The type of silicon steel sheet silicon steel plate
It is made of cold-rolled silicon steel with silicon 0.8%-4.8% as material.There are two kinds of steel strip with no grain orientation and grain orientation in cold rolled silicon steel sheet. The cold rolled electrical steel strip has the characteristics of smooth surface, uniform thickness, high stacking coefficient, good punching quality, etc., and the magnetic sense is higher and the iron loss is lower than that of the hot-rolled electric steel band. Instead of producing hot rolled motor or transformer with cold strip, its weight and volume can be reduced by 0%-25%. If the cold rolled oriented belt, better performance, use it instead of hot-rolled or cold-rolled low grade, can reduce the power consumption of the transformer 45%-50% transformer, and more reliable performance.Used in manufacturing motors and transformers. Generally, the grain oriented cold rolled strip is used as an electric motor or a welding transformer, etc. the grain oriented cold rolled strip is used as an iron core for a power transformer, a pulse transformer, and a magnetic amplifier.
Hot rolled silicon steel sheet (GB5212-85) for electrical purposesThe hot rolled silicon steel sheet for electrical purposes is made of a soft ferromagnetic alloy with low carbon content, which is rolled into a sheet with a thickness of less than 1mm. Hot rolled silicon steel sheets for electrical purposes, also called hot rolled silicon steel sheets.Hot rolled silicon steel sheet according to the combination of silicon content can be divided into low silicon (Si = 2.8%) and high (Si = 4.8%) of silicon steel sheet two.
Hot rolled silicon steel sheet (GBH46002-90) for household appliancesThe grades of hot-rolled silicon steel sheets for household appliances are expressed in J (home) D (electric) R (hot rolled), i.e. JDR. After JDR, the number is iron core value *100, the line number is the steel plate thickness (mm) *100. The electromagnetic properties of hot rolled silicon steel sheets for household appliances can be slightly lower, and the minimum value of iron loss (P15/50) is 5.40W/kg. General delivery without delivery.Used in all kinds of electric fans, washing machines, vacuum cleaners, hoods and other household appliances such as differential motors.
