Product catalog summary

Introduction
The document discusses the application of optical temperature measurement in bar mills, emphasizing the importance of precise temperature control in the production process to meet high material property demands. Modern measuring methods, such as pyrometers, are essential for achieving these requirements.

Temperature Measurement with Pyrometers
Pyrometers are used to measure the temperature of billets and bars by detecting infrared radiation. This contactless method allows for quick temperature recording, which is crucial for monitoring and controlling the heating and rolling process.

Environmental and Material Interferences
Infrared measurement can be affected by environmental factors like dust and smoke. Two-colour pyrometers are preferred as they provide reliable measurements even with up to 90% interference. The CSD (Clean Surface Detection) function helps minimize the impact of scale and oxide on measurement accuracy.

Measuring Points and Equipment

After the Heating Furnace: The CellaTemp® PX 40 two-colour pyrometer measures billet temperatures with high optical resolution and features like through-the-lens sighting and a video camera for alignment.
Rolling Stand and Wire Mesh: The CellaTemp® PKL 63 pyrometer, with panoramic optics and a rectangular measuring field, ensures reliable temperature measurement of moving objects like swinging rods.
Mobile Temperature Measurement: The CellaPort PT 143 portable pyrometer is used for mobile control measurements, featuring automated temperature detection and easy alignment.

Mountings
Various mounting options are available, including dust stops, cooling jackets, and air purges, to ensure optimal pyrometer performance.

Sales and Service Centers
The document lists contact information for sales and service centers across several countries, including France, Italy, Austria, Russia, Spain, China, India, and Korea, as well as the headquarters in Germany.

Application note Bar mill Optical temperature measurement in the bar mill The increasing demands on the material properties of rolled goods become ever more demanding in terms of the production process and production parameters. For this purpose, very narrow tolerances of the rolling temperature are specified by the quality management. In order to be able to meet these high requirements, modern measuring methods and measuring systems adapted to the respective measuring points are absolutely necessary. Temperature-controlled rolling is the prerequisite for achieving the desired material properties...
