated slag containing slag chute, which consistently are hydrogenerator, a hopper sump with grate and overflow device and coupled with well installed the airlift, connected in turn with the dehydrator carousel with feeding hopper and the discharge hopper, and well air pump ...
There are various processes on the market for the granulation of blast furnace slag. The most important process is cooling in a water bath. The most common methods are the RASA system from Rasa Corporation, the INBA system (Fig. 16) from Paul Wurth, a company of the SMS group, and the IJ GRAN system from DanieliCorus.
Slag Granulation System "RASA SYSTEM" If molten slag, a byproduct produced when steel is manufactured in a blast furnace, is rapidly cooled with jet water, granulated slag is produced. Granulated slag is recycled as raw materials for cement, etc.
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 granulation unit ...

PROCESS AND INSTALLATION FOR GRANULATING SLAG. In a process for granulating slag, from a blast furnace or a smelting reduction plant, in which a granule ...
In this paper, the slag granulation and heat recovery options are reviewed and given a critical evaluation, aiming to provide a basis for future directions in slag handling. Metallurgical slags are produced at a massive rate of over 750 Mt/year, and carry a thermal energy equivalent to 40 Mt/year of coal. The potential mineral
Dry Slag Granulation – The Future Way to Granulate Blast Furnace Slag Fleischanderl, Fenzl T. 2, Neuhold R. 3 1Primetals Technologies Austria Turmstrasse 44, .
Mainly consisting of lime, silica acid, aluminum oxide, and magnesium oxide, blastfurnace slag is normally processed in granulation plants nowadays. By quenching the liquid slag, a glassy, granular product is obtained, the socalled granulated blastfurnace slag which is particularly suited for use as an extender in the production of high ...
Dry Slag Granulation. Water granulation is the most commonly used method to handle blast furnace slag and requires a granulation and a dewatering step to process the slag. In water granulation the energy in the slag is lost from water evaporation and cooling and is difficult or impossible to recover.
Dehydration facilities of the RASA (Fig. 1) is composed . ... Thus the whole system covers a large area and need long . ... Slag granulation was then observed using a Video camera. and finally ...
Dry granulation of blast furnace slag was experimented with in the Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia. In this process, molten slag is atomized under centrifugal forces on a spinning disc and the slag droplets generated are quenched and solidified quickly using air ( Xie Janshi, 2008; Xie et al ...
Jun 01, 2016· A prototype dry slag granulation system was proposed and designed in commercial scale. • The input and output flows of each slagtreatment system were identified. • Life cycle assessment on the dry slag granulation method and water quenching methods was carried out. • Economic costs and returns during the lifetime of slag were calculated.

Slag handling is an important aspect of modern blast furnace operation. Today, blast furnace slag is a saleable product (granulated slag sand used as CO 2friendly substitute of clinker in cement production) rather than a difficult and costly waste Wurth has developed the INBA ® slag granulation process, incorporating our proprietary dynamic INBA dewatering drum.
A method of controlling a supply of coolant gas to a dry slag granulation system, the system comprising: a rotary atomising granulator; a slag receptacle, for supporting a slag bed which is formed thereon when slag particles are expelled from the granulator, the slag receptacle comprising a plurality of cooling inlets for cooling respective zones of the slag bed; and at least one height ...
The orders placed in 2003 with Paul Wurth Luxembourg, Paul Wurth Metal Technology Beijing and Paul Wurth Umwelttechnik Essen comprised the engineering, supply of key components and site supervision for a central feed Bell Less Top® charging system, an INBA® slag granulation system, a gas cleaning system and a pulverized coal injection ...

RASA SYSTEM. The hot mixture of solid slag particles and water produced by contacting water with the molten slag released from a blast furnace is introduced into a tank equipped with an overow and a lter at the overow which permits a portion of the water and a minor fraction of slag nes to overow. The major fraction of larger slag particles collects at the bottom of the tank and is pumped as a ...
