Title: Production of silicon steel sheet, and silicon steel sheet
Inventor: YAMAGAMI NOBUO
IPC: C21D8/12
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To provide a silicon steel sheet with low coercive force while obviating the necessity of decarburizing annealing and high-temp. long-time annealing, by specifying the amount of acid-insoluble Al in particular among components. SOLUTION: An investigation of secondary recrystallizability on various sheet thickness shows that a relationship is held among sheet thickness, amount of acid-insoluble Al, and magnetic properties. That is, in the case where the sheet thickness, (t)(mm), of a final cold rolled steel sheet and the amount of acid-insoluble Al, insol.Al (ppm), in a hot rolled steel plate satisfy the relation of insol.Al × t <= 8.0, a silicon steel having excellent characteristic of <=10.0A/m coercive force can be obtained. It can be speculated that, in the case where sheet thickness is large, surface energy reduces pinning due to fine inclusions such as alumina and sufficiently functions as a driving force for abnormal grain growth though its influence decreases with the increase of sheet thickness. Practically, preferred thickness of the final cold rolled sheet is <=0.4mm.

Filed: 1988-11-02
Abstract: PURPOSE:To prevent production of vibration and noise corresponding to a triangle wave frequency by using the sum of bipolar constant voltages and a random voltage for an input voltage to an integration device switched selectively. CONSTITUTION:When a summing voltage with a level being the result of summing a random voltage by a random voltage generator 31 to a positive constant voltage is applied to an integration device 2, the integration device 2 sends an integration output increased linearly through integration is sent from the integration device 2.

It is judged that a waterdrop does not exist when the height of the specific echo>the reference value G2, and it is judged that a large waterdrop or waterdrops in a large quantity exist when the height of the specific echo < the reference value G1.  When the reference value G1 < the height of the specific echo < the reference value G2, it is judged that a foglike small waterdrop exists. The judged result is output to a waterdrop removal device 5, and the device 5 can be controlled optimally according to a waterdrop stuck state.
