What are the measures for intelligent measuring instruments to support compliance and efficiency improvement in steel rolling industry?

Intelligent measuring instruments have brought many changes to steel rolling production. All real-time values are clear at a glance, all necessary charts can be drawn, unqualified products can be found in time, historical data can be stored and viewed, periodic defects can be easily found, and trial and error times of initial rolling can be reduced when specifications are changed. In a word, the use of intelligent measuring instruments makes steel rolling production more intelligent.

It is often used as an intelligent measuring instrument for geometric dimensions of steel rolling production line.

Laser caliper

Calipers are used to detect the outer diameter and ellipticity of various wires, bars and pipes, and can obtain cross-sectional drawings, understand the cross-sectional changes in real time, and judge simple surface defects such as lugs and staggered rollers. The commonly used eight-axis calipers can completely detect the cross-sectional dimensions, and can also detect the internal diameter, transverse ribs, longitudinal ribs and other dimensions of steel bars. Of course, calipers of other shafts can also be customized according to other requirements, and there are also large-diameter calipers with adjustable spacing.

Straightness measuring instrument

It is divided into on-line straightness measuring instrument and off-line straightness measuring instrument, which can detect information such as outer diameter, ovality, straightness size per meter, overall straightness size, oblique head and oblique tail. It is mainly used to detect the straightness and size of round wire rod, bar and pipe in real time, and the detection data can be transmitted to the required system.

Width measuring device

There are many kinds of width gauges, which are mainly used to detect the width and size of plate products. The width range can be adjusted. At present, the on-line width gauge based on photoelectric measurement principle is commonly used, which has high precision, wide range and high cost performance.

Thickness gauge

Laser thickness gauge is commonly used, which can be divided into contact thickness gauge and non-contact thickness gauge, and can be customized into multi-point thickness gauge or scanning thickness gauge according to the detection needs to meet the thickness detection needs of various positions.

Length measuring instrument

On-line length measuring instrument based on machine vision method, according to different plate lengths, different numbers of industrial cameras are installed to complete the detection. Because it is shot with an industrial camera, you can see all kinds of images of steel, whether it is bar, pipe or plate, on the measurement and control software system.

Contour recorder

The profilometer mainly measures various information such as contour, surface defects and geometric dimensions. It has a large number of detection data and wide applications. It is no longer limited to the detection of regular circular products, and can be used to measure various types of outstanding talents such as squares, T-shaped, H-shaped and rail beams.

Data acquisition management software system

The main function of the data acquisition management software system is to collect data of different equipment in the rolling mill, and conduct unified management and analysis. Various interfaces are currently supported. As long as there is a corresponding interface and it needs to be collected, it can be collected, summarized and analyzed, and the collected data can be transmitted to other devices or systems without worrying about interface mismatch.
