Grain-oriented electrical steel (GOES) has been used for many years application in transformed cores due to its excellent magnetic properties. Magnetic properties are strongly influenced by obtaining a texture with certain orientation (110) [001] BCC structure. This is related the easy direction of magnetization [001]. So far, main research focused on strong last stages process. The aim present study was additionally trace textural changes slab after continuous casting (CC) process and sheet...
Improvement of magnetic properties electrical steel can be achieved by reduction the size domains. The application local stresses through laser scribing leads to reduced core losses. In order determine effect refinement conditions domains on soft material, four samples with a thickness 0.23 mm were refined. each sample was carried out using different line energies beam. Estimation domain performed Jeffries method, viewer used reveal structure. measurement at frequency 50 Hz and an induction...
This paper presents an analysis of non-metallic inclusions occurring in high-silicon steels containing about 3% Si terms their type, volume fraction and morphology. The were divided into 3 main groups: oxides, sulfides, nitrides which together can also form complex. work was based on numerous metallographic observations two sections (longitudinal transverse to the rolling direction). study performed three casts differing chemical composition. analyzed characterized by a different content...
Hot rolling of grain-oriented high silicon steel is related to technical problems such as temperature andlong campaigns with strips the same width. Numerous methods may be carried out a solutionto these problems. Before campaign, all rolls finishing stands are exchanged. The campaign isscheduled additional exchanges on two last in stages. A roll’s wear increases thequantity rolled material and lead strip profile deformation. Exchanging ensures requiredsteel quality prevents losses caused by...
