technical field

The utility model relates to the field of metallurgical measurement, in particular to an on-line detection device for the width of a galvanized steel strip.

Background technique

At present, the galvanizing line does not have an online detection of the width of the strip. Since the width of the strip affects the use of high-end products, in order to ensure the consistency of the width of the strip, it is necessary to detect the width of the strip. The quality inspector uses a steel tape to measure Strip width, this detection method cannot control the detection accuracy very well, and cannot meet the quality requirements of high-end products. Moreover, this detection method has slow detection speed, low work efficiency, and requires a lot of human resources.

Utility model content

The technical problem to be solved by the utility model is to provide an on-line detection device for the width of the strip steel which can effectively detect the width of the strip steel on-line in real time.

The technical scheme adopted by the utility model to solve the technical problem is: the on-line detection device for the strip width of the galvanized line, which includes a tension roller and a steering roller arranged on the galvanizing line, and is characterized in that: between the tension roller and the steering roller Light source detectors are oppositely arranged on both sides of the steel strip along the transverse direction of the steel strip.

The light source detector is composed of a light source transmitter and a light source receiver respectively arranged on and below the steel strip, the light source transmitter and the light source receiver correspond to each other and keep a gap with the steel strip.

The light source detector is an AW630 type light source detector, and the distance between the two light source detectors along the strip transverse direction is 700mm.

The beneficial effect of the utility model is that the strip width detected by the light source detector and the distance between the two light source detectors can be used to calculate the strip width, so as to realize the real-time monitoring of the strip width of the galvanizing line. online test. According to the real-time monitoring strip width data, the tension of the whole line can be adjusted according to the change of the strip width, and the rolling force of the skin pass mill can be adjusted to keep the strip width within the allowable tolerance range.

Description of drawings

Fig. 1 is a structural schematic diagram of an on-line detection device for strip width of a galvanizing line of the present invention.

Marked in the figure: tension roller 1, steering roller 2, steel strip 3, light source emitter 4, lateral distance 5 and light source receiver 6.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the utility model galvanizing line strip width on-line detection device includes a tension roll 1 and a turning roll 2 arranged on the galvanizing line, between the tensioning roll 1 and the turning roll 2 two strips of the strip 3 Light source detectors are oppositely arranged on the sides along the strip 3 in the transverse direction. The longitudinal direction of the strip 3 refers to the direction in which the strip flows along the galvanizing line, and the transverse direction of the strip 3 is perpendicular to the longitudinal direction of the strip. The strip steel on-line detection device is installed between the tension roller 1 and the steering roller 2 in the galvanizing line, where the strip steel 3 is stretched straight through the tension roller 1 and the steering roller 2, and the vibration of the strip steel 3 is minimal, which affects the detection of the light source Minimal, the light source detector is arranged on the both sides of strip steel 3 along the transverse relative position of strip steel 3, namely the light source detector can detect the edge of both sides of strip steel 3, and the light source detector on strip steel 3 both sides along The transverse direction of the steel strip 3 is on the same straight line, so that the width of the same position in the transverse direction of the steel strip 3 can be detected. The main function of the light source detector is to detect the range of changes in the two sides of the strip steel 3. The effective detection length of the general light source detector is less than the width of the strip steel 3. Two light source detectors are respectively arranged on both sides of the strip steel 3. It is used to detect the edge of the strip steel 3. The middle part of the strip steel 3 is fixed, but the width of the edge will change, and the distance between the center of the strip steel does not need to be detected. It only needs to detect the strip steel 3 detected by the two light source detectors. The width of the strip steel 3 can be obtained by adding the width of the broadside to the distance between the two light source detectors. The distance between the two light source detectors can be adjusted to meet the needs of the same detection width.

The light source detector is composed of a light source emitter 4 and a light source receiver 6 respectively arranged on and below the steel strip 3, and the light source emitter 4 and the light source receiver 6 are arranged oppositely and keep a gap with the steel strip. The light source transmitter 4 is used to send out the detection light source, and the light source receiver 6 is used to receive the detection light source. The light source transmitter 4 and the light source receiver 6 are arranged oppositely to ensure that the detection light source sent by the light source transmitter 4 can be received by the light source receiver 6. The transmitter 4 and the light source receiver 6 keep a gap with the steel strip to ensure the smooth operation of the steel strip 3 and the light source detector is not damaged by the steel strip 3 .

The light source detector 3 is an AW630 type light source detector, and the distance 5 between the two light source detectors along the strip 3 is 700 mm. The effective detection length of the AW630 light source detector is 450mm, the distance between the two light source detectors is set to 700mm, and the effective width that can be detected is 1600mm, which effectively exerts the detection ability of the light source detector and can adapt to all specifications of the galvanizing line The steel belt 3.
