Heat recovery from slag improves energy efficiency of furnaces

Granulation of slag Slag previously discarded, has commercial . value when processed into the right form, but must be cooled down in a controlled manner to achieve the required properties. Several processes have been developed to process the slag and recover heat in the way needed. One of the most obvious systems is the production of steam or hot water for use in power generation or industrial

Crystallization Behaviors of Blast Furnace (BF)

Blast furnace (BF) slag is the principal byproduct formed during the iron-making process, which generates a considerable amount of thermal energy. However, to simultaneously recover the maximum amount of residual heat and obtain vitreous slag using a low conduction coefficient of air is a primary challenge of the dry granulation technique, which has not been solved by either fundamental

Utilization of ironmaking and steelmaking slags

- slag granulation process, - other processes. slag pit process the slag pit process involves pouring of molten iron into slag pit where slag develops crystalline structure by process of controlled cooling. the slag pit can be constructed adja-cent to the blast furnace or be in an other remote place. in the second case slag ladles are used for molten slag transport. Cooling time in the pit is

CFD modelling of dry slag granulation using a novel

CSIRO's dry slag granulation process. The 2D CFD model can be used to give timely predictions that allow one to explore and select appropriate design and operating conditions for producing a slag film that will ultimately break up into droplets of desired size; and the 3D CFD model can then be applied to predict the size distribution of these droplets. The relatively efficient nature of the

THE DRY BLAST- FURNACE SLAG GRANULATION AS RESOURCE

The Redcar and Davy Dry Slag Granulation Process (Great Britain) is analysed as the example of the dry granulation arrangement. Traditionally the liquid slag is atomized by high pressure water jets which impinge on the slag stream as it leaves the runner. The rapid cooling produces the glassy structure which is necessary for cement making. In Donetsk there is 300000 tonne of the molten blast

Thus, the physical properties of the slag are simplified as constants and their values at 1 500°C are adopted at all simulations in this paper. The heat transfer and temperature distribution during this granulation period are really insig- nificant. Therefore, the subsequent part of this paper focuses only on the granulation

In order to simulate the process of steel slag granulation, a set of equipment was made as shown in Figure 1. This consists mainly of launder, granulation tank, dewatering tank, waste water tank and fresh water tank. Solid steel slag obtained from PT. Krakatau Steel was melted in an induction furnace at 161DOe and then transferred and poured into the launder to which water was sprayed on the
