Annealing Experiments

A high grade non-oriented electrical steel final annealing product was processed by stress relief annealing experiments under pure hydrogen atmosphere using different process parameters. The samples were compared in the aspects of magnetic properties and anisotropy, then analyzed the phenomena concerned with grain size, texture and precipitates aspects. The experiments showed that the samples magnetic properties were most improved in the 850 degrees stress relief annealing experiment, thus providing a reference method for non-oriented silicon steel stress relief annealing experiments and to obtain low core loss non-oriented silicon steel.

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.

Hot Rolling Process

There are always differences between the magnetic properties (core loss and magnetic induction) of the head and those of the tail, with the same chemical composition, in a medium-grade non-oriented silicon steel coil (or MGNO for short). To work out the reason leading to the differences and get methods to increase the magnetic properties, this paper studied the types and the distribution of the inclusions in MGNO, and the effects of the inclusions on the magnetic properties of the MGNO, by using SEM + FEEM observation and statistic analysis. The results show that there are oxide inclusions, sulfide inclusions, nitride inclusions and composite inclusions in the MGNO. More inclusions shorter than 500 nm are bad for the magnetic properties of the MGNO. On a lower order of the sizes, the number of the inclusions would more obviously affect the MGNO on its magnetic properties. The Al2O3 shorter than 1 µm and the MnS whose size is 100∼500 nm are the main inclusions that decrease the magnetic properties of the MGNO. In order to get better magnetic properties of the MGNO, the steelmaking process and the hot rolling process should be improved, chiefly the RH and the heat furnace.
