The laser rangefinder for heating furnaces is mainly used to detect the position, size, and workpiece status of steel billets in the heating furnace under high temperature environment. It is widely used in automation control and quality control in industrial production. It is a non-contact measuring equipment designed for industrial furnace environments with high temperature, high dust, and strong interference. Its core is used for accurate detection of parameters such as material position, steel billet size, and material level height in the furnace. It is widely used in metallurgy, casting, building materials and other industries, and is a key instrument to ensure the safe and stable operation of heating furnaces.
core functionality
Steel billet position detection: Real time monitoring of the accurate position of steel billets at the inlet, outlet, and inside the heating furnace to ensure automated control of the production process.
Dimensional measurement: Measuring the length, width, thickness and other dimensional parameters of continuous casting billets through laser ranging technology, supporting processes such as cutting to length.
High temperature environment adaptation: Stable operation in high temperature environments (such as above 40 ℃), suitable for special needs in industrial scenarios such as heating furnaces.
Data output: Provides switch signals and position data, supports PLC system linkage, and optimizes production efficiency.
Flexible Function Expansion: Supports modifying parameters and viewing work status through a computer or handheld device. Some models can customize measurement ranges and output modes to adapt to different types of heating furnaces (such as ore thermal electric furnaces and continuous casting heating furnaces).
Precautions for use
During installation, it is necessary to stay away from the direct heat radiation area of the furnace mouth to ensure the normal operation of the water cooling/air cooling system and avoid optical lens coking or damage due to high temperature;
Regularly clean the dust and oil stains on the surface of the lens, which can be continuously protected by air blowing function to prevent affecting laser transmission;
Avoid direct laser exposure to human eyes (especially 3R level lasers), and on-site operators should wear protective goggles;
Ensure the correct polarity of the power supply (10-30VDC) during wiring, stay away from strong electromagnetic interference sources (such as motors and frequency converters), and ensure signal stability;
Adjust measurement parameters based on the reflectivity of the target being measured (such as optimizing laser power or range for dark or oxidized surfaces) to avoid measurement errors caused by weak reflection signals.
