Hot-rolled silicon steel plate with DR said that according to the number of silicon content is divided into low-silicon steel (silicon content ≤ 2.8%), high silicon steel . Representation: DR + iron loss value (50HZ repeatedly used by the sinusoidal-shaped magnetization and changes in magnetic induction at the maximum for the 1.5T
Unit weight of the iron loss value) + thickness of 100 times the value of 100 times. DR510-50 said that if the core loss value of 5.1, thickness of 0.5mm heat
Rolled silicon steel plate. Household appliances with the grades of hot-rolled silicon steel sheet with the value of iron loss JDR + + thickness values that if JDR540-50.

2, the Japanese brand that method:
(1) cold-rolled non-oriented silicon steel with the nominal thickness (100-fold expansion of the value) +, code-named A + iron loss to ensure that value (the frequency of 50HZ, the largest
1.5T magnetic flux density for the iron loss when the value of the expansion of 100 times the value of after). 50A470 expressed as thickness of 0.5mm, a value of iron loss guarantee ≤
4.7 with cold-rolled non-oriented silicon steel.

4.7 with cold-rolled non-oriented silicon steel.
(2) cold-rolled silicon steel with the direction from the nominal thickness (100-fold expansion of the value) +, code-named G: that ordinary materials, P: that the high orientation of
+ Iron loss material to ensure that value (the frequency of 50HZ, maximum flux density of 1.7T at the time of the expansion of iron loss values after 100 times the value). If 30G130
That the thickness of 0.3mm, core loss value of ≤ 1.3 to ensure that the cold-rolled silicon steel belt orientation.
Fourth, electroplating tin plates and hot dip galvanized sheet:
1, plating tin plate
Tin plating steel sheet and strip, also known as tin, which plate (with) the surface of the tin-plated, have a good corrosion resistance, and non-toxic, Can be used as packaging material, skin care both within and outside the cable, telecommunications instrument parts, a flashlight and other hardware
