(1) cold rolled non-oriented silicon Steel belt (sheet) representation method: dw+ Iron Loss value (at a frequency of 50HZ, the waveform is sinusoidal magnetic sense Peak is 1.5T unit weight iron loss value. ) is 100 times times the thickness value of 100 times times.
If dw470-50 indicates that the iron loss value is 4.7w/kg and the thickness is 0.5mm cold rolled non-oriented silicon steel, the new model is expressed as 50w470.
(2) Cold rolled oriented silicon steel belt (sheet) representation method: dq+ Iron Loss value (at a frequency of 50HZ, the waveform of the sinusoidal peak of the magnetic sense is 1.7T per unit weight iron loss value. ) is 100 times times the thickness value of 100 times times. Sometimes the iron loss value is followed by G to indicate a high magnetic sensation.
If the DQ133 indicates a iron loss value of 1.33 and a thickness of 0.3mm cold-rolled oriented silicon steel strip (sheet), the new model is expressed as 30q133.
(3) Hot-rolled silicon steel sheet hot-rolled silicon steel plate with Dr said, according to the amount of silicon content into low-silicon steel (silicon-containing ≤2.8%), high-silicon steel (silicon content > 2.8%). Representation: The dr+ Iron loss value (100 times times + thickness value of 100 times times the unit weight iron loss value with 50HZ repeated magnetization and the maximum magnetic induction intensity change by sinusoidal shape). For example, dr510-50 a hot-rolled silicon steel plate with a iron loss value of 5.1 and a thickness of 0.5mm. The grades of hot-rolled silicon steel sheets for household appliances are expressed in jdr+ iron loss + thickness values, such as jdr540-50.
