Infrared Process Imaging Systems For Vertical Continuous Annealing Lines - Application Note ENINFRARED PROCESS IMAGING SYSTEMS FOR VERTICAL CONTINUOUS ANNEALING LINES

 
The continuous annealing line is used to modify the grain structure of steel through heat treatment, changing properties including hardness and strength. The process involves several stages, focused on controlled heating and cooling to produce steel with the required qualities. Accurate temperature monitoring and control in each zone is essential for process and quality control. To ensure the accurate, edge-to-edge temperature monitoring required, a solution has been devised that overcomes the challenges caused by surface reflections and strip emissivity.

Application Note - Flare Stack MonitoringADVANTAGES OF THERMAL IMAGING FOR EFFECTIVE FLARE STACK MONITORING

Flare stacks are widely used in industries especially chemical, petrochemical and steel to safely dispose of excess gasses through combustion. These may be unwanted waste gases, or flammable gases released to prevent unplanned over-pressurising of  plant equipment. Simply venting these untreated hydrocarbons into the air creates an environmental hazard. Burning these gases is less harmful – for example, if methane is burned to produce carbon dioxide and steam, it is less damaging than releasing methane.

Application Note - Temperature Measurements in Reheat FurnacesTEMPERATURE MEASUREMENT IN METAL REHEAT FURNACES

Reheat furnaces bring cold metal to the correct temperature for rolling, extruding or forging. For optimum quality, and to reduce wastage, the temperature should be uniform throughout the product, which requires accurate temperature monitoring.

Coke Oven Temperature Measurement - Application Note (EN)COKE OVEN TEMPERATURE MEASUREMENT

High-quality metallurgical coke is a vital raw material for iron and steel production, affecting the furnace operation and standard of the hot metal. It is produced by heating coal in a coke oven in the absence of oxygen. Both the quality and quantity of coke, as well as the lifespan of the oven, depend upon uniform temperature levels, so these require close monitoring.

Application Note - Blast FurnaceBLAST FURNACE, STOVE DOME AND HOT BLAST MAIN

The quality and composition of iron produced in the blast furnace is directly related to the hearth temperature. This, in turn, is dependent on the temperature of the hot blast delivered from the blast furnace stoves. To maximise the efficiency of the stoves, they are operated at high temperatures, close to the safe working limit of the refractories. This makes it critical to carefully monitor the stove temperature.

Application Note - Temperature Measurements of The Ladle FreeboardTEMPERATURE MEASUREMENTS OF THE LADLE FREEBOARD

For safety and efficiency, it is essential to monitor the steel level as the ladle is filled with molten metal. This is accomplished by measurements of the ladle freeboard, the area of the ladle between the top edge and the surface of the molten metal inside it.

Cold Rolling Mill Strip Temperature Measurements Application NoteCOLD ROLLING MILL STRIP TEMPERATURE MEASUREMENTS

Non-contact temperature measurement directly on the cold rolled metal surface can be challenging. There may be relatively low temperatures and variable emissivity involved, and the background environment may create reflections which disturb the measurement conditions.

Molten Metal Escapes and Breakouts - Application NoteMOLTEN METAL ESCAPES AND BREAKOUTS

The escape or breakout of molten metal is a highly important safety consideration in all metal manufacturing industries, particularly steelmaking. The extremely high temperatures involved make any breakout of molten metal extremely hazardous. However, if the metal mixes with water, it can instantly vaporise the water, causing a potentially explosive reaction.
