NUMERICAL RESEARCH ON THE OPTIMALIZATION OF THE CHEMICAL COMPOSITION FOR OLT 35K STEEL WITH A VIEW TO OBTAINING SUPERIOR MECHANICAL FEATURES AT HIGH TEMPERATURE

摘要

These results allow the establishing of the best C. Mn, Si contents from the chemical composition of OLT 35K, so that, /by the end of the elaboration, steel can possess certain imposed mechanical features. The analysis has been done for 3 elements of the chemical composition, being able to enlarge it for both other elements, depending on the desired chemical composition and other types of steel. Taking into consideration that the way in which one charge is done has a deep importance on the mechanical features of the steel, knowledge of these correlations is really significant for the engineer, because he is the one to estimate the values of the imposed parameter, depending on the chemical composition which allows him the adjustment of the chemical composition during the elaboration, in order to obtain the features desired by the beneficiary.
