Abstract
Abstract Slag refining slag with west materials was analysed used the DTA methods. In the paper a method of determining the reduction capability, with the Carbo-N-Ox method, of slag solutions was used. Some relations between the stimulators in the environment - slag - metal system allow to initiate mass exchange reactions in the process of slag refining.The presented in work course of behaviour permits on choice of basic composition of slaglite, the of necessary components stimulating quantities, as well as on accomplishment of opinion of ability refinement. The worked out programme Slag-Prop, after introduction of data with experiment, it allows on next corrections in composition of proposed mixtures also, should be put on properly elaborated factors of multistage reaction with essential usage of suitable stimulators.
Highlights
Quality of the alloy depends on the composition of slag properties
In the scientific works [1, 2, 3] there were analyzed the properties of the stimulating compounds in the system M - Z - St - WN - A: substances that stimulate are considered to be more stable than the oxides, which favors the possibility of improving the viscosity of slag z, lowering its melting temperature TT, and providing high speed response in the gas phase
The analyzes showed the possibility to compound slag with substances such as fluorides (e.g. NaF, CaF2) [1, 3, 4] which increase the participation of simple anions at the expense of the weakening of bonds of complex anions, which should favor the exchange reaction
Summary
Quality of the alloy depends on the composition of slag properties (viscosity, surface tension, liquid, wetting angle). The analyzes showed the possibility to compound slag with substances such as fluorides (e.g. NaF, CaF2) [1, 3, 4] which increase the participation of simple anions at the expense of the weakening of bonds of complex anions, which should favor the exchange reaction. It is worth to pay attention to the sustainability fluorides as they are more stable than the oxides of K, Na, Mg, Ca, Mn, Ti, Zn, Cu, P, B, Fe [3] This gives us the possibility to use reaction (5) of the slag type:
