This study is focused on the effects of electroslag remelting by prefused slag (CaO, Al2O3, and CaF2) on macrostructure and reduction of inclusions in the medical grad of 316LC (316LVM) stainless steel. Results showed that in order to obtain uniform ingot structures during electroslag remelting, the shape and depth of the molten pool should be carefully controlled. High melting rates lead to de...

The influence of Ca treatment, Mg treatment and Ca–Mg combined on the inclusions in 45MnVS non-quenched tempered steel were studied present work. After melting experiment, a hot rolling test was carried out ingot. Additionally, composition, quantity morphology samples analyzed by automatic scanning electron microscopy (ASPEX) an energy dispersive X-ray spectrometer connected to microscope (SEM-...

The paper presents numerical modelling and an operational experiment to forge a slab ingot P40N from 55NiCrMoV7 tool steel the procedure for optimization of its production. aim simulation forging was verify existing plate conventional polygonal 8K with shape surfaces. effect on achievement required reduction strain after cross section plate, final dimensions approximately 1010 mm width × 310 th...

Abstract Segregation is an unavoidable phenomenon in continuous or ingot casting of steel for thermodynamic reasons. If costly processes that explicitly reduce segregation are not carried out, the segregations remain until final product. Therefore, understanding development and effects along entire process chain necessary. The focus this publication on treatment low alloy steels. First, charact...
