Title: Looper control method and loop car control method
Inventor: TAKAYANAGI SEIJI
IPC: B21B15/00
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To prevent generation of strip walk inside a looper in the case of excessive accumulation of steel sheets in the looper on an entrance side. SOLUTION: With the accumulating quantity of a steel sheet in the entrance side looper 4 reduced normally, the accumulating quantity (length) is calculated in the entrance side looper 4 while its entrance side section is stopped, in accordance with a welding speed for a steel sheet 21 to be connected to the next and with an accumulating quantity or the like inside the present entrance side looper 4; accumulation is started when the remaining length of the steel sheet 21 by the instrument 35 for measuring the remaining length of a payoff reel coil reaches the calculated accumulating quantity; 4 after the accumulation of that quantity, the travelling is stopped for the steel sheet 21 on the entrance side looper 4, with welded connection made to the next steel sheet and then, the steel sheet is run at the original speed.  Since the accumulating quantity increases only just before the stopping, it prevents strip walk from generating in the looper.

IPC: H02M7/17
Filed: 1986-04-18
Abstract: PURPOSE:To eliminate current unbalance of a converter, by correcting the phase difference component of an automatic phase shifter. CONSTITUTION:An electric valve such as thyristor is connected in bridge to from an AC/DC converter, and the two or more AC/DC converters are arranged in parallel to constitute a DC large-capacity power source. In a control circuit of the power source, in order to prevent current unbalance of each converter due to impedance difference including a transformer and a cable at secondary side, phase correction signal is applied to input signal section of automatic pulse phase shifters APPS1-n to determine phase of each converter. In this case, a thermo sensor and a frequency detector V/F are installed. Thereby the thermo sensor detects temperature at periphery of the control circuit, and the frequency detector V/F detects frequency of the AC power source. Receiving these detecting signals, the phase correction circuit outputs correction signal to correct phase difference in the automatic pulse phase shifters APPS1-n. As a result, output voltage of each converter becomes the same and the current unbalance is eliminated.
