AbstractIn this work, silicone oils of different viscosities were used to simulate slag foaming. The experimental results showed that the variations of foaming height with superficial gas velocity and liquid viscosity do not show simple increasing trends.

Suppression of slag foaming by a sound wave
Ultrasonics Sonochemistry, 2000 The aim of this work was to study the effects of sound frequency, sound intensity and viscosity of slag on the slag foaming rate and the steady-state foam height. Experiments were carried out using two slags (BaO-B2O3) melted at a temperature of 1223 or 1273 K, as well as water-glycerin solutions at room temperature.

Physicochemical properties of foaming slags
International Materials Reviews, 2004Molten slag foams can be considered very dynamic (non-equilibrium) systems, hence their behaviour in industrial processes can be difficult to predict and control. This paper reviews the role of physicochemical properties of molten slags, and the types of stability mechanisms likely to be operating in slag foams.

Composite foamed alkali-activated concrete with slag and steel slag
Magazine of Concrete Research, 2020Thermally expandable foaming microspheres (FMS) are used as a foaming agent in many different fields due to their excellent dimensional stability and elastic properties. In this study, lightweight thermal insulation materials were prepared by adding FMS to foamed concrete containing alkali-activated steel slag and blast-furnace slag.

Effect of temperature on slag foaming
Metallurgical and Materials Transactions B, 1995Slag foaming has become important not only for the modem electric arc furnace but also for basic oxygen steelmaking and new ironmaking processes, such as bath smelting. In the electric arc furnace, foaming practices are widely used to shield the refractories from the arc and to protect metal from the atmosphere.

Slag foaming measurements in terms of the foaming index (∑) were conducted on bath smelting-type slags (CaO-SiO2-FeO, CaO-SiO2-MgO-Al2O3-FeO) at 1773 K. It was found that the slag foam stability decreases with increasing FeO (FeO > 2 pct) content and basicity. For the slag system (CaO-SiO2-FeO), no stable foam was observed at very low FeO content (

Slag Foaming in an Electric Arc Furnace
ISIJ International, 2009 Slag foaming in an electric arc furnace (EAF) is examined using a mathematical model of the EAF to compute the CO generation rate and slag chemistry and laboratory measurements of the foam index. The foam height limited by either the foam stability or from the amount of slag present was computed for a high productivity furnace using relatively large ...
