In Foundry applications and the Iron and Steel industry in general, temperature readings help control to ensure that the correct heating or cooling is applied. Benefits in getting these temperatures right, include the following:
- Higher quality products
- Increased productivity
- Reduced rework
- Enhanced worker safety
- Reduced downtime
- Easy data recording
- Reduced energy costs
By utilizing infrared non-contact thermometers, each stage can be accurately monitored so the steel retains correct metallurgical properties as it travels through the process.
Infrared sensors take temperature measurement one step further. Simultaneous analog and digital output allows temperature data to be integrated into a closed loop control system and simultaneously output for remote temperature monitoring and analysis.
The smart sensors, with digital electronics and 2-way communications, can be configured remotely from the safety of the control room – especially important for metals with changing emissivities. The result: increased functionality and greater control.
Having recently joined forces to become one of the world’s largest suppliers of Infrared Temperature measurement equipment, Raytek and Ircon are able to offer noncontact infrared thermometers and scanners to cover every aspect of temperature monitoring in the steel manufacturing processes.
Where monitoring and controlling temperature is critical to productivity and product quality, Raytek/Ircon have an answer.
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.
A wide range of optics, including a remote controlled, motorized variable focus, covers an enormous variety of applications. This is supported by integrated through-the-lens sighting, plus either laser or video sighting for correct target location.
Accurate ongoing temperature measurements are crucial throughout the steel making process to produce quality products and enhance process efficiency. You will find both Raytek and Ircon Infrared detectors in all sectors of the steel making process but now they have available more specialsed units for specific applications covering:
- Torpedo car inspection
- Coke car inspection
