INFLUENCE OF REFINING ON ACHIEVING LOW OXYGEN CONTENTS AT PRODUCTION OF SPECIAL STEELS FOR ENERGETIC INDUSTRY
Original language description
This paper deals with results of plant experiments aiming at achievement of low oxygen concentrations and high micro-cleanness during steel treatment for energetic industry on units of secondary metallurgy. Plants heats were aimed at analysis of influence of slag-making agents, wear of the lining, modification of inclusions, choice of mode of their out-stirring by the help of EMS and Ar blowing. Study of rules of formation, origin and conditions of elimination of non-metallic inclusions during steel treatment in ladle furnace ASEA-SKF was the aim of the experiments. Proper evaluation was made to determine oxygen concentration together with evaluation of micro cleanness according to DIN 50 602:1985 K4 and ISO 4967 Method A, namely on samples taken from the heel and under-head part of the forgings. Results present the oxygen concentration, number, ratio and analysis of chemical composition of non-metallic inclusions. Evaluation given in this paper presents the basic information on the achieved micro-cleanness at chosen refining technology. Results in this paper enable to point to the necessity of knowledge of the whole process of refining, which is crucial for achieving low oxygen concentrations and thus high micro-cleanness of steel.
