Re. t measuring process to check the resulting thickness of the rolled material

at the exit of a rolling mill and to influence the adjustment.

Dead hay registration concerns a measuring process, which is thereby is characterized by the fact that it is not the rolling stock that is measured, but the distance between the work rolls and that the impulse of the measuring device is used to adjust the setting of the stand accordingly to influence.

In rolling mills, especially in strip mills, it is customary to check the thickness of the rolling stock between the rolling mill and the reel-up and thereby correct the setting of the two work rolls in relation to one another accordingly. This method asked the stream part that already has an appropriate length between the rolling mill and measuring point too thick or thin material * It is therefore already unmaßhaltiges band _r been rolled is determined upon reference to the Meßvorriehtung that the tape strength is wrong and the appointing the work rolls must be changed in relation to each other «This results in a belt that is thinner or thicker in the shape of a staircase. According to the invention it is proposed not to measure the rolling stock at the exit of the rolling mill, but to transfer the position of the two work rolls to one another directly into a measuring device. Based on the display of the device, the adjustment and thus the roll gap can be changed accordingly by hand or automatically.

In Fig.l

the basic idea of the furnace described is shown in principle. Ss denotes (l) the work rolls (2) the entering and (3) the exiting rolling stock. .. 2 -

Subject · Measurement process ztiz * Examination of the resulting strength of the Rolled stock at the exit of a rolling mill and to influence the employment.

If the thickness and the hardness change, the rolling stock that enters (2) there is a change in the strokes of the rolling stock and thus a change in the deflection of the rolls in their longitudinal direction. bit Change in deflection attracts a change in strength of the emerging rolling stock after calibration. Will according to

a pair of heaters (4) attached to the work rolls (1), which both can slide or roll on the roll ball itself as well as directly next to the roll ball on a special ring track, so maeht this pair of sensors changes the movements of the rollers when Deflection of the same with "The movements of the pair of feet (4) transferred to a display device or to a switching device so Sound manual or automatic setting of the two work rolls «u · - can be changed accordingly.

In Fig. 3

in turn (l) denotes a pair of rollers, which on the hands with Running tracks (5) is provided · The sensors (6) for scanning the work rolls to each other are located in the middle of the vertical center of the Work rollers "

Fig. 4

shows a possibility of measuring the roll gap using compressed air. Ss in turn denotes (1) the work rolls, (7) a steel nozzle through blown compressed air into the roll gap by means of a hose (8) will. The compressed air can come from a container (9), with the air pressure by means of the pressure gauge (Io) is measured · When changing the Roll gap as a result of an increase or decrease in the strength or hardness of the incoming rolling stock changes the dynamic pressure that is in the outlet nozzle is located. The change in the dynamic pressure can be indicated by a pressure gauge or transmitted directly to a switching device * With the help of the visible display or the initiated switching movement, the adjustment of the work rolls to each other can be Can be changed manually or automatically *

Subject: measuring device to check the resultant strength of the « Rolled stock at the exit of a rolling mill and jsur influencing the employment.

There is a measurement rotation in which the sensor (U) from the outside to the Work rolls are created "Me measurement can be done in the lütt" of the roll bale as you take place on the belts according to Figure 3 * The two sensors transmit, for example, via the linkage (12) Movements on a display device (15) the movement of the display device or the movement of the sensor (U) can be on a Acting control that automatically changes the setting of the pair of whales to each other. According to

Fig. 6

A pair of nozzles (14) can also be placed on the outside of the work rolls, with the distance between the nozzles "a" changing accordingly when the rolling pressure is changed. The Anselge ~ and Forwarding of the changing roll gap takes place in the same way as in Fig. 4t
