  • Blast Furnace Slag Granulation at the Cast House IspatGuru

    Fig 4 Schematic diagram of a slag granulation plant. Granulation section Here, the liquid BF slag is water quenched and solidified into small particles, eliminating the need for heavy crushing equipment. The liquid slag flows by runners from the BF to the granulation unit. From the runner, the liquid slag stream at around 1,500 deg C is poured into a high velocity water stream at the

  • Products › Ironmaking and steelmaking › Slag Granulation

    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.

  • Dry Granulation of Blast Furnace Slag Steel 360- Steel

    Using dry slag granulation at integrated steel plants will gain access to the sensible heat of the BF slag. The recovered energy can be used for the production of steam or electricity or for other useful preheating processes. An energy potential for recovering 20MW thermal energy or alternatively of about 6MW electric power generation from a

  • Hatch Ironmaking Technologies Dry Slag Granulation

    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.

    Jun 22, 2017· China: Hebei Zongheng Group Tangshan Fengnan Iron Steel has ordered Inba slag granulation and dewatering equipment as part of a new 12Mt/yr iron plant. Capital Engineering Research Incorporation (CERI), the general contractor, has signed two contracts with Paul Wurth for engineering and supply of four sets of Central Feed Bell

  • Slag recycling recovery

    When the liquid (molten) slag is quenched with water in a granulation plant (Fig. 5), a glassy and granular product is created, which must subsequently be ground to produce a fine powder, which is used as a clinker substitute. Ground granulated blast furnace slag (GGBFS) has similar cement-like properties to Portland cement.

  • Blast Furnace Slag Granulation / Ironmaking / Our

    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 2-friendly substitute of clinker in cement production) rather than a difficult and costly waste material.Paul Wurth has developed the INBA ® slag granulation process, incorporating our proprietary dynamic INBA dewatering drum.

  • Granulated Blast Furnace Slag an overview

    Apart from the granulated BF slag used in producing slag cement, all types of waste from any steel plant were simply dumped in the neighboring desert. Based on the production figures of the major steel plants in Egypt and the generation rates of different waste materials per each ton of steel produced, the annual waste materials generated in

  • Slag Granulation with Continuous Dewatering Ironmaking

    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

  • Granulated Blast Furnace Slag an overview

    Magnetic reseparation of the steel slag can improve the efficiency of intergrinding steel slag and the OPC clinker by about 50% compared with intergrinding OPC clinker and nonmagnetically reseparated steel slag. The grindability of mixtures of steel slag and OPC clinker depends on the relative content and initial pregrind size of the steel slag

  • Dry Slag Granulation: A Path to Improving the Safety and

    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.

  • Design and Operation of Dry Slag Granulation Pilot Plant
