Thermocouples

SIDERMES produces a broad range of platinum-platinum/rhodium (Pt-Pt/Rh) immersion thermocouples used to measure the full temperature range of molten metal for all applications. The SUPERTEMP immersion thermocouples are produced pursuant to the IPTS 68 and ITS 90 standards.
The SIDERMES immersion thermocouples are produced in accordance with quality standard ISO 9001:2008. They are compatible and interchangeable with the most widespread connection and instrument systems on the market.

Oxygen measurement

Our TOX (Temperature & Oxygen) probes measure the temperature and ppm of free oxygen in liquid metal, in less than 10 seconds.  The two mV signals generated by the TOX probes are transmitted to the instrument, processed and visualized so as to display the values of temperature and ppm of free oxygen; furthermore, the value of %C or %Al dissolved in the bath of liquid steel is automatically calculated.

Carbon measurement

Economical and easy to use, the SUPERCARB S thermal analysis cups are designed to achieve fast and reliable values of %C in liquid steel.
Alternatively, SIDERMES offers two of types of immersion probes: INCARB(carbon only) and TECARB (carbon and bath temperature). Using either sensor further decreases the tap-to-tap time, thereby providing increased productivity. Both the cups and the immersion probes use high precision thermocouples and instrumentation to analyze the cooling curve and find the relative liquidus temperature corresponding to the %C in the melt.

Samplers

The SUPERSAMP samplers are designed for fast, safe, and economical molten metal sampling. Various versions are available, so that the most specific and easiest sampling procedure and metal analysis can be achieved for every application. They provide the user with a representative sample of the liquid bath which, after a rapid surface cleaning, is ready for the chemical analysis. The lab preparation time is minimized by the special design of these samplers.

Combined probes

These probes are a combination of two or more "STANDARD" probes.
The available probes are:

• CET, temperature + sample
• CET-OX, temperature + sample and free oxygen
• TECARB, temperature + %C 
• TOX, temperature + ppm of oxygen

Although recommended for automatic measurement systems, they may also be used in manual applications.

SUBLANCES

The SUBLANCE probes, used with automatic measurement systems, are designed to reduce the tap-to-tap time in the converter, avoiding direct and indirect costs due to the rotational movement of the converter (tilting). The available SUBLANCE sensors meet all measurement and sampling needs in all possible combinations. Furthermore, they can determine the level of the bath in the converter.
The following versions are available:

• Te, temperature
• TOS, temperature + sample + ppm oxygen
• TCS, temperature + %C + sample
• TO, temperature + ppm oxygen
• BL, bath level

The SUBLANCE sensors are customized according to the specific needs of each customer.

Hydrogen measurement

The ACCU-H2 probes allow on-line Hydrogen measurements (ppm) of dissolved Hydrogen in molten steel, within an analysis period usually below 60 seconds. The probes are composed of various parts designed in order to grant an accurate separation of sampled gas in between the carrying gas (usually, Nitrogen) and the Hydrogen. This technology and probe design grants the possibility to perform safe and accurate measures also in difficult conditions and special steel grades.
