PROCESS CONTROL BY NON-CONTACT TEMPERATURE MEASUREMENTS IN FORGING APPLICATIONS
There are two main forging processes used in industry: drop forging and press forging. Accurate temperature monitoring is vital in both scenarios. In this guide, we take a closer look at the processes, the challenges, and how non-contact temperature measurement solutions can improve production quality, efficiency and process control.

THE ROLE OF TEMPERATURE MEASUREMENT IN SUSTAINABLE STEELMAKING
The steel industry is responsible for approximately 7% of global manmade CO2 emissions. Finding a way to meet ongoing demands for the quantity and quality of steel required, while reducing and eventually eliminating carbon emissions, is a major challenge for everyone involved in steel production.
Temperature monitoring solutions can help in the transition to more sustainable methods of steelmaking, supporting decarbonisation in a number of ways. This technology is also suitable for use with a range of fuels, supporting the transition to hydrogen as a carbon-free fuel source.

IMPROVING SAFETY AND QUALITY IN CONTINUOUS CASTING MACHINE (CCM) LIQUID METAL APPLICATIONS
Accurate temperature measurement of liquid metal during melting and pouring is important to ensure high-quality casting and efficient process operation. Traditional dip thermocouples present challenges for safety and measurement consistency, as well as incurring significant ongoing costs.
As the leading specialist in infrared non-contact temperature measurements for global industry, with extensive experience in liquid metal applications, LAND can supply a thermal imaging system to support process optimisation and safety at the point where the liquid metal stream leaves the tundish to moulds at the CCM billet caster.

TEMPERATURE MEASUREMENTS IN HEAT TREATMENT PROCESSES
Heat treatment is essential for the targeted influencing of important material and surface properties, such as softening a part, hardening its surface, or annealing stresses.
All of these processes involve precise temperature control in order to obtain the desired properties and guarantee their quality.

INFRARED 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.

ADVANTAGES 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.

PROCESS OPTIMISATION 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
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.

BLAST 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.

COLD 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
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.
