Managing Technological Properties of Mould Fluxes.
Physico-chemical properties of mold fluxes greatly influence fundamental processes as lubrication of strand and the mold wall. Balance of these effects should be achieved for better quality and smooth casting operations of crack sensitive steel grades. Design special fluxes matching such critical requirements has been definitely a stiff problem. In this work viable solution of such technological puzzle is discussed. Some experimental evidences strongly support the effectiveness of the proposed approach to the problem. Paper published on I&SM Vol. 25 (6) June 1998 pp.43-46
Fluxes Design in Advanced Thermal mould Monitored Environment.
Considering that critical applications in modern steel casting started to be carried on by means of advanced thermal monitoring systems, mold fluxes performance requirements will be more and more demanding. It has been developed an original method of designin mold fluxes which correlates heat flux density profiles as obtained by mold thermal monitoring to some chemical physical characteristics of fllux, thought to have a key role in determining thermo-physic properties of slag film.

Any Change of Controlling Crystalization Behavior of Mould Fluxes? New Insights.
Crystalizations of MnO-doped and un-doped mold fluxes at different cooling rates was investigated to study peculiar chemical-physical effects induced by this transition metal oxide. By DTA analysis relationship between onset of crystalization and cooling rate was evidenced. Crystalization temperatures calculated by extrapolation for cooling rates approaching zero were found quite similar to equilibrium break temperatures determined with hight temperature rotational viscosimetry.
