With the rapid development of industrial automation in recent years, machine vision, as a smart brain endowed with "eyes" to machines, has been widely used in various fields of intelligent manufacturing. In the context of the rapid penetration of artificial intelligence into the Internet and emerging industries, traditional industries are also constantly promoting intelligent upgrading. The steel industry, which is the backbone of the manufacturing industry, is also gradually integrating machine vision into its digital technological transformation.
The main purpose of the application of machine vision in the steel industry is to cooperate with production, and help enterprises improve efficiency, so that factories can be lean and accurately manufactured. And at the process level, machine substitution and remote operation are implemented to make the production line unmanned and less manpowered, and obtain high efficiency.
There are many types of steel materials and various forms, such as profiles, plates, coils, bars, etc. Due to the complexity of the production process, the quality of steel products has a great impact on downstream applications, so the use of vision for quality inspection is of great significance to the steel industry.
In view of the situation that there are many types of production in a single production line, the testing equipment often needs to take into account different sizes, and the temperature of some hot steel is high, so it is also necessary to take into account the working distance requirements. SICK's 3D vision products offer a wide range of high-precision, fast, and powerful algorithms, and can also be flexibly customized according to customer requirements to improve inspection efficiency and quality.
Heavy-duty rail profile size measurement and 3D defect detection
Heavy-duty rail is a type of section steel and the main component of railway track, which is used to guide the wheels of the locomotive forward, withstand the huge pressure of the wheels, and provide a continuous, smooth and low-resistance rolling surface for the wheels.
The inspection items that usually involve vision are rail profile measurement, surface defect detection, section analysis, straightness detection, surface roughness detection, etc.
Vision solutions
Based on the requirements of multi-directional and flexible installation, the Ranger3-60 high-speed 3D camera from SICK was selected to collect images from multiple angles and calculate precise inspection results.
Plate profile measurement and 3D defect detection
Medium and heavy plate steel plate is one of the important products of the steel industry, mainly used in aerospace, bridge construction, automobile manufacturing and defense equipment and other fields.
In the rolling process, compared to cold-rolled sheets, medium and heavy plates need to be rolled at a higher temperature and in a harsher environment using the hot rolling process. Typical visual inspection items are dimensional deviations, cracks, depth defects, etc.
Vision solutions
Due to the temperature and heat dissipation requirements of the hot steel plate, it is often necessary to have a long working distance and cover the overall field of view of about 5 m, so multiple high-speed 3D cameras Ranger3-60 from SICK are used to shoot on the upper and lower sides, and the optical architecture is customized based on the advantages of high precision, high speed, high stability, and high flexibility.
H-rail profile size measurement and 3D defect detection
H-beam is a kind of steel that is arranged at right angles in all parts, which has the advantages of strong bending resistance and light structural weight.
Before forming the factory, the profile needs to be inspected for full size. Among them, the detection has the following difficulties: there are many types of products, complex shapes, and H-beam involves multi-angle splicing detection, which requires a large field of vision and fast detection speed.
Vision solutions
Ranger3-60 camera with M30 high-speed sensor from SICK, 2560 pixels in X direction, frame rate up to 46 KHz (ROI mode: 128 rows)
The Ranger3 camera can be flexibly combined with different lenses and lasers according to the profile size to complete a variety of product inspections
The Ranger3 camera equipped with this vision system achieves an inspection accuracy of 0.3 mm x 1 mm x 0.3 mm at a high speed of 4 m/s
The use of SICK 3D cameras can better solve the problems of high-speed inspection on the production line, flexible compatibility with a wide range of products, and replace manual labor for complete inspection of the production line.

Sick Sensors – What are the Common Types of Proximity Sensors?
Capacitance – As the name suggests, these sensors work by recording changes in capacitance, which is a function of charge and voltage between two surfaces with an air gap or other material known as the dielectric constant. When the object to be measured enters the sensor field, it has an impact on the medium.
