  1. Carbon Control

    Carbon Control

     Based on the Thermal Analysis of a solidifying metal sample, Heraeus Electro-Nite's instant carbon control sensors are available as a crucible version or as an immersion sensor. During primary steel melting and steel foundry casting, an instant carbon measurement prior to tap can avoid time delays and off-specification chemistry, especially where medium carbon tap levels are common.

  2. Hydris® & Nitris®

    Hydris® & Nitris®

    Today, Heraeus Electro-Nite's patented hydrogen sensing system is the world's industrial standard for hydrogen measurement and control in liquid steel. Designed to precisely measure the total range of possible prevailing hydrogen on-line in less than a minute, the system has replaced traditionally time consuming, and frequently erratic sampling methods.

    Brand name: Hydris®

    Using a similar device and operating system as a Hydris sensor, nitrogen can be measured on-line in secondary and tundish metallurgy. The system's accuracy easily matches the combustion analytical method while providing time savings as compared to a solid sample retrieval and analysis method.

    Brand name: Nitris®

  3. Oxygen Control

    Oxygen Control

    Monitoring oxygen activity throughout the steel making process is essential for production control and final as-cast quality. In less than 10 seconds, our expendable oxygen sensors measure the melt's oxygen activity a(O) over a wide concentration range in areas from hot metal desulphurization, furnace tapping, through ladle refining and continuous casting. Correlations to S and Si in Hot Metal, carbon and aluminium in primary and secondary steelmaking are implemented in the formulas of our instruments.

  4. Thermal Analysis - Cast Iron

    Thermal Analysis - Cast Iron

    Tracing and analyzing the temperature of a cooling and solidifying iron sample is named Thermal Analysis. The plateaus of liquidus and solidus temperatures of the cooling iron sample in a cup allow the calculation of carbon equivalent, carbon and silicon. Relevant formulas in our instruments may be used to calculate physical properties of the iron casting.

    Our range of QuiK-Cup cups (QuiK stands for Quartz insulated type K thermocouple) are designed for various types of cast iron, unalloyed, alloyed, solidifying grey or white and taken from Cupola through runner, furnace or tundish.

    Sensor: QuiK-Cup
