Title: Method for controlling tension on metallic strip in cooling zone of continuous heat treating furnace
Inventor: SUGIYAMA KENJI
IPC: C21D9/573
Filed: 1983-07-13
Abstract: PURPOSE:To maintain the constant tension to be exerted on a steel strip in the stage of cooling the steel strip, etc. with cooling rolls by correcting the number of revolutions of the cooling rolls after the moving roll on the uppermost stream in controlling the cooling rate with the movement of the moving rolls among the cooling rolls. CONSTITUTION:A steel srip S having a high temp. is passed between stationary cooling rolls 1, 3, 5 and vertically movable rolls 2, 3 and is thereby cooled in the stage of cooling the strip S in a cooling zone 6 of a continuous heat treatment furnace. The temp. of the steel strip after cooling is measured with a thermometer 10 at the outlet of the zone 6 in this stage and the rolls 2, 4 are moved upward or downward according to the result thereof to change the contact area of the strip S with the rolls 1-5, thereby adjusting the cooling effect. The tension to be exerted on the strip S changes with the vertical movement of the rolls 2, 4 in this stage and therefore the change with time of the pass length L' (L0+L1+L2) of the steel strip between the adjacent rolls 1 and 2 is determined from the relation with the moving distance L of the roll 2 and the rotating speed of the rolls 2-5 is controlled, thereby maintaining the specified tension to be exerted on the steel strip and preventing the slackening and rupturing of the steel strip.

Abstract: PURPOSE:To detect a training signal which contains a necessary sequence for >=2 periods, by using a data point where an autocorrelation function becomes an impulse as an element. CONSTITUTION:A demodulated training signal is inputted to a delay line 7. The 1st correlating circuit 8 finds and outputs the ssquare-sum (b) of the distance between a data signal on the delay line and the correction value in a sequence M.

The sequence M of the 2nd correlating cirucit 9 is initialized by the peak value of the 1st correlating circuit 8 and rotated synchronously with an input signal. The output of the 1st correlating cirucit 8 is divided by the output of the 2nd circuit 9 to find a high-level signal (d) with a period L, thereby detecting the signal which contains the sequence M for >=2 periods.
