Classification and application of silicon steel
Hot rolled silicon steel sheetHot rolled silicon steel plate with DR said, according to the number of silicon content into low silicon steel (silicon containing less than 2.8%), high silicon (silicon content > 2.8%). Method of expression: DR+ iron loss value (using 50HZ repeatedly magnetized and sinusoidal variation of magnetic induction intensity maximum value of 1.5T when the unit weight, iron loss value of 100 times + thickness value of 100 times). For example, DR510-50 represents a hot rolled silicon steel sheet with a core loss of 5.1 and a thickness of 0.5mm. The grades of hot rolled silicon steel sheets for household appliances are expressed as JDR+ iron loss value + thickness value, such as JDR540-50.
Cold rolled oriented silicon strip (sheet)Said method: DQ+ iron loss value (in frequency 50HZ, sinusoidal waveform, magnetic induction peak is 1.7T per unit weight, iron loss value) 100 times the thickness value of 100 times. Sometimes the core loss plus G indicates high magnetic induction. For example, DQ133-30 represents a cold rolled silicon strip (sheet) with a minimum iron loss of 1.33 and a thickness of 0.3mm. The new model is expressed as 30Q133.
Said method: DW+ iron loss value (in frequency 50HZ, sinusoidal waveform, magnetic induction peak is 1.5T per unit weight, iron loss value) 100 times the thickness value of 100 times. For example, DW470-50 represents a cold rolled non oriented silicon steel with a core value of 4.7w/kg and a thickness of 0.5mm. The new model is expressed as "50W470".
