The FE-2100M silicon steel material measuring device is suitable for measuring various hot-rolled, cold-rolled oriented and non-oriented silicon steel materials, as well as the measurement of formed silicon steel transformer cores. It can accurately measure the magnetic induction intensity Bm, specific total loss Ps, hysteresis loop and AC magnetization curve of silicon steel materials under power frequency conditions.
Chinese Brandsilicon steel materialNote: The following thicknesses are mm.
1. Cold rolled non-oriented silicon steel strip (sheet)
Representation method: DW iron loss value (iron loss value per unit weight with a frequency of 50HZ and a sinusoidal magnetic induction peak value of 1.5T.) 100 times the thickness value of 100 times. If the DW470-50 represents a cold-rolled non-oriented silicon steel with an iron loss value of 4.7 w/kg and a thickness of 0.5mm, the new model is now 50W470.
2. Cold-rolled oriented silicon steel strip (sheet)
Representation method: DQ iron loss value (iron loss value per unit weight with a frequency of 50HZ and a sinusoidal magnetic induction peak value of 1.7T.) 100 times the thickness value of 100 times. Sometimes adding G after the iron loss value indicates high magnetic induction. If the DQ133-30 represents a cold-rolled oriented silicon steel strip (sheet) with an iron loss value of 1.33 and a thickness of 0.3mm, the new model is now 30Q133.
3. Hot-rolled silicon steel plate
Hot-rolled silicon steel plate with DR, according to the number of silicon content is divided into low silicon steel (silicon content ≤ 2.8%), high silicon steel (silicon content> 2.8%). Expression method: DR + iron loss value (unit weight iron loss value when the maximum value of magnetic induction intensity with 50HZ repeated magnetization and sinusoidal change is 1.5T) is 100 times +100 times of thickness value. Such as the DR510-50 said that the iron loss value is 5.1, the thickness of 0.5mm hot rolled silicon steel plate. The grade of hot-rolled silicon steel sheet for household appliances is expressed by JDR + iron loss value + thickness value, such as JDR540-50.
Japanese grade silicon steel material representation method:
1. Cold rolled non-oriented silicon steel strip is code-named A iron loss guarantee value by nominal thickness (expanded by 100 times) (expanded by 100 times when the frequency is 50HZ and the maximum magnetic flux density is 1.5T). For example, 50A470 indicates a cold-rolled non-oriented silicon steel strip with a thickness of 0.5mm and a guaranteed iron loss of ≤ 4.7.
2. The cold-rolled oriented silicon steel strip has a nominal thickness (expanded by 100 times) code G: for common materials, and P: for guaranteed iron loss of highly oriented materials (expanded by 100 times when the frequency is 50HZ and the maximum magnetic flux density is 1.7T). For example, 30G130 indicates a cold-rolled oriented silicon steel strip with a thickness of 0.3mm and a guaranteed iron loss value of ≤ 1.3.
Oriented silicon steel sheet is basically the 0.3 120,130 brand is more commonly used. The lower grade is 145,155 of the 0.35 series. The highest point is 110,100,105 of 0.27 thickness. The highest point is 085,080 of 0.23 thickness. From the performance of high magnetic induction low ordinary oriented steel.
Non-oriented silicon steel is basically more 0.5 thickness, followed by 0.35 and 0.65 two kinds of thickness. Sub-Senior high school low grade. The high grade is above 470 grade (the thickness is basically 0.35 and 0.5), and the medium grade is 470 grade (the thickness is basically 0.5). The low grade is 600-1300 grade (the thickness is basically 0.5 and 0.65). In addition, there used to be 1600 brands, which are rarely seen now.
For example, Baosteel B50A470 WISCO 50WW470 means no change 50 represents the thickness of silicon steel is 0.5MM 470 represents the maximum iron loss of silicon steel sheet is 4.7W represents non-orientation.
silicon steel sheetIt is a kind of silicon iron soft magnetic alloy with very low carbon content, and the silicon content is 0.5~4.5. The addition of silicon can improve the resistivity and maximum permeability of the iron, reduce the coercivity, core loss (iron loss) and magnetic aging.
silicon steel sheetClassification: Silicon steel armature sheet; Hot rolled silicon steel sheet
Hot-rolled silicon steel sheet is made by melting Fe-Si alloy in an flat furnace or an electric furnace, repeatedly hot-rolled into a sheet, and finally annealed at 800-850 ℃. Hot-rolled silicon steel sheet is mainly used in the manufacture of generators, so it is also called hot-rolled motor silicon steel sheet, but its utilization rate is low, energy loss is large, in recent years, the relevant departments have strong cold requirements to eliminate.
