Dry granulation of blast furnace slag for energy recovery around 300 kg of liquid slag is produced as byproduct while producing one ton of hot metal in a blast furnace bf. this slag is at a temperature of around 1500 deg c and has a sensible heat of approximately 400 m cal per ton.
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 technology for research and development. in this project there are the co ...
Although the history of the use of blast furnace slag can be dated back to as early as 350 bc, it had been basically used as an aggregate material, until the hydraulicity of granulated blast furnace slag was found. now, granulation is currently one of the dominant treatments of slag, including nonferrous slags, copper, and zinc, for instance.
Summary due to the necessity to reduce co 2 emissions in cement making the partial substitution of cement clinker by granulated blast furnace slag gbfs has become established. this article deals comprehensively with the granulation process of gbfs as well as with the effects of the granulating process on the properties of gbfs.
Investigations have been carried out into the development of bricks from granulated blast furnace slag, a byproduct of the iron and steel industry. the study reveals that good quality bricks can be produced from a slag-lime mixture and sand by pressing the mix at a pressure of 50 kgcm 2 .
The slag condensation and granulation plant is a fundamental component that allows the blast furnaces to produce pig iron while reducing the environmental impact as much as possible. between 2008 and 2012 semat completed all works in reinforced concrete and part of the refractory works for eight plants of this type for ilva taranto.

Where the railroads take the slag, and the shifting engine is available for handling empty and loaded cars, this method is more economical for a single or even for a two-furnace plant than the liquid cinder method because it can be run by a single operator, whereas the other requires a locomotive and crew for two shifts as before stated.
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.
