In the metallurgical industry, accurate measurement of molten steel is a key link to ensure production safety and improve product quality. However, the measurement of molten steel in high temperature and harsh environment faces many challenges, such as high temperature corrosion, electromagnetic interference, dust coverage, etc. In order to ensure the accurate measurement of molten steel testing equipment, the industry has adopted a series of advanced technologies and strategies.
Application of laser ranging technology
Laser ranging technology has shown significant advantages in high temperature molten steel measurement with its non-contact measurement method. The laser molten steel level meter calculates the molten steel level based on the round-trip time difference or phase difference of the light signal by emitting a laser beam to the surface of the molten steel and receiving the reflected laser signal. This technology avoids the problems of high temperature corrosion and equipment damage that may be caused by traditional contact measurement, and ensures the accuracy and safety of measurement.
Selection of high temperature resistant materials
In response to the corrosion and wear problems in high temperature environments, the key components of molten steel testing equipment are made of special materials that are resistant to high temperature and corrosion. For example, laser transmitters and receivers usually use high-stability semiconductor materials that can maintain stable performance under extreme high temperatures. In addition, the protective shell and seals of the equipment are also made of high-temperature resistant and wear-resistant materials to ensure the long-term stable operation of the equipment at high temperatures.
Shielding and filtering of electromagnetic interference
There is often a complex electromagnetic environment at the metallurgical industry site, which interferes with the molten steel measuring equipment. In order to ensure accurate measurement, advanced electromagnetic shielding technology and filtering technology are used inside the equipment. By optimizing circuit design, adding shielding layers, using filtering elements and other measures, the impact of electromagnetic interference on the measurement results is effectively reduced.
Dust and stray light processing
In high-temperature industrial sites, dust and stray light are important factors affecting measurement accuracy. In order to solve this problem, molten steel testing equipment usually adopts dust-proof design and optical filtering technology. Dust-proof design effectively blocks dust from entering the equipment by installing protective covers and using sealing structures. Optical filtering technology uses high-performance optical filters to filter out stray light and interference light to ensure accurate reception and processing of laser signals.
Real-time monitoring and fault warning
In order to ensure the accurate measurement of molten steel testing equipment, real-time monitoring and fault warning technologies are also used. Through sensors and monitoring systems, the equipment's operating data and environmental parameters, such as temperature, humidity, pressure, etc., are collected in real time. When the data is abnormal or exceeds the set range, the system will automatically issue a warning signal to remind the operator to take timely measures to ensure the normal operation of the equipment and the accuracy of the measurement.
In summary, by adopting strategies such as laser ranging technology, high temperature resistant materials, electromagnetic interference shielding and filtering, dust and stray light processing, and real-time monitoring and fault warning, molten steel testing equipment can achieve accurate measurement in high temperature and harsh environments, providing strong guarantees for the safe production and product quality improvement of the metallurgical industry.
