The complicated reactions are appeared in the liquid iron under the influence of interaction
parameters of basic and added elements during oxidation or addition of certain elements. These
reactions may explain the appearance some of phenomena during the production with the negative
consequences on the final material. Some phenomena as defects into external form are occurred,
while the motor power of certain processes in the liquid iron must be examined along with the
influence of interaction parameters at at temperatures 1523 - 1723 K. The investigations of mentioned
phenomenon are indicated that the interaction parameters affect on the quality characteristics of
produced material from such iron. The problem is that this region is not sufficiently tested and has so
little data about the interaction parameters of liquid iron for the specified temperatures.
Simultaneously the greatest liquidity preference of carbon is in the liquid iron. The interaction
parameters and parameters of surface stresses have got a large effect on the shape, size and
distribution during the formation the different forms of graphite in products from such liquid iron.
This paper tests the effects of the parameters of interaction, particularly Si to increase of C solubility,
the calculation of the amount of C solubility to saturation level of the melt with the carbon. These
phenomena or resulting castings defects are explained, discussed or may be interpreted from certain
aspects. It is important, therefore, that the attempt be more focused on the phenomenon of opposite
temperature effect and composition, as well as the interaction parameters or appearance of liquation.
The calculated interaction parameters are discussed, as well as the results obtained in the laboratory
and industrial scale
