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.
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 ...
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 ...
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 Jahanshahi, 2008; Xie et al ...

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.
Dry slag granulation with heat recovery. Primetals Technologies, voestalpine Stahl, 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.

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.
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.
The system proved it could handle this serious over load; and other than fill ing the granulation pit to overflowing, the system work ed without any problems. In January 1999, a more serious ...
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.
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
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 ...
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.
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 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 ...
