Embodiment 1

[0037] Embodiment 1: An online detection system for strip steel wave shape includes a detection unit, which is used for real-time detection of strip steel wave shape data.

[0038] see figure 1 , Figure 4 , Figure 5 and Image 6 , the detection unit has a frame 1, the frame 1 has a sensor installation crossbeam 11, and the bottom of the sensor installation crossbeam 11 is provided with several linear laser sensors 2 for measuring the wave shape of the strip steel, and the arrangement of the sensors is an array. The linear laser sensor 2 is connected with a multi-channel synchronous data acquisition controller 3 . The multi-channel synchronous data acquisition controller 3 is installed at the sensor installation beam 11 . The detection unit also has a strip position information sensor for measuring strip length information.

[0039] The installation position of the strip position sensor can be arranged according to the needs, for example, it is installed at the back idle...

Embodiment 2

[0051] Embodiment 2: a kind of strip steel wave form on-line detection method, after the data processing unit receives the start detection signal that rolling mill upper computer sends, record the coil number of strip steel, receive the strip steel wave form detected in the strip steel detection unit simultaneously Data, the horizontal wave shape value of the strip detected by each sensor in the linear laser sensor in the strip detection unit is generated into a histogram and displayed on the screen, and the longitudinal detection data is generated into a curve and displayed on the screen. According to the collected strip Steel wave shape data, the maximum wave height value of the measured steel coil and the corresponding position are displayed on the screen for users to preliminarily judge the wave shape information. graphic reference figure 2 , in this figure, the top is a histogram, the abscissa in the figure represents the width of the strip, the ordinate represents the w...

Abstract

The invention discloses a strip-steel wave shape online detection system. The strip-steel wave shape online detection system comprises a detection unit and a data processing unit, wherein the detection unit is used for detecting strip-steel wave shape data in real time, and the data processing unit is used for obtaining detection data and obtaining strip-steel coil number from an upper computer ofa rolling mill. Target data are generated according to the obtained steel coil number and the detection data, wherein the target data comprise a strip-steel transverse wave shape bar graph, a strip-steel longitudinal wave shape curve graph, the detected steel coil maximum wave height and a detected steel coil maximum wave height corresponding position; and then the target data are displayed. Theinvention further discloses a strip-steel wave shape online detection method. According to the strip-steel wave shape online detection system and method, wave-shape relevant information of each coil of steel strips can be recorded in real time, and an automatic detection report generation function is achieved according to the detected data. The strip-steel wave shape online detection system can beused for detecting the strip steel with the wave height lower than 500 mm, the detection frequency reaches 10 kHz, and the wave height precision is smaller than 0.1 mm; and a communication function with the upper computer of a rolling mill unit is achieved, and an offline query function on the detection data can be achieved.

Description

technical field [0001] The invention relates to the technical field of strip steel cold rolling, in particular to a system and method for on-line detection of strip steel wave shape. Background technique [0002] In the process of strip steel production, according to the needs of each production link, it is necessary to timely and accurately grasp the information of the strip steel, among which the wave shape index of the steel strip is a key indicator, and the level of the wave shape of the steel strip is related to the quality of the product. Timely and effective testing of the height of the side waves and middle waves has a certain guiding effect on the judgment of the quality of the produced products, the influence of the raw material wave shape on the product, and cost control; in addition, the comparison of the relevant data recorded through the wave shape detection , can grasp the degree of influence of the wave-shaped index on the client, and can effectively guide pr...
