Dec 09, 2019· Furnace classification by heat source – Heat is generated in the furnace to increase the furnace temperature to a level which is higher than the temperature needed for the process, either (i) by the combustion of a fuel, or (ii) by conversion of electric energy to heat. Some furnaces also utilize the waste heat from the metallurgical process.

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.
A metallurgical furnace, more commonly referred to as a furnace, is a device used to heat and melt metal ore to remove gangue, primarily in iron and steel production. The heat energy to fuel a furnace may be supplied directly by fuel combustion, by electricity such as the electric arc furnace, or through induction heating in induction are several different types of furnaces used ...
Dec 09, 2019· 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 ...

Undreamt of metallurgical treasures. Slag and dross, which occur in significant amounts in every metallurgical process, have a very bad reputation as partially hazardous residues. Often rightly so, since the high heavy metal content does not allow its use as a mineral product.
So, not only the sensible heat of the liquid slag is lost, but it is also necessary to have an upstream slag drying unit for using the granulated BF slag in cement industry. Drying process normally consumes heat energy up to 72Mcal/ton of slag. Dry granulation of liquid BF slag is being developed in many countries along with heat recovery process.
