Introduction
The document discusses the application of optical temperature measurement in tube rolling mills, emphasizing the importance of precise temperature control to meet the increasing demands on material properties. Modern measuring methods, such as pyrometers, are essential for achieving desired material properties and maximizing efficiency.

Temperature Measurement Techniques
Pyrometers are used for measuring temperature during various rolling processes. They operate by measuring infrared radiation and calculating temperature based on Planck’s law. This method allows for contactless measurement from a safe distance, providing rapid temperature readings for process monitoring and control.

Challenges in Infrared Measurement
Environmental factors like dust, steam, and smoke can affect the reliability of optical measurements. Two-colour pyrometers are preferred as they provide reliable readings even with up to 90% obstruction. Surface scaling and oxidation also impact measurement accuracy by altering emissivity. The CSD (Clean Surface Detection) function helps minimize these interferences by focusing on scale and oxide-free surfaces.

Measuring Systems and Equipment
The document details various measuring systems, including the PX 40 and PX 60 models, each with specific temperature ranges and features like laser pilot lights and two-colour pyrometer technology. These systems are designed for different stages of the rolling process, such as post-heating furnace and pre-reheating furnace measurements.

Installation and Components
Mounting components for the pyrometers include dust stops, clamping collars, cooling jackets, and air purges, ensuring optimal performance and protection of the equipment.
