Pilot trials testified that by the main characteristics of chemical composition, micro- and macrostructure, and mechanical properties of the manufactured bars, the metal of ingots from 15Х11МФ (15Cr11MoV) steel, melted under the developed slag ANF-39 (32CaF2/31Al2O3/30CaO/4MgO/3SiO2), is highly competitive with the products, remelted using slag ANF-6 (70CaF2/30Al2O3), which is applied in batch production by the current technology. Compared to slag ANF-39, application of slag ANF-6 allowed reducing oxide inclusion content by 0.5 points and power consumption at electroslag remelting by 17 %; the slag is more eco-friendly due to lowering calcium fluoride content more than 2 times; the cost of materials for slag production was reduced by 23…25 %. Slag ANF-39 is recommended for replacement of ANF-6 for ESR of alloyed and high-alloyed steels in stationary and short-collar molds. Ref. 8, Tabl. 5, Fig. 4. [ABSTRACT FROM AUTHOR] |
