May 09, 2019· Primetals Technologies has developed a new innovative blast furnace dry slag granulation process with heat recovery at the voestalpine pilot plant in Linz, Austria. You want to know more about our ...

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.

Using dry slag granulation at integrated steel and iron mills enables the usage of the sensible heat of the blast furnace slag. Therefore, a new plant has been installed by Siemens VAI in cooperation with Montanuniversitaet Leoben at the Chair of Thermal Processing …

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.

Granulation is the process of forming grains or granules from a powdery or solid substance, producing a granular is applied in several technological processes in the chemical and pharmaceutical industries. Typically, granulation involves agglomeration of fine particles into larger granules, typically of size range between and mm depending on their subsequent use.

Jul 31, 2002· (3) Sulfide is emitted from the slag into an air by the water quenching. (4) A post process for drying slag is a must after the water quenching. (5) The thermal energy of high temperature slag is wasted without recovery. To solve these problems, we studied the dry granulation of the molten slag by rotary cup atomizer (RCA).

Dry granulation of titania slag was carried out at the 500 kW DC furnace on site. In this instance compressed air was used as granulation medium. Two rectangular guide plates placed on the slag taphole side of the furnace channelled granulated particles produced during the granulation trials.

THE DRY BLAST FURNACE SLAG GRANULATION AS RESOURCE AND ENERGY ECONOMY IN THE METALLURGY Elena Konchenko Donetsk National Technical University, Ukraine Slag treatment is the main ecological problem of the modern Ukraine metallurgy manufacture. The blastfurnace slag is the byproduct of the ironmaking process.

Dry Granulation Concept. Dry slag granulation is based on molten slag atomisation using a variable speed rotating cup or dish (see Figure 1). The slag is delivered on to the centre of the cup from a slag runner via a vertical refractory lined pipe. The rotation of the cup forces the slag outwards to the cup lip where it is atomised (see Figure 2).

Dry granulation of liquid BF slag is being developed in many countries along with heat recovery process. The dry granulation process of liquid slagis described below. Dry slag granulation process is essentially to atomize the liquid slag and then to cool the particles rapidly so as to produce a glassy slag.

At the present molten slag from a blast furnace () is granulated by impinging much water without any recovery of its much sensible heat (1823K), polluting water and atmosphere. To solve these problems, we studied the dry granulation of molten slag by Rotary Cup Atomizer (RCA), in …

Heat recovery during slag granulation provides energy recovery of 20 MWth or 6 MWel regarded to a slag mass flow of 1 t/min. springer. Siemens VAI wants to build a pilot plant for dry slag granulation for testing the possibility of integrated heat recovery, needing small amounts of liquid slag …

Although Pickering's plant design for combined dry granulation and heat recovery was only a proposal, Davy McKee, and then VAIUK [37][38] [39], continued development [7] of spinning cup dry ...

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 ...

Siemens VAI wants to build a pilot plant for dry slag granulation for testing the possibility of integrated heat recovery, needing small amounts of liquid slag for the test performance. This is where the FlashReactor enters the project as upstream melting unit.
