Temperature Monitoring in Primary Metals Processing

High Precision Heat Treatment in Vacuum Carburizing

Measure product and furnace temperatures for low-pressure carburizing applications at every stage with through process temperature monitoring.

Vacuum carburizing is an alternative that is growing in popularity compared to traditional case hardening processes. This process is used to produce a wide range of parts – particularly for the automotive industry – and features advantages like good case-depth uniformity and fast carbon transfer. Using multi-chamber systems like this enable high throughput but measuring temperature uniformity or product temperature profiles requires a through-process temperature profiling system like the Datapaq Furnace Tracker System from Fluke Process Instruments.

Get the Full Picture

By using a through-process thermal profiling system like the Datapaq Furnace Tracker, you can monitor the temperature of your products throughout the entire process to gain a better understanding of what is happening inside your furnace. Each system can also send real-time data via high-temperature radio telemetry, even when your application involves multiple vacuum chambers.

Reduce Temperature Uniformity Survey Times

In vacuum furnace application, through-process profiling systems allow for thermocouples to be set up, connected and checked offline – eliminating the need for feedthroughs and reducing furnace downtime. Additionally, without the proper software, producing reports that prove your compliance can be both time consuming and prone to errors. With Datapaq’s Insight™ Software, automated report options can help you reduce reporting times from hours to mere minutes as well as minimize the risk for any data entry errors.

Optimize Set-Up Times

Ensuring every product in the rack or basket meets thermal specification is critical to nearly any vacuum carburizing process. To better optimize your process, our Datapaq solution uses up to 20 thermocouples to gather full, detailed mappings and temperature data that show the full furnace working volume at every stage of the process – including during the gas quench.

Monitor Temperatures During Quench

Because quenching is crucial to the final surface hardness of a product, the Datapaq Furnace Tracker can measure temperatures up to 10 times every second. This provides the resolution most heat treatment facilities need to verify this fast quenching process.

Thermal Profiling Systems
  • Confirm furnace compliance to CQI-9 with a dedicated software and hardware package
  • Monitor the full product thermal profile, including soaking and pressure quench
  • Use as an R&D tool for OEMs in the design of new furnaces especially the quench design
