Crystallization Behaviors of Blast Furnace (BF) Slag in a ...

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 ...

Granulation of molten slag for heat recovery - IEEE ...

The purpose of this paper was to study slag granulation for promoting heat exchange between slag and gas. In the experiment, the influence of the rotating speed and the shape of the cup on the slag drop size was mainly examined. The slag drops outward to the cup lip were collected by the receiver with separations and examined from viewpoints of ...

Feasibility of Rotary Cup Atomizer for Slag Granulation

glass structure is required. The granulation of slag is need-ed to make uniform glassification due to its low thermal conductivity. The point is that the dry slag granulation with quenching is necessary to solve the problems above men-tioned because it keeps slag property as a raw material of cement. Furthermore, it is expected that slag ...

The centrifugal atomization process of liquid by a spinning disk has been investigated by visualized experiments. First, the nondimensional critical equations are derived theoretically and obtained from the experimental data. Accordingly, a transition map is proposed to analyze the effects of operating conditions (liquid flow rate Q, angular speed ω, and disk diameter D) and liquid properties ...

Slag Cement Questions

Slag cement is the hydraulic cement that results when molton slag from an iron blast furnace is rapidly quenched with water, dried and ground to a fine powder. The rapid quenching ("granulation") "freezes" slag cement in a glassy state and imparts cementitious properties to the product when ground finely.

Current and Future of Dry Centrifugal Granulation Process

Abstract: Based on the comprehensive experimental test-bed of blast furnace slag waste heat recovery, we study the impacts which are caused by the changes of the key parameters, such as blast furnace slag discharged temperature, the speed of the granulation device, on the particle diameter distribution and sphericity, so as to master the best operating parameters of the blast furnace slag dry ...
