Chinese brand representation method:
(1) Cold-rolled non-oriented silicon steel strip (sheet)
Representation method: DW+iron loss value (when the frequency is 50HZ and the waveform is sinusoidal, the magnetic induction peak value is the iron loss value per unit weight of 1.5T.)
100 times + 100 times the thickness value. For example, DW470-50 represents cold-rolled non-oriented silicon steel with an iron loss value of 4.7w/kg and a thickness of 0.5mm.
The new model is now represented as 50W470.
(2) Cold-rolled oriented silicon steel strip (sheet)
Representation method: DQ + iron loss value (the iron loss value per unit weight is 1.7T when the frequency is 50HZ and the waveform is sinusoidal. The magnetic induction peak value is 1.7T.)
100 times + 100 times the thickness value. Sometimes G is added after the iron loss value to indicate high magnetic induction. For example, DQ133-30 indicates that the iron loss value is 1.33 and the thickness is
0.3mm cold-rolled oriented silicon steel strip (sheet), the new model is now represented as 30Q133.
(3) Hot rolled silicon steel plate
Hot-rolled silicon steel plate is represented by DR. According to the silicon content, it is divided into low silicon steel (silicon content ≤ 2.8%) and high silicon steel (silicon content >
2.8%). Representation method: DR+iron loss value (when the maximum magnetic induction intensity using 50HZ repeated magnetization and sinusoidal change is 1.5T
100 times the unit weight iron loss value) + 100 times the thickness value. For example, DR510-50 indicates that the iron loss value is 5.1 and the thickness is 0.5mm.
Rolled silicon steel plate. The grade of hot-rolled silicon steel sheet for household appliances is represented by JDR + iron loss value + thickness value, such as JDR540-50.
