Product catalog summary

Introduction
The document discusses the importance of precise temperature measurement in continuous casting processes to meet stringent material property requirements. It highlights the necessity of modern, non-contact measuring systems like pyrometers for efficient temperature control.

Optical Temperature Measurement
Pyrometers are used for measuring the temperature of molten metal and cooling slabs or billets. They operate based on infrared radiation and Planck’s law, providing quick and non-destructive temperature readings.

Measuring Point: Pouring Stream
The CellaCast system offers non-contact temperature measurement of the pouring stream, overcoming limitations of traditional immersion methods. It features a Clean Surface Detection (CSD) function to ensure accurate readings by focusing on oxide-free metal surfaces. The system is maintenance-free and provides reliable data even in harsh conditions.

Measuring Point: Slab/Billet
Two-colour pyrometers are preferred for measuring slab or billet temperatures due to their reliability in dusty or smoky environments. The CSD function helps filter out interference from scale and oxide, ensuring accurate temperature readings.

Measuring Point: After Separation
For temperatures below 650°C, the CellaTemp® PA/PX 20 pyrometer is recommended. The document lists various pyrometer models, their specifications, and sighting aids.

Technical Specifications
The document provides detailed specifications for different pyrometer models, including measuring ranges, spectral ranges, and mounting combinations.

Sales and Service Information
Contact information for sales and service centers in various countries is provided, along with details of the headquarters in Germany.

Application note Continuous casting The special feature of optical temperature measurement for liquid metal is that oxides and slag form very quickly on the surface of metals. For a correct measurement, it is imperative that the pyrometer only evaluates the radiation of the bare metal surface. The CellaCast measuring system has a special CSD function (Clean Surface Detection) for this purpose. This filters out the temperature of the pouring melt at the slag-free and oxide-free areas of the metal. Thanks to the two-colour measuring method, the pyrometer delivers reliable measured values even under...

ature at the scale- and oxide-free points of the passing slab from a distance of several metres in combination with the CSD function. For optical alignment, the devices have a through-the-lens sighting, a laser pilot light or a video camera. With the camera function, the measuring environment and measuring point can be checked at any time on the monitor in the control room. The measuring field marking, the measured temperature and the measuring point designation are displayed in the monitor image via the video signal. The CellaTemp® PA has a conventional analog output for connection to the plant...
