Infrared Temperature Measurement in Steel Processing
Use Raytek noncontact infrared thermometers in steel manufacturing process where temperature monitoring is critical to productivity and product quality. Every section of the steel manufacturing can benefit from temperature monitoring. Note that our product recommendations are based on the most common applications, for specific needs please contact our application engineers.
Raw Materials for Steel Production
Monitoring temperatures of iron ore, lime, coal and coke insures that the basic raw materials have achieved the right characteristics and prevents critical conveyor belts from being damaged. Continuous scans of stove dome temperatures is a requirement for maintaining correct operation of the blast furnace. Recommended products: ThermoView™ Pi20 Fixed Thermal Imager, Thermalert TX, Marathon MM, Marathon MR, MP150 Process Imager, Raynger 3i Plus Portable Thermometer.
Steelmaking – Blast Furnace
Stove dome: Thermal scans prevent overheating and premature damage to the refractory bricks.
Molten iron: Temperature monitoring during tapping ensures continuous feedback and product uniformity.
Torpedo car: Linescanning finds refractory failures and avoids costly and dangerous metal spills. Recommended Products: Marathon MM, Marathon MR, Marathon FR, Raynger 3i Plus Portable Thermometer.
Using infrared thermometers accurately gauge cooling requirements of slabs, billets, or blooms to ensure product uniformity throughout, and provide equipment operators with immediate temperature information vital to the cooling process. Recommended Products: Marathon FA, Marathon MR, Marathon FR, Raynger 3i Plus Portable Thermometer.
Infrared temperature sensors accurately measure strip and sheet temperature so that rolling mill stands can be efficiently set to match the steel’s temperature. IR sensors can also be used to detect the presence of hot metal to accurately time roll stand operation. Recommended Products: Marathon MM, Marathon MR, Marathon FR, Raynger 3i Plus Portable Thermometer.
Welded tube relies on accurate measurement of weld seem temperatures to insure 100% integrity of the seal and prevent bad or low quality tube. Monitoring the billet temperature in pipe mills allows the operator to adjust rollers, which results in reduced process downtime. Recommended Products: Marathon MM, Marathon FR, MP150 Process Imager, Raynger 3i Plus Portable Thermometer.
Thermal scans of billet exit temperatures allows the operator to adjust rollers and reduce process downtime. Sensors mounted at the layering area control cooling of overlapping coils to improve product quality. Recommended Products: Marathon MM, Marathon MR, MP150 Process Imager, Raynger 3i Plus Portable Thermometer.
Ratio IR thermometers allow accurate temperature measurement of parts often obscured by smoke, steam, and quench oil in an EMI environment. Factory operators can selectively control temperature measurement of heat treated parts, resulting in significant energy and time savings. Recommended Products: Marathon Series, Raytek MI3, Raynger 3i Plus Portable Thermometer.
Sheet temperatures can be monitored before and after coating to insure the coating will bond and have the desired thickness. Recommended Products: Marathon MM and Raynger 3i Plus Portable Thermometer.
Infrared sensors measure work-piece temperatures without interfering with the process to insure that correct metallurgical properties, such as grain size and structure are achieved. Monitoring temperature reduces heating costs by preventing billet overheating and reduces machine and die maintenance by identifying under heated billets before working. Recommended Products: Marathon MM, Marathon MR, Marathon FR, Raynger 3i Plus Portable Thermometer.
