Temperature is one of the most crucial process parameters in metal casting. Monitoring and controlling molten metal temperature is essential to yielding foundry products which feature desired physical properties such as tensile strength. CellaCast, a newly developed non-contact temperature measurement system, captures the precise in-stream temperature of each pour, providing full traceability for each cast product and documented evidence of conformity to tolerance requirements. The reduced amount of process scrap and a decrease in the number of thermocouples required lead to a reduction in operating costs. Source

Two-colour pyrometers have become an integral part of today's infrared thermometer applications. The following article explains the physical principles, advantages, functional and analytical possibilities and also the limits of two-colour pyrometry. Practical applications demonstrate typical areas of use. Source

Fauci L.,Keller HCW GmbH
CFI Ceramic Forum International

Keller HCW GmbH undertook a modernization project at Gruppo Fauci's Sciacca production site in Sicily, Italy. The modernization project helped the site to improve its production flexibility significantly. The project was undertaken when Gruppo Fauci decided to modernize the Sciacca brick factory in an effort to increase the quality of 50 different products and minimize the times for size changeovers. The first modernization effort was realized in 1997 and included the modification of the wet and dry sides, the setting machine, and the dryer. Two robots were installed on the wet side to receive the products coming from the cutter in several rows. These products were gripped on their cut faces and set down on pre-prepared large-sized pellets after being grouped. Source

Pyrometers detect thermal radiation in a defined measurement area on the surface of a measurement object and calculate the temperature from these radiation values. Size and shape of the measurement area are determined by the pyrometer's lenses, its optical assembly and the sensor system. Due to their lens geometry, aperture system and sensor element, the devices available on the market usually come with a round field of view. Based on a novel optical design and high-quality lenses, some manufacturers have recently started to offer devices with a rectangular measurement area. The following article explains structure, mode of operation, advantages and applications of pyrometers with a rectangular measurement area. Source
