  1. 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

  2. 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.

  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.

  9. Zirconia Ceramic Foam Filters

    Zirconia Ceramic Foam Filters

    To meet the demanding requirements of steel foundries, SELEE Corporation recommends the Zirconia (PRZ) filter.

    Our PRZ filters are formulated of a magnesia-stabilized zirconia, the perfect composition for filtering steel grades from carbon to stainless.
    There are many benefits to the steel foundry including fewer reoxidation and sub-surface defects and a higher casting yield. They are highly thermal-shock resistant, a must for the steel foundry.
    They are available in many standard and custom sizes, shapes, and pore sizes.

  10. Ferro Titanium

    Ferro Titanium

    Titanium is highly reactive in steelmaking and combines readily, and forms stable compounds, with carbon, oxygen, nitrogen and sulfur. Because of it's reactivity, it may be used to fix these elements, reducing or eliminating their sometimes harmful effects.
