introduction
The on-line bar gauge is an advanced wire and bar measuring tool. It adopts today's advanced micro-processing technology and uses eight sets of probes as the measuring line in rolling. The bar tool can usually be used for the same section. A comprehensive range of finished steel products can be obtained with extremely high measurement accuracy. Bar gauges can detect round steel or rebar with an accuracy of ±0.02mm, which can meet the production requirements of most domestic bar production lines.
1, equipment composition
The equipment consists of a power supply system, a measurement system, a control system, an output system, and an auxiliary system. The core part is the measurement system and the control system. The bar gauge has four wheels and is mounted on a guide rail. In the appropriate measurement position, the system is equipped with eight photoelectric probes. When the steel passes through the eight probes, the finished product can be measured. The measuring head is equipped with a high-resolution optical system.
To ensure accuracy, bar gauges are equipped with auxiliary facilities such as high-pressure blower and positive pressure diverting cooling dust-proof device and various information detection and alarm systems. High-pressure blowers are used for continuous purge detection of dust retained in optical systems, and are tested. Oxidized steel sheet of rolling material, etc., to ensure that the detection of light is sufficient and the measured object is clean; Positive pressure shunt cooling and dustproof device is used for cooling and cooling of electrical components and other important parts to ensure safe and stable operation of equipment.
In addition, this set of equipment is also equipped with an IPC system for statistical data analysis, which can analyze the products in the rolling process and has guiding significance for the producers' further production operations.
2, practical application
The bar gauge is installed on the rolling production line for on-line inspection. The core control system is in another closed operation room on the site. The output display system is located in the main control room of the rolling line and near the site of the finishing mill. The main control room operator completes the input control test information including the maximum value of the finished material, the minimum value, the ellipticity, and eight sets of test data.
For round steel, it mainly displays measured values such as eight-direction measured value, maximum value, minimum value, ellipticity, etc.; for the rebar, it is possible to monitor the transverse rib, longitudinal rib and inner diameter, cross section area, four values. When the test result exceeds the set value. When an alarm is issued, it prompts adjustments to avoid waste.
The most significant application of the on-line bar gauge is in the production of round bars. The dimensional accuracy of the round bar can reach ±0.02mm as mentioned in the design. For the production of rebar, the accuracy is ±0.08mm. .
Rod gauges are mainly divided into stop measurement interface, main interface, wave diagram interface, defect diagram interface, exit interface, and record file interface, system parameter interface, product parameter interface, auxiliary function interface, shutdown alarm interface, and help interface. .
Conclusion
The bar gauge can display all the information required for the measurement in detail. At the same time, some basic defects such as wrong rollers and ears can be detected. The bar gauge is used for high-precision on-line testing equipment. Quality and speed up production have brought great convenience.
