Non-contact infrared thermometers are ideal for use in steel manufacturing processes where monitoring and controlling temperature is critical to productivity and product quality.
Temperature readings show whether processes are operating within their proper ranges, whether a re-heater is too cold or too hot, whether a stand needs adjusting, or how much cooling should be applied. Each stage can be accurately monitored so the steel retains correct metallurgical properties as it travels through the milling process.
The benefits of accurate temperature monitoring and control in steel manufacturing include:
* Higher quality products.
* Increased productivity.
* Reduced energy costs.
* Enhanced worker safety.
* Reduced downtime.
* Easy data recording.
Raytek infrared sensors provide simultaneous analogue and digital output signals that allows temperature data to be integrated into a closed loop control system and also output for remote temperature monitoring and analysis.
Continuous casting
At the continuous caster where molten steel begins its transformation into slabs, billets, or blooms, productivity problems can slow or shut down an entire plant. Accurate realtime temperature monitoring coupled with the ability to adjust water nozzles and water flow rates allow for proper cooling, which helps maintain metallurgical properties. The results are better quality products, higher levels of productivity, and longer equipment life. The type and model of sensor is governed by the type of process and the sensor's location. For the harsh, dirty environments where the line of sight is obscured by dust, water spray, or steam, infrared ratio thermometers, such as the Raytek Marathon FR fibre-optic sensors and MR integrated sensors are suitable. Where edge-to-edge temperature profiles are needed then an MP50 linescanner is appropriate.

The Raytek Marathon series of IR thermometers is designed for harsh operating environments. These integrated units offer advanced electro-optics, smart digital electronics, and a built-in user interface in a rugged, compact housing.
Windows software is available to provide remote temperature monitoring, control, and analysis. This means that users can view realtime and saved thermal images, and correct process irregularities before they become problems.
