Product Introduction
A sublance probe is a sophisticated sensor system used in the steelmaking industry, particularly in converter processes, to perform real-time measurements and sampling without interrupting the refining operation. These probes are designed to simultaneously measure critical parameters such as molten steel temperature, carbon and oxygen content, and liquid level, while also collecting representative steel samples for laboratory analysis. By integrating advanced sensing technologies, sublance probes enable dynamic process control, allowing steelmakers to optimize blowing strategies, reduce energy consumption, and enhance product consistency. Their high accuracy (temperature ±0.5°C, oxygen potential ±5mV) and reliability (success rates exceeding 98% for key measurements) make them indispensable for modern high-efficiency steel production .
Constructed with specialized materials like zirconium diboride composites and high-purity alumina ceramics, sublance probes withstand extreme temperatures up to 2300°C, ensuring durability in harsh molten environments . Key components include precision thermocouples for temperature detection and solid-state oxygen cells for determining oxygen activity, which work in tandem with thermal analysis algorithms to calculate carbon content. For example, TSC probes use the solidification temperature of steel to infer carbon levels, while TSO models incorporate oxygen potential measurements to derive carbon concentrations through carbon-oxygen equilibrium equations . These probes also feature ergonomic sampling chambers that capture steel samples with precise dimensions for spectral and gas analysis. By eliminating the need for manual sampling and enabling rapid data feedback, sublance systems streamline operations, shorten tap-to-tap times, and support sustainable steelmaking practices .
