IF Development thin hot-rolled silicon steel sheet

2 after the 8 sets were rolling, rolling after the second folding 4)} strict control of two, four sets rolling reduction ratio after the first, to ensure the basic stick, can not have a clear opening, folding after the first permit conditions in the device, the appropriate reduction rate increases, guaranteed to stick. After more than 100 tons of finished product rolling, could not result in bond breaking and local sticky situation, though not completely avoided, but can be controlled within the 1O, finished product rate can reach 65 to 70, with more rolling process is basically successful. Test results have been mass Pán 4, 100 tons of finished thickness tolerance in the 0.23 ~ 0.27mm, with the board difference ≤ O. 03mm, Table 2 lists the performance of groups of products the situation.

Table 3 lists the 0.35ram Japanese high-grade cold-rolled non-oriented silicon steel sheet tt10, H9, and hot-rolled silicon steel DR1750G-35 high typical data.

When the 1000Hz, RTH250 the lowest unit of iron loss. Was found in the same time, RTH250 strength of the magnetic confusion should be the best,[link widoczny dla zalogowanych], especially in the larger gap between the strong magnetic field, indicating RTH250 have a higher saturation flux density of the island (RTH wind is 2.04T, DR1750 ~ 35 to 1.95T) . The above data shows, RTH250 can be replaced in the 400ttz H10, tt9 and DR1750G a 35 to use. Frequency of 1000Hz over the use of motors, electrical products, RTH250 is the best core material. The material used by the user works well, selling products for the market. We also RTH250 were a total loss of P loss and eddy current hysteresis loss P.

Will account for 85.5%, but the new development of the thin hot-rolled silicon steel sheet RTH250 shouted through the thickness and resistivity to 0.25 Yeh 0.50Q · m above the increase cut the throat (usually silicon steel for the 0.42N0.46Q · m) , so that eddy current loss has been reduced significantly,[link widoczny dla zalogowanych], while there is a certain hysteresis loss reduction, so that the total loss to a lower level.
