The intelligent control system of steel rolling, the implementation of intelligent steel rolling, the improvement of product qualification rate, and the meeting of the needs of the bar production line for product accuracy, production output, and remote centralized control are the goals that the steel mill has been committed to achieving at present.
1. Surface detector:The surface defects of rolled parts are the factors that affect the quality of steel, and the profilometer can be used to identify defects, enter them into the system, and reject or retain them according to the process requirements to improve the quality of rolled parts.
2. Headless rolling technology:Continuous casting and rolling headless rolling technology is more suitable for new production lines. Headless rolling can increase production capacity, so that enterprises can obtain direct economic benefits, which is conducive to energy conservation and emission reduction.
3. Intelligent rolling and cooling control equipmentWhen it comes to the production of special steel grades such as bearing steel and spring steel, which require controlled rolling and cooling, the use of various measuring instruments and control systems contributes to the improvement of quality.
4. **Caliper:The use of first-class detection technology can improve the detection speed, solve the problems of missed detection, slow detection speed, and potential safety hazards in manual sampling, and also benefit from improving product accuracy control.
5. Increase automation equipment on the inspection benchAutomatic counting device, bar weighing and baler system and OEM, welding robot, etc.
6. Multi-layer network communicationThrough the function subdivision of the basic automation system and the substantial improvement of control accuracy, supplemented by the production big data system and feedforward adjustment model.
7. Unmanned overhead crane and intelligent warehouse management technologyAccording to the requirements of the existing intelligent warehouse management, the fixed material frame stacking yard is managed by partition and positioning, so that the whole process of bar can be tracked.
Lanpeng Measurement & Control produces a variety of geometric size measurement equipment, and currently can customize three categories of intelligent help: profilometer, caliper and data acquisition and analysis system.
The profilometer is specially used to detect surface defect information, and can detect scratches, pits, wrong rolls, folding, peeling, fish scale peeling, scratches, roll impressions, unilateral flanges (ears), bilateral flanges (ears), unqualified roundness, longitudinal ribs too high, longitudinal ribs too low, no transverse ribs, transverse rib deformation and other surface defects. In addition, basic geometrical information such as outer diameter, ovality, etc. can also be checked. It can also locate the surface defects of the rolled steel, and the size, position, number and other parameters of the defects detected by the rolled steel in the measured time can be marked accordingly on the contour graph.
* The caliper uses an eight-axis photoelectric probe for non-contact detection, which can detect the outer diameter size in eight directions of the same section, and the torsion in the movement of the rolled steel enables it to carry out all-round detection, and the outer diameter, ovality, average diameter and other information can be obtained through the first detection, and the analysis charts such as cross-sectional diagrams, waves, defect diagrams, and trend charts can be obtained, and historical data storage including chart information can be obtained, and the data transmission function of the control system and MES system can be transmitted to the control system. Better guide the process adjustment, so as to improve product quality and yield.
The data acquisition and analysis system has a variety of interfaces, which can transmit data with various equipment and systems, collect the required information, unify the summary, analysis, monitoring, storage, etc., guide production, realize the front and back penetration, complete the accumulation, transmission, analysis, processing, and remote centralized control of big data, and further improve production efficiency.
Different equipment has different functions, but when various intelligent equipment and various systems are combined, the role is huge, not a simple superposition, and the overall improvement, for the automatic production and rolling to bring performance, quality, efficiency, benefits and other all-round improvement.
