The sub-lance probe boasts several advanced features that make it indispensable in steelmaking. Firstly, it supports multiple measurement functions, including temperature, carbon content, and oxygen content, all in a single operation. This multifunctionality eliminates the need for separate tools, streamlining the process. Secondly, it offers high accuracy in measurements, with carbon content deviations as low as ±0.02% and temperature measurement rates exceeding 98%. The probe also features a rapid response time, with temperature and carbon measurements completed in ≤8 seconds, ensuring real-time data availability. Additionally, it is designed to collect steel samples efficiently, with sampling rates above 95%. The probe's compatibility with different steel sample shapes, such as round and double-thickness samples, further enhances its versatility. Its robust design ensures reliable performance even in the harsh environment of molten steel.

Details & Parts

Principle

The sub-lance probe operates based on advanced sensor technology and precise data acquisition systems. For temperature measurement, it utilizes thermocouples embedded within the probe, which detect the heat of the molten steel and convert it into electrical signals. These signals are then processed to provide accurate temperature readings. For carbon content measurement, the probe employs electrochemical sensors that react with carbon in the molten steel, generating voltage signals proportional to the carbon concentration. Oxygen content is measured using similar electrochemical principles, where oxygen sensors detect the presence of oxygen and produce corresponding signals. The collected data is transmitted to the control system in real time, enabling operators to make informed decisions. The probe's sampling mechanism involves a specialized design that ensures consistent and contamination-free steel sample collection, which is critical for accurate offline analysis.

Advantage

The sub-lance probe offers numerous advantages that significantly enhance steelmaking operations. Firstly, its ability to provide real-time measurements of temperature, carbon, and oxygen content allows for precise control over the smelting process, reducing the likelihood of errors and improving product quality. Secondly, its high accuracy and rapid response time ensure that operators can make timely adjustments, optimizing production efficiency. The probe's multifunctionality eliminates the need for multiple tools, reducing operational complexity and costs. Additionally, its robust design ensures durability and reliability in the demanding environment of molten steel. By improving the double hit rate of carbon temperature endpoints, the probe helps achieve consistent steel quality, reducing waste and increasing yield. Finally, its efficient sampling mechanism ensures high-quality steel samples for offline analysis, further enhancing process control and product consistency.
