Temperature Monitoring in Primary Metals Processing

High Temp Heat Treating

Optimize product quality, improve furnace performance, and validate your process

The high temperature heat treatment industry remains at the core of our daily lives, as temperature uniformity and hardening are vital to the performance, durability, and reliability of the end-products used throughout the automotive, aerospace and electronics manufacturing industries. Getting the exact temperature of the product and its environment is critical to the quality of the final product.

The Datapaq Furnace Tracker Profiling System is comprised of a collection of data loggers, thermal barriers, and application-specific software designed to help you optimize product quality, improve furnace performance, and validate your process for suppliers.

Meanwhile, the Endurance Series is a collection if high-temperature infrared pyrometers that aid in improving product quality and uniformity, reducing reject rates, maximizing throughput, and minimizing energy costs through continuous temperature monitoring and “set it and forget it” reliability.

Application Need 

Heat treatment facilities often support multiple industries on any given day. As a result, there are many different, albeit exacting, heat treatment specifications that require engineers to continuously adjust the furnace settings to match the temperature profile needed for each batch.

Because temperature profiles are unique to each batch as well as the overall quality and reliability of the final product, it is vital that engineers set their furnace to the exact temperature. If these temperatures are incorrect, facilities run the risk of defective products, decreased furnace performance, unnecessary downtime, and more.

In some situations, temperature may be measured by trailing thermocouples, but this is only feasible in limited cases like monitoring semi-continuous furnaces. By implementing a robust profiling system, however, facilities can profile multiples processes from within the furnace with a range of data loggers and thermal barriers.

In other circumstances, such as where heat treatment facilities want to monitor product temperatures in process, spot pyrometers can be used. Infrared pyrometers are more feasible in continuous casting, for example, as they allow facilities to measure targets that would otherwise be inaccessible due to space constraints or harsh conditions. Spot pyrometers also allow for direct traceability of product quality, allowing facilities to see the full scope of their process.

With accurate temperature measurement tools in place, heat treatment facilities can ensure each client’s product specifications (with traceability) while improving overall furnace performance, throughput, and more.
