The Impact

The submerged entry nozzle (SEN) clogging has been happening during continuous casting (or CC for short) for nonoriented silicon steel. To solve the problem, the paper studied a flow rate through SEN, a node attached to one of them, and the impact on the clogging. The results showed that when SEN is clogged seriously, the casting speed has to decrease below the target casting speed and that SEN clogging can be predicted by comparing the actual value and the theoretical one of a casting speed. Al2O3 and its composite inclusions caused the SEN clogging and the addition of Ca can solve SEN clogging during CC of the silicon steel both theoretically and practically. Furthermore, the impact of the addition of Ca on the magnetic properties of the steel were analyzed. The results showed that the core loss and the magnetic induction of the silicon steel decreased by using the addition of Ca, which generated more dissolved Aluminum, and the addition of Ca generated more harmful textures, which reduced the magnetic induction.

Two Sides

The effect of temperature on the recrystallization texture and microstructure of non-oriented silicon steel under asymmetrically rolling condition was quantatively studied using X-ray diffraction technology. The results show that the texture component accumulates around {111}<112> when annealed at 800°C. Texture intensity is high and grain size is uniformly distributed between 50μm and 100μm with best magnetism. When annealed at 850°C and 900°C, texture component is scattered and the grain size is also bigger. However, for the annealing at 750°C, the texture component is similar to cold rolled process. The grain size is small and non-uniform, which is unfavorable to magnetism. The difference of forces along the fast and slow side of the roller results in different deformation texture and further affects the intensity of recrystallization texture along the two sides of the roller.

High-silicon composite casting blank with the silicon content of 12wt% in core layer and with the silicon content of 3wt% in coating layer was fabricated by composite casting. The high-silicon steel composite sheet with smooth surface and good shape can be obtained by hot rolling and warm rolling. After high temperature diffusion and pickling process, the composite sheet with thickness of 0.44mm and homogeneous silicon content of 5.8wt.% could be achieved finally. The test results of magnetic properties show that the magnetic induction intensity B50and iron loss P15/50are 1.778T and 2.892w/kg respectively. It implies that the high-silicon steel composite sheet with high magnetic induction and low iron loss can be prepared by composite casting and rolling process.
