Abstract: PURPOSE:To improve the accuracy of final sheet thickness by analyzing the differences between a rolling load and a sheet thickness at the time of biting a material to be rolled by the 1st stand of finish rolling, and their estimated values, and correcting the set values of the succeeding stands. CONSTITUTION:The sheet thickness, sheet width, and sheet temperature of a material to be rolled at the outlet side of a final stand R of rough rolling and the sheet temperature at the inlet side of the 1st stand F1 of finish rolling are measured respectively. Calculations are performed basing on these measured values, and the setting of respective rolling stands F1-6 are finished before the arrival of the material to be rolled at the stand 1. Next, a draft position, a rolling load, and a forward slip at the time of biting the material by the stand F1, and a sheet thickness at the outlet side of stand F1 are measured respectively. The actual values of correcting factors are calculated by using these measured values to correct the estimated values of rolling loads of the stands F2-6 which are estimated at the time of setting calculations. At the same time, the actual values of gaugemeter constants are calculated by using the measured values of the draft position, rolling load, and outlet-side sheet thickness of stand F1, and the gaugemeter constants of stands F2-6 are corrected. The set values of draft po sitions of stands F2-6 are corrected basing on these corrected constants and that estimated value of corrected rolling load.

Title: Transition type plasma torch
Inventor: INOKUCHI KAZUNARI
IPC: H05B7/00
Filed: 1990-08-08
Abstract: PURPOSE:To prevent a negative electrode from oxidation wearing by applying an alternating current magnetic field to a plasma column from outside to form reversing electromagnetic force in the plasma column by interlinkage of the field with a current flowing inside the plasma column, and reversing the plasma itself. CONSTITUTION:A coil 10 is arranged at the top end of a nozzle 3 so that a magnetic field is formed around the top end of an negative electrode 2, and a coil power supply source 11 to alternating current excite the coil 10 is provided. A plasma arc 6 is generated between the top end of the negative electrode 2 and a heated object 5 and, when an alternating current is fed to the coil 10 wound around an outside periphery of the nozzle 3, an electric current inside the plasma arc 6 is interlinked with magnetic flux of an alternating current magnetic field. Consequently, electromagnetic force is generated in the plasma arc 6 and a plasma column main body starts reversing. In the reversal plasma thus formed, an eddy current in the constant direction is not formed and an area of pressure lower than the circumference is therefore difficult to be generated, thus preventing drag-in of the outside air. According to this constitution, a plasma equivalent to a turning plasma is formed and oxidation wearing of the negative electrode 2 is prevented.
