“…In addition, AlN [3] and complex Al 2 O 3 -MnS/AlN inclusions with undesirable characteristics/distribution are detrimental to the magnetic properties. [4] In contrast, silicate-type inclusions are soft and deformable during rolling as well as deep drawing operations. Therefore, Si deoxidation is employed in many steel grades (long products), for instance, thin wire, springs, [5] and electrical steel, [3,6] to get the desired inclusion characteristics.…”

Si–O deoxidation equilibria in liquid steel are not reliably known, especially in the high silicon concentration range. Herein, Si–O deoxidation equilibria in liquid steel at 1823–1873 K have been investigated for a wide range of silicon concentrations. Thermodynamic analysis was carried out using Wagner's interaction parameter formalism (WIPF) and FactSage 8.1. The first and second‐order cross‐interaction parameters estimated at 1873 K are as follows: , , . Moreover, nonmetallic inclusion characteristics were also investigated for varying silicon concentrations.

“…Electrical energy is indispensable for the development of modern society. Nowadays, low-carbon, energy-saving and environmentally friendly products are required for the sustainable development of modern society; this requires the manufacturers to provide better energysaving, larger capacity, higher voltages and reduced emission transformers and electrical machines [3]. To obtain the superior magnetic properties, the texture microstructure called Goss-oriented grains with a crystalline direction of (110) and <001> should be developed [4].…”

Grain-oriented electrical steel (GOES) has been used for many years for application in transformed cores due to its excellent magnetic properties. Magnetic properties are strongly influenced by obtaining a texture with a certain orientation (110) [001] for BCC structure. This is related to the easy direction of magnetization [001]. So far, the main research has been focused on obtaining a strong texture in the last stages of the process. The aim of the present study was to additionally trace textural changes for a slab after the continuous casting (CC) process and for a sheet after the hot rolling process. The scope of such an analysis has not been conducted before. With regard to the state after continuous casting (CC), the texture was related to measurements of the anisotropy of Barkhausen magnetic noises and the macrostructure of the slab. Based on the X-ray diffraction examinations that compared the texture intensity calculated from the texture coefficient of the slab, the hot rolled steel and the final product of grain-oriented electrical steel contained 3.1% of Si. The studies performed with the material taken from three different production steps showed high differences in the values of textural intensity indicating the occurrence of a crystallization texture, especially in the area of the columnar crystal zone; textural weakness after the hot rolling process and high texturing in the final product for textural components corresponding to the desired Goss texture.

“…Contemporary grain-oriented electrical steel (GOES) is a composite material that contains Fe-3%Si and has a ceramic metal film known as “the glass film” serving as an insulation coating (IC) [ 1 , 2 , 3 , 4 , 5 ]. The main purpose of IC is to create an isolation layer between sheets of magnetic cores.…”

Ceramic insulation coating (glass film) is an important constituent of grain-oriented electrical steel (GOES) designed for use in transformers. Within the scope of this study, the glass film was obtained by means of interaction between the surface of GOES containing 0.5 wt. % Cu and a heat-resistant MgO coating during annealing up to 1100 °C in the 75%H2 + 25%N2 atmosphere. The structure of glass film was analyzed using X-ray diffraction, glow-discharge optical emission spectroscopy, scanning probe microscopy, scanning electron microscopy, differential scanning calorimetry and thermodynamic calculations. After annealing, the glass film contained the following phases: crystalline (MgFe)2SiO4 and amorphous Fe-based solid solutions. The multi-stage mechanism of the glass film formation on GOES surface during high-temperature annealing was determined.
