How to Accurately Detect Heat Discrepancies in Rolled Steel

The AutoJet Temperature Profile Detector System provides an efficient way to measure multiple temperatures simultaneously across the entire roll width. Temperature data is immediately stored for easy retrieval when needed, automatically tagged with all important information such as the time and date of the measurement, the location or description, and the data itself.

Each sensor of the Temperature Profile Detector (TPD) measures the actual surface temperature by conduction, which is the most reliable method of temperature acquisition. The system is used by a single operator, and all data for a roll or strip may be accurately recorded within 30 seconds. The data is wirelessly transferred to an industry-standard SQL database. For normal, stand-alone use, the TPD operator does not have to operate on a Windows computer. Wireless communication for this system has been developed to allow for approximate range of 240m to 300m transmission distance, through walls and floors as needed, and this has been tested and proven to work in actual mill environments. All the data is carefully encoded at the point of transmission and checked for integrity at the receiving end.

The Temperature Profile Detector assists in quickly and accurately identifying hot or cold spots on the roll or strip surface (temperature profile). Better shape control can be achieved through accurate data for model tuning. The system can also help identify potential maintenance issues with cooling systems before they become a problem.

The Temperature Profile Detector system is controlled by the AutoJet TempTracker Pro® Software. Within this software, the user will create descriptions for intended measurement locations that are easy to understand for the user. This text can now be easily selected by the operator and is saved with the temperature data. Data may be recalled through using a flexible and powerful search feature in the AutoJet TempTracker Pro® software. Alternatively, the TPD unit may be used to record readings automatically over time to measure cooling or heating patterns.

Traditional methods are time consuming and inaccurate due to the inability to take a temperature reading across the entire width at once. With traditional methods, the time it takes between the first and last measurements allows for temperature changes and is also typically not done in small increments.

Here is some feedback from our customers about units we have sold to some of the largest steel producers in the world:

“We love the ability to take instant readings on the entire roll. The ability to view the temperature profiles of the rolls and identify temperature spikes and dips is very valuable for us to identify cooling problems before this affects our rolls”

“The data logging is great. We can go through the history and track any changes and trends in roll temperature”

The TPD will save you time and money and is a valuable tool for any Steel Mill to have.
