Steel industry : Temperature measurement and measurement technology for steel production
Steel is almost entirely recyclable, making it one of the most important materials on the planet. Many environmentally relevant technologies such as wind farms, turbines or lighter car chassis are based on innovations in the steel industry.
RÖSSEL-Messtechnik supports the steel industry along the entire path of technological advancement as an experience partner.
Our thermocouples and resistance thermometers are used for process control and monitoring in all parts of the industry. We offer calibrated sensors compliant with CQI9 or AMS 2750 and sensors with ATEX approval from one single provider. We also produce special thermowell combinations for use in casting machines for both molten aluminum or for molten steel.
Whether it’s processing sheet metal for space travel or for everyday use: RÖSSEL-Messtechnik not only supplies the suitable thermocouples and resistance thermometers for steel processing, we also conduct long-term research and development projects, for example in partnership with the Montanuniversität in Leoben, Austria.

Liquid steel is produced from a mixture of raw materials in a Bessemer bulb at 1,200°C as part of a technically demanding process. Temperature measurement allows the process to be controlled and protects the melting apparatus. RÖSSEL-Messtechnik provides straight thermocouples for gas temperature measurement and sheathed thermocouples for surface temperature measurement.
Adding oxygen to liquefied pig iron in a large refractory vessel (converter) oxidizes out unwanted carbon. This can only be executed and tracked with accurate temperature measurement. Our robust thermocouples are specially designed to be used in this explosive atmosphere.
In a preheating furnace, slabs from the converter are heated to a temperature of 100°C. Thermocouples are used at this stage for process control. The red-hot slabs are then rolled into sheets under high pressure in a high-performance cylinder rod assembly. Resistance thermometers stop the bearings from being overloaded.
Thermocouples are used for process control during annealing in bell-type annealing systems for coils. A continuous sheet is then pickled and rolled several times until the required sheet thickness is reached. The resistance thermometers used warn against overloading of the bearings in the cylinder rod assembly. During galvanizing, liquid zinc is applied to the sheet, which is at the correct temperature thanks to the thermocouples. Our robust thermocouples are specially designed to be used in this explosive atmosphere.
Convincing steelworkers with time-saving ideas
When it comes to steel tube production, ever-higher quality requirements are making increasingly time-consuming comparative measurements on furnaces mandatory. One of our customers with seven production sites and 4,400 employees around the globe found this had a major impact on costs and safety. Before we stepped in, the process had to be brought to a full stop to check the measurement technology, which lost valuable production time. RÖSSEL-Messtechnik designed an innovative connection housing that allows sensors to be inspected during ongoing operations thanks to its high functionality, saving time and significantly improving occupational safety as a result. The design modification has been successfully launched in seven countries to date and is also suitable for use in other industries such as furnace construction.