The most important use of cold-rolled non-oriented silicon steel sheet is for generator manufacturing, so it is also called cold-rolled motor silicon steel. Its silicon content is 0.5-3.0, and it is cold-rolled to the thickness of the finished product, and the supply state is mostly 0.35mm and 0.5mm thick steel strips. The Bs of cold-rolled non-oriented silicon steel is higher than that of oriented silicon steel; compared with hot-rolled silicon steel, its thickness is uniform, dimensional accuracy is high, and the surface is smooth and flat, thereby improving the filling factor and the magnetic properties of the material.
The main purpose of cold-rolled oriented silicon steel strip is for transformer manufacturing, so it is also called cold-rolled transformer silicon steel. Compared with cold-rolled non-oriented silicon steel, the magnetic properties of oriented silicon steel have strong directionality; it has superior high permeability and low loss characteristics in the rolling direction of easy magnetization. The iron loss of the oriented steel strip in the rolling direction is only 1/3 of the transverse direction, the magnetic permeability ratio is 6:1, the iron loss is about 1/2 of the hot rolled strip, and the magnetic permeability is 2.5 times of the latter.
High magnetic induction cold rolled oriented silicon steel sheet
High magnetic induction cold-rolled silicon steel strips are all single-oriented steel strips, which are mainly used in the manufacture of various transformers, chokes and other electromagnetic components in the telecommunications and instrumentation industries. Its application has two main characteristics: first, under the condition of small current, that is, weak magnetic field, the material is required to have high magnetic properties in the range of weak magnetic field, that is, high μ0 value and high B value; the second feature is the use frequency High, usually above 400Hz, even as high as 2MHz. In order to reduce the eddy current loss and the effective magnetic permeability under the alternating magnetic field, a thin strip of 0.05-0.20mm is generally used.
FE-2100M silicon steel material measuring deviceIt is suitable for measuring various hot-rolled, cold-rolled oriented and non-oriented silicon steel materials, as well as the measurement of formed silicon steel transformer cores. It can accurately measure the magnetic induction intensity Bm, specific total loss Ps, hysteresis loop and AC magnetization curve of silicon steel materials under power frequency conditions. Comply with GB/T3655-2000, GB/T13789-92 and IEC 60404-6.
silicon steel sheetThe iron loss of our material manufacturers, motor manufacturers and transformer manufacturers is a concern. According to China's industry standard (GB/3655-2008), Epstein square ring or standard magnesiometer (500SST/1000SST) is used as the basis for testing and evaluating the iron loss of silicon steel sheet. This method is the recommend use method of international IEC standard and national standard.
FE-30SST silicon steel sheet iron loss measuring instrumentThe use of small magnetic conductivity meter design (30SST) and reference to the international general magnetic conductivity meter test standards, through the other ring sample traceability value transfer, determine the effective magnetic path length, and complete air magnetic flux compensation, to meet the direct measurement of a single sample, the test is very convenient, and more accurate.
FE-30SST silicon steel sheet iron loss measuring instrumentThere is a big difference with similar products on the market at present. The single machine is equipped with a calibrated magnetometer to meet the measurement of oriented and non-oriented monolithic silicon steel, and to meet the more accurate measurement of the mass loss Ps and magnetic induction Bm of silicon steel sheet. It can be equipped with upper computer software, which can measure B- H hysteresis loop, u-H permeability curve and Ps-B loss curve. Under certain circumstances, it meets the full performance parameters of silicon steel strip samples tested by alternative square circle standards. It is a small and medium-sized silicon steel sheet using enterprises or universities with few samples, but it needs convenient and economical small-scale testing equipment under the condition of sample inspection.
