F R S 16 0 0 FR S 18 0 0 Furnace Rheometer Systems Rheological measurements at high temperatures FRS – Furnace Rheometer Systems Materials of regular use in everyday life, such as glasses, ceramics, and metals are processed or refined as melts at temperatures above 1000 °C. By determining the melt viscosity of these materials with the FRS, a consistent high quality of the final product and an optimization of the energy-intensive production process can be ensured. Furthermore, this system opens up new ways in R&D of materials with a high melting point. The Furnace Rheometer Systems each combine a rheometer and a lab furnace for viscosity measurements of melts at furnace temperatures up to 1800 °C (1700 °C sample temperature). The setup The Furnace Rheometer Systems consist of a lab furnace (Carbolite) and the DSR 502 rheometer head, which features the established EC motor and air-bearing technology of the MCR rheometer series. The system is air- and water-cooled to ensure a constant sample temperature. The combination of pneumatic pre-positioning and the stepper-motor-driven fine positioning ensures a controlled and accurate immersion of the measuring system into the sample in the molten state. The normal force sensor in the rheometer head allows for precise detection of the melting point during the measurement in rotation. FRS provides solutions for the following industriesYour benefits Metal industry: metals, slags, and coal ash Glass industry Mining industry Ceramic industry Volcanology (research) REFERENCE POSITION Highest safety and easy sample loading 1 Measurements of low viscosities with the unique air-bearing motor 2 Pneumatic lift down to preheating position Pneumatic lift up to preheating position Electric lift down to measuring position Normal force control for detecting the melting pointMeasurements under inert gas atmosphereCompliance with the international standards ASTM C1276, ASTM C965, and ISO 7884-2 3 4 5 The EC motor technology – your key to accuracy 25 years of experience in one motor – you only get this with rheometers from Anton Paar. The air-bearing-supported synchronous EC motor deploys a frictionless synchronous movement of the rotor inside which enables the most sensitive and therefore most precise movements in rotational and oscillatory mode – for accurate results across a wide shear rate range. In this way even low viscous samples can be measured with an unprecedented precision.
