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
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 ...
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.

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.
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.
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 ...
The system is automated to rapidly test circuits (~1 minute tests) and store historical data. Hatch''s soft sensor uses installed flowmeters in tandem with statistical methods to calculated deviations in differential flow. Both leak detection methods result in much faster and more predictable leak detection. Dry Slag Granulation
May 17, 2019· 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.
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.
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 and thermal energy values of slags are in the order of 22 b and 3–6 b per year. Such attractive figures, together with tightening legislation on disposal of slag and the carbon footprint associated with the loss of mineral and energy ...

The slag granulation plant comprises three sections: for granulation, dewatering and storage. 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 ...
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 ...
Major slag granulation processes presently under operation are OCP granulation system, Gipromez designed plants, Rasa system and INBA slag granulations. function of slag granulation plant.

Abstract. Slag dumping and water granulation are the most commonly used slag treatment methods in the metallurgical industries. In both processes, water is present (by desire for cooling and dispersion or as a result of rain accumulation) and thus equipment and operations are designed to minimize and mitigate the risk of steam explosions resulting from the inappropriate contact of slag with water.

ROURKELA: Employees of Rourkela Steel Plant (RSP) have carried out conversion of drives of emergency water valve of the INBA Cast House Slag Granulation Plant of Blast Furnace4 (BF4) which has led to smoother functioning of the furnace. INBA cast house Slag Granulation system of BF4 is a unit which not only granulates the molten slag but also reduces the load on slag circuit.

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.
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 ...
